Question: What are the horns of gray matter?...

What are the horns of gray matter?

Explanation

Solution

As we know that, the central nervous system is made up of gray matter and white matter.
Grey matter is a component of the central nervous system, consisting of neuron cell bodies, synapses.
It is mainly located on the surface of the spinal cord and brain.
The grey matter in the center of the cord is shaped like a butterfly and consists of cell bodies of interneurons and motor neurons as well as neuroglia cells and unmyelinated axons.
However, grey matter plays the most significant part in allowing humans to function normally daily.

Complete answer:
Neural tissue, especially of the brain and spinal cord, contains nerve cell bodies as well as nerve fiber and has a brownish gray color called grey matter.
The gray matter is subdivided into regions that are referred to as horns.
The gray matter forms three pairs of horns through most of the spinal cord.
a) Dorsal horns composed of sensory neurons carrying sensory messengers.
It contains neurons that receive somatosensory information from the body.
Its function is to carry many incoming sensory neuron synapse with interneurons which then distribute information to other parts of the spinal cord and brain.
Dorsal horns are the thinner projections of dark matter that jut out from the back side of the spinal cord.
b) Lateral horns are well defined in thoracic segments and visceral neurons.
They are only found in the thoracic, upper lumbar and sacral regions.
They are primarily involved in the activity of synaptic division of the autonomic motor system.
c) Ventral horns largely contain motor neurons that exit the spinal cord to innervate skeletal muscle.
The intermediate column and lateral horn contain neurons that innervate visceral and pelvic organs.
The ventral horns are the wider projections of dark matter towards the ventral or front side of the spinal cord.
The grey matter throughout the central nervous system enables individuals to control movement, memory and emotions.
Grey matter forms early in development from the ectoderm. It gets its grey tone from a high concentration of neuronal cell bodies.
Many issues may affect the grey matter both in brain and spinal cord, one of the most prevalent medical problems occurs when plaque begins to build up in areas of grey matter within the brain.
These areas are known as sensile plaques, take up space that was once grey matter, leading to a decrease of higher functioning.
Very known disease which decreases cognitive function causing the patient to lose memory, a condition known as Alzheimer disease.
Besides this cognitive function, grey matter can also affect the motor function of the body. As the neurons in the substantia nigra begin to decrease the amount of dopamine that is released, the person will lose control of fine motor skills.
Trauma may also play a role in creating issues that stem from the gray matter.

Note:
Grey matter is present both in the spinal cord as well as the brain; their function is to carry neurons which lead the neuro activities of the body.
Gray matter consists of dendrites and soma which process the information. Processing of information is the conduction of neural activity.
It consists of predominantly neuronal cell bodies.
