Myocytes: Structure, Function & Diseases

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

Cytoplasm: 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

Cytosol: Function & Diseases

Cytosol is the fluid portion of the contents of a human cell and thus part of the cytoplasm. The cytosol is composed of about 80% water, with the remaining portion distributed among proteins, lipids, nucleotides, sugars, and ions. They serve important metabolic processes that take place in the aqueous to viscous cytosol. What is cytosol? … Cytosol: Function & Diseases

Differences to the cell membrane of bacteria – Penicillin | Cell membrane

Differences to the cell membrane of bacteria – Penicillin The cell membrane of bacteria is hardly different from that of the human body. The big difference between the cells is the additional cell wall of the bacteria. The cell wall attaches itself outside the cell membrane and in this way stabilizes and protects the bacterium, … Differences to the cell membrane of bacteria – Penicillin | Cell membrane

Cell membrane

Definition Cells are the smallest, coherent units from which organs and tissues are built. Each cell is surrounded by a cell membrane, a barrier consisting of a special double layer of fat particles, the so-called lipid double layer. Lipid bilayers can be imagined as two fat films lying on top of each other, which cannot … Cell membrane

What are the components of the cell membrane? | Cell membrane

What are the components of the cell membrane? Basically, the cell membrane is composed of a phospholipid bilayer. Phospholipids are building blocks consisting of a water-loving, i.e. hydrophilic, head and a tail formed by 2 fatty acids. The part consisting of fatty acids is hydrophobic, which means that it repels water. In the bilayer of … What are the components of the cell membrane? | Cell membrane

Functions of the cell membrane | Cell membrane

Functions of the cell membrane As the complex structure of cell membranes already suggests, they have many different functions to fulfil, which can vary greatly depending on the type and localisation of the cell. On the one hand, membranes generally represent a barrier. A function that should not be underestimated. In our body, countless reactions … Functions of the cell membrane | Cell membrane

What are Mitochondria?

In order to survive, the human body needs energy. This is obtained from food and then enters the cells via the blood. However, in order to be used or stored there, it must first be “burned” – much like gasoline in an engine. This is the job of the mitochondria, which are therefore also known … What are Mitochondria?

Rods: Structure, Function & Diseases

Rods are the retinal photoreceptors responsible for light-sensitive monochromatic night vision and peripheral vision. The main concentration of rods is outside the yellow spot (fovea centralis) located centrally on the retina, which is mainly populated with three different types of cones for color and sharp vision during the day and in bright twilight. What are … Rods: Structure, Function & Diseases
