Gluteal Muscles and Hip Joint Flashcards
Where does the gluteus maximus attach?
To the gluteal tuberosity
On the posterior aspect of the femur
2 ligaments in the pelvis
Sacrospinous ligament
Sacrotuberous ligament
Sacrospinous ligament
Connects the sacrum to the ischial spine
Closes off the greater sciatic foramen
Sacrotuberous ligament
Connects the sacrum and the ischial tuberosity
Closes off the lesser sciatic foramen
Gluteus maximus (connections and functions)
Connects ilium to the gluteal tuberosity and IT band
Extends and laterally rotates the femur
What nerve innervates the gluteus maximus? What spinal nerves is it from?
Inferior gluteal nerve
L5, S1, S2
Gluteus medius (connections and functions)
Posterior surface of the ilium to the greater trochanter
Abducts and medially rotates the femur
What nerve innervates the gluteus medius? What spinal nerves is it from?
Superior gluteal nerve
L4, L5, S1
Gluteus minimis functions
Abducts and medially rotates the femur
What nerve innervates the gluteus minimus? What spinal nerves is it from?
Superior gluteal nerve
L4, L5, S1
6 short lateral rotators
Piriformis Superior gemellus Inferior gemellus Obturator internus Quadratus femoris Obturator externus
The superior and inferior neurovascular bundles leave through where?
The greater sciatic foramen
What leaves
1. Above
2. Below
the piriformis?
- Superior gluteal nerve, artery and vein
2. Inferior gluteal bundle (artery, vein, nerve) and the sciatic nerve
Sciatic nerve (spinal nerves, innervates what, branches)
L4, L5, S1, S2, S3
Innervates all muscles of the posterior compartment of the thigh
Branches into the tibial and common peroneal nerves
What structures leave the pelvis through the greater sciatic foramen? (4)
Piriformis muscle
Sciatic nerve
Superior and inferior gluteal bundles
Pudendal nerve
