- Like other cells, each neuron has a cell body (or soma) that contains a nucleus, smooth and rough endoplasmic reticulum, Golgi apparatus, mitochondria, and other cellular components. Neurons also contain unique structures, illustrated in Figure 1 for receiving and sending the electrical signals that make neuronal communication possible.

Jan 16, 2024 · Although there are billions of neurons and vast variations, neurons can be classified into three basic groups depending on their function: sensory neurons (long dendrites and short axons), motor neurons (short dendrites and long axons), and relay neurons (short dendrites and short or long axons).
Neurons have all the morphological counterparts of other cell types, the structures are similarly distributed and some of the most common, the Golgi apparatus and mitochondria, for example, were described first in neurons .

Aug 3, 2024 · Different types of neurons include sensory, motor, and interneurons, as well as structurally-based neurons, which include unipolar, multipolar, bipolar, and pseudo-unipolar neurons. These cells coordinate bodily functions and movement so quickly, we don't even notice it happening.
A neuron contains all the structures of other cells such as a nucleus, mitochondria, and Golgi bodies but has additional unique structures such as an axon, and dendrites. [4] . The soma is a compact structure, and the axon and dendrites are filaments extruding from the soma.
Jun 28, 2020 · A neuron is a single nervous system cell that receives, processes, and transmits electrochemical messages from and to other cells. Neurons connect different areas of the central and peripheral nervous systems.
Oct 31, 2023 · Learning Objectives. Describe the functions of the structural components of a neuron. The nervous system of the common laboratory fly, Drosophila melanogaster, contains around 100,000 neurons, the same number as a lobster. This number compares to 75 million in the mouse and 300 million in the octopus.
