Can you contract your smooth and cardiac muscles on purpose?
Smooth Muscles can, but Cardiac Muscles can not.
What happens if cardiac muscles do not contract?
You would get a heart attack otherwise known as a cardiac arrest.
How is cardiac muscles similar to smooth muscles?
they both contract and relax to cause movement and both are uninucleated.
What happen when cardiac muscle contract?
ambot lang
What happen to the shape of the earthworm when the circular muscles contract?
When the circular muscles of an earthworm contract, the segments of its body become thinner and longer, causing the earthworm to elongate and appear stretched out.
What is the function of a cardiac cell?
Cardiac cells are muscle cells that make up the heart (cardiac tissues). When the muscles contract, they force blood out of the ventricles of the heart.
Which type of muscles causes the heart to contract and relax?
auto-rhythmic cardiac muscle
The heart is made up of cardiac muscles what happend when these muscles contract?
Yes, the heart is made of muscles, however, these muscles do not all contract at one time. They contract in synchrony and when they contract they squeeze the chamber they surround such are the atria or ventricle and blood is pushed out of the chamber.
What type of muscles are the cardiac muscles?
cardiac muscles
What would happen if your whole body was made of cardiac muscle?
I think that what you mean to ask is, what would happen if all your muscles were cardiac muscles. Obviously, if your whole body was made of cardiac muscle it would die, since it would have no lungs, no brain, no digestive system, no skin, etc. Muscles do not a body make. But if all your muscles were cardiac muscles, chances are that would be workable. I know of no reason why cardiac muscle could not perform other muscular functions than pumping blood.
Do cardiac muscles work in pairs?
No, cardiac muscles do not work in pairs. They are arranged in a network within the heart and work together in a coordinated manner to contract and pump blood throughout the body. The contraction of cardiac muscles is regulated by electrical signals from the heart's pacemaker cells.
What does acetycholine do to muscles?
Acetylcholine acts to excite skeletal muscles, allowing for the muscle to contract. It also serves to allow contractions in the smooth muscles, while slowing down the cardiac muscles
