Question 3

Motor Function

Answer 3

Responding to Integrated decisions

Question 4

CNS (CENTRAL NERVOUS SYSTEM)

Answer 4

BRAIN AND SPINE

Question 5

PNS (PERIPHERAL NERVOUS SYSTEM)

Answer 5

ALL OTHER MOVEMENTS

Question 6

KEY FACTORS OF CNS

Answer 6

• CNS consists of brain and Spinal Cord
• Brain acts as a computer for both conscious and unconscious nervous activity
• Spinal cord allows for information to travel from Brain to rest of the body
• The CNS is key in maintaining a relatively stable and constant internal environment through homeostaisis

Question 7

KEY FACTORS OF PNS

Answer 7

• Consists of nerves outside of the CNS
• Divided into Sensory nerves and motor nerves
• Sensory nerves inform the CNS about what is going on within the body.
• Motor nerves of the PNS are divided into

Question 8

Somatic Nervous system

Answer 8

Controls voluntary movements of the skeletal muscles

Question 9

Autonomic Nervous System

Answer 9

Regulates involuntary bodily functions such as HR, digestion and breathing

Question 10

PARTS OF THE BRAIN

Answer 10

Brain stem
cerebellum
cerebrum
Diencephalon

Question 11

Brain stem

Answer 11

connects brain to spinal cord. Nerve messages pass through the brain stem

Question 12

Cerebellum

Answer 12

controls balance and coordination

Question 13

Cerebrum

Answer 13

two hemispheres, left and right and allows for voluntary control of movement

Question 14

Diencephalon

Answer 14

Thalamus (motor control) and Hypothalamus (homeostasis)

Question 15

TYPES OF SENSORY INPUTS

Answer 15

PROPRIOCEPTORS, CHEMORECEPTORS,BARORECEPTORS

Question 16

proprioceptors

Answer 16

specialized cells located in muscles, tendons joints and inner ear

Question 17

Chemoreceptors

Answer 17

Detect chemicals in the mouth (taste) nose (smell) and bodily fluids, They are found in the neck and the aorta

Question 18

Baroreceptors

Answer 18

pressure sensitive nerve cells, they detect high or low pressure, located in aorta and carotid arteries

Question 19

Endocrine system

Answer 19

The Endocrine system partners with the nervous system in regulating the human body and controlling responses of physiological change,

Question 19

Hormones

Answer 19

Hormones are chemical released by glands or tissues to control and regulate activity of other cells around the body

Question 20

Epinephrine and norepinephrine

Answer 20

Released from adrenal medulla
