The branching extensions of a neuron that receive messages and conduct impulses toward the cell body are called dendrites. Dendrites are specialized structures that serve as the main input site for receiving information from other neurons or sensory receptors. They appear as numerous small, tree-like projections that extend from the cell body of a neuron.

The primary function of dendrites is to collect electrical signals or messages from neighboring neurons. These signals are transmitted from the axon terminals of other neurons, across small gaps called synapses, and then received by the dendrites. The dendrites contain receptor sites or specialized protein molecules that facilitate the recognition and binding of specific neurotransmitter molecules released by other neurons.

Once the neurotransmitter molecules bind to the receptor sites on the dendrites, they initiate a series of chemical reactions that result in the generation of electrical impulses or action potentials. These electrical signals then travel along the dendrites towards the cell body of the neuron. The dendrites play a crucial role in integrating and summing up these incoming signals before transmitting them to the cell body.

The structure of dendrites is highly complex, with many small branches called dendritic spines, which further increase the surface area available for signal reception. The large surface area and extensive branching of dendrites allow neurons to receive and process multiple signals simultaneously from various inputs, enabling complex signaling and information processing within the nervous system.

Overall, dendrites serve as the primary receivers of information in neurons, enabling the integration and transmission of electrical impulses towards the cell body, where further processing and transmission of signals occur.
