What are dendrites?

Dendrites are the branch-like structures that extend from the cell body of a neuron. They act as the main receiving site for incoming signals from other neurons.

Structure of dendrites

Dendrites are covered in tiny protrusions called dendritic spines, which increase the surface area available for receiving signals. This structure allows dendrites to receive and process multiple signals simultaneously.

Function of dendrites

The primary function of dendrites is to receive signals from other neurons and transmit these signals to the cell body. This process is essential for the communication between neurons, which ultimately allows for the transmission of information throughout the nervous system.

Role in neural communication

When an electrical signal reaches the end of an axon of a neighboring neuron, it triggers the release of neurotransmitters. These neurotransmitters bind to receptors on the dendrites, initiating a new electrical signal in the receiving neuron. This process is crucial for the transmission of information within the nervous system.

Importance of dendrites

Dendrites play a critical role in the integration of signals received by a neuron. The combined input from multiple dendrites determines whether the neuron will generate an electrical signal, known as an action potential, and transmit the signal further along the neural pathway.
