The Central Nervous System (CNS) correct answers Includes the brain and the spinal cord
The Peripheral Nervous System (PNS) correct answers includes the nerves that connect the
Central Nervous system with the rest of the body
2 parts of nervous tissue correct answers Glia Cells, and neurons.
Glia cell correct answers are support cells of the brain
astrocytes, microglia, oligodendrocytes
Astrocytes correct answers makes the blood brain barrier. Connects to blood vessels and acts as
the gate keeper. Does allot with metabolism, mostly of medication
Microglia correct answers immune cells of the brain. Migrate to the area of injury, it covers it
and cleans it up. It does not have allot of T or B cells.
Oligodendrocytes correct answers secretes allot of myelin. It is important for the neuron.
Actually wraps around portions of the neuron.
Myelin correct answers increases the speed of the neuron. It is the white matter of the brain and
the spinal cord.
Neurons and Glia can grow back correct answers but they grow back very slowly.
neuron information only travels correct answers in one direction. That way there is no traffic
jams or mixed signals.
,Dendrites correct answers where the information comes in to the neuron
Cell Body correct answers houses the nucleus and other cell structures. Receives signal from the
dendrites.
Axon correct answers gets information from the cell body
Axon Terminals correct answers Get information from the axon. Is where we release all of the
neuron transmitters.
Myelin correct answers Not all neurons have ______ but those that do move information quickly
Afferent Neurons correct answers are sensory neurons. Carries information to the Central
nervous system.
Interneurons correct answers makes connections within the central nervous system.
Efferent Neurons. correct answers Motor neurons. Carry information away from the Central
nervous system and towards the periphery.
Neurons and Glia are all correct answers intermingled together
Action Potential or Nerve impulse correct answers is the electrical signal. Can only happen in the
neuron
Neuron can only be in one of 3 states correct answers Polarization, Depolarization,
Repolarization
,Polarization State. correct answers is the resting State. The inside is more negative. Potassium is
being moved out. and the inside of the cell becomes more negative.
Depolarization correct answers Is a stimulated neuron. The inside of the cell becomes more
positive. There is allot of Sodium to come into the cell.
Repolarization correct answers returns to resting. Charge goes back to negative inside. Puts all of
the ions back to where they are supposed to be. So potassium moves out. Back to negative charge
on the inside.
Refectory Period. correct answers Cell is not able to respond to another action potential until
repolarization is complete and everything is back to where it is supposed to be.
Make myelin (2 cells) correct answers are schwann cells and oligodendrocytes.
Schwann cell is located in the correct answers peripheral nervous system. makes myelin
In a myelinated nerve correct answers the nerve impulse jumps from node to node.
Saltatory Conduction correct answers it is the jumping of the nerve impulse in the myelinated
nerve.
Myelination increases correct answers the speed of the nerve impulse.
Gray matter correct answers does not have any myelination.
Corpus Collosum correct answers is the only bridge from the right and left side of the brain.
, Synapse or Synaptic Cleft correct answers is the space between two neurons. Neurons do not
physically touch.
Neurotransmitter correct answers chemical substances contained in the vesicles.
Synapse step 1 correct answers is that the nerve signal has to travel down the signal. When it gets
to the end it goes with the vesicle and moves to the end.
Synapse Step 2 correct answers is exocytosis of the chemical
Synapse Step 3 correct answers is the chemical binds with the receptor in the new nerve. To start
to process over again in a different neuron
Inactivation of the neurotransmitter can be done correct answers by enzymes and repute
transporter.
Reuptake Transporter/pumps correct answers are more in the axon that sucks the
neurotransmitter back into the neuron and use it the next time. It recycles it
The Enzyme that stops the neurotransmitter correct answers it is like paceman. It destroys the
neurotransmitter that has been released.
4 major parts of the brain correct answers Cerebrum, Diencephalon, Brain Stem, Cerebellum
4 major lobes of the Cerebrum correct answers Frontal, Parietal, Temporal, occipital
Frontal Lobe correct answers It the primary motor cortex. Personality emotions and memory.
This is the movement area. Still grows till 25. last of the system to fully develop. Executive
function/decision making skills
The Central Nervous System (CNS) correct answers Includes the brain and the spinal cord
The Peripheral Nervous System (PNS) correct answers includes the nerves that connect the
Central Nervous system with the rest of the body
