Which muscle is correctly matched to its origin and insertion?
A) pectineus; originates on the crest of the ilium and inserts into the fascia lata
B) sartorius; originates on the ischium and pubic symphysis and inserts on the medial surface of the tibia
C) gracilis; originates on the ischial tuberosity and inserts on the tibia
D) gluteus medius; originates on the ilium and the transverse processes of the last sacral and first caudal vertebrae and inserts on the femur

Question

Quizplus · Accepted Answer

The gluteus medius muscle originates on the ilium, specifically the outer surface of the ilium between the iliac crest and the posterior gluteal line, as well as the transverse processes of the last sacral and first caudal vertebrae. Its insertion is on the greater trochanter of the femur. Option A is incorrect as the pectineus muscle originates from the pectineal line and superior ramus of the pubis and inserts on the pectineal line of the femur. Option B is incorrect as the sartorius muscle originates on the anterior superior iliac spine and inserts on the medial surface of the tibia. Option C is incorrect as the gracilis muscle originates on the pubic symphysis and ischiopubic ramus and inserts on the medial surface of the tibia.
