Nervous System

Front 1

What are the 2 systems in the nervous system and what are they?

Back 1

-Central: Brain and spinal cord

-Peripheral:Afferent and Efferent division

Front 2

What is the Afferent and Efferent division?

Back 2

-Afferent: Sensory information that flows to the brain

-Efferent:Motor comands from the brain to muscle or gland

Front 3

What are the 2 systems of the efferent division and what do they do?

Back 3

-Somatic: Skeletal muscle

-Autonomic: divides into parasympathetic and sympathetic.
-effects organs, glands, and smooth muscle

Front 4

What is parasympathetic and sympathetic do?

Back 4

-Parasympathetic: rest and digest

-Sympathetic: fight or flight

Front 5

Whats neural tissue made up of and what do they do?

Back 5

-Neurons: (nerves) responsible for transmitting information

-Neurogilia (gilial0-supporting cells

Front 6

What is the Nissl bodies, axon hillock, perikaryon, dendries and axon in a neuron?

Back 6

-Nissl bodies: elaborate type of rough ER involving metabolism
-Axon Hillock: transition area between soma and axon
-Perikaryon: region around the nucleus
-Dendrites: stimulated by environmental changes or other activies of other cells
-axon: conducts nerve impulses (action potentials) toward synaptic terminals

Front 7

What are the Glial cells of the CNS?

Back 7

-Astrocytes
-Oligodendrocyets
-Microglia
-Ependymal Cells

Front 8

What does Astrocytes do and what kind of cell is it?

Back 8

-a Glial cell
-Maintain blood brain barrier (BBB)
-Create framework for CNS
-perform repairs in damages of neural tissue
-guiding neron development
-controlling the interstitial environment

Front 9

What does oligodendrocytes do and what kind of cell is it?

Back 9

-a Glial Cell
-ties axons together
-create myelin in the CNS

Front 10

What is myelin, white matter and grey matter?

Back 10

Myelin: improves performance (conduction speed)
-White matter: contains myelin
-Grey matter: have unmyelinated axons
