Cardiac muscle is a type of involuntary striated muscle found in the walls of the heart, particularly the myocardium. Cardiac muscle cells are identified as cardiac myocytes or cardiomyocytes. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle. Cardiac muscle, different from skeletal muscle, is composed of separate cellular elements. A cardiac muscle cell has a large nucleus and numerous mitochondria. The elevated concentration of mitochondria reveals the huge energy burden that predominant the heart. Contractile proteins of actin and myosin myofilaments are in the cytoplasm. They form bands of varying density. The heart produces regular electrical impulses causing the muscle myofibrils to glide above one another and squeeze the cardiac muscle.


Some cardiac cells are self-excitable, contracting devoid of any signal from the nervous system. Each of these cells have their own inherent contraction rhythm. A section of the human heart called the sinoatrial node, or pacemaker, sets the rate and timing that all cardiac muscle cells contract. The SA node generates electrical impulses, from the SA node spreading rapidly through the walls of the artria, causing both artria to contract in unison. The impulses also pass to another section of specialized cardiac muscle tissue, a convey point called the atrioventricular node AV bundle or artioventricular bundle or Bundle or His. This collection of heart muscle cells are also specialized for electrical conduction that transmits the electrical impulses from the AV node to the point of the apex of the fascicular branches. The fascicular branches then lead to the Purkinje fibers then conduct the signals to the apex of the heart along and throughout the ventricular walls. The Purkinje fibers form conducting pathways called bundle branches.

What tissue is specialized to conduct electrical signals from one structure in the body to another structure?

Nerve tissue is specialized to conduct electrical signals (impulses) from one part of the body to another. Nerve cells, or neurons, have unique properties that allow them to transmit these signals through a combination of electrical and chemical processes.


Do epithelial tissue conduct impulses?

No, epithelial tissue does not conduct impulses. Epithelial tissue functions primarily in protection, secretion, absorption, and sensation. Nerve cells, or neurons, are responsible for conducting impulses in the body.


Which type of tissue is specialized for conduction of impulses?

Nervous tissue is specialized for the conduction of impulses, specifically through neurons which transmit electrical signals throughout the body. This tissue is critical for communication within the body and enables functions such as movement, sensation, and cognitive processes.


Which tissue type conducts impulses?

Nerve cells, neurons, are designed to conduct electrical impulses, passing messages between the nerves and other tissues. For example, one impulse is sent to the brain signaling pain when you burn your hand and than another message telling your hand to move off the stove.


What are any types of tissues?

Epithelial tissue: covers and protects surfaces. Connective tissue: supports and connects different structures. Muscle tissue: allows for movement. Nervous tissue: carries electrical impulses for communication.

Does muscle tissue conduct nerve impulses from one neuron to another and coordinates body activity?

Muscle tissue cannot conduct nerve impulses from one neuron to the other. Moreover, skeletal muscle tissue cannot even pass impulses between themselves and they should be stimulated by single branches of neurons. However, cardiac muscle cells has the unique ability to conduct impulses between themselves through gap junctions.
