  • Growth In Neurons In The Spinal Cord
    853 words
    Spinal Cord Regeneration Spinal cord injury can occur in many ways ranging from gunshot wounds, stab wounds and also bone displacement. These circumstances can lead to the death of neurons, and the remyelination of axons which causes some loss and damage to neurons. As Hudgins (1998) reports after a primary injury such as above, secondary injury occurs 30 minutes after and also that secondary injury is when the most critical damage occurs. This is when there is hemorrhaging in the gray matter of...
  • Main Parts Of The Nervous System
    454 words
    Nervous System The two types of the nervous system are the Central nervous system and the peripheral nervous system. They are responsible for integrating, processing, and coordinating Sensory data and motor commands the central nervous system, which interprets sensory input and carry information to maintain homeostasis. CNS can^aEURTMt be regenerate because a CNS consists of the spinal cord that mean if it^aEURTMs break the spinal cord is break also. The peripheral nervous system consists of the...
  • Responses In Animal Behaviour
    2,141 words
    The role of the nervous system in behaviour. Introduction. The nervous system is the fundamental control system for all behaviour. It is responsible for receiving incoming information from the surroundings, collating and processing it and then causing a relevant behavioural response. For an animal to survive it must be able to respond differing internal as well as external states and parts of the body must be able to act in a co-ordinated fashion to illicit behaviours that are favourable to the ...

  • Study Of Nitric Oxide
    1,278 words
    Expansion on the Recent Discoveries Concerning Nitric Oxide as presented by Dr. Jack R. Lancaster Nitric Oxide, or NO, its chemical representation, was until recently not considered to be of any benefit to the life processes of animals, much less human beings. However, studies have proven that this simple compound had an abundance of uses in the body, ranging from the nervous system to the reproductive system. Its many uses are still being explored, and it is hoped that it can play an active rol...
  • Neurotransmitter Acid
    1,681 words
    Neurotransmitters Neurotransmitters are chemicals made by neurons and used by them to transmit signals to the other neurons or non-neuronal cells (e. g., skeletal muscle; myocardium, pineal glandular cells) that they innervate. The neurotransmitters produce their effects by being released into synapses when their neuron of origin fires (i. e., becomes depolarized) and then attaching to receptors in the membrane of the post-synaptic cells. This causes changes in the fluxes of particular ions acro...
  • Message To The Cell Body
    613 words
    The nervous system is composed of two main cell types the neurons and glial cells. Neurons transmit nerve messages and glial cells are in direct contact with neurons and often surround them. The basic function of the nervous system is as follow. They receive sensory input from internal and external environment, the integrate the input a they respond to stimuli. The nervous system also consists of senses. These senses are: pain, vision, taste, smell, and hearing. The neuron is the functional unit...
