Soma: The Cell Body of Neurons

The soma, also known as the cell body, is a critical part of a neuron. It contains the nucleus and other organelles necessary for the neuron's function.

Anatomy of the Soma

The soma is the rounded, central part of the neuron. It contains the cell nucleus, which houses the genetic material of the neuron. Additionally, the soma contains various organelles such as the endoplasmic reticulum, Golgi apparatus, and mitochondria, which are essential for the neuron's metabolic activities.

Function of the Soma

The soma plays a crucial role in integrating the signals received by the neuron's dendrites and initiating the transmission of signals along the axon. It also carries out essential metabolic functions to support the neuron's overall health and functioning.
