Q

what happens during sensory input of the nervous system?

A

electrical impulses sent from the sensory organs to CNS by sensory receptors to monitor stimuli, then sensory receptors convert the stimuli into sensory input received by the CNS

17
Q

what are sensory receptors?

A

nerve endings in the sensory organs

18
Q

what is stimuli?

A

changes in the external or internal (body) environment

19
Q

what happens during integration of the nervous system?

A

CNS processes and interprets the sensory input through the sensory organs

20
Q

what are the parts of the nervous system?

A

brain, spinal cord, nerves

21
Q

what happens during motor output in the nervous system?

A

CNS transmit messages to effectors to generate a response to stimuli, then either voluntary or involuntary movement is outputted

22
Q

what are the effectors of the nervous system?

A

muscles and glands

23
Q

what is voluntary movement?

A

movement made by skeletal muscle
