Muscles of the gluteal region Flashcards
Name the superficial muscles of the gluteal region and the movements they produce
Abduction and extension of the femur/thigh
Gluteus maximus
Gluteus medius
Gluteus minimus
Tensor fascia latae
Name the deep muscles of the gluteal region and the movement they perform
Laterally rotate the femur/thigh
Quadratus femoris
Piriformis
Superior gemellus
Inferior gemellus
Obturator internus
Gluteus maximus: attachments, actions and innervations
Originates from gluteal surface of ilium, sacrum and coccyx. Inserts into iliotibial tract and gluteal tuberosity of femur
Main extensor of thigh
Inferior gluteal nerve
Gluteus medius: attachments, actions and innervations
Originates from gluteal surface of ilium, inserts into lateral surface of greater trochanter
Abducts and medially rotates lower limb
Superior gluteal nerve
Gluteus minimus: attachments, actions and innervations
Originates from ilium and converges to form a tendon inserting into anterior side of greater trochanter
Abducts and medially rotates lower limb
Superior gluteal nerve
Tensor fascia latae: attachments, actions and innervations
Originates from anterior superior iliac spine and then inserts into iliotibial tract
Abduction and medial rotation of lower limb
Superior gluteal nerve
Piriformis: attachments, actions and innervations
Originates from anterior surface of sacrum and inserts into greater trochanter
Lateral rotation and abduction of lower limb
Nerve to piriformis
Obturator internus: attachments, actions and innervations
Originates from obturator foramen and attaches to greater trochanter
Lateraly rotation and abduction of lower limb
Nerve to obturator internus
Superior and inferior gemelli: attachments, actions and innervations
Superior from ischial spine and inferior from ischial tuberosity. Both attach to greater trochanter.
Lateral rotation and abduction of lower limb
Superior by nerve to obturator internus, inferior by nerve to quadratus femoris
Quadratus femoris: attachments, actions and innervations
Originates from lateral side of ischial tuberosity, attaches to quadrate tuberosity on intertrochanteric crest
Lateral rotation of lower limb
Nerve to quadratus femoris
