chapter 14 Flashcards
initiated by stimulus acting on sensory receptors
sensation
awareness of changes in the internal and external environment
sensation
what responds to stimuli by generating an AP- propagate along sensory nerves to spinal cord and brain
sensory receptors
conscious awareness of those stimuli
perception
determine how to respond
interpretatioin
what results when brain interprets the AP’s in the cerebral cortex
perception
how the brain receives information
senses
2 sets of senses are
general and special
somatic and visceral are in what set of sense
general
receptors from skin, muscles, bones and joints
somatic
internal organ info in thoracic and abdominal cavity
visceral
examples of somatic senses
touch, pressure, proprioception, temperature, and pain
smell taste, vision, hearing, and balance is what type of sense
special sense
does all sensory info detected by sensory receptors result in perception
no
some APs go to the brain area where they are not
perceived
sent to cerbellum=
unconscious level
some variable info is processed unconsciously in medulla (BP) vs taking up all activity is
homeostatic info
cerebral cortex screens info and not perceive many APs=
selective awareness (attention worthy)
awareness of all info at cerebral cortex
inability to function
sensory receptors 3 criteria
- types of stimulus they detect
- location in the body
- receptor structure
