GALEN A&P NU-110 EXAM 4 (RECENT EXAM)
FULLY SOLVED & UPDATED 2026 MOST COMPLETE
(2026) (LATEST UPDATE 2026) UPDATE!!
Polarization State.
is the resting State. The inside is more negative. Potassium is being
moved out. and the inside of the cell becomes more negative.
Depolarization
Is a stimulated neuron. The inside of the cell becomes more positive.
There is allot of Sodium to come into the cell.
Repolarization
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.
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)
are schwann cells and oligodendrocytes.
Schwann cell is located in the
peripheral nervous system. makes myelin
In a myelinated nerve
the nerve impulse jumps from node to node.
Saltatory Conduction
it is the jumping of the nerve impulse in the myelinated nerve.
,Myelination increases
the speed of the nerve impulse.
Gray matter
does not have any myelination.
Corpus Collosum
is the only bridge from the right and left side of the brain.
Synapse or Synaptic Cleft
is the space between two neurons. Neurons do not physically touch.
Neurotransmitter
chemical substances contained in the vesicles.
Synapse step 1
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
is exocytosis of the chemical
Synapse Step 3
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
by enzymes and repute transporter.
Reuptake Transporter/pumps
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
, it is like paceman. It destroys the neurotransmitter that has been
released.
4 major parts of the brain
Cerebrum, Diencephalon, Brain Stem, Cerebellum
4 major lobes of the Cerebrum
Frontal, Parietal, Temporal, occipital
Frontal Lobe
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
Parietal
primary somatosensory(sensory information from muscles) from skin an
muscle, taste, speech, reading
Temporal
Hearing, speech, smell, taste. Wernicke's area
Brocas Area
is the motor speech area. Makes you physically able to talk. If had a
stroke here could not physically talk, can write it down. Left frontal lobe
Wernicke's Area
translation of thought into words. Cognitive speech area. In the left
temporal. Can talk just fine, but what you say does not make sense at all.
Or can not understand what people are saying
Occipital
vision
Diencephalon
is the thalamus and the hypothalamus
