What is the master controlling and communicating system of the body?
The endocrine system
The nervous system
The muscular system
The respiratory system
This is when the nervous system uses its sensory receptors to monitor the changes occurring both inside and outside the body.
Input
Integration
Output
This is when the nervous system processes and interprets sensory information and determines what should be done at that moment.
Input
Integration
Output
This is when the nervous system activates effector organs (muscles and glands) to carry out a response.

Which branch of the nervous system contains the brain and spinal cord?
Peripheral NS
Sympathetic NS
Autonomic NS
Central NS
Which branch of the nervous system consists mainly of nerves that extend from the brain and spinal cord, as well as ganglia?
Central NS
Peripheral NS
Parasympathetic NS
Autonomic NS
How many neuroglial (or glial) cells are there in the CENTRAL nervous system?
2
4
6
8
These types of glial cells are in the CNS. They connect neurons to capillaries and are also used as support. They control the chemical environment around the neuron and help repair if it's injured.
Oligodendrocytes
Ependymal
Astrocytes
Microglial
These types of glial cells are in the CNS. They have small "thorny" processes for defense and protection of the neuron.
Astrocytes
Microglial
Oligodendrocytes
Ependymal
These types of glial cells are found in the CNS. They are responsible for forming and circulating cerebrospinal fluid. They have cilia on their surface to help move it through the system.
Ependymal
Oligodendrocytes
Microglial
Astrocytes
These types of glial cells are in the CNS. They are responsible for myelin sheathing, and can covering many cells at once.
Ependymal
Astrocytes
Oligodendrocytes
Microglial
Glial cells found in the PNS. They function the same way astrocytes do in the CNS; for support.
Schwann cells
Satellite cells
Oligodendrocytes
Microglial
These types of glial cells are in the PNS, and are known for their myelin sheathing. They can only wrap a small section of the axon at a time.
Astrocytes
Oligodendrocytes
Satellite cells
Schwann cells

What characteristic of the neuron is this?
Given good nutrition, neurons can function optimally for a lifetime.
Longevity
Amitotic
High metabolic rate
What characteristic of the neuron is this?
As neurons assume their roles as communicating links of the nervous system, they lose their ability to divide.
Longevity
Amitotic
High metabolic rate
What characteristic of the neuron is this?
They need continuous and abundant supplies of oxygen and glucose. They use about 20% of the body's energy, and cannot survive more than a few minutes without oxygen.
Longevity
Amitotic
High metabolic rate
The cell body of the neuron has mostly which organelle (for synthesizing proteins?)
Golgi apparatus
Smooth ER
Rough ER
Lysosomes
Anterograde means towards the cell body.
True
False
Retrograde means
Away from the cell body
Towards the cell body
Running parallel to the cell body
Not moving to or from the cell body
Where is this type of neuron found in the body?
In the sensory organs (such as the retina of the eye)
Mostly in the CNS
In the skin
None of the above
Where is this type of neuron found?
In the sensory organs (such as the retina of the eye or the olfactory mucosa)
In the skin
In the CNS
None of the above
Where can you find this neuron in the body?
In the sensory organs (retina of the eye or olfactory mucosa)
As interneurons (between sensory and motor neurons in the neural pathway)
As sensory neurons
None of the above
The resting membrane potential of a neuron is approximately...
-70 mV
-90 mV
-55 mV
+30 mV
