Dendrites are the branch-like structures that extend from the cell body of a neuron. They act as the receiving end of the neuron, gathering information from other neurons and transmitting it to the cell body.
Dendrites are covered in tiny projections called dendritic spines, which increase the surface area available for receiving signals from other neurons. These spines play a crucial role in synaptic transmission and plasticity.
The main function of dendrites is to receive signals from other neurons and transmit these signals to the cell body. The dendrites integrate these signals and, if the combined input is strong enough, they generate an electrical signal that travels down the axon to communicate with other neurons.
