PHYSIOLOGY
QUESTION 01
The human nervous system is capable of a wide range of functions. What is the basic unit of the nervous system?
Neuron
Axon
Dendrite
QUESTION 02
Which part of the neuron is involved in sending an impulse to the synapse area or an effector?
Axon
Dendrite
Soma
QUESTION 03
Neurons that only travel from the body to the brain are called
sensory neurons
interneurons
motor neurons
QUESTION 04
Impulses that are going toward the CNS are called __________ and impulses going away from the CNS are called __________.
afferent; efferent
motor; sensory
efferent; afferent
QUESTION 05
The nervous system is composed of the ----------, ---------- and ----------.
brain, spinal cord, nerves
eye, pancreas, veins
heart, brain, kidneys
QUESTION 06
Maintain stable internal condition example includes fever and vomiting.
Homeostasis
Epidermis
Telekinesis
QUESTION 07
__________ neuron carry messages to the central nervous system.
Sensory
Motor
Response
QUESTION 08
Automatic life functions such as heartbeat and breathing are centred in the:
Limbic system
Cerebellum
Brain stem
QUESTION 09
The part of the neuron that takes in and receives messages is called the
synapse
axon
dendrite
QUESTION 10
Any message that is sent by the body or the brain using neurons is called an
stimulus
synapse
impulse
QUESTION 11
Whose job is it to carry nerve impulses away from a cell body in a neuron?
Axons
Dendrites
Spinal cord
QUESTION 12
Once a gated channel is open, and positive ions will enter through the channels to get inside the neuron. Which of the following can cause the gated channels to open?
Stimulus
Dendrite
Synapse
QUESTION 13
Which of the following statements is true?
An action potential occurs if there are more sodium ions than potassium ions inside an axon.
An action potential occurs if the membrane goes from +30 mV to –70 mV.
An action potential occurs if there are more potassium ions than sodium ions inside an axon.
QUESTION 14
What is the function of the nervous system?
Send and receive messages to respond to a change in an organism-environment
Brings oxygen into the body
Moves body part
QUESTION 15
Since depolarization results in positive ions entering the neuron, there will be a voltage change. Which of the following correctly depicts the voltage value going from a resting neuron to a depolarized neuron?
+10 mV to +30 mV
–70 mV to 0 mV
+30 mV to –70 mV
QUESTION 16
When discussing a neuron's activity, we discuss graded potentials and action potentials. A graded potential arises in all of the following EXCEPT
somas
axons
dendrites
QUESTION 17
Which of the following would be the best and most accurate way of describing an action potential?
If there are enough stimuli, the sodium ion channels (gates) will open simultaneously within the axon.
If there are enough stimuli, the sodium ion changes (gates) will open in succession down an axon.
If there are enough stimuli, the sodium ion channels (gates) will open only in the dendrite area. There have to be additional stimuli to get the channels to open in the axon area.
QUESTION 18
Hyperpolarization of a neuron occurs when the inside becomes more negatively charged than at a potential resting value. Which of the following will NOT cause hyperpolarization?
Massive entrance of sodium ions into the axon
Massive entrance of chloride ions into the axon
Massive entrance of sodium ions into the axon
QUESTION 19
Bundle of wire-like nerves threaded through the backbones, through which electrical messages travel between the brain and body.
Neuron
Nerves
Spinal cord
QUESTION 20
Which of the following statements is FALSE?
If the stimulus reaches the threshold level, depolarization will occur.
If the stimulus does not reach the threshold level, depolarization will not occur.
If the stimulus almost reaches the threshold level, depolarization will only occur halfway down the axon.
