What do the nerves carry to the muscles?
Electrical impulses telling them to contract or relax.
Does the nervous system transmit information that tells your muscle and otherinternal organs how to react?
The nervous system does not tell muscles how to react. The nerves transmit electrical pulses that make muscles contract. Different nerves attached to different muscles strands control how a muscle reacts. For example, nerves going to some arm muscles when they contract may make your elbow bend. Nerves going to a different set of muscles when made to contract may make your arm straighten out at the elbow. Using all muscles in that area allows you to maintain a bent elbow in a specific position.
What do you need for a limb to move?
For a limb to move, you need muscles, nerves, and a signal from the brain. The brain sends signals through nerves to the muscles, which contract and allow the limb to move.
What are muscles needed for in the human body?
The muscles contract to move parts of the body
If your brain tells your leg muscles to contract what carries the message to the leg muscle?
the nerves and the nervous system
How do muscles get signals from the brain?
Brain sends signal through spinal cord to nerves. Nerves contract which muscle to move and sends a message back to the brain. BOOM! Movement.
What type of nerve stimulates muscle cells to contract?
Somatic type of nerves stimulate the muscle cells to contract.
What action should muscles do to enable the bones to perform or move?
Bones do not move. Nerves are what causes muscles to move. Nerves are connected to the brain. When you attempt to move any body part, your brain instantaneously sends a message to the specific nerves needed to make that body part move. Which makes the muscles flex resulting in movement.

What feeds your muscles so that they can contract?
Your body produces a source of energy from food. It is called ATP. This is what your muscles use to contract. The signals are sent through a simple structure. The electronic signals from your brain travel through a gap in between your muscle and your nerves.
What happens during isokinetic exercise Muscles contract at a constant rate. Muscles contract and relax to move a joint. Muscles do not contract at all. Muscles contract with very little body movement.?
Muscles contract and relax to move a joint. ... Muscles contract at a constant rate. Muscles contract and relax to move a joint.
What tells muscles when to contract?
Muscles contract in response to signals from the nervous system. Motor neurons release neurotransmitters that stimulate muscle fibers to generate a contraction. This process is initiated by electrical impulses called action potentials that travel along the nerves to the muscle cells.
