What else can I help you with?
What is cardiac muscle fibers?
Your cardiac muscle is your heart and this is a muscle and it holds itself together with its fibers. Hope that answers it for you :)
Which type of muscle tissue is autorhythmic?
cardiac muscle
What are autorhythmic fibers?
They are fibres which generate AP(action potential) which trigger heart contractions.
What tissue is your heart composed of?
Cardiac Muscle tissue =)
Are cardiac muscle fibers involuntary?
no
Which fibers carry action potential to cause skeletal muscles to contract?
Alpha motor neurons
What arrangement of cardiac muscle fibers make the heart efficient?
Cardiac muscle fibers are arranged in a crisscross pattern, allowing for efficient contraction and relaxation of the heart. This arrangement helps coordinate the pumping action of the heart and ensures effective blood flow throughout the body.
What is a T-tubule?
A T-tubule is a small, tube-like invagination of the cell membrane in muscle cells, particularly in cardiac and skeletal muscle. T-tubules help to transmit action potentials quickly into the cell interior, allowing for synchronous contraction of muscle fibers.
What carries cardiac impulses to the myocardium?
Cardiac impulses are carried to the myocardium via specialized muscle cells called Purkinje fibers. These fibers are part of the cardiac conduction system and help to transmit electrical signals rapidly and efficiently throughout the heart muscle.
Fibers of the cardiac conduction system are what kind of specalized tissue?
Muscle ( cardiac Muscle)
What is the name of the fibers that carry cardiac impulses from the interventricular septum into the myocardium?
Purkinje fibers
What is unusual about cardiac muscle?
The muscle has unique features that are only in the heart. These muscles are involuntary striated muscle which are only found in the wall of the heart. This is specialised muscle that can contract, Cardiac muscle, like other muscles, can contract, but it can also carry an action potential (i.e. conduct electricity), like the neurons that constitute nerves. Furthermore, some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity.
