Nerve impulses that originate in the central nervous system cause muscles to contract. Muscle fiber generates tension during the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten, or remain the same.

Agonist
What is a muscle that causes a desired action and is often made more efficient with the assistance of synergists?
The answer is AGONIST.
What is the action of the muscles that causes air to come into the lungs?
The action is the flattening of your diaphragm, or the muscle that helps your lungs inhale and exhale.
What and where are sarcomeres?
These are found in muscle cells. The action causes contractions. They cause a sliding or shortening movement.
What part of the muscle cell membrane contain acetylcholine receptors?
When the Ach binds to receptor sites on the muscle cell membrane it causes channels to open and allows Na+ to move into the cell which then causes an action potential.
What are the complex muscle movements?
Complex muscle movements is the ability for the muscles to move to the desired directions.
What is the involuntary muscle action of alimentary canal?
The involuntary muscle action of the alimentary canal is called peristalsis. It uses this muscle action to move food through.
What muscle that counteracts the action of another muscle?
antagonist muscle
What describes the action of the digastric muscle?
THe action of the digastric muscle is to depress the mandible or evaluate the larynx
Why do you get muscle spasms?
Muscle spasm are caused by due to hyper or hypo stimulation of the peripheral nerves which in turn decrease or increase the action.
What is the muscle that causes parts of the body to bend?
A flexor is a muscle that causes a joint to bend. In contrast, an extension is a muscle that straightens a joint.
What causes an action potential when it binds the motor end plate?
Chemically gated sodium channels open up when neurotransmitters bind to receptors in the motor end plate. This causes an action potential along a muscle membrane or nerve cell.
