Question

What term is used for the muscles which draw a bone away from the body midline?

Answer 1

Hint: Muscles are the organ for movement. They are attached to the bones which help in their movement. It has the skeletal muscle tissues, blood vessels, nerves and tendons. The muscles which help in drawing bone away from the body midline are present in hips and thighs.

Complete answer:
The muscular system are the organs in our body which helps in the movement of the human body. There are 700 different types of muscles present in our body which facilitate the movement. The muscles act on the synovial joint and facilitates different kinds of movement like flexion and extension (forward and backward movement), pronation, elevation and depression (up and down movement of jaws and shoulder), protraction and retraction (forward and backward) etc.

The muscles which help in drawing the bones away from the midline are called the abductor muscles. These muscles are present in the hip and thigh. This muscle helps in rotating the leg along the hip joint. These muscles are important for maintaining a stable posture while walking or standing on a single leg. The gluteus medius, gluteus minimus, and tensor fasciae latae (TFL) are the type of hip abductor muscles. If these muscles are weak, it can lead to pain and unstable posture.

Note: The movement often paired with abduction is the adduction. It means the movement of the body towards the midline. These two movements facilitate the side-wise movements. This is usually seen when moving the arms during jumping jacks. The adduction of the hips is caused by pectineus, adductor longus, adductor brevis, adductor magnus, and gracilis.
