DAANCE module 1: Basic Sciences
1)What is the role of the central nervous system?
2)What are the 3 subdivisions of the central nervous system? – \u2714\u27141) 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? – \u2714\u27141) 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?<\/p>\n\n\n\n
3) What is the wave of polarization?
4) Explain repolarization.
5) How does this relate to local anesthetics? – \u2714\u27141) 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? – \u2714\u27141) 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<\/p>\n\n\n\n
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) – \u2714\u27141) 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) – \u2714\u27141) 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? – \u2714\u27141) 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.<\/p>\n\n\n\n
