DAANCE module 1 Basic Sciences 45 Questions with
100% Correct Answers Guaranteed A+
1)What is the role of the central nervous system?
2)What are the 3 subdivisions of the central nervous system? Correct Answer1) To
provide overall control of body function
2) Central Nervous System, Peripheral Nervous System, Autonomic Nervous System
NERVOUS SYSTEM:
1) What are the cells of the nervous system called?
2) What are they responsible for?
3) What is action potential? What happens during this?
4) How is this related to a synapse?
5) What is a synapse?Correct Answer1) Neurons
2) Responsible for conducting nerve impulses within the brain and from one body part to
another
3) The nerves threshold of stimulus. When an impulse reaches the threshold, the
impulse travels along the neuron at a constant rate.
4) When an impulse reaches the end of the neuron, it can pass to another neuron
across a synapse.
5) A junction between two neurons.
DEPOLARIZATION/REPOLARIZATION:
1) Explain depolarization.
2) What substance is often the material moving in and out of the membrane?
3) What is the wave of polarization?
4) Explain repolarization.
5) How does this relate to local anesthetics?Correct Answer1) The outside of a
nerve membrane is positively charged. When those charges move into the membrane,
the outside is left negatively charged.
2) Na+ ions
3) The movement of changing charges during depolarization.
4) After the nerve impulse passes through the nerve, the nerve fibers become
repolarized, or positively charged, again.
5) Local anesthetics interfere with Na+ ions traveling through the ion channels,
preventing depolarization and slowing or stopping the nerve impulses.
SYNAPSES:
1) What is a terminal button?
2) What are pre-synaptic and post-synaptic?
3) What is a synaptic cleft?
4) What substance is this product dependent on?
, 5) What action does this substance have?Correct Answer1) The bulge at the end of
the nerve, that touches the next nerve.
2) The nerve before and after the synapse that is active.
3) The gap between two nerves, which a nerve impulse must 'jump across' to
communicate with the next nerve.
4) Neurotransmitters
5) They enable transmission of the depolarization wave from one nerve onto the
receptor sites of the next.
CENTRAL NERVOUS SYSTEM:
1) What is the central nervous system, and what does it consist of?
2) What are the parts of the CNS? (4 parts)Correct Answer1) It is the overall control
center of the body, consists of the brain and the spinal cord.
2) Cerebral Cortex, Core of the Brain, Cerebellum, and the Brainstem.
CEREBRAL CORTEX:
1) How many parts does it have?
2) What are its main responsibilities? (6 things) Correct Answer1) 2 parts- paired
cerebral hemispheres.
2) Essential functions- thought, learning, memory, consciousness, feeling of sensation
(such as pain or heat), and initiation of muscle movement.
CORE OF THE BRAIN:
1) What is its main purpose?
2) What does one of the core's components do?
3) What can other important structures in the core do? Correct Answer1) Impulses
pass through the core on their way to or from the cerebral cortex.
2) It serves as a relay station between sensory inputs from the periphery of the body to
the cerebral cortex.
3) They play important roles in the body's autonomic (automatic) functions, and
emotions.
CEREBELLUM:
1) What is the purpose?Correct Answer1) It is the coordinating center for both
sensory receptors (vision, hearing) and coordination of movement.
BRAINSTEM:
1) Where is this located?
2) What are the 3 parts of the brainstem?
3) What important control centers does it contain?
4) What else does it contain, and what does this do? Correct Answer1) Between the
brains core and the spinal cord (inferiorly).
2) midbrains, pons, medulla oblongata.
3) Autonomic (automatic) nervous system.
4) Reticular formation, responsible for consciousness or arousal.
