16
Q

Psoas major

A

O= lumbar, spine (bodies of all lumbar vertebrae)
I = Lesser trochanter of femur as iliopsoas tendon
A = Flexion of the thigh/trunk, lateral rotation of the thigh, Lateral flexion of the trunk

17
Q

Illacus

A

O= Illiac fossa

I= lesser trochanter as one tendon

A = Hip flexor

18
Q

Medial posterior compartment Adductor Region

A

Adductor Magnus, Adductor longus, Adductor Brevis Pectineus, Gracilis

19
Q

Adductor Magnus

A

O= body of pubic bone
I= Posterior femur linea aspera
A= Thigh flexion, thigh adduction, thigh external rotation
internal rotation

20
Q

adductor longus

A

O=bodyof pubic bone
I= Posterior femur linea aspera
A= Thigh flexion, Thigh adduction, Thigh external rotation

21
Q

Adductor brevis

A

O = body rami of pubic bone
I = Posterior femur linea aspera
A= Hip joint: thigh flexion, thigh adduction, thigh external rotation; pelvis stabilization

22
Q

Pectineus

A

O=Superior pubic ramus
I= linea aspera of femur
A= Thigh flexion, thigh adduction, thigh external rotation, thigh internal rotation

23
Q

Gracilis

A

O = body of pubic bone
I =pes anserinus
A= Thigh flexion, thigh adduction leg flexion, leg internal rotation

24
Q

Gracilis

A

O = body of pubic bone
I = Pes anserinus
A= Thigh flexion, thigh adduction leg flexion, leg internal rotation

25
Gluteal Superficial
Gluteus maximus, Gluteus medius, Gluteus minimus piriformi, Quadratus femoris
26
piriformi
O = Gluteal surface of ilium I = Greater trochanter of the femur A = high external rotation, Thigh abduction (from flexed hip); Stabilizes head of femur in acetabulum
27
Quadratus femoris
O= Ischial tuberosity I = Intertrochanteric crest of femur A = thigh external rotation; stabilizes head of femur in acetabulum
28
The tensor fasciae latae
O = Outer lip of anterior iliac crest I = Lateral condyle of tibia A= Thigh internal rotation, (Weak abduction); Knee joint: Leg external rotation, (Weak leg flexion/ extension); Stabilizes hip & knee joints
29
muscles for Flexion of hip joint
Psoas major, iliacus and rectus femoris; assisted by pectineus, tensor fasciae latae and sartorius
30
muscles for extension of hip joint
Gluteus maximus, biceps femoris, semitendinosus, semimembranosus and adductor magnus
31
muscles for adduction of hip joint
Adductors longus, brevis and magnus, gracilis; assisted by pectineus, quadratus femoris and the inferior fibres of gluteus maximus
32
muscles for abduction of hip joint
Glutei medius and minimus; assisted by tensor fasciae latae, piriformis and sartorius
33
muscles for external rotation of hip joint
Gluteus maximus, obturator internus, superior and inferior gemelli, quadratus femoris, piriformis; assisted by obturator externus and sartorius Mnemonic
34
muscles for internal rotation of hip joint
Glutei minimus and medius; assisted by tensor fasciae latae and most adductor muscles
35
the greater trochanter insertion for
gluteus medius, gluteus minimus, piriformis, obturator externus, and obturator internus.
36
the lesser trochanter insertion for
psoas major muscle and the iliacus muscle
