integumentary, hearing, sight Flashcards
integumentary system
hair, skin, nails, oil glands
skin layers
- epidermis
- dermis
- hyperdermis
langerhans cells
immune cells in epidermis
merkal cells
sensory cells in epidermis
epidermal layers
“come, lets get sunburned”
- stratum corneum
- stratum luciderm (thick skin)
- stratum granulosum
- stratum spinosum
- strutum basale
dermis layers
- papilary layer (fingerprints)
- reticular layer
- subcutis/ hyperdermis (fat)
corpuscles
tactile-touch
lamellar- pressure
presperation types
- insensible- maintain body temp
2. sensible- heat
sweat gland types
- eccrine- palms, feet, forehead
2. apocrine- arm pits and groin
mechanoreceptors
detect sound waves and pressure on the skin and in the inner ear
chemoreceptors
detect the molecules in our food and air
glomerulus
interprets smells
mitral cell
neuron that connects to glomerulus
sound frequency
the number of waves that pass a certain pointin a given time frame- high is short waves
sound amplitude
the difference between the high and low pressures created in the air by the soundwave
external and middle ear
hearing only
inner ear
key to both hearing and equillibrium
pinna or auricle
outer ear
external acustic meatus
auditory canal
tympanic membrane
eardrum
ossicles
malleus-hammer
incus-anvil
stapes-stirrup
organ of corti
interprets sound to the brain
vestibular apparatus
equillibrium
light frequency
determines hue- short blue, long red
light amplitude
determines brightness
cones
fine detail and color
rods
periphereal vision, black and white
