Definition Dendrites are the cytoplasmic extensions of a nerve cell, which usually branch off from the nerve cell body (soma) in a knot-like manner and become more and more finely branched in two parts. They serve to receive electrical stimuli from upstream nerve cells via synapses and transmit them to the soma. The dendrites also … Dendrit
Spinous processes Dendrites that do not have a spinous process are called “smooth” dendrites. They pick up nerve impulses directly. While the dendrites have the spines, the nerve impulses can be absorbed through the spines as well as through the dendrite trunk. The thorns emerge from the dendrites like little mushroom heads. They can increase … Spinous processes | Dendrit
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
