Most medial hamstring muscle located posteromedially in thigh. Originates from superolateral aspect of ischial tuberosity. Wider, flatter, and deeper than semitendinosus muscle. Overlaps upper part of popliteal vessels
Long superficial muscle located in back of thigh. Arises from ischial tuberosity via common tendon with biceps femoris. Forms pes anserinus with sartorius and gracilis tendons. Innervated by tibial nerve through sacral plexus (L5-S2)
Longest muscle in human body running down thigh's anterior compartment. Originates from anterior superior iliac spine and runs inferomedially. Ends in tendon joining gracilis and semitendinosus in pes anserinus. Forms lateral border of femoral triangle
Fish fins are movable appendages that generate thrust and help swim. Most fins are unpaired (dorsal, anal, caudal) and paired (pectoral, pelvic). Fins are supported only by muscles, not directly connected to back bone
Glycogen is the body's stored form of glucose. Made from connected glucose molecules stored in liver and muscles. Most carbohydrates are converted to glucose for energy
The sartorius is the longest muscle in the body, running from pelvis to knee. It starts at ASIS and inserts into pes anserine (goosefoot). The muscle can be palpated by flexing thigh and rotating it outward
