What else can I help you with?
What tissue is made out of cells that can contract and relax connectivemusclenervousskeletal?
Muscles.
What type of nerve stimulates muscle cells to contract?
Somatic type of nerves stimulate the muscle cells to contract.
What do you call the nerve cells that tell muscles to contract?
Motor neurons.
How can the sun walk around the earth?
Using ATP, the cells in the muscles of the sun's legs use actin and myosin to expand and contract, making the muscles themselves contract and move.
The electrical initiation of a heartbeat begins in the chamber wall?
No, the electrical initiation of a heartbeat begins in the sinoatrial (SA) node, often referred to as the heart's natural pacemaker, located in the right atrium of the heart. Cells in the SA node generate electrical impulses that spread through the heart, causing the heart muscles to contract and pump blood.
Do bone cells expand and contract to move the body?
no, the skeleton is a support structure. The muscles expand and contract to create movement in the body.
What is the function of the group of cells in the heart called the pacemaker?
sending out signals to make the heart muscles contract.
What is the function of the group of cells in the heart called pacemaker?
sending out signals to make the heart muscles contract.
The only tissue that is able to contract and shorten in the body?
muscles
What does it mean when muscles contract and how does this process occur in the body?
When muscles contract, they shorten and generate force. This process is controlled by the nervous system, which sends signals to the muscles to release calcium ions. These ions bind to proteins in the muscle cells, causing them to slide past each other and contract. This contraction allows the muscles to produce movement and perform various functions in the body.
Are antigravity muscles in a constant state of contraction?
No, no muscle is. The cells take turns contracting & relaxing. The "anti gravity" muscles only contract when you're standing up.
What it the name of the long cells that can stretch and contract in the body?
The name of the long cells that can stretch and contract in the body are called muscle fibers. These fibers make up our muscles and are responsible for movement and generating force in the body.
