What is voluntary muscle?

Voluntary muscles are muscles that are consciously controlled by the brain. They are also known as skeletal muscles, because they are attached to the skeleton. Voluntary muscles are used for movement, such as walking, running, jumping, and talking.

Voluntary muscles are made up of long, cylindrical muscle cells that are multinucleated. This means that each muscle cell contains many nuclei. The muscle cells are arranged in bundles, which are surrounded by a connective tissue sheath. The connective tissue sheath helps to protect the muscle cells and provides a pathway for blood vessels and nerves to reach the muscle cells.

When a nerve impulse reaches a voluntary muscle, it causes the muscle cells to contract. The contraction of the muscle cells pulls on the tendons, which are attached to the bones. This causes the bones to move.

Voluntary muscles are responsible for a wide range of movements, from small movements, such as blinking, to large movements, such as running. They also play a role in maintaining posture and balance.

Voluntary muscles are important for everyday life. They allow us to move around, communicate, and perform other tasks that require movement. Without voluntary muscles, we would not be able to survive.
