Gluteal region and posterior thigh Flashcards
What covers the gluteus medius
gluteal aponeurosis
The gluteus medius completely covers the
gluteus minimus
The muscles superior and inferior to the obturator internus muscle are the
superior and inferior gemelli

obturator internus
Inferior to the inferior gemellus is the ___ muscle
quadratus femoris

inferior gemellus and quadratus femoris
The hamstrings consists of ____ m, ____ m, and ____ m
semimembranosus, semitendinosus, and long head of biceps femoris
The greater sciatic notch and sacrospinous and sacrotuberous ligaments make up the
greater sciatic foramen
The lesser sciatic notch and sacrospinous and sacrotuberous ligaments make up the
lesser sciatic foramen
Things exiting the pelvis and entering the gluteal foramen run through the
greater sciatic foramen
Things exiting the pelvis and entering into the gluteal foramen OR that enter back into the pelvis after exiting the greater foramen go through the
lesser sciatic foramen
The piriformis muscle exits the pelvis via the
greater sciatic foramen
The sciatic nerve, posterior cutaneous nerve of the thigh, superior and inferior gluteal nerves, nerve to quadratus femoris, nerve to obturator internus, and pudendal nerve exit the pelvis via the
greater sciatic foramen
The superior and inferior gluteal arteries and veins and the internal pudendal artery and vein exit the pelvis via the
greater sciatic foramen
The obturator internus muscle exits the pelvis via the
lesser sciatic foramen
The 4 structures that enter the perineum through the lesser sciatic foramen
nerve to obturator internus, pudendal nerve, and internal pudendal artery and vein
The gluteus medius, gluteus minimus, and tensor fascia latae are innervated by the
Superior gluteal nerve (L5-S1)
The gluteus maximus is innervated by the
Inferior gluteal nerve (L5-S2)
The obturator internus and superior gemellus are innervated by the
Nerve to obterator internus (L5-S1)
The quadratus femoris and inferior gemellus are innervated by the
Nerve to quadratus femoris (L5-S1)
The sciatic nerve branches into the ___ and ___ nerves
tibial and common fibular
The sciatic nerve is made up by the joining of the ____ and the anterior rami of _____
lumbosacral trunk and anterior rami of S1-S3
The nerve that is a large branch medial to the sciatic nerve is the
posterior cutaneous nerve of the thigh
The common fibular nerve usually branches into the ___ nerve
lateral sural
The tibial nerve usually branches into the ___ nerve
medial sural
The 4 nerves that pass through the popliteal fossa are
tibial nerve, common fibular nerve, lateral sural nerve, and medial sural nerve
The internal iliac artery (and veins) divide into ___ and ___
anterior and posterior divisions
The branch off of the anterior division of internal iliac is the
internal pudendal artery/v
The branch off of the posterior division of interal iliac is the
superior gluteal artery/v
Supplies superior gluteal region
superior gluteal artery
Supplies inferior gluteal region
inferior gluteal artery
Supplies external genitalia and perineum
internal pudendal artery
The inferior gluteal a/v can branch off of either the
anterior or posterior division of internal iliac
The perforating arteries supply the
posterior thigh
The perforating arteries are branches off of the
deep femoral artery of the thigh
The continuation of the femoral artery after the adductor hiatus is the
popliteal artery
The ____ supplies the knee, leg, and foot
popliteal artery
The adductor hiatus is located within the
adductor magnus muscle
The hamstring part of adductor magnus, long head of biceps femoris, semimembranosus, semitendinosus, muscles of posterior compartment of thigh, muscles of sole of foot are innervated by
tibial nerve (L4-S3)
The cutaneous sensory of skin of posterior leg and lateral foot is the ___ nerve
medial sural nerve (S1-S2)
The cutaneous sensory of skin of sole of foot is from ___ and ___ nerves
medial (L4-L5) and lateral (S1-S2) plantar nerves
The cutaneous sensory of skin of heel is from ___ n
Medial calcaneal branch (S1-S2)
The ____ innervates the short head of the biceps femoris
common fibular nerve (L4-S2)
The common fibular nerve branches into the ____, ____, and ____
lateral sural nerve (S1-S2), superficial fibular nerve (L4-S1), and deep fibular nerve (L4-S1)
The cutaneous sensory to skin of lateral leg is by the
lateral sural nerve (S1-S2)
The cutaneous sensory to skin of dorsum of foot as well as the fibularis longus and brevis muscles is by the
superficial fibular nerve (L4-S1)
The cutaneous sensory to 1st interdigital cleft, as well as the tibalias anterior, EDL, EHL, EDB, EHB, and fibularis tertius muscles, and the muscles of dorsum of foot are by
deep fibular nerve (L4-S1)
