What 3 parts of the brain control the ANS?

Back 6

Medulla oblangata, hypothalamus, and the limbic system

Front 7

This type of receptor respond to changes in the concentration of chemical substances (sense of smell & taste, detection of blood concentration changes, etc.)

Back 7

Chemoreceptors

Front 8

These receptors are found only in the eyes and respond to light energy

Back 8

Photoreceptors

Front 9

These receptors are sensitive to changes in temperature

Back 9

Thermoreceptors

Front 10

Name the 3 types of mechanoreceptors

Back 10

Baroreceptors, proprioceptors, and stretch

Front 11

This type of mechanoreceptor sense changes in muscle tension (give person sense of body position)

Back 11

Proprioceptor

Front 12

This type of mechanoreceptor are found in blood vessels and detect change in blood pressure

Back 12

Baroreceptor

Front 13

This type of mechanoreceptor detects degree of inflation in lungs and fullness in stomach

Back 13

Stretch receptor

Front 14

What are pain receptors called?

Back 14

Nocireceptors

Front 15

____ ____ are free nerve endings that are stimulated by tissue damage and respond to various stimuli – excess mechanical, electrical, thermal or chemical change.

Back 15

Pain receptors(nocireceptors)

Front 16

When sensory receptors are continuously stimulated, they may undergo ____ ____ in which the amount of stimuli required for the receptor to respond is increased.
for example a smell becoming less and less noticeable even though the source is still present or becoming accustomed to hot or cold water

Back 16

Sensory adaptation

Front 17

What is the sense of taste called?

Back 17

Gustation

Front 18

In gustation the receptors are the what?

Back 18

Taste buds

Front 19

What is the sense of smell called

Back 19

olfaction

Front 20

In olfaction what are the receptors

Back 20

olfactory receptors

Front 21

______ stimulate by dissolved chemicals in solution
These receptors function with taste receptors (this is why food seems to lose its taste when you have a cold)

Back 21

Chemoreceptors

Front 22

The sharpness of image is called

Back 22

Visual acuity

Front 23

Having normal vision is called

Back 23

emmetropia

Front 24

Nearsightedness is called what?

Back 24

myopia

Front 25

Farsightedness is called what?

Back 25

hyperopia

Front 26

In this condition, an elongated eye results in rays of light focusing in front of retina

Back 26

myopia(nearsightedness)

Front 27

Nearsightedness(myopia) is corrected with ____ lenses, which causes increased divergence of rays

Back 27

concave

Front 28

In this condition, the eyeball is too short, which would result in the focus occurring behind the retina

Back 28

Hyperopia(farsightedness)

Front 29

Hyperopia (farsightedness) is corrected with ____ lens, which increases convergence of light ray

Back 29

Convex

Front 30

In this condition, there is significant asymmetry of the cornea and/or lens and is corrected with uneven lens that is customized to the asymmetry of the cornea or lens

Back 30

Astigmistism

Front 31

In this type of hearing condition, there is impairment of the transmission of sound waves through middle ear

Back 31

Conduction deafness

Front 32

In this type of hearing condition, there is impairment of anywhere from cochlea to the auditory cortex

Back 32

Sensorineural

Front 33

This is composed of two parts and is located within the membranous labyrinth

Back 33

Vestibular apparatus

Front 34

The vestibular apparatus is located within the ____ labryinth which itself is located within the ___ labryinth

Back 34

membranous, bony

Front 35

The membranous labryinth is filled with what fluid?

Back 35

endolymph

Front 36

The bony labryinth is filled with what fluid?

Back 36

perilymph

Front 37

The otolith organs contains the ___ and ___

Back 37

Utricle and saccule

Front 38

The vestibular apparatus is composed of what 2 parts?

Back 38

otolith organs and the semicircular canals

Front 39

This is evoked by structures of the inner ear known as the vestibular apparatus

Back 39

Sense of equilibrium

Front 40

This type of acceleration is detects movement of a car(going slow or fast)

Back 40

Linear acceleration

Front 41

This type of acceleration consists of maintaining one’s balance when turning head, spinning, or tumbling

Back 41

rotational

Front 42

Name the pathway of light

Back 42

cornea  anterior chamber  pupil  lens  posterior chamber  retina

Front 43

This condition is rhythmic shaking or wobbling of the eyes

Back 43

nystagmus

Front 44

This part of the retina contain the light sensitive pigment rhodopsin are highly sensitive to light, therefore providing colorless vision in dim light

Back 44

rods

Front 45

This part of the retina are much less sensitive to light but provide color vision & greater visual acuity the more light, the more these function

Back 45

cones

Front 46

Name the NEURAL pathway of light into the eye

Back 46

retina  optic nerve  optic chiasm (cross-over of axons)  visual cortex of the occipital lobe

Front 47

These are ductless glands that release hormones into blood circulation for transport to target cells
