Title: Anatomy and physiology
Description: Talks about ALD, the nervous system. It's system dysfunctions, it's impulses and reflexes, nerve tissues, and the Intro to nerve tissue. Questions involving what cells are in the nervous tissue, what causes dysfunctions, etc. this is a study guide to an actual test that was given from the instructor.

Unit 6 Review Worksheet
* Review worksheets are intended to give you an idea of what information you will be tested on
from this unit and to give additional practice on the types of questions that will be on the test
...
Nervous System Intro
1
...
The main body system of control and communication
...
Every thought, behavior, emotion
from its activity
...
A means of a master control / communication system communication
...
Rapid, specific electric pulse resulted in an almost immediate response
...
List and explain the three functions of the Nervous System
...
1
...
Integration: the process and interpretation of sensory input, so that the decision about what to
do
...
The motor output: the original stimuli, activation of the muscles, glands
...
What are the two structural classifications of the Nervous System? Describe each one and
the structures it includes
...
The central nervous system (CNS): including the brain and spinal cord, and found in the
dorsal cavity
2
...
What are the parts and functions of the sensory division of the PNS?
1
...
Transmit impulses to the sensory nerve fibers of the central nervous system
from the skin, skeletal muscle, joint and body = ("body") sensory fiber
From the viscera = visceral sensory fiber
3
...
What are the parts and functions of the motor division of the PNS?
1
...
Carries impulses from the CNS to organs, muscles, & glands
3
...
Describe the somatic and autonomic divisions of the motor division of the PNS
...
What are the two types of cells in nervous tissue?
1
...
Neurons
8
...
List the major differences between supporting cells in the CNS and neurons
...
The supporting cells look like neurons, but they can’t transmit nerve impulses
2
...
What supporting cells forms myelin sheaths around the neurons of the CNS? The PNS?
1
...
In the PNS: Schwann cells and Satellite cells
11
...
Highly specialized cells that transmit messages from one part of the body to another
2
...
Which type of nerve fiber receives? How many of these fibers does a neuron have?
1
...
Processes that conduct impulses toward the cell body
3
...
Which type of nerve fiber sends? How many of these fibers does a neuron have?
1
...
Processes that generate impulses and conduct them away from the body
3
...
What is the myelin sheath made out of? List its two functions
...
Most axons are covered with a fatty material called myelin
2
...
two functions: Protects and insulates the fibers
4
...
What’s the difference between white matter and grey matter in the Nervous System?
1
...
Grey matter in the brain = unmyelinated fibers
* Be able to identify the following structures at a synapse: synaptic cleft, neurotransmitters,
vesicles, receptors
16
...
1
...
Motor (efferent) neurons carrying impulses from the CNS to muscles, glands, organs, etc
...
Interneurons (assocation) – connect the motor and sensory organs
...
List and explain the two major functional properties of neurons
...
Irritability = the ability to respond to a stimulus and convert it into a nerve impulse
2
...
Explain what happens during each of the steps of irritability – polarization, depolarization,
repolarization
...
The unit is now more positive and depolarization
2
...
When not
under a pulse nerve has a negative charge, it's around
...
The film once again become the polarization repolarization
19
...
Why do your fingers feel numb after holding ice and why does your foot “fall asleep” if you
sit on it?
Because your fingers get cold and when your fingers get cold nerves in your fingers slowly shut
down that's why ppl get frost bite
21
...
Once the signal reaches
the end of an axon, which is at the end of a neuron, a neurotransmitter is released and the
process repeats
...
Explain what happens at the synapse to continue an impulse from one neuron to another
...
When a nerve impulse to the axon terminal, it triggers the release of neurotransmitter
2
...
If there is sufficient neurotransmitter known, depolarization of the neuron will happen in the
future
23
...
The easy type of communication between neurons
2
...
Occur over neural pathways called reflex arcs
24
...
Autonomic reflexes: 1
...
2
...
Secretion of saliva and changes in size of pupils
...
Also regulate such body functions as
digestion, elimination, blood pressure, & sweating
somatic reflexes: 1
...
2
...
Quickly pulling
your hand away from a hot object
25
...

What is a spinal reflex?
Some reflexes don’t need the brain and can go to the spinal cord and back spinal reflexes
Central Nervous System
* Be able to identify the following structures of the brain: Cerebral hemisphere, Frontal lobe,
Parietal lobe, Temporal lobe, Occipital lobe, Diencephalon, Brain Stem, Midbrain, Pons, Medulla
Oblongata, Cerebellum, Corpus Callosum, Cerebral Cortex
27
...

...
Diencephalon
...
Brainstem; 4
...
What are the three surface features of the cerebral hemispheres and what do they look like?
1
...
Sulci = grooves
3
...
What is the white matter in the cerebral hemispheres called? The white matter? What does
each do?
1
...
White matter = corpus callosum Inner layer that connects hemispheres
30
...
Basal nuclei Help regulate voluntary motor activities by modifying instructions sent to the
skeletal muscles
* Be able to identify the following functional areas of the brain: Somatic sensory area, Primary
motor area, Visual area, Olfactory area, Auditory area, Broca’s area, Speech area, Higher
intellectual reasoning, Memory

1
...
Treated: Often requires removing part of the skull
40
...
Occur when blood circulation to a brain area is blocked by a clot or ruptured vessel

Everything seems to have something to do with the brain cell’s inability to control calcium
entry
44
...
Myelin sheaths around neurons are gradually destroyed and converted to
hardened sheaths called scleroses
2
...
A deficit in the neurotransmitter dopamine prevents basal nuclei from
regulating voluntary motor activities
45
