Soma definition and function
When this change reaches a threshold level, this effect runs across the cell's membrane to the axon. The cell body is the spherical part of the neuron that contains the nucleus and connects to the dendriteswhich bring information to the neuron, and the axonwhich sends information to other neurons.

Dendrites play a critical role in integrating these synaptic inputs and in determining the extent to which action potentials are produced by the neuron. Usually a long process which often projects to distant regions of the nervous system. Type I is an excitatory synapse, generally found on dendrites, type II is an inhibitory synapse, generally found on cell bodies.
It contains organelleswhich are tiny organs in the cell that each do a specific job. Enrolling in a course lets you earn progress by passing quizzes and exams. In general, most proteins are produced from mRNAs that do not travel far from the cell nucleus.
