Can mitochondria multiply? In principle, the organism can regulate the production of mitochondria up or down. The decisive factor for this is the current energy supply of the organ in which the mitochondria are to be multiplied. A lack of energy within these organ systems ultimately leads to the development of so-called growth factors via … Can mitochondria multiply? | Mitochondria
Glutamine is a non-essential proteinogenic amino acid. It plays a central role in the organism in all metabolic processes and in building proteins. Glutamine is most abundant in the free pool of amino acids. What is glutamine? Glutamine represents a non-essential amino acid, which contains an acid amide group in addition to the amino group … Glutamine: Function & Diseases
Definition The synaptic gap is a space between two communicating nerve cells that plays an important role in the transmission of action potentials (nerve impulses). In it a modulation of signal transmission takes place, which has a great pharmacological importance. Construction of a synaptic cleft A synapse is the transition between two nerve cells or … Synaptic cleft
Functionality of chemical synapses Whenever a nerve cell sends a signal to a muscle, gland or other nerve cell, the transmission takes place via the synaptic gap, which is only about 20-30 nanometers wide. The long extensions of the nerve cells (also called “axons”) conduct the nerve impulse (i.e. the “action potential“) from the center … Functionality of chemical synapses | Synaptic cleft
Simplified pictorial representation For better understanding the following illustration: A group of hikers (=action potentials) wants to cross a river (=synaptic cleft) with boats (=synaptic vesicles), but there is only one docking and undocking point per side (=pre- & postsynaptic membrane). If they have successfully crossed the flow, they can continue their migration on the … Simplified pictorial representation | Synaptic cleft
Introduction The cerebrum is probably the most widely known part of the brain. It is also called the endbrain or telencephalon and makes up the largest part of the human brain. It is only present in humans in this form and size. Roughly speaking, the cerebrum is divided into four lobes, which are named in … Tasks of the cerebrum
Tasks of the cerebral cortex The cerebral cortex, also known as the cortex cerebri, is visible from the outside and envelops the brain. It is also known as the grey matter, because in a fixed state it appears greyish in relation to the cerebral medulla. The cerebral cortex contains the nerve cores of the nerve … Tasks of the cerebral cortex | Tasks of the cerebrum
Tasks of the cerebral medulla The cerebral medulla is also known as the white matter. It consists of a network of supply and support cells between which the nerve processes, the axons, run in bundles. These bundles are combined into pathways. There are no cell bodies in the white matter. Their task is therefore to … Tasks of the cerebral medulla | Tasks of the cerebrum
Cooperation of the cerebrum with the cerebellum The cerebellum lies at the back of the skull, below the cerebrum. Also known as the cerebellum, it serves as a control centre for the coordination, learning and fine-tuning of movement sequences. It receives information from the organ of equilibrium in the ear, the spinal cord, the eyes, … Cooperation of the cerebrum with the cerebellum | Tasks of the cerebrum
All life originates from the sea. Therefore, there are conditions in the body that build on these original conditions of life. This means that vital building blocks in the organism are salts. They enable all physiological processes, are part of the organs and form ions in aqueous solution. Sodium and potassium chloride are dominant salts … Membrane Potential: Function, Role & Diseases
Synonym axial cyinder, Neurit General information The term axon is used to describe the tubular extension of a nerve cell that transmits impulses originating from the nerve cell body to the farthest reaches. Within the axon is a fluid, the axoplasm, which corresponds to the cell content (cytoplasm) of other cells. Here are cell organelles … Axon
Tasks An axon fulfils two important tasks: First, it is there to transmit the electrical impulses generated in the nerve cell body to the next nerve cell or to the target structure (muscle or gland cell). – In addition, some substances are transported along certain structures through the axon. This process, known as axonal transport, … Tasks | Axon
