Central nervous system cancers essay

Touch stimulation from the skin is ultimately sent to the parietal lobe. The nerve impulses are carried over this small gap between a pair of neurons by means of a chemical substance called neurotransmitter substance.

Of these 12 pairs, the olfactory and optic nerves arise from the forebrain and are considered part of the central nervous system: The receptor in a sense organ is in touch with the dendrites of sensory neuron.

There is always a very, very small gap between the two neurons where they join. Central nervous system diseases Tumors can affect the CNS.

The central nervous system has been thoroughly studied by anatomists and physiologists, but it still holds many secrets; it controls our thoughts, movements, emotions, and desires. The neurons carry messages in the form of electrical signals called electrical impulses or nerve impulses.

Its job is to control and coordinate the parts of our body so that they work together, doing their job at the right time. Neurons contain the same basic parts as any other animal cell but their structure is specially adapted to be able to carry messages over large distances in the body quickly.

The retina, optic nerve, olfactory nerves, and olfactory epithelium are sometimes considered to be part of the CNS alongside the brain and spinal cord. The brain is the central control module of the body and coordinates activity.

Olfactory nerves cranial nerve I: We can now say that nervous system is made of special cells called neurons. However, many higher functions — reasoning, problem-solving, creativity — involve different areas working together in networks.

All about the central nervous system

The brain is protected by the skull the cranial cavity and the spinal cord travels from the back of the brain, down the center of the spine, stopping in the lumbar region of the lower back.

Below are the major causes of disorders that affect the CNS: From the brainstem, where the spinal cord meets the brain, 31 spinal nerves enter the cord.

The brain is only required to stop and start the process, or make changes if, for instance, an object appears in your path. The CNS, however, does not have this ability.

Let A be a sensory neuron which is directly connected to the receptor. A neuron or nerve cell has three components: Any two neurons in the nervous system do not join to one another completely. The spinal cord, running almost the full length of the back, carries information between the brain and body, but also carries out other tasks.Types of central nervous system cancers You’ll see lots of names of brain and spinal cord cancers.
