The Cell Cells are the basic units of life; small machines that facilitate and sustain every process within a living organism. Muscle cells contract to maintain a heartbeat and allow us to move, neurons form networks that give rise to memories and enable thought processes. Epithelial cells arrange to form surface barriers between tissues and the many cavities throughout our bodies.

Myocyte A myocyte (also known as a muscle cell) is the type of cell found in muscle tissue.Myocytes are long, tubular cells that develop from myoblasts to form muscles in a process known as myogenesis.ach muscle fiber contains myofibrils, which are very long chains of sarcomeres, the contractile units of the cell. A cell from the biceps brachii muscle may contain 100,000 sarcomeres. The myofibrils of smooth muscle cells are not arranged into sarcomeres. The sarcomeres are composed of thin and thick filaments.

Muscle tissue Muscle tissue is a soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract. This is opposed to other components or tissues in muscle such as tendons or perimysium. It is formed during embryonic development through a process known as myogenesis. Muscle tissue varies with function and location in the body. In mammals the three types are: skeletal or striated muscle; smooth or non-striated muscle; and cardiac muscle, which is sometimes known as semi-striated.

Muscle Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell. Muscles function to produce force and motion.uscle tissues are derived from the mesodermal layer of embryonic germ cells in a process known as myogenesis. There are three types of muscle, skeletal or striated, cardiac, and smooth.

Muscle Cell Functions Skeletal muscle cells come in slow-twitch and fast-twitch varieties. Slow-twitch muscle cells are adapted for endurance activities and maintaining posture. Fast-twitch muscle fibers are adapted for rapid movements and activities that require maximum effort, such as jumping and lifting. Smooth Muscle Cells

- muscle. the contractile tissue that effects the movement of and within the body. Muscle tissue in the higher animals is classified as striated, smooth, or cardiac, according to its structure and function. Striated, or skeletal, muscle forms the bulk of the body's muscle tissue and gives the body its general shape.

Muscle noun, plural: muscles'. An organ made up of muscle tissues, or the tissue itself, enabling contraction or tension in an animal body to effect movement or locomotion. Supplement. Muscles are a specialized body part that produces movement or locomotion in animals. The muscle is comprised (largely) of muscle tissues.

- Hundreds or thousands of muscle fibers (cells) bundle together to make up an individual skeletal muscle. Muscle cells are long, cylindrical structures that are bound by a plasma membrane (the sarcolemma) and an overlying basal lamina and when grouped into bundles (fascicles) they make up muscle.

What do muscle cells do? Answer by Shania60. Confidence votes 21. the function of a muscle cell is, by definition, to move. this can be accomplished when the cell contracts. contracting makes it denser, which is why when you feel a relaxed muscle in your arm suddenly tense up, it hardens.nswer by Shania60.

muscle muscle. the contractile tissue that effects the movement of and within the body. Muscle tissue in the higher animals is classified as striated, smooth, or cardiac, according to its structure and function. Striated, or skeletal, muscle forms the bulk of the body's muscle tissue and gives the body its general shape.It is called striated because it appears striped, in alternating bands of light and dark, when viewed under a microscope, and animals have conscious control over most of their striate muscles.ll types of muscles consist of muscle fibers. Striated muscle fibers in skeletal muscles form bundles joined together by layers of connective tissue. The ends of muscle fibers are intertwined with tendon fibers, and through this combination muscular tension is transmitted to the skeletal bones.

Muscle tissue An isolated cardiac muscle cell, beating. Cardiac muscle (heart muscle) is involuntary striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium.Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle.These three types of muscle all form in the process of myogenesis. The cells that constitute cardiac muscle, called cardiomyocytes or myocardiocytes, contain only three nuclei.oordinated contractions of cardiac muscle cells in the heart propel blood out of the atria and ventricles to the blood vessels of the left/body/systemic and right/lungs/pulmonary circulatory systems. This complex mechanism illustrates systole of the heart.

muscle A body tissue composed of elongated cells (called muscle fibers) that contract to produce movement. In vertebrate animals, voluntary movement is produced by the action of muscles on bone. Movement of the muscles of the heart and other organs is involuntary and controlled by the autonomic nervous system.

Muscle Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell.ll muscle cells produce adenosine triphosphate (ATP) molecules which are used to power the movement of the myosin heads. Muscles have a short-term store of energy in the form of creatine phosphate which is generated from ATP and can regenerate ATP when needed with creatine kinase.

- Muscle Cell Types. Muscle tissue, one of the four major tissue types, plays the vital role of providing movement and heat generation to the organs of the body. Within muscle tissue are three distinct groups of tissues: skeletal muscle, cardiac muscle, and smooth muscle. Each of these tissue groups is made of specialized cells that give the tissue its unique properties. Skeletal muscle is the most common and widely distributed muscle tissue in the body, making up around 40% of the body’s total mass.

Muscle tissue The cells that constitute cardiac muscle, called cardiomyocytes or myocardiocytes, contain only three nuclei. The myocardium is the muscle tissue of the heart, and forms a thick middle layer between the outer epicardium layer and the inner endocardium layer.ardiac muscle cells, unlike most other tissues in the body, rely on an available blood and electrical supply to deliver oxygen and nutrients and remove waste products such as carbon dioxide. The coronary arteries help fulfill this function.
