What is the innervation of inferior gemellus and quadratus femoris

Nerve to quadratus femoris

Describe piriformis syndrome, symptoms, and common activities that cause it

Label the nerve innervation and the muscle

Where should intramuscular injections be applied

What muscles are supplied by the superior gluteal artery

Glute max, med, min, and TFL

What are the nerves that make up the posterior compartment

Sciatic nerve that branches into: 1. Tibial nerve 2. Common fibular nerve

T or F: The sciatic nerve is so large it has its own blood supply

T, called artery to sciatic

Label the blood supply of the posterior compartment
