Web28 Jan 2024 · Its main function is to receive impulses from other neurons and send them to the neuron’s soma. Dendrites are parts of neurons that are found throughout the body, that is, both in the brain and spinal cord and in those that are in the ganglia, internal organs, muscles, etc. Specifically, dendrites are small branches that come out of the cell ... Web10 Apr 2024 · Synapse is a neuronal junction that facilitates the transmission of an electrical signal from one neuron to another or from a neuron to an effector cell such as a muscle cell. There are two types of synapses: chemical synapse and electrical synapse.
