Skeletal muscle is functionally a voluntary muscle but the cardiac muscle is not. Shape of skeletal muscle fibre is cylindrical: that of cardiac muscle fibre is ribbon like. Moreover the cardiac muscle fibres are branched. Skeletal muscle fibre is syncytial, i.e. each cell contains multiple number of nuclei, but cardiac muscle fibre is uninucleated. Junction between two adjacent cardiac cells ...
Muscle cells and nerve cells (neurons) are two very different types of cells. Muscle cells (myocytes) contract to produce movement while nerve cells send messages from receptor cells to either glandular cells or muscle cells relaying messages throughout the body. While nerve cells are involved in the transmission of neural synapses (hence the name), myocytes contract to move the skeletal bones ...
The joints function as fulcrums, the bones function as levers, and the muscles provide the pull to move the levers. Lever are classified as type I, II, or III. In a class I lever system, the fulcrum is located between the pull and the weight. A child's seesaw is an example of this type of lever. The head is an example of this type of lever in ...
The number of mitochondria per cell varies widely depending on the cells energy requirements. Muscle cells need energy to do mechanical work and respond quickly. Thus a higher number of mitochondria is present so that the cells requirement of energy to perform its specific function is fulfilled. In humans, erythrocytes do not contain any ...
What are "anatomical" differences between skeletal, smooth, and cardiac muscle? Anatomy & Physiology Skeletal, Muscular, and Integumentary Systems Skeletal System 1 Answer
Bone cell is osteocyte while muscle cell is called myocyte. 1. Bones form infrastructure of skeletal system while muscles help in movement by contraction and relaxation. 2. Young bone cells secrete organic matrix of bony tissue. Myocytes do not secrete matrix. 3. Old bone cells are reabsorbed by osteoclast cells and new bone cells are generated from periosteum. Activity of osteoclasts increase ...
The cardiac muscles are made from muscle fibres in which the cells are branched and multinucleated while the skeletal muscles are made of muscle fibres in which the cells are band shaped and non nucleated. Answer link. The muscles of the heart are made to work tirelessely while the skeletal muscles get tired at some point The cardiac muscles ...
Mitochondria are the living organism energy generator. Accordingly, muscle cells are the living systems mechanical motor, thus it needs energy. The number of mitochondria in a cell can vary widely by organism, tissue, and cell type. For instance, red blood cells (i.e. the cells that can oxygen in the blood) have no mitochondria, they need to make no mechanical activity, whereas liver cells can ...
Explanation: The heart wall has three layers: Of these three layers myocardium is the thickest. this layer is composed of cardiac muscle cells. So, cardiac muscle cells make up most of the tissues of the heart. Cardiac muscle cell. The heart wall has three layers: endocardium myocardium pericardium Of these three layers myocardium is the ...
Here are some of the features of each type of muscle. > Skeletal Muscle (From theydiffer.com) 1. Function Aid in movement of the body 2. Structure Distributed throughout body Attached to the skeleton by tendons. Striated Well-supplied with nerves and blood vessels. Multinucleated cells 3. Other features Voluntary Activated by central nervous system Stretch and resume original shape. Contract ...
