Basal dendrite

Basal Dendrite

A basal dendrite is a type of dendrite that extends laterally from the neuron's cell body. These dendrites are one of the primary sites for receiving and processing information within the nervous system.

Structure

Basal dendrites are typically shorter and branch more extensively than apical dendrites, another type of dendrite that extends from the apex of the neuron's cell body. The structure of basal dendrites allows them to receive a large number of synaptic inputs from other neurons.

Function

The primary function of basal dendrites is to receive and process information from other neurons. They do this by receiving neurotransmitters at their synapses, which can either excite or inhibit the neuron. The combined input from all of the neuron's synapses determines whether the neuron will fire an action potential, transmitting the information to other neurons.

Clinical Significance

Changes in the structure or function of basal dendrites can have significant effects on the nervous system. For example, some neurological disorders, such as schizophrenia and Alzheimer's disease, have been associated with abnormalities in dendritic structure.
