Multiple Choice
If you are having trouble with your BALANCE and COORDINATION, which part of your brain should be checked?
4
Multiple Choice
This part of the brain is the center of conscious thought. It controls our voluntary muscle movements like running and talking as well as our senses (hearing and tasting).

Nerve Cell
Nerve cells carry messages one way. Most nerve cells have a special cell that wraps around them that insulates them and helps the neuron to carry the message up to 250 mph! (300 meters/second)
The cell responsible for insulating the CNS neurons is known as the oligodendrocyte.
Cells that have the oligodendrocytes wrapped around them are called white neurons and they make up the white matter of the CNS

Brain Ventricles!
There are four ventricles of the brain: two lateral that meet on the midline, here the third ventricle can be found, and the fourth just beneath the third.
13
Spinal Cord
The spinal cord is much like an interstate that connects the brain to the body. It receives sensory input from the body and delivers motor output to specific areas of the body.
Nerve pathways are ONE WAY. There has to be pathways going to the brain (sensory) and separate pathways coming from the brain (motor).
14
Neuron Structure
1. Dendrites: receive the message or stimuli When the proper stimuli opens the channels, Na+ enters and can cause the neuron to ‘fire’ or carry the message. Send message to the Cell body
2. Cell Body: the message travels through the cell body to the axon hillock (#3) The cell body is also known as the Perikaryon (Peri=around and karyo=nucleus. In the cell body, there are lots and lots of rough ER and ribosomes.
15
Neuron Structure
3. Axon of Hillock : If the message is strong enough and Hillock: triggers the axon hillock
4. Axon: Axons carry messages away from the cell body/axon hillock.
5. Axon Branches: The branches carry the message down to the bouton (#6).
6. Boutons: The boutons release a neurotransmitter (NT) that will stimulate the next neuron or muscle.
16
Neuron Structure
7. Synaptic Vesicles: These small vacuoles contain the NT. They have traveled from the cell body down the axon to the bouton. As the message or nerve impulse enters the bouton, some of the synaptic vesicles bind to the cell membrane and release their NT by exocytosis.
8. Synaptic cleft or Synapse: This is the space between the two neurons or the neuron and muscle.
