DENDRITE Meaning and
Definition
-
A dendrite, in the field of biology and neuroscience, refers to the branch-like extension of a nerve cell or neuron that receives signals from other neurons. Derived from the Greek word "dendron," meaning "tree," dendrites resemble the intricate branches of a tree, allowing them to connect with and receive information from multiple sources. Dendrites play a crucial role in the transmission of electrical signals, or nerve impulses, between neurons, forming a network for information exchange within the nervous system.
At a microscopic level, dendrites are covered in small protrusions called dendritic spines, which further increase their surface area for receiving signals. These spines contain synapses, specialized junctions that permit communication between neurons by transmitting chemical or electrical signals. Dendrites collect and integrate these signals, assessing their strength and relevance before passing them on to the cell body, or soma, of the neuron.
Dendrites can vary in size, shape, and complexity depending on their location within the nervous system and the type of neuron they belong to. They are most commonly found in the brain and spinal cord, where they form dense networks responsible for processing information and modulating neural activity. The morphology and connectivity of dendrites contribute to the neural plasticity and overall functioning of the nervous system.
In summary, dendrites are the treelike extensions of neurons that receive signals and play a crucial role in the transmission of information within the nervous system.

Common Misspellings for DENDRITE
Etymology of DENDRITE
The word "dendrite" comes from the Greek word "dendron", which means "tree". This is because the branching structure of a dendrite, found in various biological contexts, such as neurons and mineral formations, resembles the branching of a tree. The suffix "-ite" is a common ending in chemistry, indicating the presence of a particular substance or compound.
