Gluteal muscles and hip movements Flashcards
What is the Action and innervation of the gluteus maximus?
hip extesnion
innervation- inferiro gluteal nerev
describe the Action and innervation of the gluteus medius (what is it dee to)
Action- hip abduction (and medially rotation)
innervation superiro gluteal nerev
what is the role of gluteus minimus- describe its innervation
deepest gluteus muscle and the smalles
action- hip abduction
innervation- superiror gluteal nerev
what are the five rotator muscles in the gluteal region?
that run tranvers across the joint making them rotators?
superior to inferiror
Piriformis (largest pear shape- can see sicatic nerev run immedioately inferiror)
superiror gemellus
obtruator internus
inferiror gemellus
quadratus femoris (square shaped)
Label this
- piriformis
- superiro gemellus
- obturator internus (forms membrane of obturatro formaen
- inferiro gemellus
- quadratro femoris
describe the action and innervation of pirformis?
hip rotator
imnnervation- nerev to pirformis (from lumbo sacral plexus()
obturatro inernus
action and innervation
Action- hip rotation
innervation- nerve to obtruator internus
Describe the action and nerev supply to the Gemelli (superiro and inferiro)
Gemellin = twins
action- hip rotation
superirro- Nerev to obturator internus
Inferiro- nerev to quadratus femoris
Describe the action and innervation of Quadratus femoris
Action- hip rotation
innervation- nerve to quadratus femopris
The anteriro thigh muscle are involved in what moveemtn?
Flexion
Iliopsoas
quadriceps (rectus femoris)
satrotisus
what is this muscles name and action?
Iliopsosa
made up of psoas major and illiacus muscle
invovled in hip flexion
wwhich quadriceps muscle is invovled in hip felxion
Hip flexion- Rectus femoris only!
what muscle has a role in hip flexion and laterally rotating the thigh?
Sarortorius
hip flexion and laterally roation - inserts onto the proximal end of the tibia
what muscles in the posteriro thigh are involved in Extension of the thigh?
innervation?
Hamstrings!
biceps femoris, seminteinosus, semimembranossu
sciatic nerve
What muscles are invovled in adduction of the thigh?
the medial thigh adductors
Innervation- obturator
PEcitnius musclke
