Dakota Whitson Mr.Baker Psychology hour 4 April 14‚ 2016 Why Is The Brain So Fragile? In the human body the brain is one of the main organs. It helps the body run and work properly. But‚ what happens if the brain stops working properly? It would affect the whole body. All the systems that the brain is in charge of would stop or not work well. If the brain stopped working properly the central nervous system‚ the limbic system‚ and the brain itself can be in danger. The central nervous system is

Thesis Statement Multiple Sclerosis is mainly an inflammatory disorder of the brain and spinal cord in which central lymphocytic permeation leads to harm of the myelin scabbard and axons. Initially‚ inflammation is temporary and re-myelination occurs but is not long-lasting. Hence‚ the early course of disease is characterized by occurrences of neurological dysfunction that usually recover. However‚ over time the pathological alterations start to take over by widespread microglia activation

Human Sensory Systems Objectives · Describe how sensory receptors communicate to the central nervous system. · Describe receptors that detect temperature‚ pain‚ touch and pressure‚ muscle length and tension‚ and blood pressure. · Describe the nature of vision in terms of its stimulus on the function of rod and cone cells. Introduction The function of the brain is to convey messages to different parts of the body. Messages are conveyed from a nerve cell to another nerve cell‚ muscle cell

which only one protoplasmic process (neurite) extends from the cell body. Most neurons are multipolar‚ generating several dendrites and an axon. Unipolar neurons that begin as bipolar neurons during development are known as pseudounipolar neurons. Multipolar A multipolar neuron (or multipolar neurone) is a type of neuron that possesses a single (usually long) axon and many dendrites‚ allowing for the integration of a great deal of information from other neurons. These dendritic branches can also emerge

1. Human Nervous System- the part of a body that coordinates its voluntary and involuntary actions and transmits signals between different parts of its body. Mostly‚ it consists of two main parts‚ the central nervous system (CNS) and the peripheral nervous system (PNS). 2. Central Nervous System- the processing center for the nervous system. It receives information from and sends information to the peripheral nervous system. The two main organs of the CNS are the brain and spinal cord. The brain

A football player kicking a football is an example of a gross muscular skeletal muscle coordinating together to display the live-action potential of the chemistry between the functions of the nervous‚ muscular‚ and the skeletal system. For these actions to take place‚ the skeletal system must first be established and erected along with the cartilage‚ ligaments‚ and tendons attaching bones‚ muscle to bones‚ and articulation for movements.
