This portion of the outer tunic is referred to as the “white of the eye”.
This area is where the retina and the optic nerve join; contains no rods or cones; “blind spot”
This area has the highest concentration of cones; the focal point of light needs to converge here for the sharpest vision.
An inner tunic layer; contains rods & cones. point of light needs to converge here for the sharpest vision.
The vitreous humor
a. damage to the cornea
b. damage to the optic nerve
c. an improper diet
d. a toxic effect of vitamin A
Because of a LACK of vitamin A
This tube connects the middle ear to the throat. Aka-the Eustachian tube.
Improperly blowing your nose could pass an infection to which part of your ear?
The middle ear
Tympanic membrane which part of your ear?
This structure- begins the middle ear; the malleus is attached to; vibrates from sound waves.
Oval window which part of your ear?
The stapes vibrates this membrane attached to the cochlea. Causing waves in the perilymph.
auricle which part of your ear?
The outer fleshy portion of the ear.
malleus which part of your ear?
Auditory ossicle that is attached to the eardrum. Passes the vibration to the incus.
Semicircular canals which part of your ear?
An infection in this structure could cause dizziness.
Put the following in order as light passes through the eye. which part of your ear?
2. aqueous humor
4. vitreous humor
a. middle ear
d. anterior chamber of the eye
When these are distorted (bent) against the tectorial membrane, an action potential is sent to the brain.
cortex of temporal lobe
olfactory bulb- olfactory tract-limbic system-cortex of temporal lobe
c. cordoid coat
d. ciliary bodies
Which part of the brain deciphers taste? the brain:
a. temporal lobe
b. parietal lobe
c. frontal lobe
d. occipital lobe
The malleus moves the incus
The tympanic membrane vibrates
The stapes pushes the oval window
The incus moves the stapes
Sound waves are channeled down the ear canal
1. Sound waves are channeled down the ear canal
2. The tympanic membrane vibrates
3. The malleus moves the incus
4. The incus moves the stapes
5. The stapes pushes the oval window
Which general category of sensory receptors detects variations in temperature?
d. pain receptors
The variations in temperature?otoliths are located in:
a. the middle ear
b. the semi-circular canals
c. the cochlea
d. the saccule in the vestibule
a. endolymph flows over the spiral organ
b. the otoliths bend cilia in response to gravity
c. the tympanic membrane vibrates
d. perilymph bends hair cells
Which of the five senses contains two types of photoreceptors called rods and cones?
Rods function in photoreceptors called rods and cones?
a. color vision
b. dim light vision
c. bright light vision
The sets of color receptors/cones within the retina are sensitive to lights that are
a. red, green, and blue
b. red, blue, and yellow
