Myocytes are multinucleated muscle cells. They make up the skeletal muscles. In addition to contraction, energy metabolism also falls within their range of functions. What are myocytes? Myocytes are spindle-shaped muscle cells. Myosin is a protein that plays an important role in their anatomy and function. Antoni van Leeuwenhoek first described muscle cells in the … Myocytes: Structure, Function & Diseases
Sphingolipids are among the building blocks of the cell membrane, along with glycerophospholipids and cholesterol. Chemically, they are derived from sphingosine, an unsaturated amino alcohol with 18 carbon atoms. Mainly nervous system and brain are rich in sphingolipids. What are sphingolipids? All cell membranes contain glycerophospholipids, cholesterol and sphingolipids. Sphingolipids consist of the backbone sphingosine, … Sphingolipids: Function & Diseases
The branch-like and multiply branched cytoplasmic processes of a nerve cell (neuron), through which information is received and impulses are transmitted to the body, is referred to in technical language as the dendrite. This serves to receive electrical stimuli and transmits them to the cell body (soma) of the nerve cell. What is a dendrite? … Dendrite: Structure, Function & Diseases
Fibroblasts are anabolic cells. They produce all the fibers and molecular components of connective tissue, giving it its structure and strength. What are fibroblasts? Fibroblasts are connective tissue cells in the strict sense. They are motile and divisible and produce all the important components of intercellular substance. This is the basic structure in tissue into … Fibroblasts: Structure, Function & Diseases
Fibrocytes are part of the connective tissue. They are normally in a resting state and have irregular projections that join with the projections of other fibrocytes to give connective tissue three-dimensional strength. When needed, such as after mechanical injury, fibrocytes can “awaken” from their dormancy and revert to fibroblasts by dividing to synthesize components of … Fibrocyte: Structure, Function & Diseases
Progenitor cells have pluripotent properties and form the reservoir in various tissues from which somatic tissue cells are formed by proliferation and differentiation. They are generated by asymmetric division of pluripotent stem cells, one of which develops as a progenitor cell and the other of which completes the reservoir of stem cells again. Progenitor cells … Progenitor Cell: Structure, Function & Diseases
In apocytosis, the membrane of a glandular cell is sequestered along with the secretion in containers. This is a secretory mode of apocrine glands that is a special form of exocytosis and primarily affects the mammary gland. Disorders of hormonal balance may alter apocytosis behavior. What is apocytosis? It is a secretion mode of apocrine … Apocytosis: Function, Role & Diseases
Beta-secretase belongs to the protease family. It is involved in the formation of beta-amyloid, which plays important roles in information transmission in the brain. At the same time, beta-secretase and beta-amyloid play important roles in the development of Alzheimer’s disease. What is beta-secretase? Beta-secretase belongs to the group of proteases that break down proteins at … Beta-secretase: Function & Diseases
The geniohyoid muscle is one of the suprahyoid muscles that together open the jaw and participate in swallowing. The hypoglossal nerve is responsible for the nervous supply to the geniohyoid muscle. Accordingly, hypoglossal nerve palsy impairs the function of the muscle and causes dysphagia, which can occur in the context of numerous neurologic, muscular, and … Geniohyoid Muscle: Structure, Function & Diseases
The cytoplasm fills the interior of a human cell. It consists of the cytosol, a liquid or gel-like substance, the organelles (mitochondria, Golgi apparatus, and others), and the cytoskeleton. Overall, the cytoplasm serves enzymatic biosynthesis and catalysis as well as substance storage and intracellular transport. What is cytoplasm? The definition of cytoplasm is not uniform … Cytoplasm: Structure, Function & Diseases
Definition Cell plasma or cytoplasm is the complete content of the cell with the exception of cell organelles. Cytoplasm is an organic fluid that forms the basic substance of every cell. Besides water, cytoplasm consists mainly of proteins, nutrients and enzymes that are essential for the cell’s function. Function of the cell plasma The cytoplasm … Cell plasma in the human body
What is the cell membrane? In prokaryotic and eukaryotic cells, the cell membrane describes the envelope of the cell plasma. Thus, the cell membrane protects the cell from external influences. The basic structure of the cell membrane is the same for all cells. The basic structure is a double fat layer (lipid bilayer). This consists … What is the cell membrane? | Cell plasma in the human body
