Cervical Nerves


We just learned about the Dorsal Root.

The spinal nerves that that go up and down your spinal cord are split up by what section they are in.
The top section of spinal nerves between your head and your shoulders are called the cervical nerves.
There are 8 cervical spinal nerves, called C1, C2, C3, C4, C5, C6, C7, C8.

These nerves help control the muscles in your neck and your tongue.

Dorsal Root


We just learned about the anterior roots that are on the front part of the spinal nerve.

The nerves that come out the back side of the spinal nerve are the Dorsal Roots.
Dorsal means the top or backside, like a dorsal fin of the dolphin.

Anterior Roots


We just learned about the part in the middle of the spinal cord called the Grey Column.

Another part of the nervous system in the spinal column is the Anterior Roots or ventral roots.

These are the nerves that come out of the spinal cord on the anterior, or front side of the spinal cord.
They really are coming out the side of spinal cord, but on the front part of the side.

Grey Column


We just learned about the Spinal Nerve.

Another part of the central nervous system is the Grey Column.
This is inside the spinal column, and is made up of grey matter.

Spinal Nerve


We just learned about the Foramen Magnum.

A while back we learned about the bones in your back called the vertebrae.
These are the bones that help protect your spinal cord.
Inside each of these bones are some nerves called Spinal Nerves.

The main spinal cord goes down the middle, and the spinal nerves come out from the sides and go out to all parts of the body.

Foramen Magnum


We just learned about the Spinal Cord.

Where the spinal cord connects to the brain, there is a hole in the bottom of the skull.
That hole is called the Foramen Magnum which means Great Hole.

Spinal Cord


We just learned about all the parts of the Brain,
like the forebrain, midbrain, hindbrain and limbic system.

The other main part of the Central Nervous System is the spinal cord.

This is like a big thick bundle of wires that goes down your neck, and down your back.
It sends and receives information from every part of your body to your brain.

Limbic System


We just learned about Midbrain.

Another part of the brain is the limbic system.

This part of the brain helps control the movement, feelings, learning and memories.

Midbrain


We just learned about the Forebrain.

Another part of the brain is called the midbrain.

This part of the brain helps control your seeing, hearing, movement, sleeping and how hot or cold you feel.

Forebrain


We just learned about the diancephalon.

The diencephalon, along with the cerebrum make up the forebrain. This is the large part of the brain that takes up most of the skull.

The forebrain is also known as the prosencephalon.

Diancephalon


We just learned about the hindbrain.

Another part of the brain is the diancephalon.

We learned before about the thalamus, hypothalamus and subthalamus.
All of those parts together are what make up the diancephalon.

Hindbrain


We just learned about the medulla oblongata.

The medulla oblongata, together with the pons and cerebellum make up what is called the hindbrain or the rhombencephalon.

Medulla Oblongata


We just learned about the part of the brain called the pons.

Another part of the brain is called the medulla oblongata.

This part of the brain helps control your heart pumping, your body using up oxygen, and how you swallow, cough, sneeze or throwup.

Pons


We just learned about cerebellum.

Another part of the brain is called the pons.

This part of the brain is used to control sleep, breathing, balance and even dreams.

Cerebellum


We just learned about the subthalamus.

Another part of the brain is the cerebellum.

This part of the brain is mostly used to control the movements of the body.

Subthalamus


We just learned about the epithalamus.

Another part of the brain is called the subthalamus.

This part of the brain helps move the arms and legs.

Epithalamus


We just learned about Hypothalamus.

Another part of the brain is the epithalamus.

This part of the brain helps control our sleep and our feelings.

Hypothalamus


We just learned about the part of the brain called the thalamus.

Another part of the brain is the hypothalamus.

Just like the thalamus, this is part of the forebrain, and it helps control your body temperature, your hunger, sleep and even what you do when you are afraid.

Thalamus


We just learned about the Occipital Lobe in the Cerebrum.

Another part of the brain by the cerebrum is called the Thalamus.

This part of the brain helps send messages back and forth from the cerebrum to all parts of the body like your eyes and ears.

It also helps you stay awake when you want or fall asleep when you're tired.

Occipital Lobe


We just learned about Temporal Lobe.

Another part of the brain is the Occipital Lobe.

This part of the brain is used to take the things you see and turn them into pictures that your brain can understand.
