Vision, hearing, taste, smell
Tear duct, flows from top outer corner to the hole in the lacrimal bone
membrane on outside of the eye and on the inside of the eyelid
wall of the eye (the whites)
clear front wall of the eye
carries impulses from retina to optic chiasma
colored part of the eye
Hole through iris
fluid between cornea and the lens. it provides support and nutrients to the cornea
behind the iris, held in place by the suspensory ligaments. it focuses light on to the retina
Muscles that pull ligaments that focus the lens
fine threads that hold the lens
gel-like liquid behind the lens
inner lining of the back part of the eyeball where the photoreceptors are found.
Photoreceptors around the edges of the retina. they sense blurry images in black and white
Photoreceptors in the center of the retina. they sense colors and fine detail.
area with the most cones
Area with no rods or cones, where the nerve begins and information is sent.
the bending of light
focusing of the eye
the visual pathway
cornea > aqueous humor> lens> Vitreous humor> photoreceptors on the retina> optic disc> optic nerve> optic chiasm> optic tract> thalamus> occipital lobe
Outer cone shaped structure that gathers sound
External Auditory canal
also know as External accoustic meatus, carries sound waves to the tympanic membrane
glands that produce ear wax or cerumen
eardrum, vibrates when hit by sound waves
3 small bones the malleus incus and the stapes
connect middle ear to the throat
membrane that borders the inner ear and middle ear
shell shaped structure in the inner ear
organ of corti
structure that contains hearing receptors called hair cells
outer ear> tympanic membrane> middle ear (auditory ossicles) > oval window> inner ear (cochlea and organ of corti) > impulse is sent on the vestibulocochlear nerve > thalamus > temporal lobe
sense of balance, static (euilibrium while at rest) and dynamic (equilibrium while in motion)
entryway, area between cochlea and semicircular canals
sense of taste (five basic tastes sweet, sour, bitter, salt, umami)
Sense of smell. sensors are located on the very top of the nasal cavity
