General Senses (BIO 181-201) Flashcards
Somatic
pressure, pain, ect.
Visceral
Senses in organs
all over body
not consciously perceived
Special Senses
senses in local areas (specific structures)
taste and smell
(can’t smell with hand, only with nose)
nociceptors
respond to pain
mechanoreceptors
pressure vibration
tactile receptors
a lot of them
rapid or slow adapting
free nerve endings
somatic chemical stimulation pressure temperature changes trauma
root hair plexus
visceral
monitor distortion of hair and movement across body surface
tactile corpuscles
visceral fine touch pressure low frequency vibration eyelids, lips, fingertips, nipples, external genitalia
lamellated corpuscles
deep pressure
visceral
pulsing and high frequency
fast adapting receptors
Ruffini Corpuscles
somatic
pressure and distortion of skin
deep reticular dermis
proprioceptors
- monitor position of joints and muscles
- most structurally and functionally complex general sensory receptors
Golgi Tendon Organs
- somatic
- stimulated by tension
- located at junction between skeletal muscle and its tendon
chemoreceptors
respond only to water soluble and lipid soluble substances
