Gluteal Muscles Flashcards
connective tissue = _______
fascia
describe superficial fascia
-loose c.t
-holds fat and h2o
-nerves and vessels travel in this
describe deep fascia
-dense c.t
-compartmentalize muscles (in thigh = fascia lata. in leg = crural fascia)
-muscles attachment
An A attachment for a muscle means
it’s the proximal attachment (origin)
a B attachment for a muscle means
distal attachment (insertion)
what does the innervation of a muscle refer to
the motor nerve
what does the function of a muscle refer to
depends on the movement
what does the action of a muscle refer to
whether the muscle shortens/contracts
what is the action of the glut. max muscle
-extension of the hip/thigh
-lateral rotation of hip
what is the innervation of the glut. max muscle
inferior gluteal nerve
describe the glut. max muscle attachments
-sacrum, sacrotuberous ligament which goes to the gluteal tuberosity of femur and iliotibial tract
what is the function of glut max muscle
when walking = limits hip flexion
when running/climbing= hip extension
describe the tensor fascia latae attachments (TFL)
iliac crest –> illiotibial tract
what is the action of the TFL
-hip flexion
-medially rotate hip
-hip abduction
what is the function of the TFL
lateral stabilization of hip and knee
what is the innervation of the TFL
superior gluteal nerve
describe the glut. medius and minimus attachments
gluteal surface of illium –> greater trochanter of femur
what is the action of the glut. medius and minimus
-abduct the hip
-medial rotation of the hip
what is the function of the glut medius and minimus
to limit adduction of the hip
what is the innervation of the glut. medius and minimus
superior gluteal nerve
describe the attachments of the hip intrinsics
sacrum/ilium –> lateral femur
what is the action of hip intrinsics muscle
extend the hip, laterally rotate the hip
what is the function of the hip intrinsics muscle
proprioception of hip
name the hip intrinsic muscles from superior to inferior
-piriformis muscle
-superior gemellus muscle
-obturator internus muscle
-inferior gemellus muscle
-quadratus femoris muscle
