Brain
Spinal Cord

Front 2

Peripheral Nervous System Contains

Back 2

Cranial Nerves
Spinal Nerves

Front 3

Afferent Neurons

Back 3

These are sensory neurons that transmit impulses to the spinal cord and brain from all parts of the body.

Front 4

Efferent Neurons

Back 4

These are motor neurons that transmit impluses away from brain and spinal column to all parts of the body.

Front 5

Schwann Cells

Back 5

These are cells of myelin, that are white and fatty.

Front 6

Nodes of Ranvier

Back 6

These are indentations between adjecent schwanns cells.

Front 7

Glia or Neuro Glia

Back 7

Known as nerve glue, special types of supporting cells.

Front 8

Oligodendrocytes

Back 8

These help hold nerve fibers together, and produce fatty myelin sheaths that evelopes nerve fibers.

Front 9

Synapse

Back 9

These are microscopic spaces that seperate the axon ending of one neuron from the dendrites of another neuron.

Front 10

Neuro Transmitters

Back 10

Chemicals by which neurons communicate

Front 11

Divisions of the Brain

Back 11

Brain stem
Cerebellum
Diencephalon
Cerebrum

Front 12

Brain Stem Contains

Back 12

Medulla Oblongata
Pons
Mid-Brain

Front 13

Medullas oblongata

Back 13

Two-way conduction pathway between the spiinal cord and highter brain centers; cardiac, respiratory, and vasomotor control center.

Front 14

Pons

Back 14

Two-way conduction pathway between areas of the brain and other regions of the body; influeneces respiration

Front 15

Midbrain

Back 15

Two-way conduction pathway; relay for visual and auditory impulses

Front 16

hypothalamus (Diencephalon)

Back 16

Regulation of body temperature, water balance, sleep-cycle control, appetite, and sexual arousal.

Front 17

Thalamus (Deincephalon)

Back 17

Sensory relay station from various body areas to cerebral cortex; emotions and alerting or arousal mechanisms.

Front 18

Cerebellum

Back 18

Muscle coordination; maintenance of equilibrium and posture.

Front 19

Cerebrum

Back 19

Sensory perception, emotions, willed movements, consciousness, and memory

Front 20

Convolusions or Gyri

Back 20

These are ridges and grooves in the outer surface of the cerebrum

Front 21

Corpus Callosum

Back 21

This divides the cerbrum into right and left halves

Front 22

Spinal Cord

Back 22

Seventeen to Eightenn inches long, lies inside the spinal coumn and inside spinal cavity and extends from occipital bone to the bottom of first lumbar vertebrae.

Front 23

Cervical Nerves

Back 23

Twelve

Front 24

Thoracic Nerves

Back 24

Twelve

Front 25

Lumbar Nerves

Sacral Nerves

Back 26

Five

Front 27

Dura Mater

Back 27

This is the tough outer layer that lines the vertebral cannal.

Front 28

Pia Mater

Back 28

This is the inner most membrane covering the spinal cord.

Front 29

Arachnoid Space Mater

Back 29

This is the membrane between the dura and pia mater.

Front 30

Meningitis

Back 30

Infection or inflammation of the meninges.

Front 31

Meninges

Back 31

This is a tough fluid membrane that surrounds the spinal cord and brain.

Front 32

Autonomic Nervous System

Back 32

Consists of motor neurons that conduct impulses from spinal cord or brain stem to cardiac, smooth, or glandular tissue.

Front 33

Functions of Sypathetic Nervous System

Back 33

Dilates, Stops Secretion, Dilates bronchials, Tachycardia, Secretes Addrenaline, Decreases stomach secretions, Decreases motility in intestine, Retains colon contents, and delays emptying of bladder.

Front 34

Functions of Parasypathetic Nervous System

Back 34

Constricts, Secretes Saliva, Constricts bronchials, bradycardia, increases stomach secretions, increases motility in intestine, emptys colon, emptys bladder.

Front 35

Autonomic Neuro Transmitters

Back 35

Theses are the chemical compounds released from the axon terminals of autonomic neurons.

Front 36

Cholinergic Fibers

Back 36

Axons are classified as these.
