What type of muscle is located in the walls of the digestive organs?
Longitudinal and circular muscles. These are known as antagonistic muscles, meaning that one relaxes whilst the other contracts.
Organ that relaxes and contracts?
Smooth muscles
What is the name for the rhythmic smooth muscle?
The rhythmic smooth muscle is called the visceral smooth muscle. It is found in the walls of organs such as the intestines, uterus, and blood vessels, and it contracts and relaxes spontaneously to generate rhythmic movements.
What is the type of muscle that squeezes and relaxes without stopping?
the smooth muscle
How do skeletal muscles work as a pair to bend and straighten the arm at the elbow?
When you bend your elbow, the biceps muscle contracts. At the same time the antagonist muscle, that is the triceps muscle relaxes in synchronized manner. Vise verse action take place, when you straighten the arm at the elbow. Triceps contracts and biceps relaxes.
Muscle that is NOT striped and is involuntary is?
Smooth muscle is the type of muscle that is not striped (striated) and is under involuntary control. It is found in various organs such as the digestive system, blood vessels, and the respiratory system. Smooth muscle contracts and relaxes in response to various stimuli without conscious effort.
Smooth muscle that controls light intensity?
The smooth muscle in the iris of the eye controls the size of the pupil, which regulates the amount of light entering the eye. When this muscle contracts, the pupil constricts, reducing the amount of light that enters the eye, and when it relaxes, the pupil dilates to allow more light in.
Pumped back into the smooth ER when muscle relaxes?
Calcium ions
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 is the name of the substance that is pumped back into the smooth er when muscle relaxes?
ATP
What does the triceps muscle do when the bicep contracts and gets shorter?
When the biceps muscle contracts and shortens, it primarily flexes the elbow, bringing the forearm closer to the upper arm. In this action, the triceps muscle relaxes and lengthens to allow for smooth movement, acting as an antagonist to the biceps. This coordinated action helps maintain balance and control during arm movements.
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.
