Neuroscience - Nervous System

Question 1

Answer 1

Fragile, hard to heal, most damage is permanent

Question 2

Central nervous system

Answer 2

Decision making organ

Question 3

Brain

Answer 3

Part of central nervous system. Consciousness/life-sustaining

Question 4

Spinal cord

Answer 4

Part of central nervous system. Reflexes, movement.

Question 5

Peripheral nervous system

Answer 5

Transmits central nervous system decisions to other body parts.

Question 6

Somatic nervous system

Answer 6

Part of peripheral nervous system. Conscious information flowing to/from the central nervous system, voluntary movement.

Question 7

Autonomic nervous system

Answer 7

Part of peripheral nervous system. Automatic actions of internal organs and glands.

Question 8

Sensory (afferent) neurons

Answer 8

Part of peripheral, then somatic system. Carries sensory information to the central nervous system.

Question 9

Motor (efferent) neurons

Answer 9

Part of peripheral, then somatic system. Carries information from the central nervous system to the skeletal muscles for actions.

Question 10

Sympathetic division

Answer 10

Part of the peripheral, then autonomic system. Arousal (adrenaline/instant reaction/”stepping on the gas”)

Question 11

Parasympathetic division

Answer 11

Part of the peripheral, then autonomic system. Calming (cortisol/”stepping on the breaks”/slowing down)

Question 12

Reflex arc

Answer 12

Neural pathway that controls a reflex.
Ex. Figure touches fire, sensation routed to spinal cord through sensory neurons, order sent from spinal cord back through motor neurons, hard jerks away from fire.
