Select the options that help explain how the nervous system and the skeletal system work together to help an organism move. Select all that apply.
|
|
Nerve signals originating in the cerebrum of the brain are sent to the limb that needs to be moved.
|
|
|
After receiving nerve signals, contraction of the muscles in a limb move it by exerting force on the skeleton.
|
|
|
Signals starting in the skeletal cells are sent to the brain causing contraction of muscles.
|
|
|
Nerves attached to the muscles in the moving limb detect a loss of balance and send a signal to the cerebellum of the brain to help correct the coordination.

Explanation:
Detailed explanation-1: -Your nervous system (brain and nerves) sends a message to activate your skeletal (voluntary) muscles. Your muscle fibers contract (tense up) in response to the message. When the muscle activates or bunches up, it pulls on the tendon. Tendons attach muscles to bones.
Detailed explanation-2: -How Does the Nervous System Work? The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network.
