Ch 5 The Nervous System – Neurology and Psychiatry Flashcards
The nervous system serves as the body’s
communications network, coordinating data reception with appropriate reaction.
Nervous system is composed of two parts:
the peripheral nervous system and central nervous system.
The peripheral nervous system collects
data
Peripheral nervous system receives information such as
temperature, pain, light, and pressure from its surroundings
As quickly as peripheral nervous system receives input it transmits it to an
analytic center via special conduits known as nerves
The unified collection of cells in the brain and spine are known as the
central nervous system
The central nervous system processes the details and formulates a
response
Commands are directed back to the appropriate body parts via
nerves
brain and the collecting/acting nerves make up your
nervous system
The nerves that send and receive signals from the brain are collectively known as the
peripheral nervous system
Brain and Spinal Cord are called the
central nervous system
The brain has several sections
(lobes) and is divided in two halves (hemispheres)
Largest portion of your brain is the
cerebrum
Under the cerebrum is the
cerebellum (controls things like coordination of movements)
central nervous system is fragile and needs a protective membrane
meninges
central nervous systems tough outer layer is known as the
dura
root for Brain
cerebr/o , encephal/o
root for cerebellum
cerebell/o
the encephalo root comes from en(inside) and cephalus(head) and means
“the stuff inside your head”
cerbell/o is brain with a diminutive suffix that means
“little brain” (little version of the brain)
