Muscles.
Somatic type of nerves stimulate the muscle cells to contract.
Motor neurons.
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.
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.
no, the skeleton is a support structure. The muscles expand and contract to create movement in the body.
sending out signals to make the heart muscles contract.
sending out signals to make the heart muscles contract.
muscles
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.
The cells that contract to cause movement in the eye are the extraocular muscles. These muscles, which include six distinct groups (superior rectus, inferior rectus, medial rectus, lateral rectus, superior oblique, and inferior oblique), are responsible for controlling the eye's orientation and movement. When these muscles contract, they enable the eye to move in various directions, allowing for coordinated vision and tracking of objects.
No, no muscle is. The cells take turns contracting & relaxing. The "anti gravity" muscles only contract when you're standing up.
