Question

how to muscle causes action

Answer 1

●When Potential Travels Along the Nerves to the muscles than the muscle causes action.

●The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron.

●When a motor nerve impulse sent by the spinal cord (or brain) reaches the effector organs which are muscles, then the muscles cause action or movement (duch as lifting the hand away from a hot plate.

●Muscular contraction produces an action, or a movement of the appendage.

Answer 2

First of all, thanks for asking this question..

Here is your answer:-

• When a motor nerve impulse sent by the spinal cord (or brain) reaches the effector organs (which are muscles), then the muscles cause action or movement (such as lifting the hand away from a hot plate). We will now describe how muscles are able to move in response to electrical nerve impulses and cause action.

• Muscles are made up of muscle cells. Muscle cells contain special proteins which can change their arrangement when stimulated by electrical impulses, causing the muscle cells to change shape and contract. When the muscle cells contract, the muscles also contract (and become shorter).

• When the muscles contract, they pull on the bones of the body part and make it move.
