I now have comprehensive information from Gray's Anatomy for Students and Rockwood & Green's. Let me compile the complete answer.
Muscle Attachments of the Clavicle, Scapula, and Humerus
Sources: Gray's Anatomy for Students; Rockwood and Green's Fractures in Adults, 10th ed.
Scapula — Diagram
I. CLAVICLE
The clavicle connects the trunk to the upper limb and serves as the attachment site of several large muscles. Its surfaces and margins are roughened accordingly.
| Surface / Region | Muscle | Attachment Type |
|---|---|---|
| Anterior surface, medial 2/3 (inferior) | Pectoralis major (clavicular head) | Origin |
| Superior surface, medial end | Sternocleidomastoid | Insertion |
| Lateral 1/3 (anterior border + superior surface) | Deltoid (anterior part) | Origin |
| Lateral 1/3 (posterior border + superior surface) | Trapezius | Insertion |
| Inferior surface (medial to middle third) | Subclavius | Insertion |
| Subcutaneous tissues, anterior/superior | Platysma | Variable covering |
Clinical note: After a clavicle fracture, the medial fragment is elevated by the unopposed pull of the sternocleidomastoid, while the lateral fragment is pulled inferiorly by the deltoid and medially by the pectoralis major. — Rockwood & Green's, 10th ed.
II. SCAPULA
The scapula's thickened borders are attachment sites for 18 muscle origins and insertions. — Rosen's Emergency Medicine
A. Posterior Surface
| Feature | Muscle | Attachment Type |
|---|---|---|
| Supraspinous fossa | Supraspinatus | Origin |
| Infraspinous fossa | Infraspinatus | Origin |
| Spine of scapula (posterior surface, medial border to root of spine) | Trapezius | Insertion |
| Spine of scapula (inferior lip) | Deltoid | Origin |
| Medial border (superior angle → root of spine) | Levator scapulae | Insertion |
| Medial border (root of spine → inferior angle, posterior surface) | Rhomboid minor (root of spine) & Rhomboid major (inferior angle) | Insertion |
B. Costal (Anterior) Surface
| Feature | Muscle | Attachment Type |
|---|---|---|
| Subscapular fossa (entire costal surface) | Subscapularis | Origin |
| Costal surface and margins | Serratus anterior (lower digitations) | Insertion (along medial border) |
C. Lateral Angle & Glenoid Region
| Feature | Muscle | Attachment Type |
|---|---|---|
| Supraglenoid tubercle | Long head of biceps brachii | Origin |
| Infraglenoid tubercle | Long head of triceps brachii | Origin |
D. Coracoid Process
| Feature | Muscle | Attachment Type |
|---|---|---|
| Tip of coracoid process | Short head of biceps brachii | Origin |
| Tip of coracoid process | Coracobrachialis | Origin |
| Medial surface of coracoid | Pectoralis minor | Insertion |
E. Lateral Border
| Feature | Muscle | Attachment Type |
|---|---|---|
| Lateral border (posterior surface) | Teres minor (upper part) | Origin |
| Lateral border (inferior angle, posterior surface) | Teres major | Origin |
F. Superior Border
| Feature | Muscle | Attachment Type |
|---|---|---|
| Superior border (medial to suprascapular notch) | Omohyoid (inferior belly) | Origin |
III. HUMERUS (Proximal End)
A. Greater Tubercle (lateral — three facets)
| Facet | Muscle | Attachment Type |
|---|---|---|
| Superior facet | Supraspinatus | Insertion |
| Middle facet | Infraspinatus | Insertion |
| Inferior facet | Teres minor | Insertion |
B. Lesser Tubercle (anterior)
| Feature | Muscle | Attachment Type |
|---|---|---|
| Lesser tubercle (single large impression) | Subscapularis | Insertion |
These four muscles (supraspinatus, infraspinatus, teres minor, subscapularis) form the rotator cuff.
C. Intertubercular Sulcus (Bicipital Groove)
| Lip / Floor | Muscle | Attachment Type |
|---|---|---|
| Lateral lip | Pectoralis major | Insertion |
| Floor | Latissimus dorsi | Insertion |
| Medial lip | Teres major | Insertion |
The tendon of the long head of biceps brachii passes through the sulcus (not attached to it).
D. Shaft of Humerus
| Feature | Muscle | Attachment Type |
|---|---|---|
| Deltoid tuberosity (lateral surface, midshaft) | Deltoid | Insertion |
| Medial surface (opposite deltoid tuberosity, thin vertical roughening) | Coracobrachialis | Insertion |

Iran–US Tensions & Global Economic Impact
⚠️ Important Caveat
Live web search is currently unavailable, so I cannot pull today's breaking news. My knowledge extends to early 2026. For the very latest developments, check Reuters, BBC News, or Al Jazeera directly.
