What are the Deep 6 muscles?
|
PiriformisObturator internusObturator externusGemellus superiorGemellus inferiorQuatratus femoris
|
|
What do the Deep 6 muscles do and where are they located?
|
They are located from various spots on the pelvis to the trochanter of the femurThey are the TURNOUT muscles: all of them assist in hip external rotation and stabilization of the hip joint
|
|
What are the adductor muscles?
|
Adductor longusAdductor brevisAdductor magnus
|
|
Where are the adductor muscles and what do they do?
|
Run from the pubis to the linea aspera of the femur- run diagonally on the medial thighThey are responsible for hip adduction and hip flexion in the lower ranges
|
|
Where is the Tensor fasciae latae (TFL) and what does it do?
|
From the ilium to the tibia via the iliotibial bandActions: hip abduction, hip flexion, and hip internal rotation
|
|
Where is the Gracilis and what does it do?
|
It runs from the pubis to the medial surface of the upper tibiaActions: hip adduction, hip flexion, knee flexion
|
|
Where is the Pectineus and what does it do?
|
"the groin muscle" Superior ramus of the pubis to the upper shaft of the femur (close to the linea aspera)Actions: hip adduction, hip flexion
|
|
What is the linea aspera?
|
The linea aspera is a roughened ridge on the posterior femur that is an important insertion point for the adductors
|
|
What are the three muscles of core support and what is the muscle group called? What are their actions?
|
The Iliopsoas- the strongest of the hip flexors and are important for standing, walking, and runningPsoas major- flexing the leg and bending the trunk forwardPsoas minor- same, not present in half of the populationIliacus- flexing the leg or bending the truck forward
|
|
Where is the iliopsoas group?
|
Psoas major: Originate along the lateral surfaces of T12 and L1-4, crosses the hip joint and inserts on the lesser trochanter
Psoas minor: Originates at the transverse processes of L1-5 and inserts at the iliopectineal arch, a thickened band of fascia Iliacus: Originates in the iliac fossa, joins the psoas major and inserts on the lesser trochanter |
|
What is the 6 pack called, and what does it do?
|
The rectus abdominus, separated in the middle by the linea albaOriginates at the pubic crestFlexion of the vertebral column, assists in respiration, support, and protection
|
|
Where is the transverse abdominus, and what does it do?
|
The deepest layer that girdles you, does the same protection and assists in respiration (and also when you cough or throw up)
|
|
What is the layer above the transversus and what does it do?
|
The internal oblique- runs on a diagonalbilateral flexion, compression, forced respiration, and same side (ipsilateral) rotation
|
|
Where are the external obliques and what do they do?
|
The most superficial muscles on the side, on a downward diagonalcontralateral rotation, bilateral flexion, compression of abdomen
|
|
Where is the sartorius and what does it do?How many joints does it cross?
|
The longest muscle in the human body: From the ASIS to the medial surface of the upper tibia- long and thin that runs across the leg and down the length of the thighhip flexion, hip abduction, hip external rotation
Crosses 2 joints |
