Smaller Systems of the Peripheral Nervous System

A
  1. Somatic Nervous System
  2. Autonomic Nervous System
37
Q

is responsible for carrying motor and sensory information

A

Somatic Nervous System

38
Q

it is made up of nerves that connect to skin, sensory organs, and skeletal muscles

A

Somatic Nervous System

39
Q

is responsible for nearly all voluntary muscle movements

A

Somatic Nervous System

40
Q

processes sensory information from external stimuli. (Hearing, Touch, and Sight)

A

Somatic Nervous System

41
Q

allow communication to happen between the nerves throughout the body in the Central Nervous System

A

Afferent Sensory Neurons and Efferent Motor Neurons

42
Q

conducting inward

A

Afferent Sensory Neurons

43
Q

take information from the nerves to the Central Nervous System

A

Afferent Neurons

44
Q

conducting outward

A

Efferent Motor Neurons

45
Q

take information from the Central Nervous System to the muscle fibers throughout the body

A

Efferent Neurons

46
Q

2 Parts of Autonomic

A
  • Sympathetic Nervous System
  • Parasympathetic Nervous System
47
Q

vital to our survival

A

Sympathetic Nervous System

48
Q

“Fight or Flight” revs up the body to either defend yourself or escape the threat

A

Sympathetic Nervous System

49
Q

is the counterbalance to the sympathetic response to danger whether real or imagined

A

Parasympathetic Nervous System

50
Q

once the threat is gone, it brings all systems of the body back to normal

A

Parasympathetic Nervous System
