Is cardiac muscle striated?

There are 3 types of. Muscle, skeletal-compose of our muscle mass attach to the skeleton; smooth-located in the walls of hollow visceral organs except the heart; cardiac or striated. In practice, the term is sometimes used to refer exclusively to cardiac when distinguishing it from smooth muscle. Other dictionaries called striated muscle to skeletal muscle. Good question!

Myocardium. Its function is to rhythmically shorten and then relax so as to provide motive force to pump blood through the vascular system. Read more...

Pump blood. The heart muscle relaxes, and the chamber gets bigger and fills up with blood. The heart muscles squeezes and pumps blood out. (Valved in the heart make sure everything goes forward.) Read more...

What are the functions of cardiac muscle fibers?

See below. The heart is a muscle with very special qualities. The main bulk of heart muscle helps pump blood to the lungs to get oxygen and then pumps that oxygen rich blood to the rest of the body. Then there is a special type of cardiac fibers that helps conduct electrical impulses from two "pacemaker" sites in the heart, the sa and av nodes which allow the heart to keep pumping for your entire life.

Help please? What is the threshold voltage in cardiac muscle?

Depends. It depends on which cardiac muscle tissue. In the SA node, its around -50 mv. In subsidiary pacemakers it can be as much as -90 mv. Read more...

Could there be more than one intercalated disc in a cardiac muscle cell?

No. Intercalated discs allow cardiac cells to join together. They're not really within a cardiac cell. Good luck on your exam or whatever it is that prompted you to ask this question. . Read more...

Can any doc tell me what's the function of your cardiac muscle?

Heart is a muscle. Cardiac muscle contracts and relaxes known as heart beats. This sends blood entering into the heart to flow out into major blood vessels; the thoracic aorta and the main pulmonary artery. Blood from lungs enters heart via pulmonary veins and is pumped into the aorta delivering oxygen to body. Oxygen poor blood from body enters heart via vena cavae and pumped into lungs via pulmonary artery. Read more...

What is the mechanism by which smooth, skelatol and cardiac muscle twitch?

Depolarization. When you apply an electric current to any of the above fibers, you cause depolarization, ion flux, and movement of protein filaments resulting in the characteristic "twitch". If you're really interested, check out: http://www.Youtube.Com/watch?V=fduja8rwntk. Read more...
