Special Senses

Anatomy & Physiology I Lab

QuestionAnswer
What are sensory receptors? Specialized cells that respond to environmental changes (stimuli).
What are general senses? Modified dendritic endings of sensory neurons found throughout the body; monitor most general sensory info.
What are special senses? Vision, hearing, equilibrium, smell, and taste—housed in sense organs.
What do mechanoreceptors detect? Mechanical force such as touch, pressure, vibration, and stretch.
What do thermoreceptors detect? Temperature changes.
What do photoreceptors detect? Light.
What do chemoreceptors detect? Chemicals (taste, smell, internal chemical changes).
What do nociceptors detect? Pain from tissue damage.
What do exteroreceptors detect? Stimuli outside the body (touch, pressure, pain, temp).
What do interoceptors detect? Stimuli inside the body (internal organs, blood vessels).
What do proprioceptors detect? Body position, muscle/tendon stretch, joint movement.
What are nonencapsulated receptors? Free nerve endings with no connective tissue capsule.
What are encapsulated receptors? Nerve endings wrapped in connective tissue.
What percentage of sensory receptors are in the eyes? 70%.
What are the accessory structures of the eye? Eyebrows, eyelids, conjunctiva, lacrimal glands, 6 extrinsic eye muscles.
What are the major structures of the eye? Sclera, cornea, choroid, ciliary body, iris, pupil, lens, retina, aqueous humor, vitreous humor, macula lutea, fovea centralis
What is myopia? Nearsightedness; distant objects focus in front of the retina.
What is hyperopia? Farsightedness; distant objects focus behind the retina.
What is glaucoma? Blocked aqueous humor drainage → increased pressure → damage to retina/optic nerve.
What are cataracts? Clouding of the lens.
What is conjunctivitis? Inflammation of the conjunctiva (pinkeye).
What is astigmatism? Irregular cornea or lens shape causing blurred vision
What stimulates hearing? Fluid movement that activates internal ear mechanoreceptors.
What provides balance? The same fluid movement stimulating mechanoreceptors for head position and movement.
What are the 3 parts of the ear? External ear, middle ear, internal ear.
What structures are in the external ear? Auricle (pinna), external acoustic meatus, ceruminous glands.
What structures are in the middle ear? Tympanic membrane, auditory ossicles, pharyngotympanic tube.
What structures are in the internal ear? Semicircular canals, vestibule (utricle & saccule), cochlea.
What is the bony labyrinth? Channels in the temporal bone filled with perilymph.
What are the 3 regions of the bony labyrinth? Vestibule, semicircular canals, cochlea.
What is the membranous labyrinth? Membranous sacs/ducts inside the bony labyrinth filled with endolymph
What conducts sound vibrations? Perilymph and endolymph.
What is deafness? Any degree of hearing loss.
What is conduction deafness? Blockage prevents sound from reaching internal ear.
What is sensorineural deafness? Damage to neural structures like hair cells or auditory cortex
What is tinnitus? Ringing, buzzing, clicking without sound—often due to nerve degeneration or inflammation.
What is Ménière’s syndrome? Inner ear disorder causing severe vertigo, nausea, and balance problems.
What type of receptors do taste and smell use? Chemoreceptors.
What must chemicals do to be detected by taste and smell receptors? Be dissolved in fluid.
What structures are involved in taste? Tongue, fungiform/vallate/foliate papillae, taste buds, taste pores, gustatory hairs.
What are the 5 basic taste sensations? Sweet, sour, salty, bitter, umami.
What structures are involved in smell? Nose, nasal conchae, olfactory cilia, nasal mucus, olfactory bulbs.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
