Answer:
The muscular system's main function is to allow movement. When muscles contract, they contribute to gross and fine movement.
A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles. Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron.
Muscles provide the tug on the bones needed to bend, straighten, and support joints. Muscles can pull on bones, but they can't push them back to their original position, so the muscles work in pairs of flexors and extensors. ... Muscles get their signals to contract and relax from the brain..
Answer:
The muscular system's main function is to allow movement. When muscles contract, they contribute to gross and fine movement.
Example:
Flexion and extension are usually movements forward and backward from the body, such as nodding the head. ... Extension: increasing the angle between two bones (straightening a bend).