What Was Happening as of Early 2026
Military/Diplomatic Situation
- There is no declared war between Iran and the United States as of my knowledge cutoff. However, tensions have been extremely elevated through several flashpoints:
- Iran's nuclear program — Iran continued advancing uranium enrichment toward weapons-grade levels, with IAEA inspections increasingly restricted.
- US–Iran nuclear talks — Intermittent negotiations; no comprehensive deal was reached.
- Proxy conflict — Iran-backed groups (Houthis in Yemen, Hezbollah, Iraqi militias) engaged US forces and regional allies, with the US conducting retaliatory strikes in Syria, Iraq, and Yemen.
- Israeli strikes on Iran — In 2024, Israel and Iran exchanged direct strikes for the first time, with the US providing Israel defensive support.
- Strait of Hormuz threats — Iran repeatedly threatened to close the strait, through which ~20% of global oil passes.
Global Economic Impact (Cumulative Estimates)
Oil & Energy Markets
- Brent crude spiked repeatedly on escalation news, touching $90–$100+/barrel during peak tension periods.
- Houthi attacks on Red Sea shipping (Iran-backed) diverted hundreds of cargo ships around the Cape of Good Hope, adding 10–14 days and $1–2 million extra cost per voyage.
- Red Sea disruptions affected roughly 12–15% of global trade volume routed through that corridor.
Shipping & Trade
- Container freight rates surged 200–400% from pre-conflict baselines during peak Red Sea disruption (late 2023–2025).
- Global supply chains for goods from Asia to Europe and North America were significantly disrupted.
- Insurance (war risk premiums) for vessels in the region rose by 500–1000%.
Broader Economic Costs
- The IMF and World Bank flagged Middle East conflict as a top downside risk to global growth in 2024–2025 outlooks.
- Estimated drag on global GDP growth: roughly 0.3–0.5 percentage points depending on the scenario modeled.
- Iran's own economy contracted sharply under renewed/tightened US sanctions — inflation in Iran exceeded 40% in peak years.
- Global food prices were also affected, as the Red Sea is a critical route for grain shipments.
Key Numbers at a Glance
| Impact Area | Estimate |
|---|---|
| Oil price volatility | $80–$100+ per barrel (Brent) |
| Red Sea trade disruption | ~12–15% of global trade rerouted |
| Shipping freight rate increase | 200–400% above baseline |
| Global GDP drag | ~0.3–0.5 pp per year of sustained conflict |
| Iran domestic inflation | 40–50%+ |
| War risk insurance premium increase | 500–1000% |
What to Watch Now
- Iran nuclear negotiations — Any deal or breakdown has immediate oil market consequences.
- Strait of Hormuz — A closure would be a catastrophic shock (~$150+/barrel scenarios modeled by analysts).
- Houthi ceasefire status — US and Houthi forces reached a ceasefire agreement in early 2025 that was fragile.

Iran–US Conflict: World Economic Damage & Future of Oil
First — Clarifying "War"
There is no formally declared Iran–US war. What exists is a high-intensity, multi-front conflict involving:
- Direct US airstrikes on Iranian proxies in Iraq, Syria, Yemen
- Israeli strikes on Iran (April & October 2024) with US backing and intelligence support
- Iranian drone/missile attacks on Israel and US bases
- Iran-backed Houthi blockade of Red Sea shipping
- Maximum-pressure US sanctions on Iran's economy
This is functionally a shadow war with real economic consequences — not a conventional battlefield war. That distinction matters for economic analysis.
🌍 Global Economic Damage — Sector by Sector
1. Shipping & Trade
The Houthi Red Sea attacks (late 2023 onward) caused the single largest non-pandemic trade disruption in decades.
