nervous system

Question 1

nervous system

Answer 1

communicating system for the body receive and processes and responds to stimuli

Question 2

central nervous system

Answer 2

processes and response to information from PNS

Question 3

peripheral nervous

Answer 3

processes and responds to information from CNS

Question 4

brain

Answer 4

master control organ responsible for everything

Question 5

spinal cord

Answer 5

sends sensory information from CNS to PNS
sends motor information from PNS to CNS

Question 6

somatic nervous system

Answer 6

voluntary actions carry messages to and from organs, muscles, glands and skeletal muscles

Question 7

autonomic nervous system

Answer 7

involuntary actions, visceral muscles

Question 8

sympathetic nervous system

Answer 9

regulates normal functioning\homeostasis
responsible for freeze response

Question 10

spinal reflex

Answer 10

involuntary unconscious response controlled by somatic nervous system

Question 11

spinal reflex process

Answer 11

1. receptors detect stimulus
2. information from receptors travel through sensory neurons in afferent direction towards CNS
3. interneurons in spinal cord intercept messages and initiate response
4. motor neurons transmit messages in an efferent direction to skeletal muscles to move
5. messages continues to brain for processing\perception of pain
