Chapter 10 Nervous System Anatomy

Front 1

Function of Cerebrum

Back 1

thinking, personality, sensations, movements, memory

Front 2

Function of Thalamus

Back 2

relaystation for sensory impulses; pain

Front 3

Function of the Hypothalamus

Back 3

body temp; sleep; appetite; emotions control of the pituitary gland

Front 4

Function of the Cerebellum

Back 4

coordination of volunatary movements and balance

Front 5

Function of the Pons

Back 5

connection of nerves (to the eyes and face)

Front 6

Function of the Medulla Oblongata

Back 6

nerve fibers cross over, left to right and right to left; contains centers to regulate heart, blood vessels, and respiratory system

Front 7

What does the Central Nervous System (CNS)

Back 7

brain & spinal cord

Front 8

What does the Peripheral Nervous System (PNS)

Back 8

peripheral nerves in the body

Front 9

Two types of Nerve Cells

Back 9

neuron & glia

Front 10

Neuron

Back 10

conducts impulses, parenchymal

Front 11

Glia

Back 11

connects or supports neurons

Front 12

Function of a Neuron

Back 12

to send impulses for body functions

Front 13

Three parts of a Neuron

Back 13

dendrites, cell body & axon

Front 14

Three types of Neurons

Back 14

sensory, efferent neuron & interneuron

Front 15

What covers the Axon

Back 15

myelin sheath

Front 16

Myelin Sheath

Back 16

white-fatty substance which is formed by schwann cells

Front 17

White Matter

Back 17

axons covers w/myelin

Front 18

Three types of Glia

Back 18

astrocyte, microglial & oligodendrocyte

Front 19

Ependymal Cell

Back 19

produces fluid that circulates within brain & around spinal cord

Front 20

Pathway of a Neuron

Back 20

stimulus > dendrite > cell body > axon + neurotransmitter > synapse > dendrite of next neuron

Front 21

Neurotransmitter

Back 21

chemical by which neurons communicate

Front 22

Acetylocholine

Back 22

released in spinal cord & at neuromuscular junctions

Front 23

What does a deficiencey in Dopamine cause?

Back 23

Parkinsons

Front 24

Dura Mater

Back 24

contains channels for blood to enter brain tissue

Front 25

Arachnold Membrane

Back 25

appears like "spider webs"

Front 26

Paimater

Back 26

closest to brain and spinal cord

Front 27

Brain Divisions

Back 27

brainstem, cerebellum [2nd largest area movement & balance], diencephalon

Front 28

Cerebellum Divisions

Back 28

medulla oblongata, pons, mid brain

Front 29

Division of diencepalon

Back 29

Hyopthalmus & Thalamus

Front 30

Gyri

Back 30

ridges of the brain

Front 31

Sulci

Back 31

groves of the brain

Front 32

What does the Frontal Lobe control?

Back 32

thought processes, behavior, personality, emotion

Front 33

What does the Parietal Lobe control?

Back 33

body sensations, visual and spatial perception

Front 34

What does the Occipital Lobe control?

Back 34

vision

Front 35

What does the Temporal Lobe control?

Back 35

hearing, understanding, speech & language

Front 36

Cerebrospinal Fluid

Back 36

found in middle of cerebrum and is continously formed form fluid filtering out of the blood

Front 37

Plexus

Back 37

group of nerves

Front 38

Aplexus

Back 38

a large network of nerves in the peripheral nervous system

Front 39

Sympathetic

Back 39

stimulates the body in times of stress & crisis

Front 40

Parasympathetic

Back 40

controls visceral effectors under normal conditinos
