1-Inversion involves the movement of the sole towards the median plane – so that the sole faces in a medial direction. 2-Eversion involves the movement of the sole away from the median plane – so that the sole faces in a lateral direction.
37
What is Opposition and Reposition
A pair of movements that are limited to humans and some great apes, these terms apply to the additional movements that the hand and thumb can perform in these species. 1-Opposition brings the thumb and little finger together. 2-Reposition is a movement that moves the thumb and the little finger away from each other, effectively reversing opposition.
38
What is protraction and retraction
Protraction describes the anterolateral movement of the scapula on the thoracic wall that allows the shoulder to move anteriorly. In practice, this is the movement of ‘reaching out’ to something. Retraction refers to the posteromedial movement of the scapula on the thoracic wall, which causes the shoulder region to move posteriorly i.e. picking something up.

The 2 main hip flexors are : ``` 1 psoas (illopsoas) 2 rectus femoris (quadricep muscle that begins at the front of the hip joint) ```
63
What is the psoas
The psoas is a deep-seated core muscle connecting the lumbar vertebrae to the femur. The psoas major is the biggest and strongest player in a group of muscles called the hip flexors:
64
What area of the hip does the mula and uddiyana lock
psoas muscle
65
When the psoas muscle is shortened what happens
1 pulls femur into the socket (limit mobility of hip) and tightens lateral rotators 2 causes abdominal muscles to tighten 3 causes compression of the lumbar spine
66
What is the Rectus Femoris
A muscle in the quadriceps, the rectus femoris muscle is attached to the hip and helps to extend or raise the knee. This muscle is also used to flex the thigh. The rectus femoris is the only muscle that can flex the hip.

What are the hip extensors
Gluteus maximus The gluteus maximus (also known collectively with the gluteus medius and minimus, as the gluteal muscles ("glutes") is the main extensor muscle of the hip.
68
What are the hamstrings
The hamstrings are a group of muscles and their tendons at the rear of the upper leg. They include the 1 biceps femoris 2 semitendinosus 3 semimembranosus. The hamstrings flex the knee joint, adduct the leg, and extend the thigh to the backside of the body. They are used in walking and running.
69
What are the abductors of the hips
The hip abductor muscles include the 1 gluteus medius, 2 gluteus minimus, 4 tensor fasciae latae (TFL). They not only move the leg away from the body, they also help rotate the leg at the hip joint.
70
What are the adductors of the hips
The muscles in the medial compartment of the thigh are collectively known as the hip adductors. Used in the tree pose
71
What are the internal rotators
Internal rotators: Gluteus medius Gluteus minimus TFL (tensor fascia lata)
72
What are the external rotators
6 muscles 1 Piriformis, These muscles are short thick and strong Responsible for the stability of the pelvis ``` 2 gemellus superior, 3 obturator internus, 4 gemellus inferior, 5 quadratus femoris 6 obturator externus. ```
73
What is the piriformis
A muscle that runs from the sacrum to the femur A muscle in the gluteal region of the lower limbs. It is one of the six muscles in the lateral rotator group.
74
c
Piriformis syndrome is a condition in which the piriformis muscle, located in the buttock region, spasms and causes buttock pain. The piriformis muscle can also irritate the nearby sciatic nerve and cause pain, numbness and tingling along the back of the leg and into the foot (similar to sciatic pain).
