A dendrite (from Greek δένδρον déndron, "tree") or dendron is a branched cytoplasmic process that extends from a nerve cell that propagates the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project.
A dendrite is a branching projection of the cytoplasm of a cell. While the term is most commonly used to refer to the branching projections of neurons, it can also be used to refer to features of other types of cells that, while having a similar appearance, are actually quite distinct structures. [1] Non-neuronal cells that have dendrites:

The soma of a neuron (i.e., the main part of the neuron in which the dendrites branch off of) contains many organelles, including granules called Nissl granules, which are composed largely of rough endoplasmic reticulum and free polyribosomes. [5] The cell nucleus is a key feature of the soma.
Dendrite (metal), a characteristic tree-like structure of crystals growing as molten metal freezes; Dendrite (mathematics), a locally connected continuum that contains no simple closed curves; Dendrite (crystal), a crystal that develops with a typical multi-branching tree-like form; Dendrimer, a repetitively branched molecule
In neuroscience, retrograde signaling (or retrograde neurotransmission) refers more specifically to the process by which a retrograde messenger, such as anandamide or nitric oxide, is released by a postsynaptic dendrite or cell body, and travels "backwards" across a chemical synapse to bind to the axon terminal of a presynaptic neuron.

In biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. [ 1 ]
