maxillary artery three parts branches supply anatomy MBBS

Detailed medical anatomy diagram for MBBS seminar presentation titled "MAXILLARY ARTERY - PART 1: MANDIBULAR PART". Clean white background, professional medical illustration style with bold red arterial lines and clear black labels. Show the maxillary artery origin from external carotid artery, passing between the neck of the mandible and the sphenomandibular ligament. Label this segment clearly as "1st Part (Mandibular Part) - Lies between neck of mandible and sphenomandibular ligament". Show 5 branches emerging from this part with color-coded arrows pointing to their supply areas: 1. DEEP AURICULAR ARTERY - arrow pointing to: external auditory meatus, tympanic membrane outer surface. Label "Supply: EAM + outer tympanic membrane" 2. ANTERIOR TYMPANIC ARTERY - arrow pointing to inner surface of tympanic membrane. Label "Supply: Inner surface of tympanic membrane" 3. MIDDLE MENINGEAL ARTERY (largest branch, shown prominently) - ascending through foramen spinosum, entering cranial cavity, branching into anterior and posterior divisions over temporal bone. Label "Supply: Dura mater, pericranium, temporal bone, bone marrow. LARGEST MENINGEAL VESSEL. Enters via Foramen Spinosum. Passes between 2 roots of auriculotemporal nerve." 4. ACCESSORY MENINGEAL ARTERY - passing through foramen ovale. Label "Supply: Trigeminal ganglion, dura mater, medial pterygoid muscle" 5. INFERIOR ALVEOLAR ARTERY - descending with inferior alveolar nerve into mandibular foramen. Show its 3 branches: Mental artery (exits mental foramen, supplies chin/lower lip), Incisive branch (supplies incisors/canines), Mylohyoid branch (supplies mylohyoid muscle). Label "Supply: Mandibular teeth, gums, lower lip, chin, mylohyoid" Add a small inset box showing clinical significance: "MIDDLE MENINGEAL ARTERY rupture → Extradural (Epidural) Hematoma - lucid interval then deterioration" Use a clean hierarchical flowchart-style layout with the artery trunk on the left and branches extending to the right. Bold title at top. Include mnemonic at bottom: "Mnemonic: DAAIM - Deep auricular, Anterior tympanic, Accessory meningeal, Inferior alveolar, Middle meningeal"

Detailed medical anatomy diagram for MBBS seminar presentation titled "MAXILLARY ARTERY - PART 2: PTERYGOID PART". Clean white background, professional medical illustration style with bold red arterial lines and clear black labels. Show the maxillary artery trunk running lateral (or medial) to the lateral pterygoid muscle. Label this segment clearly as "2nd Part (Pterygoid Part) - Lies on or related to lateral pterygoid muscle. Supplies muscles of mastication." Show 5 branches as red arterial lines with labels. All branches supply SOFT TISSUES (no bony foramina involved - highlight this fact in a callout box). Branches: 1. ANTERIOR DEEP TEMPORAL ARTERY - ascending to anterior part of temporalis muscle. Label "Supply: Anterior temporalis muscle" 2. POSTERIOR DEEP TEMPORAL ARTERY - ascending to posterior temporalis. Label "Supply: Posterior temporalis muscle" 3. PTERYGOID BRANCHES (medial and lateral) - short branches to pterygoid muscles. Label "Supply: Medial and lateral pterygoid muscles" 4. MASSETERIC ARTERY - passing through mandibular notch to masseter. Label "Supply: Masseter muscle (enters via mandibular notch)" 5. BUCCAL ARTERY - running with long buccal nerve to buccinator. Label "Supply: Buccinator muscle, buccal mucosa, buccal gingiva" Draw a schematic lateral view of the infratemporal fossa with: - Lateral pterygoid muscle shown prominently (shaded in yellow/tan) as the key landmark - Temporalis muscle visible above - Masseter visible laterally - Pterygoid muscles shown medially - The maxillary artery trunk passing along the lateral pterygoid Add a highlighted box: "KEY FACT: All 2nd part branches supply muscles of mastication. NO branches pass through bony foramina." Add a comparison box at bottom showing all 3 parts side by side for context, with Part 2 highlighted. Bold title at top. Add mnemonic: "Mnemonic: 2 Deep Temporal + 2 Pterygoid + Masseteric + Buccal = 6 branches (or PDMBBT)"

Detailed medical anatomy diagram for MBBS seminar presentation titled "MAXILLARY ARTERY - PART 3: PTERYGOPALATINE PART". Clean white background, professional medical illustration style with bold red arterial lines and clear anatomical labels. Show the maxillary artery entering the pterygopalatine fossa through the pterygomaxillary fissure. Label: "3rd Part (Pterygopalatine Part) - lies in pterygopalatine fossa, anterior to pterygopalatine ganglion" Show 6 terminal branches with their courses and supply areas in a fan-like arrangement: 1. POSTERIOR SUPERIOR ALVEOLAR ARTERY - descending through alveolar foramina on infratemporal surface of maxilla. Label "Supply: Upper molar and premolar teeth, adjacent gingiva, maxillary sinus. Given off at pterygomaxillary fissure." 2. INFRA-ORBITAL ARTERY - passing through inferior orbital fissure → infra-orbital groove → infra-orbital canal → infra-orbital foramen. Show sub-branches: Anterior superior alveolar artery (incisors + canines + maxillary sinus). Label "Supply: Lower eyelid, upper lip, cheek, lacrimal sac, inferior rectus, inferior oblique muscles" 3. GREATER PALATINE ARTERY - descending in palatine canal → greater palatine foramen → hard palate → incisive canal. Show lesser palatine branch through lesser palatine foramen. Label "Supply: Hard palate, soft palate (via lesser palatine branch), anterior nasal septum (via incisive canal)" 4. PHARYNGEAL ARTERY - running posteriorly through palatovaginal canal. Label "Supply: Roof of pharynx, soft palate, auditory tube (Eustachian tube), sphenoidal sinus" 5. ARTERY OF PTERYGOID CANAL (Vidian Artery) - passing through pterygoid canal alongside Vidian nerve. Label "Supply: Upper pharynx, auditory tube, pterygoid canal structures" 6. SPHENOPALATINE ARTERY (terminal branch, shown largest) - passing through sphenopalatine foramen into nasal cavity. Show branches: posterior lateral nasal branches + posterior septal branches. Label "TERMINAL BRANCH. Supply: Lateral nasal wall, nasal septum. MOST COMMON SOURCE OF POSTERIOR EPISTAXIS. Also called 'artery of epistaxis'" Add a clinical pearl box: "SPHENOPALATINE ARTERY = Most common source of severe posterior nosebleeds (epistaxis). Surgical ligation performed endoscopically." Add a small anatomical context box showing pterygopalatine fossa connections: → inferior orbital fissure (to orbit), → pterygomaxillary fissure (to infratemporal fossa), → foramen rotundum (to cranial cavity), → palatine canal (to palate), → sphenopalatine foramen (to nasal cavity) Bold title at top in dark blue/navy.
