This is my introduction to the brain and spinal cord. I will tell you where they are located and what they do in my own words. Listen and read.
The spinal cord is located on your lower back. It is made out of a big bundle of neuron and the purpose is to allow you to move. It helps you work, sleep and do things in todayís world. The brain controls every thing in the body. It is in the top layer of your skull with jelly mass and has three parts. Thatís the end of the introduction of the spinal cord and brain. One of the parts of the nervous systems is the brain.
The brain belongs to the section of nervous systems called the central nervous system or C.N.S. It is at the top of your head inside your skull. This soft jelly like mass has three parts. These three parts are called the cerebrum, cerebellum, and the medulla or brainstem. The function of the cerebrum is to control voluntary action, which includes speaking, the five senses, movement, memory, and thinking .Thc second major part of the brain is the cerebellum. The cerebellum commands balance coordination and posture. The last major part of the brain is the medulla it is in charge of heartbeat digestion, breathing sleeping and being awake. These are all the involuntary function of the body This part of the brain is the connector between the spinal cord and the cerebrum.
The spinal cord belongs to the C.N.S. It is the most important bones of your lower back and it controls movement and mostly every thing in the body it has nerves. If you do not have a spinal cord you canít move around and go anywhere. You can not work or you cannot do most things normal people do. That is why you need a spinal cord to live in todayís world.
The five senses belong to the Peripheral Nervous System. They are the skin,which is the largest organ in the body,located all over the body. Ears located R/L side of the head above the jaw. Eyes located R/L side of the nose. Nose located at the center of the face between your eyes above the mouth. Tongue located inside your mouth below the nose and above the chin. The function of each of the sense organs are,your nose is for smelling. The tongue is for taste. The skin it lets you feel things. Eyes lets you see things like your eye sight. Ears lets you hear sounds.
The Neuron belongs to the P N S .Neurons are located every where in your body. The five parts are the cell body and the dendrites,neurontransmitter and nucleus and axon.The cellbody is the main part of the cell. Dendrite is the receiving part of the neuron. Neurotransmitter Ė message carrying chemistry. Nucleus is the brain of the neuron. Axon carries the message to the next neuron, which controls all of the nerves.
In conclusion the nervous system is the controling part of the body. The neurons also has two sections and four parts. The two sections are the central nevous system is the brain, spinal cord, neurons, and the five senses. That is the closing of the nervous system.
