How many portions are within the nervous system?: 2
What are the two main portions in the nervous system?: Central Nervous System and
Peripheral Nervous System
What are the two main parts of the Central Nervous System (CNS)?: The brain and
spinal cord (extension cord of the brain)
Brain: Is the controlling organ of the body
Cerebrum: largest part of the brain; responsible for higher thought processes
What are the four lobes of the brain?: frontal, parietal, temporal, occipital
How does the brain control the activities on the body?: The brain control activities on the
opposite side of the body.
Cerebellum: Coordinates body movements
,Brain stem: Control body functions necessary for life, including cardiac and respiratory functions and regulation
of consciousness.
What are the three areas of the Brain stem?: 1. midbrain (first)
pons (second)
medulla oblongata (third)
11. Midbrain: 1. Located between the pons and diencephalon (thalamus and hypothalamus)
Short section of brainstem
Contains grey matter that serves as a reflex center
12. Pons: 1. Rounded bulge
Relays info between the medulla oblongata and the cerebrum
Nuclei of the pons relay sensory info between peripheral nerves and higher brain centers
13. Medulla oblongata: 1. Inferior part of the brain stem
Cardiac center adjusts force and rate of heart contraction
Regulates blood pressure (BP) by acting on smooth muscle in the walls of peripheral arterioles
Respiratory centers control the depth and rhythm of breathing
Spinal cord: Is an extension of the brain stem
,Spinal cord funtions: 1. Transmits messages between the brain and the body
Encased within the spinal canal (hole within vertebrae)
Cerebrospinal fluid (CSF) cushions the brain and spinal cord
Peripheral Nervous System: Nerves outside the brain and spinal cord that link the CNS to various
organs of the body
, What are the two divisions of the peripheral nervous system?: Somatic nervous
system (voluntary)
Autonomis nervous system (Involuntary)
Somatic nervous system (voluntary): Allows for activities such as walking, talking, and writing
Autonomic nervous system (involuntary): Digestion, dilation, and constriction of blood vessels,
and sweating
What are the two split within the autonomic nervous system?: Sympathetic nervous
system
Parasympathetic nervous system
sympathetic nervous system: which is responsible for the fight-or flight response
parasympathetic nervous system: the division of the autonomic nervous system that calms the
body, conserving its energy. Rest and digest. (which slows down the body)
What does the sensory nerves do?: It carry information from the body to the CNS.
What does the motor nerves do?: It carry information from the brain to muscles/rest of the body.
