Q

Pacinian corpuscles

A

deepest touch receptors of the tendons and joints also vibrations and body possition

17
Q

Righting relfex

A

keeps our body upright

18
Q

Superficial pain

A

receptors are localized

19
Q

Deep pain

A

not localized receptors

20
Q

Referred pain

A

pain that is felt in a different part of the body then where it is actually coming from

21
Q

Olfactory anatomy

A

Olfactory neuron dendrites have cilia that odorants can attach to. A signal is sent from the neuron to the olfactory bulb then to the brain

22
Q

Neural pathway for olfaction

A

Olfactory axons > olfactory bulb > interneurons > olfactory tracts > olfactory cortex in temporal and frontal lobes

23
Q

Prolonged odorant exposure effects

A

Feedback loop stops sending signal

24
Q

Taste buds

A

structures on the tongue’s papillae, pharynx, palate, and epiglottis that contain sensory receptors for tastes

25
Q

Types of taste

A

sour, salty, bitter, sweet and umami

26
Q

Taste bud anatomy

A

Taste pairs extend from the taste pore and connect to a taste cell. When activated the taste cell sends a signal down a nerve to the thalamus then the temporal lobe

27
Q

Accessory Structures of the eye purpose

A

lubricate, protect and move eye

28
Q

Eye accessory structures

A

eyebrows, eyelids, conjunctiva, lacrimal apparatus, and extrinsic eye muscles

29
Q

Conjunctiva

A

mucous membrane covering the inner eyelids and the surface of the eye

30
Q

Lacrimal apparatus

A

a gland in the the corner of the eye that produces tears

31
Q

nasolacrimal duct

A

duct that leads from the lacrimal sac to the nasal cavity

32
Q

Fibrous tunic

A

the outer layer of the eye made of sclera that attaches the eye to the muscles and the cornea that allows light in.
