Senses

Front 1

sensory receptors

Back 1

detect environmental changes and trigger nerve impulses for interpretation

Front 2

two major categories of sensory receptors

Back 2

somatic
sepecial

Front 3

somatic

Back 3

Touch, pressure, temperature, and pain

Front 4

sepecial

Back 4

Smell, taste, hearing, equilibrium, and vision

Front 5

chemoreceptors

Back 5

Stimulated by changes in chemical concentration

Front 6

Pain receptors

Back 6

stimulated by tissue damage

Front 7

Thermoreceptors

Back 7

Stimulated by change in temperature

Front 8

Mechanoreceptors

Back 8

Stimulated by change in pressure and movement

Front 9

Photoreceptors

Back 9

Stimulated by light energy

Front 10

Sense of touch

Back 10

3 receptors

Front 11

Sensory nerve fibers

Back 11

Associated with sensations of touch and pressure common in epithelial tissue

Front 12

Meissners corpuscles

Back 12

These are associated with light touch and are especially numerous and hair like portions when your skin

Front 13

Pacinian corpuscles

Back 13

Stimulated by heavy and are associated with those areas located in the subcutaneous tissues tendons and joints

Front 14

referred pain

Back 14

When you feel pain elsewhere because the nerves associated with being are located near or around the particular organ

Front 15

sense of smell

Back 15

olfactory sense

Front 16

olfactory organs

Back 16

yellowish brown masses that cover the upper parts of your nasal cavity, covered in cilia

Front 17

olfactory receptors

Back 17

Once olfactory receptors are stimulated, it travels along the olfactory nerves, to the olfactory brain structure where impulses are analyzed, to the olfactory track.

Front 18

interpreting centers

Back 18

temperal and frontal lobes of the cerebrum

Front 19

taste buds

Back 19

special organs of taste

Front 20

papillae

Back 20

tiny elevations on the surface of the tongue

Front 21

taste cells

Back 21

• group of modified epithelial cells
• function as the receptors for the sense of taste

Front 22

taste pore

Back 22

the entire structure is spherical with an opening called

Front 23

hair

Back 23

protrude from a taste cell

Front 24

the four taste sensations

Back 24

sweet
sour
salty
bitter
some recognize :
metallic, alkaline, umani

Front 25

ear

Back 25

organ of hearing
has external, middle, and internal parts.
important role in sense of balance

Front 26

auricle

Back 26

(piena)
Outer funnel like structure

Front 27

External auditory meatus

Back 27

S shaped, tube leads into temporal bone

Front 28

2 parts of external ear

Back 28

auricle
external auditory meatus

Front 29

tympanic membrane

Back 29

eardrum

Front 30

3 bones of the middle ear

Back 30

malleus (hammer)
incus (anvil)
scapes (stirrup)

Front 31

auditory tube

Back 31

eustachian tube
•connects the middle ear to the throat
•allows air to pass between tympanic cavity and mouth

Front 32

eustachian tube

Back 32

Helps maintain official air pressure on both sides of eardrum necessary for hearing

Front 33

inner ear

Back 33

Sounds like a painter communicating chambers and tubes called a labyrinth

Front 34

Semicircular canals

Back 34

function and providing a sense of balance

Front 35

Cochlea

Back 35

Aids hearing

Front 36

Organ of Corti

Back 36

Contains the hearing receptors arranged in rows with hair like structures

Front 37

Equilibrium

Back 37

Controlled by the inner ear

Front 38

2 senses of equilibrium

Back 38

Static and dynamic

Front 39

Static equilibrium

Back 39

Senses the position of the head and helps maintain the stability and posture of the head when you are essentially motionless

Front 40

Dynamic equilibrium

Back 40

The three semicircular canals function to detect motion of the head, and they aid in balancing the head and body during sudden movement

Front 41

vestibule

Back 41

boney chamber between semicircular canals and cochlea

Front 42

presbycusis

Back 42

hearing loss due to age
