Sensory Organ and System
Type of Sensory Receptor
Location on body
Interoceptors (stimuli inside body)
proprioceptors (stimuli in skeletal muscle and connective tissue)
Extroceptors (stimuli outside body)
Structure
Encapsulated nerve ending
Lamellar corpuscles
Nonencapsulated nerve ending
Bulbous corpuscles
Muscle spindles
Tendon organs
Joint kinestheticreceptors
Type of stimulus
Photoreceptor (light)
Chemoreceptor (specific chemicals)
Thermoreceptor (temperature changes)
Mechanoreceptor (touch/pressure)
Nociceptors (damaging stimuli)
The Sense
tongue - tasting
allow for perception of taste
10000 taste bud on papillae
gustatory epithelial cells
act as chemoreceptors
basal epithelial cells
act as stem cells
ear - hearing
middle ear
tympanic cavity
auditory osccicles
incus
malleus
stapes
inner ear (labyrinth)
bony
vestibule
semicircular ducts
cochlea
scala media (cochlear duct)
scala tympani
scala vestibuli
membranous
external ear
auricle
helix
lobule
nose - smell
Chemoreceptor - volatile substance will interact
Structure of nose
olfactory epithelium
contains million of sensory neuron
palm - touch
eye - vision
Eyebrow - prevent sweat from tricking eye
Eyelid - cover and protect eye
Eyelashes - trigger reflex blinking
