Question 10

What are the orgin and insertions of the superior and inferior gemelli?

Answer 10

Superior orginates from the ischial spine, and inferior orginates from the ischial tuberosity.

Question 11

Answer 11

Origin is the lateral side of the ischial tuberosity, and the insertion is the intertrochnateric crest.

Question 12

Innervates the gleutus medisu and gletusu minimus, whcihc stabilise the pelvis during locomotion, and the trendenlberg sign is seen when the patient is asked to stand unassisted on each leg.

Question 15

What are some of the features of the sciatic nerve?

Answer 15

Dervived from the lumbroscaracal plexus, from roots L4 to S3, and emerges inferiorly from the piriformis before innervating the muscles of the posterior thigh, before biuficurating in the posterior thigh

Question 16

What is the clinical relevance of the sciatic nerve?

Answer 16

To avoid the sciatic nerve intramuscular injections should be given in the upper lateral quadrant of the piriformis muscle.
