Question

Why are at least two muscles needed to move a bone at a joint in one direction?

Answer 1

Explanation:

Generally, two skeletal muscles are joined to one bone, so that when one muscle contracts in one direction for enabling the bone to move in that specific direction; the other muscle becomes relaxed to facilitate the movement of the bone.

Answer 2

Answer:

ANSWER :-

☆ 2 muscles are required to hold the bone so that it can easily move in one direction.

☆ From our head to our toes, bones provide support for our bodies and help form our shape. The skull protects the brain and forms the shape of our face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column.

☆ Bones don’t work alone ==> they need help from the muscles and joints. Muscles pull on the joints, allowing us to move. They also help your body perform other functions so you can grow and remain strong, such as chewing food and then moving it through the digestive system.

• The human body has more than 650 muscles, which make up half of a person’s body weight.

• They are connected to bones by tough, cord-like tissues called tendons, which allow the muscles to pull on bones
