Key Aspects Of The Brain And The Nervous System
The entire human body activity relies on the brain function, in this first section of this report I will try to discuss the major structures, the functions as well as the major methods of studying the brain. The brain is in charge of all body functions, such as the ability to make decisions, do activities, learning and all everyday life stuff. The brain is situated in the skull protected by brain blood fluid.
In the second section I will discuss the differences between Glial Cells and Neurones in relation to their structure and function, including the communication process amongst the Neurones and various types of Neurotransmitters as well as the conducts with which …show more content…
3. The Differences Between the Central Nervous system, the Peripheral Nervous System and the Two Branches of the Autonomic System.
The Nervous system correlates body activities and allocates signals to and from various areas of the body in vertebrate species. There are two key sections of the nervous system, they are the Central Nervous System and the Peripheral Nervous System, they each have different functions (Wikipedia en.m).
• The Central Nervous System, “ the part of the nervous system that includes the brain and the spinal cord” (Merriam-Webster Dictionary). It keeps, perceives and presents the information accordingly.
• The Peripheral Nervous System is the section of the nervous system which comprises of “nerves and ganglia in the exterior of the brain and spinal cord”en. m Wikipedia). Their key role is to link the Central Nervous System, all parts of the body and it is an essential communication system back and forth the spinal cord and the brain as well as the entire body.
These sections of the nervous system are governed by the Neurones, they differ in their purpose, substantial support, and in administering substance signature, below is my attempt to pen down their …show more content…
It diffuses across a synapse to effect the transmission of a nerve impulse to a nerve fibre. They are categorised in accordance to their molecular structure or function
Major neurotransmitters include;
Acetylcholine which takes a role of a neuromuscular link, excitory neurotransmitter, it and a compound of acetic and choline. On release it holds to the “post-synaptic receptors and Acetylcholinesterase” debase it. They are produced in the spinal cord.
Biogenic Amines are Amino Acid Tyrosine based. Catecholamines such as dopamine, norepinephrine, epinephrine, and Indolamines, they are allocated in the brain, they are responsible for emotions, body clock regulatory, and excitation behaviours.
Amino acid compound neurotransmitters such as Glutamate and Gama-aminobutyric acid (GABA). Glutamate relates to promotion of excitement, they work in the moderation of soreness, and increment of Enkephalin activity in women in labour.
