Ayyyeeee
The study of the nervous system.
Neurology
Actual nerve cells of the body are called ___.
Neurons
Chemicals that are released in the synapse that help get messages from one neuron to another.
Neurotransmitter
When an emergency is over, this division of the ANS kicks in to slow down your body's metabolic activities.
Parasympathetic
Largest part of the brain.
Cerebrum
The left and right hemisphere's of the brain communicate with one another through a mass of nerve fibers called the ____.
Corpus Collosum
Which lobe is associated with vision and color perception?
Occipital Lobe
The junction where an axon from one neuron connects to the dendrites of another neuron.
Synapse
Carry nerve impulses away from the body.
Axons
What makes up the CNS?
Brain and spinal cord
A typical adult brain weighs how much on average?
3 lbs
These cells support and insulate nerve tissue.
Glial Cells
This philosophy states that a person's actions can be completely explained as responses to particular stimuli.
Behaviorism
Branching extensions from the cell that receive impulses from other neurons and send them to the cell body.
Dendrites
These neurons are found ONLY in the CNS and are responsible for information processing by the brain and spinal cord.
Interneurons
These fibers carry impuslses from light, taste, sound, touch, and pain from other parts of the body to the brain and spinal cord for analysis.
Sensory Nerve Fibers
Happy / feel good neurotransmitter.
Dopamine
The _____ matter of the brain and spinal cord is composed largely of axons.
White Matter
Located behind the frontal lobe; analyze senses to allow us to feel temperature, pressure, and pain.
Parietal Lobe
Located at the uppermost end of the brain stem; acts as a swichboard, routing activation signals from the neurons to the appropriate areas of the cerebral cortex.
Thalamus
The ____ nervous system is responsible for functions you can control. EX: you're runnning and see a patch of ice - this system kicks in so you know to move out of the way so you don't slip.
Somatic Nervous System
This structure assists the medulla oblongata in regulating breathing.
Pons
Disease of brain and spinal cord; typically affects adults and occurs when the body's immune system attacks the glial cells that provide myelin sheaths for nerve cell axons.
Multiple Sclerosis (MS)
Where is the occipital lobe located?
Back of the brain
These cells are responsible for prodcuing layers of myelin sheathing that acts like the insulation on an electrical wire.
Schwann Cells
