English: Complete neuron cell diagram. Neurons (also known as neurones and nerve cells) are electrically excitable cells in the nervous system that process and transmit information. In vertebrate animals, neurons are the core components of the brain, spinal cord and peripheral nerves.

A neuron (also known as a neurone or nerve cell) is an excitable cell in the nervous system that processes and transmits information by electrochemical signaling. Neurons are the core components of the brain, spinal cord, and peripheral nerves.
In neuroanatomy, a nucleus (pl.: nuclei) is a cluster of neurons in the central nervous system, [1] located deep within the cerebral hemispheres and brainstem. [2] The neurons in one nucleus usually have roughly similar connections and functions. [ 3 ]
For instance, the soma of a neuron can vary from 4 to 100 micrometers in diameter. [7] The soma is the body of the neuron. As it contains the nucleus, most protein synthesis occurs here. The nucleus can range from 3 to 18 micrometers in diameter. [8] The dendrites of a neuron are cellular extensions with many branches. This overall shape and ...
The soma of a neuron (i.e., the main part of the neuron in which the dendrites branch off of) contains many organelles, including granules called Nissl granules, which are composed largely of rough endoplasmic reticulum and free polyribosomes. [5] The cell nucleus is a key feature of the soma.
The gracile nucleus is medial to the cuneate nucleus. [5] Its neurons receive afferent input from dorsal root ganglia sensory neurons of the lower torso and the lower limbs . [ 5 ] The gracile nucleus and gracile fasciculus carry epicritic , kinesthetic , and conscious proprioceptive information from the lower part of the body (below the level ...
The posterior thoracic nucleus is a major relay center for unconscious proprioception.Sensory information from muscle spindles and tendon organs is carried by axons of larger neurons in dorsal root ganglia, which synapse onto neurons in the spinal cord including the posterior thoracic nucleus.
