PERIPHERAL NERVOUS SYSTEM

Question 1

PERIPHERAL NERVOUS SYSTEM

Answer 1

• peripheral nervous system sends sensory information from the eyes, ears and other sense organs to the CNS.
• The PNS also carries messages from the brain and spinal cord to the muscles, glands and other parts of the body
• Not protected by bone
• Has two subsystems: somatic and autonomic NS

Question 2

• peripheral nervous system sends sensory information from the eyes, ears and other sense organs to the CNS.
• The PNS also carries messages from the brain and spinal cord to the muscles, glands and other parts of the body
• Not protected by bone
• Has two subsystems: somatic and autonomic NS

Answer 2

PERIPHERAL NERVOUS SYSTEM

Question 3

SOMATIC NERVOUS SYSTEM (SNS)

Answer 3

• the subsystem of the peripheral nervous system that transmits information from the senses to the CNS and carries signals from the CNS to the muscles

Question 4

• the subsystem of the peripheral nervous system that transmits information from the senses to the CNS and carries signals from the CNS to the muscles

Answer 4

SOMATIC NERVOUS SYSTEM (SNS)

Question 5

SENSORY NEURONS

Answer 5

• cells in the nervous system that provide information to the brain about the environment

Question 6

• cells in the nervous system that provide information to the brain about the environment

Answer 6

SENSORY NEURONS

Question 7

MOTOR NEURONS

Answer 7

• cells in the nervous system that the brain uses to influence muscles and other organs to respond to the environment in some way

Question 8

• cells in the nervous system that the brain uses to influence muscles and other organs to respond to the environment in some way

Answer 8

MOTOR NEURONS

Question 9

AUTONOMIC NERVOUS SYSTEM (ANS)

Answer 9

• subsystem of the peripheral nervous system that carries messages between the central nervous system and the heart, lungs and other organs and glands
• These messages increase or decrease the activity of the organs and glands to meet varying demands placed on the body
• Controls activites outside conscious control: perspiration, sweating
• Two branches: sympathetic and parasympathetic

Question 10

• subsystem of the peripheral nervous system that carries messages between the central nervous system and the heart, lungs and other organs and glands
• These messages increase or decrease the activity of the organs and glands to meet varying demands placed on the body
• Controls activites outside conscious control: perspiration, sweating
• Two branches: sympathetic and parasympathetic

Answer 10

AUTONOMIC NERVOUS SYSTEM (ANS)

Question 11

SYMPATHETIC NERVOUS SYSTEM

Answer 11

• the subsystem of the autonomic nervous system that readies the body for vigorous activity
• mobilises the body in the face of stress—fight or flight

Question 12

• the subsystem of the autonomic nervous system that readies the body for vigorous activity
• mobilises the body in the face of stress—fight or flight

Answer 12

SYMPATHETIC NERVOUS SYSTEM

Question 13

PARASYMATHETIC NERVOUS SYSTEM

Answer 13

• the subsystem of the autonomic nervous system that typically influences activity related to the protection, nourishment and growth of the body
• regulates the body’s energy-conserving function

Question 14

• the subsystem of the autonomic nervous system that typically influences activity related to the protection, nourishment and growth of the body
• regulates the body’s energy-conserving function

Answer 14

PARASYMATHETIC NERVOUS SYSTEM
