chapter 11 part 1

functions of the nervous system (4)

maintaining homeostasis, monitoring stimuli, integrating information, transmitting info via AP (shit. stimuli homeostasis information trasmit)

there’s 2 systems responsible for maintaining homeostasis, what is the other

endocrine

2 sections of the nervous system

central - brain and spinal cord

peripheral - sensory neurons and motor neurons

2 sections of the peripheral nervous system and their responsibilities

somatic - voluntary movements

autonomic - involuntary functions

sensory activities involve ________ stimuli and sending ______

detecting, signals to brain

neurons that carry sensory information toward the CNS are called

afferent/sensory neurons

motor activities involve sending signals from _______ to the ________

CNS to the effectors

motor activities are carried out by _______ _______

efferent or motor neurons

these neurons carry out integrative activities by transmitting signals between neurons

interneurons

3 main responsibilities of the central nervous system

receive information from body, process sensory info, and respond to stimuli

2 main reseponsibilities of the peripheral nervous system

detect stimuli and communicate the info to CNS

neurons in the PNS are bundled in structures called

nerves

the autonomic nervous system (ANS) controls

involuntary functions

the sympathetic division controls

fight or flight response

the parasympathetic division controls

the feed and breed (or rest and digest) response

the somatic nervous system is responsible for

voluntary control of skeletal muscles

main part of a neuron is the _____ _______ (soma), which contains the _______

cell body (soma), nucelus with genetic material

dendrites carry signal ________, and axon carries them _______

toward the cell body, away from cell body

site where axon begins

axon hillock

the parasympathetic division controls this response

feed and breed (rest and digest)

bipolar neurons are found in these places (face)

eye and nasal cavities

sensory neurons are this type of structural category of neurons

pseudo-unipolar

multipolar neurons are found in

brain and spinal cord. they need the full thing

anaxonic neurons have no

axon
