Dendrites

Dendrites are branch-like extensions of a neuron that receive information from other neurons and transmit electrical stimulation to the cell body. They play a crucial role in the communication network of the nervous system, allowing neurons to communicate with each other and process information.

Structure of Dendrites

Dendrites are covered in tiny protrusions called dendritic spines, which increase the surface area available for receiving signals from other neurons. These spines form synapses with axon terminals of other neurons, allowing the transfer of information through chemical and electrical signals.

Function of Dendrites

The main function of dendrites is to receive incoming signals from other neurons and transmit these signals to the cell body. This process is essential for integrating and processing information, ultimately influencing the firing of the neuron and the transmission of signals to other neurons.

Study Guide

1. Describe the structure of dendrites and their role in neuron communication.
2. Explain how dendritic spines contribute to the function of dendrites.
3. Discuss the importance of dendrites in the integration and processing of information within the nervous system.
4. Compare and contrast the functions of dendrites and axons in neuron communication.
