Involves the organ of corti and Cranial Nerves (CN VIII) | Hearing |
Is the Olfactory Sense; uses chemorecptors | Smell |
Uses mechanoreceptors. sensory information transmitted by the vestibular branch of Cranial Nerves (CN VIII) | Balance |
Gustatory Sensation | Taste |
From photoreceptors to the occipital lobe | Sight |
From receptors to auditory cortex | Hearing |
The layer of the eyeball that contains the photoreceptors | Retina |
The colored muscle portion of the eye that determines the size of the pupil | Iris |
The shape of the structure determined by the ciliary muscles; refracts light | Lens |
Layer of the eyeball that provides the blood supply for the retina | Choroid |
Secreted by the ciliary body and drained by the canal of schlemm | Aqueous humor |
Gel-like substance in the posterior cavity; maintains the shape of the eye and helps hold the retina in place | Vitreous humor |
Contains the radial and circular muscels; mydriasis and miosis | Iris |
The window of the eye; avascular structure | Cornea |
Includes the macula lutea | Retina |
Inner lining of the lids "pink eye" | Conjunctiva |
Contains the malleus, incus, and stapes | Middle ear |
Connected to the pharynx by the eustachian tubes | Middle ear |
Home of cerumen | External ear |
Location of the organ of corti and Cranial Nerve (CN VIII) | Inner ear |
Chochlea, semicircular canals, and vestibule | Inner ear |
Endolymph and perilymph; mechanoreceptors | Inner ear |
Separated from the middle ear by the tympanic membrane | External ear |
Separated from the inner ear by the oval window | Middle ear |
Bone conduction deafness | Middle ear |
Nerve conduction deafness | Inner ear |
The retina _________________ | contains rods and cones |
What is the consequence of diminished blood flow to the choroid? | the retina dies |
A drug or effect that is described as mydriatic ______________ | dilates pupil |
Which of the following does not describe the middle ear? | it is the location of the organ corti |
The organ of corti_______________________ | is the receptor for hearing |
Touch, pressure, pain, and temperature are _____________________ | classified as general senses |
Cranial Nerves III, IV, and VI____________________ | innervate the extrinsic eye muscles |
Which of the following is not a sense? | Lacrimation |
Which of the following best describes theses structures: superior oblique, inferior oblique, superior rectus, inferior rectus, medial rectus and lateral rectus? | Extrinsic eye muscles |
Which of the following is least related to the eyelids? | optic nerve |
Light waves pass through the _____, the avascular extension of the sclera. The light goes through the opening in the iris called___and then through a refracting structure called the ________. | cornea, pupil, lens |
In daylight, the light waves focus on the ____the area of most acute vision because of the high numbers of ___, the waves are scattered along the periphery of the retina, stimulating the ___ the photoreceptors for color vision. | fovea centralis (macula lutea), cones |
In dim light,the light waves are scattered along the periphery of the retina, stimulating the _, the photoreceptors for night vision. Action potential(nerve impulses) are formed by the stimulated photorecptors located in the inner layer of the eye, called | rods, retina |
The nerve impulses travel along the _____ nerve to the ______ lobe of the cerebrum. | optic, occipital |
Sound waves travel through the external auditory canal and bump into the ___ causing the "drum" to vibrate. The vibration is transmitted to the three tiny ossicles called ___, ____, and _____. | tympanic membrane, mallus (hammer), incus (anvil), and stapes (stirrups) |
The ___ vibrates against the oval window, causing the fluid within the inner ear to move. The inner ear fluid, called ___, bends the hairlike projections of the receptors, called ___. | cochlear, endolymph, and organ of corti |
When the hairs are bent, action potentials are fired; the nerve impulses travel the ____ branch of the CN VIII to the ____ love of the cerebrum. | cochlear and temporal |
