What is Dendrite?
Definition: Dendrites are branch-like extensions of a neuron that receive incoming signals from other neurons and relay them to the cell body.
Characteristics: Dendrites have a tree-like structure with numerous branches that increase their surface area for receiving signals. They taper in diameter as they extend outward from the cell body.
Function: The main function of dendrites is to receive and integrate incoming signals from other neurons. They act as the primary site for synaptic input, where they receive neurotransmitter molecules released by neighbouring neurons. These signals, once received and integrated, determine whether the neuron will generate an action potential and transmit information further through its axon.
Difference Between Axon and Dendrite
Difference Between Axon and Dendrite: Two parts of nerve cells are axons and dendrites. The structural and functional fundamentals of an animal’s nervous system are called nerve cells. In order to coordinate the body’s operations, they send nerve impulses to the brain, spinal cord, and body. An axon is a long, conical extension of the nerve cell’s cell body. There is an axon in every nerve cell. Dendrites are the brief structures that emerge from the cell body. A nerve cell has a large number of dendrites. Axons and dendrites differ essentially in that dendrites transport nerve impulses back to the cell body from synapses, whereas axons carry nerve impulses away from the cell body.
