What are the key differences in the structure and function between smooth muscle and cardiac muscle?
Smooth muscle is found in the walls of internal organs and blood vessels, while cardiac muscle is found in the heart. Smooth muscle is involuntary and under autonomic control, while cardiac muscle is also involuntary but has its own specialized conduction system. Smooth muscle cells are spindle-shaped and have a single nucleus, while cardiac muscle cells are branched and have one or two nuclei. Smooth muscle contracts slowly and rhythmically, while cardiac muscle contracts quickly and continuously.
Which muscle tissue skeletal smooth or cardiac changes internal volume of an organ as it contracts?
"When smooth muscle contracts, the cavity of an organ alternately becomes smaller or enlarges so that substances are propelled through the organ along a specific pathway"Smooth muscle
What are the key differences in the structure and function of smooth muscle compared to cardiac muscle?
Smooth muscle and cardiac muscle have different structures and functions. Smooth muscle is found in organs like the intestines and blood vessels, and is involuntary. It has a spindle-shaped structure and contracts slowly and rhythmically. On the other hand, cardiac muscle is found in the heart and is also involuntary. It has a branching structure and contracts quickly and continuously to pump blood throughout the body.
What are contract muscles?
Smooth Muscle contractions are regulated by calcium ions. The smooth muscle differs from skeletal muscle in that its contracts from all sides.
When the smooth muscle of the artery contracts the action is called?
Vasoconstriction!
What is the action called when the smooth muscle of the artery contracts?
Vasoconstriction!
Does the smooth muscle tire quickly?
skeletal muscle
What is a smooth muscle that contracts or relaxes to change the volume of the chest?
The Diaphragm.
How does smooth muscle tire quickly?
Sex
What smooth muscle contracts produce when an artery or arteriole is damaged?
a vascular spasm
What kind of tissue contracts?
Muscle tissue is responsible for contraction in the body. There are three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscle is attached to bones and helps with movement, cardiac muscle is found in the heart and helps pump blood, and smooth muscle is found in organs and blood vessels to help with various functions.
The inside of your stomach is lined with?
