Lower limb 2 Flashcards
Pelvic girdle is completed anteriorly and posteriorly by what
Anteriorly - pubic symphysis
Posteriorly - sacroiliac joints
Which sciatic foramen is the route for structures entering/leaving pelvis
Greater
Which sciatic foramen is the route for structures entering/leaving the perineum
Lesser
Note where ischial spine is - pg 110
.
What does the sacrospinous ligament connect
Outer edge of sacrum and coccyx to ischial spine
List the 4 muscles of the superficial layer of the gluteal region + what 2 actions do these muscles mainly carry out
(there is superficial and deep layer)
Gluteus maximus
Gluteus medius
Gluteus minimus
Tensor fascia latae
ABDUCTION + EXTENSION
List the 5 muscles of the deep layer of the gluteal region + what is their main action
Quadratus femoris Piriformis Gemellus superior Gemellus inferior Obturator internus
LATERAL ROTATION
The fascia lata is the deep fascia of the thigh. It encloses the thigh muscles.
What is the iliotibial tract/band
Extension of the fascia lata on the lateral side of thigh
What 2 muscles are attached to the iliotibial tract
Tensor fascia latae and gluteus maximus
Actions of gluteus maximus (2)
Extend hip
Laterally rotate hip
Innervation of gluteus maximus
Inferior gluteal nerve
Actions of gluteus medius (2)
Abduct + medially rotate hip
Actions of gluteus minimus (2)
Abduct + medially rotate hip
Actions of tensor fascia latae
Assists the gluteus medius and minimus in abduction and medial rotation of hip
Innervation of gluteus medius, minimus and tensor fascia latae
Superior gluteal nerve
Function of the deep muscles of the gluteal region (i.e. Quadratus femoris, Piriformis, Gemellus superior, Gemellus inferior, Obturator internus) (2)
Stabilise the hip joint by ‘pulling’ the femoral head into the acetabulum of the pelvis
Laterally rotate hip
Nerve roots of sacral plexus
Ventral rami of L2-S4
