Front (Question)

Modality

Back (Answer)

Type of stimulus that is detected by a sensory system

Front (Question)

Transduction

Back (Answer)

Process of converting the energy of a stimulus into an electrical signal

Front (Question)

How do sensory receptors send signals they receive

Back (Answer)

They convert the signals associated with sensory stimuli into neural signals-afferent sensory electrical signals that can be transmitted to CNS

Front (Question)

What helps us enhance the detection of sensory stimuli

Back (Answer)

Specialized anatomic structures that house sensory receptors such as eyes

Front (Question)

Optic nerve

Back (Answer)

Part of the CNS, covered with myelin produced by oligodendrocytes. U blind without it

Front (Question)

Ciliary body

Back (Answer)

Adjust the refractive power of the lens

Front (Question)

What do cornea and lens have in common

Back (Answer)

Both transparent

Front (Question)

Cornea responsible for

Back (Answer)

Refraction of light on the air/cornea interface

Front (Question)

Lens function and structure

Back (Answer)

Bringing objects at various distances into focus. Lens is elastic and can change shape to accommodate its refractive power

#10

Front (Question)

Ciliary processes produce

Back (Answer)

Fluid(aqueous humor) to maintain intraocular pressure

#11

Front (Question)

Narrowing the pupil leads to

Back (Answer)

Reduction aberrations and increases the depth of field(distance at which object can be seen clearly)

#12

Front (Question)

Light always focused on

Back (Answer)

Fovea

#13

Front (Question)

Optic disk has no light receptors therefore

Back (Answer)

Doesn’t detect light

#14

Front (Question)

Optic disk definition

Back (Answer)

Area where blood vessels enter the eye and retinal axons leave the eye

#15

Front (Question)

Visual field

Back (Answer)

Part of visual space seen by an eye

#16

Front (Question)

Images of visual fuel project onto the surface of the retina are

Back (Answer)

Inverted

#17

Front (Question)

Visual fields are divided into

Back (Answer)

Quadrants

#18

Front (Question)

Lines that divide visual field into quadrants intersect at fixation point which is

Back (Answer)

The point in visual space that falls on the fovea

#19

Front (Question)

Retina

Back (Answer)

Part of the NS that forms neural portion of the eye. Electrical activity of the retinal photoreceptors is converted into electrical signals that are transmitted to central targets

#20

Front (Question)

Neurons in the retina

Back (Answer)

• photoreceptors • bipolar cells • Horizontal cells • amacrine cells • Ganglion cells

#21

Front (Question)

Closest layer of the retina to the brain

Back (Answer)

Pigment epithelium cells layer

#22

Front (Question)

Weird way retina works

Back (Answer)

Light has to go thru layers of cells to reach photoreceptors

#23

Front (Question)

Blind spot

Back (Answer)

Region where ganglion cells axons come together and leave eye, no photoreceptors in this region

#24

Front (Question)

Horizontal and amacrine cells act like neurons how

Back (Answer)

The can inhibit or excite cells and modulate their interactions
