What is the role of the Nervous System?
To provide overall control of body function
What are the three subdivisions in the Nervous
System?
Central (CNS), Peripheral (PNS), and Autonomic (ANS)
What is a nerve action potential?
The nerve's threshold of stimulus
What is a synapse?
A junction between two neurons
How do local anesthetics exert their effects?
By interfering with the passage of Na+ ions through the ion
channels and preventing depolarization with slowing or
stopping of movement of the nerve impulse.
How are most of the intravenous, inhalation and local
anesthetic drugs used in OMS utilized in the body?
,Alteration of nerve conduction by modification of the
actions of neurotransmitter substances and/or alteration of
the movement of ions through membrane channels
What is the central nervous system and what does it
consist of?
Overall control center of the body. Consists of the brain
and spinal cord
What are the major components of the brain?
Cerebral Cortex, Core of the Brain, Cerebellum and the
Brainstem
The cerebral cortex is responsible for?
Thought, learning, memory, consciousness, feeling of
sensations such as pain or heat, and the initiation of
muscle movement
What is the purpose of the core of the brain?
It serves as a relay station between sensory inputs from
the periphery of the body to the cerebral cortex.
What is the purpose of the cerebellum?
Coordinating center for both sensory receptors, such as
those for vision and hearing as well as coordination of
movement
, What does the brainstem consist of?
Midbrain, pons, medulla oblongata
What is the purpose of the brainstem?
Contains the important control centers for autonomic
nervous system functions.
What is the reticular formation responsible for?
Maintenance of consciousness or arousal
The medulla contains?
Important centers for the control of blood pressure, heart
rate, respiration and digestion
The peripheral nervous system consists of?
The nerves that carry impulses away from the central
nervous system to the various parts of the body and those
that carry impulses from the periphery back to the CNS.
What are the two components to the peripheral
nervous system?
Cranial nerves and Spinal nerves
What are cranial nerves?
Any of the 12 pairs of nerves connected with the brain;
they are part of the peripheral nervous system
