Deffense [45]

According to model 3. During the child birth the stimulus is baby pushes against the cervix and the response would be hypothalamus oxytocin to male uterine walls contract.

Answer:

-The three main types of muscle include skeletal, smooth and cardiac.

- Skeletal muscle – the specialised tissue that is attached to bones and allows movement. ...

Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. ...

Cardiac muscle – the muscle specific to the heart.

-Skeletal muscles are attached to the skeleton by tough connective tissues called tendons

-Many skeletal muscles are attached to the ends of bones that meet at a joint. The muscles span the joint and connect the bones. When the muscles contract, they pull on the bones, causing them to move.

-They are lightweight yet strong and hard, and serve multiple functions.

-The joints help attach bones to one another to provide flexibility & allow the muscles to help give the bones a way to move.

- The nervous system helps all the parts of the body to communicate with each other.

-Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body.

-homeostasis?

Receptors in muscles provide the brain with information about body position and movement. The brain controls the contraction of skeletal muscle. The nervous system regulates the speed at which food moves through the digestive tract.
