What else can I help you with?
The command to contract link is transferred throughout a muscle fiber by?
motor and plates
Is it true Skeletal muscle contraction causes ATP to break down releasing heat that is distributed about the body?
Yes, during skeletal muscle contraction, ATP is broken down to provide the energy needed for muscle fibers to contract. This process generates heat as a byproduct, contributing to thermoregulation in the body. The heat produced is then distributed throughout the body, helping to maintain a stable internal temperature.
The only tissue in youur body that is able to contract or shorten?
Muscle tissue is the only tissue in the body capable of contracting or shortening. This contraction allows muscles to generate force and produce movement throughout the body. There are three types of muscle tissue: skeletal, cardiac, and smooth, each with its own unique properties and functions.
What initiates the contraction of cardiac muscle?
The contraction of cardiac muscle is initiated by electrical signals from the heart's natural pacemaker, the sinoatrial node, which causes the muscle cells to contract in a coordinated manner, pumping blood throughout the body.
What is needed for living muscle to contract?
A living muscle needs oxygen in the blood and muscle elasticity to contract and move.
What type of tisssue is able to contract?
Muscle tissue is the type of tissue that is able to contract. There are three main types of muscle tissue: skeletal muscle, which is under voluntary control and moves bones; cardiac muscle, which makes up the heart and is involuntary; and smooth muscle, found in the walls of hollow organs and also involuntary. These tissues enable movement and various physiological functions throughout the body.
The main structural difference that cardiac muscle have that other two types dont?
Intercalated discs. These are specialized cell junctions which link the cardiac muscle cells electrically and mechanically together. Impulses are distributed immediately and simultaneously so that cardiac muscle cells contract as a single unit.
What kind of muscle cell contract?
Smooth muscle cells contract in response to fluid flow.
What is muscle protein?
it is tiny muscle fibers that contract and expand the muscle
Will the leg muscle contract when it is removed from the body and you pinch it?
No, as the muscle is dead (it doesn't contract like while the muscle is still alive either). However, it will contract if you give it an electrical "jump."
How are the 31 pairs of spinal nerves distributed throughout the human body and what functions do they serve?
The 31 pairs of spinal nerves are distributed throughout the human body, with each pair connected to a specific region of the body. These nerves serve important functions such as transmitting sensory information from the body to the brain and controlling muscle movements.
What tissue's major function is to contract?
The muscle tissue's main function is to contract.
