Here is the full identification for each spot:

SPOT-by-SPOT Identification

Spot 1 - Posterior Leg Dissection (Labels B on calcaneal tendon)

Specimen: Posterior compartment of the leg / popliteal fossa dissection

Label	Structure
B (distal, on thick tendon)	Calcaneal (Achilles) tendon - the thickest tendon in the body, formed by the union of gastrocnemius and soleus tendons, inserting into the posterior calcaneus
B (proximal, popliteal fossa)	Tibial nerve - the larger terminal branch of the sciatic nerve, running down the midline of the popliteal fossa

Other visible structures: Gastrocnemius (medial and lateral heads), Soleus muscle deep to it.

Spot 2 - Medial Thigh Dissection (Labels A and B)

Specimen: Anteromedial thigh dissection

Label	Structure
A	Sartorius muscle - the longest muscle in the body, running obliquely from ASIS to the pes anserinus
B	Saphenous nerve (or femoral nerve branch) - the longest cutaneous nerve, running in the adductor canal deep to sartorius

Spot 3 - Brain Dissection (Labels A and B with colored pins)

Specimen: Human brain - ventral/basal view (Circle of Willis)

Label	Structure
A (pink pin)	Anterior Cerebral Artery (ACA) - courses anteriorly toward the interhemispheric fissure between the frontal lobes
B (green pin)	Middle Cerebral Artery (MCA) - the large lateral branch from the internal carotid bifurcation, coursing toward the lateral sulcus

Spot 4 - Heart Dissection (Labels A and B)

Specimen: Human Heart (anterior/superior view)

Label	Structure
A	Arch of Aorta (ascending aorta / superior great vessel)
B	Left Ventricle (inferolateral wall of the heart)

SPOT-14 - Heart in Tray (Labels A and B)

Organ: Heart

Label	Structure
A	Arch of Aorta (great vessel emerging from the superior aspect)
B	Left Ventricle (the prominent muscular inferior chamber)

Histology Slides (SPOT-6 and nearby microscopy images)

The question card reads: SPOT-6 - "1. Identify the slide. 2. Write down any two identifying features."

Based on the microscopy images visible:

Slide 1 (pale/low contrast image):

Alternating dark (cellular) and pale bands of lymphoid tissue
Consistent with Lymph node (cortex with follicles, medullary cords/sinuses visible)

Slide 2 (vivid pink/purple - gastric rugae pattern):

Tall columnar surface epithelium with deep gastric pits
Dense lamina propria with glands below
Identification: Stomach (Fundus/Body)
Two identifying features: (1) Gastric pits lined by columnar epithelium; (2) Gastric glands (fundic glands) in the lamina propria

Slide 3 (purple - lymphoid tissue with goblet cells in center):

Lymphoid follicles on both sides (cortex)
Central column of large goblet cells / mucinous glands
Identification: Appendix (or large intestine junction with lymphoid aggregates)
Two identifying features: (1) Numerous lymphoid follicles in the wall; (2) Goblet cell-rich columnar epithelium lining the lumen

Note: For the histology spots, the image quality through the eyepiece makes exact identification challenging. The stomach slide is the most confidently identified based on the classic gastric pit and gland pattern. The lymphoid-rich slide with goblet cells strongly suggests appendix.
