Cardiac muscle

The human body consist of 680 skeletal muscles. The name of a muscle can distinguish its location, action, shape, and function. One such example is the biceps brachii, which is commonly referred to as biceps. As the name implies, this is a two-headed muscle. The term biceps brachii is a Latin phrase that means, "two-headed muscle of the arm." This is references to the fact that the muscle consists of two bundles of muscles. Each of these bundles has its own origin and share a common insertion point

shape and size of cells Cardiac muscle is involuntary because the heart works all the time and never gets fatigued unlike skeletal muscle which is voluntary because it is used for body movement such as sitting, walking and lifting. Skeletal muscle differs from cardiac muscle as it is multinucleated compared with cardiac muscle that is uninucleated. This means skeletal muscle have more than one nucleus and cardiac muscle has one nucleus in the muscle cells. Also, cardiac muscle has semi-spindle shape-like

of blood. Cardiac muscle cells are called Cardiomyocytes. These cells are equipped with specialized organelles such as myofibrils, mitochondria, the sarcoplasmic reticulum for storage and release of calcium and the sarcolemma which is a membrane that encloses each muscle cell. Cardiomyocytes have a tremendous amount of mitochondria present inside the cell compared to many other cells, this gives the cardiomyocyte the ability to be highly resistant to fatigue. Whereas skeletal muscle cells can fatigue

Structure The cardiac muscle is only found in the heart. This muscle had one nucleus and is an involuntary striated muscle. Cardiac muscle also contains intercalated disc, which acts as a junction between the two muscle cells in order to communicate. Also, the cell contains no motor nerve terminals. The extracellular calcium ions and the cells of the heart act as a stimulus allowing it to contract via electrical impulse. The cardiomyocytes/ myocardiocyteal muscle cells and the one nucleus makes

1. What is a membrane potential? Why is it so important in nerves and muscles? Membrane potential is the way in which nerve and muscle tissue respond to rapidly changing external stimuli. Is it important to nerves and muscles because it allows them to react and sense changes. 2. What are neuroglia and what is their function? Neuroglia protect and assist neurons 3. Name and describe the various structures found in a neuron. The various structures of the neuron are the soma, axon, and dendrites

answer is cardiac muscle. This is what really makes the body work. The cardiac muscle is located on the inner walls of the heart. It helps the heart pump blood to the rest of the body, without it the body would die, that is why it is the imperative for a person's health.. The cardiac muscle is important because it is what keeps that person alive.“The major function of cardiac muscle cells is to contract so as to enable the heart to pump blood to all the parts of the body.” The cardiac muscle is vital

Cardiac muscle tissue is a specialised muscle tissue that is only found in the heart. It is an involuntary muscle as it doesn’t response to the needs of your body, even though it’s controlled by the brain. In contrast, to the skeletal muscle which is a voluntary muscle as the brain controls the movement but you are aware of the movements. The main function of the cardiac muscle is to pump blood around the body and essentially keep us alive. Whereas, the skeletal muscle has many basic functions such

INTRODUCTION The cardiac muscle, more commonly known as the heart muscle, is quite different from the more familiar know skeletal muscle. Unlike skeletal muscle, cardiac muscle is able to conduct its own electrical impulses allowing it to contract and relax spontaneously without being told to by the brain or any other organ (Marieb, Mitchell, p. 512). This is due to the constant leakage of sodium ions into the mainly potassium filled cells which then eventually lead to action potentials causing

Comparing and contrasting cardiac Muscle tissue (figure a) and brain tissue (figure d) Commonalities in the structures and functions of muscle tissue and brain tissue In cardiac muscle, a single nucleus is located in the middle of each fibre. The brain tissue also has a nucleus which is located in the middle of cell body. The cardiac muscle and brain tissue don’t have the exact same function. The cardiac muscle and the brain tissue don’t work together because the cardiac muscle doesn’t takes any instructions

The cardiac muscle cell embraces most of the hearts mass. It plays the most important significant role in the heart, pumping blood through the heart and into the body. It’s a long-life source, which never stops pumping. It’s continuous and persists an entire lifetime without unfluctuating or skipping a beat. The cardiac muscle is strong and has a long durability, which sustains its unique heartbeat. The Cardiac hearts muscle has the capability to spread rapid electrochemical signals throughout the
