A neuron is the smallest part of a nerve, or the most basic unit of the nervous system and is a cell that carries electrical impulses to and from the brain. The brain, though a very complex organ of the human body, yet is the most vital one for the proper functioning of each and every other organ present in the body. Hence, a detailed understanding of it from a person who has been attached solely to the study of the brain, namely, Dr. Curtis Cripe would be an excellent thing to do.
Dr. Cripe is presently associated with the NTL Group as the Science Research and Development Director. He has diverse erudition on everything related to neuroengineering, psychology, aero space engineering, brain injury, recovery from addiction, as well as child neuro development.
His contribution to the world of medicine has been greatly appreciated when he laid the foundation of the Crossroads Institute. This institute is renowned to have used telemedicine brain training delivery systems; this system helps a child with his/her learning and developmental difficulties, as also helps an adult who are constantly battling some kind of addiction or traumatic injury of the brain.
The neurons in the brains are interconnected yet they do not touch each other, it is a very interesting fact that there are tiny spaces or synapses in between the neurons and they send signals to each other at an unimaginably high speed. A neuron structure typically has three parts – the cell body also called the soma, the dendrites and the axon. The classification of neurons is based on two things : connection and function.
Based on connection, a neuron can be further distinguished as afferent neurons, efferent neurons and interneuron. To transmit information from the tissues and organs to the central nervous system is the job of the afferent neurons; the efferent neurons on the other hand take the information from the central nervous system to the effecter cells. And the interneurons connect the central nervous system and the neurons.
When it comes to the functionality of the neurons, they can be further classified into three categories:
- Sensory neurons – these help in carrying signals to the brain and the spinal cord from the sense organs.
- Relay neurons – these help in conveying the signals the motor neurons also known as the sensory neurons and the central nervous system.
- Motor neurons – these are connected to the relay neurons and carry the signals further on from the central nervous system to the muscles.
Experts in the understanding of neurons such as Dr. Curtis Cripe will be able to give detailed explanation on how these primary components of the central nervous system(CNS), are responsible for the proper functioning of the brain and the spinal cord. He will also be able to give amusing facts about these tiny nerve cells as to how the signaling system, which is partly electrical and partly chemical, works through the synapses, and aids in the optimal functioning of the body.
