Muscle Cell Types The structure of skeletal muscle cells also makes them unique among muscle tissues. Skeletal muscle cells develop from the fusion of many smaller cells during fetal development, resulting in long, straight muscle fibers that contain many nuclei.t forms all of the skeletal muscles, such as the biceps brachii and gluteus maximus, and is found in the eyes, throat, diaphragm, and anus.... Click to read more below. 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.

- Skeletal muscle is made up of individual muscle cells or myocytes, known as muscle fibers. They are formed from the fusion of developmental myoblasts (a type of embryonic progenitor cell that gives rise to a muscle cell) in a process known as myogenesis.Muscle fibres are cylindrical, and multinucleated.keletal muscle is made up of individual muscle cells or myocytes, known as muscle fibers.

What Organelle Must Be Present in Large Numbers in Muscle Cells? Muscle cells have special characteristics that make them more effective in their primary task of accomplishing movement through contraction. The three general types of muscle tissue -- smooth, cardiac and skeletal -- all contain elongated cells known also as muscle fibers.n Abundance of Energy. All cells need energy to function, but muscle cells have unusually high energy requirements. They resist the force of gravity, generate heat by shivering, pump blood, move substances through hollow organs and produce strong bodily movements.

- A muscle cell is a special kind of cell that makes up an organism's muscle tissues. The muscles allow independent movement and regulate biological functions such as digestion and heartbeat.keletal muscle structure. Different types of muscle tissue. An organism's muscle tissue is composed of muscle cells. Multi-unit smooth muscle cells operate independently and single-unit, or visceral, smooth muscle cells operate together as a unit.

Muscle Cell Functions Smooth muscle cells contract for a longer period of time and with less force than skeletal muscle cells. Cardiac Muscle Cells. Heart, or cardiac, muscle cells have structural and functional characteristics of both skeletal and smooth muscle cells. Your heart muscle cells are highly coordinated to contract together with each heartbeat.

Myocyte Skeletal muscle fibers are made when myoblasts fuse together; muscle fibers therefore have multiple nuclei (each nucleus originating from a single myoblast). The fusion of myoblasts is specific to skeletal muscle (e.g., biceps brachii) and not cardiac muscle or smooth muscle.

skeletal muscle Some skeletal muscles are broad in shape and some narrow. In some muscles the fibers are parallel to the long axis of the muscle; in some they converge to a narrow attachment; and in some they are oblique. Each skeletal muscle fiber is a single cylindrical muscle cell.An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering. Each muscle is surrounded by a connective tissue sheath called the epimysium.Fascia, connective tissue outside the epimysium, surrounds and separates the muscles.ach skeletal muscle fiber is a single cylindrical muscle cell.

Cardiac Muscle Tissue The passage of signals from cell to cell allows cardiac muscle tissue to contract very quickly in a wave-like pattern to effectively pump blood throughout the body. Another feature that is unique to cardiac muscle tissue is autorhythmicity.ardiac muscle tissue is able to set its own contraction rhythm due to the presence of pacemaker cells that stimulate the other cardiac muscle cells. The pacemaker cells normally receive inputs from the nervous system to increase or decrease the heart rate depending on the body’s needs.

RIXIMKA DUMARKA Smooth muscle is an involuntary non-striated muscle. It is divided into two subgroups; the single-unit (unitary) and multiunit smooth muscle.Within single-unit cells, the whole bundle or sheet contracts as a syncytium (i.e. a multinucleate mass of cytoplasm that is not separated into cells). In smooth muscle, there is a single gene (MYH11) that codes for the heavy chains myosin II, but there are splice variants of this gene that result in four distinct isoforms. 2  Also, smooth muscle may contain MHC that is not involved in contraction, and that can arise from multiple genes.

What makes a muscle cell specialized? exists and is an alternate of. Merge this question into. Split and merge into it. Answer by Cowleya. Confidence votes 10.3K. Muscle cells, like all cells, are specialised to carry out their specific functions. Muscle cells need relatively large numbers of mitochondria.This is because they respire more than most other types of cell, in order to release the energy for muscle contraction, and hence movement.xists and is an alternate of.

Muscular System Anatomy Skeletal Muscle Histology. Skeletal muscle fibers differ dramatically from other tissues of the body due to their highly specialized functions. Many of the organelles that make up muscle fibers are unique to this type of cell. The sarcolemma is the cell membrane of muscle fibers.

Which Muscle Cells Have the Greatest Ability to Regenerate? These cells can be replaced when smooth muscle is injured by trauma, surgery or disease. While during regeneration of skeletal muscle, only nearby precursor or satellite cells become activated and are the source of new muscle tissue, all smooth muscle cells have the ability to divide and form new smooth muscle.he cells in multi-unit muscles can function independently of each other, while the muscle cells of single-unit muscles work together as a unit. An example of multi-unit muscle cells are the cells that constrict or dilate the iris of the eye.
