Module 5 Strokes

Question 1

Central Nervous System (CNS) consist of:

Answer 1

Brain and Spinal Cord

Question 2

Brain and Spinal cord is protected by:

Answer 2

The Cranium and Spinal Column(Vertebral column)

Question 3

Interneurons

Answer 3

Nerve cells remain inside the brain

Question 4

Afferent Neurons (sensory neurons)

Answer 4

Send signals from Peripheral system to central system

Question 5

Efferent Neurons (motor neurons)

Answer 5

Carry signal from brain to the peripheral system.

Question 6

Brain divide into three parts:

Answer 6

Forebrain
Hind brain
Brain stem

Question 7

Forebrain

Answer 7

Thalamus, Hypothalamus, cerebrum w/ cerebral cortex, parietal lobe, temporal lobe, frontal lobe, and occipital lobe

Question 8

Hind brain

Answer 8

Cerebellum

Question 9

Brain Stem

Answer 9

Connect brain to spinal cord

Question 10

3 Layer Meninges

Answer 10

Dura matter, Arachnoid matter, and Pia matter

Question 11

Dura Matter

Answer 11

Outermost thick layer (inner surface of skull, tip of the spinal cord(filum terminale))

Question 12

Arachnoid Matter

Answer 12

Middle Layer

Question 13

Pia Matter

Answer 13

Innermost Layer (closest to brain, contact with neural tissues of the CNS)

Question 14

Cerebrospinal Fluid

Answer 14

Space between Arachnoid and Pia matter (protection, nutrients, removal of waste products)

Question 15

Peripheral Nervous System(PNS)

Answer 15

Nerves and ganglions that are outside the brain and the spinal cord
(PNS (connects) CNS to peripheral structures)

Question 16

Unlike CNS, PNS

Answer 16

Susceptible to infections and mechanical injuries

Question 17

PNS’s 2 Subsystems:

Answer 17

Somatic Nervous System

Automatic Nervous System

Question 18

Somatic nervous system

Answer 18

Helps body adjust to the external environment through the voluntary movement of Skeletal System
(Blinking Reflex, Knee Jerk Reflex, Gag Reflex, Startle Reflex, Rooting Reflex)

Question 19

Automatic Nervous System

Answer 19

Acts as a control system, functioning largely below the level of consciousness and controlling visceral functions.
(HR, RR, Digestion, Salivation, Perspiration, Pupillary dilation, micturition, sexual arousal)

Question 20

Autonomic Nervous System, 2 main divisions:

Answer 20

Sympathetic: flight or fight
Parasympathetic: Rest and Digestion

Question 21

Cranial Nerves

Answer 21

Carry information into and out of the brain stem.

smell, vision, eye muscles, mouth, taste, ears, neck, shoulders, and trunk

Question 22

Spinal Nerves

Answer 22

Carry motor commands and sensory information into the spinal cord.

Question 23

Myelination

Answer 23

Protects the axon vis insulation, and increase the speed of electrical impulse as it travels along nerve fibers.

Damage: Functional insufficiency

Question 24

Motor Control

Answer 24

Ability to regulate or direct movement