| Metric | Impact |
|---|---|
| % of global trade normally through Red Sea/Suez | ~12–15% |
| Ships rerouted via Cape of Good Hope | Hundreds per week at peak |
| Extra distance per voyage (Asia→Europe) | +3,500–4,000 nautical miles |
| Extra time per voyage | +10–14 days |
| Extra cost per container ship voyage | ~$1–2 million |
| Container freight rate increase (peak) | +300–400% above pre-conflict baseline |
| Suez Canal revenue loss (Egypt) | ~$7 billion/year lost (from ~$10B → ~$3B) |
2. Oil & Energy
| Metric | Impact |
|---|---|
| Brent crude price range (2024–2025) | $75–$100+ per barrel |
| Price spikes on escalation events | +5–10% within hours of strikes |
| Global oil supply at risk (Strait of Hormuz) | ~21 million barrels/day (~20% of global supply) |
| LNG disruption through Hormuz | ~25% of global LNG trade |
| Refinery margin increases | Passed to consumers as higher fuel prices |
3. Global GDP & Growth
- The IMF in its 2024–2025 World Economic Outlooks cited Middle East conflict as the #1 geopolitical downside risk
- Estimated GDP drag: 0.3–0.7 percentage points per year if conflict remains at current intensity
- A full Strait of Hormuz closure scenario was modeled to cause a $1 trillion+ global GDP shock in the first year
- Inflation in many countries got a second wind from energy/shipping costs, complicating central bank rate-cutting cycles
4. Food & Commodity Prices
- Red Sea is a major route for wheat, grain, and fertilizer shipments
- Global food price index stayed elevated partly due to shipping disruptions
- Countries most affected: South and Southeast Asia, East Africa, Southern Europe (dependent on Suez route imports)
5. Iran's Own Economy
| Metric | Status |
|---|---|
| Inflation | 40–50% at peak years |
| Currency (Iranian Rial) collapse | Lost ~80% of value vs. USD over the conflict period |
| Oil export revenue | Suppressed by sanctions, though China-linked smuggling partially offset this |
| GDP growth | Erratic; periods of near-recession |
| Unemployment | ~10–13% officially (widely considered understated) |
🛢️ Future of Oil & Petroleum Products — Scenarios
Scenario 1: Status Quo (Most Likely ~50%)
Tensions persist, no escalation to full war, no resolution
- Oil stays in the $70–$95/barrel range
- Red Sea disruptions continue at reduced but persistent levels
- OPEC+ uses conflict as justification to manage supply cuts
- Petroleum product prices remain elevated globally
- Petrol prices stay 15–25% above pre-2023 levels in most countries
Scenario 2: Diplomatic Resolution / Nuclear Deal (Possible ~20%)
Iran–US reach a framework agreement
- Iran's ~3 million barrels/day of suppressed exports return to market
- Brent crude could drop $10–20/barrel almost immediately
- Red Sea Houthi activity loses Iranian logistical support → shipping normalizes
- Global inflation relief, especially in Asia and Europe
- Petrol prices fall — potentially the biggest deflationary event since COVID demand collapse
Scenario 3: Major Escalation — Direct US–Iran War (~15%)
US strikes Iranian nuclear facilities or Iran strikes US assets directly
- Immediate closure or severe disruption of Strait of Hormuz
- Oil price shock to $120–$180/barrel (Goldman Sachs & JPMorgan worst-case models)
- Global recession risk rises sharply
- Petrol prices double in many markets within weeks
- Airlines, shipping, manufacturing — cascading shutdowns
- Central banks forced into impossible trade-off: inflation vs. recession
Scenario 4: Israel–Iran Escalation Draws in US (~15%)
Full Israeli–Iranian war, US dragged in
- Similar to Scenario 3 but potentially broader
- Gulf Arab states (Saudi Arabia, UAE) pressured to take sides
- Saudi oil infrastructure becomes a target (as in 2019 Abqaiq attack, but larger scale)
- Energy market paralysis scenario
Oil Supply Geography — Why Hormuz Matters So Much
Countries whose oil MUST pass through Strait of Hormuz:
• Saudi Arabia (most exports)
• UAE
• Kuwait
• Iraq
• Qatar (LNG)
• Iran itself
= ~21 million barrels/day
= ~20% of ALL oil traded globally
= ~25% of global LNG
There is no complete alternative pipeline route for this volume. The Saudi East–West pipeline (Petroline) and UAE's Fujairah pipeline can bypass Hormuz for only ~7 million barrels/day combined — leaving a massive gap in any closure scenario.
Impact on Petrol/Diesel Prices at the Pump
| Scenario | Expected Pump Price Change |
|---|---|
| Status quo continues | +10–20% vs. 2022 levels (already baked in) |
| Diplomatic deal | −10–15% relief |
| Major escalation/Hormuz closure | +50–100% in weeks |
| Prolonged full war | +80–150%; rationing likely in some countries |
Bottom Line
The conflict has already cost the global economy an estimated $300–500 billion+ in cumulative trade, energy, and growth losses since 2023 — with the Red Sea shipping crisis alone accounting for a significant share. The future trajectory depends almost entirely on whether the Strait of Hormuz remains open. That single 33-km-wide waterway is the most consequential chokepoint in global energy — and it sits entirely within Iran's threat range.
