What artery wall contains many smooth muscle cells?
The walls of all the arteries are made up of smooth muscle cells.
Can the heart contain smooth muscle?
No, they are not. Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart.This is a specialized muscle that, while similar in some fundamental ways to smooth muscle and skeletal muscle, has a unique structure and with an ability not possessed by muscle tissue elsewhere in the body. Cardiac muscle, like other muscles, can contract, but some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity. Meaning that some of the cells can beat on their own without any nerve stimulation.
What is cardiac muscle?
Cardiac muscle is a type of highly oxidative (using molecular oxygen to generate energy) involuntary striated muscle found in the walls of the heart, specifically the myocardium. Cardiac muscle cells are known as cardiac myocytes. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle. The cells that comprise cardiac muscle are sometimes seen as intermediate between these two other types in terms of appearance, structure, metabolism, excitation-coupling and mechanism of contraction. Cardiac muscle shares similarities with skeletal muscle with regard to its striated appearance and contraction, with both differing significantly from smooth muscle cells. Coordinated contraction of cardiac muscle cells in the heart propel blood from the atria and ventricles to the blood vessels of the circulatory system. Cardiac muscle cells, like all tissues in the body, rely on an ample blood supply to deliver oxygen and nutrients and to remove waste products such as carbon dioxide. The coronary arteries fulfill this function
What kind of tissue is the heart made up of?
Cardiac muscle fibers.
How is the structure of arterioles different from that of arteries?
The wall of the arterioles contain less elastic fibers but more smooth muscle cells than that of the aorta and arteries.
Which type of muscles contain spindle shaped cells?
Skeletal muscle tissue has cylindrical cells. Due to the cells in the skeletal muscle, the muscle can now allow movement to the bones in the body.
Is smooth muscle cells voluntary?
no, skeletal muscle cells are
How are smooth muscle cells similar to skeletal fibers?
Smooth muscle cells are similar to skeletal muscle cells due to the actin-tropomyosin interactions. These interactions "tell" the muscle when to contract.
Which of these cells are likely to have multiple nuclei skeletal muscle cardiac muscle smooth muscle or neuron?
skeletal smooth muscle neuron
What muscle tissue spindle-shape cells?
Smooth Muscle
Do smooth muscles have branched cells?
No, cardiac muscle cells are branched but skeletal muscle cells are linear and do not branch
Do smooth muscle cells posses central nuclei but lack striations?
Smooth muscle is not striated, hence the name smooth muscle.nonotcardiac muscle
Where are spindle cells located?
smooth muscle
What is of the three kinds of muscle cells?
smooth
What artery wall contains many smooth muscle cells?
The walls of all the arteries are made up of smooth muscle cells.
What are 3 of the many types of cells which comprise the cardiovascular system?
Cardiac muscle cells, smooth muscle cells, and endothelial cells.
What is the general shape of smooth muscle cells and plant fibers?
Smooth muscle cells are long, spindle-shaped cells with a central nucleus. Plant fibers are elongated cells with thick cell walls that can be either round or polygonal in shape, depending on the plant species.
