Definition:

The dendritic tree is the elaborate branching structure formed by the dendrites of a neuron. It consists of thin, treelike extensions protruding from the cell body, which receive and integrate incoming signals from other neurons.

Structure:

The dendritic tree is composed of numerous dendrites, each branching multiple times to form a complex network. These branches can extend both near and far from the cell body, creating a vast receptive surface area for receiving incoming electrical signals.

Function:

The primary function of the dendritic tree is to receive and process incoming signals from other neurons. Dendrites contain receptor sites that bind to neurotransmitters released by neighboring neurons. Through this process, dendrites play a crucial role in synaptic transmission and information processing within the brain.

Integration:

The dendritic tree integrates incoming signals by summing the electrical potentials received from various synapses. This integration occurs at specialized areas called dendritic spines, where synaptic inputs are concentrated. The collective input received by the dendritic tree determines whether the neuron will generate an action potential, thus influencing neural communication and the transmission of information through neural networks.
