Neurite

Neurite is the term used to describe the cell extension of a nerve cell through which electrical impulses are transmitted to its environment. If the neurite is also surrounded by “glial cells” that isolate it, it is called an axon. Function and structure A neurite is the extension of a nerve cell, and directs its … Neurite

Nerve fiber

A nerve fiber is a portion of a nerve. A nerve is composed of several nerve fiber bundles. These nerve fiber bundles contain many nerve fibers. Each nerve fiber is surrounded by the so-called endoneurium, a kind of protective mantle around each nerve fiber. The endoneurium consists of connective tissue and elastic fibres and because … Nerve fiber

Function | Nerve cell

Function Nerve cells are able to process input signals and transmit new signals based on them. A distinction is made between excitatory and inhibitory nerve cells. Exciting nerve cells increase the probability of an action potential, while inhibiting ones reduce it. Whether a nerve cell excites or not depends basically on the neurotransmitter that this … Function | Nerve cell

Which different nerve cells are there? | Nerve cell

Which different nerve cells are there? Nerve cells can be classified according to various criteria. Afferent cells send signals to the central nervous system (sensory), while efferent cells send signals to the periphery (motor). Particularly within the brain, a distinction can also be made between excitatory and inhibitory neurons, whereby inhibitory neurons usually have a … Which different nerve cells are there? | Nerve cell

Acetylcholine at the heart | Acetylcholine

Acetylcholine at the heart As early as 1921 it was discovered that a chemical substance must be present which transmits the electrical impulse transmitted via the nerves to the heart. This substance was initially called vagus substance after the nerve whose impulse it transmits. Later it was chemically correctly renamed acetylcholine instead. The nervus vagus, … Acetylcholine at the heart | Acetylcholine
