Question 8

receptors detech changes in light

Answer 8

photoreceptors

Question 9

detects chemicals in solution

Answer 9

chemoreceptors

Question 10

respond to harmful stimuli

Answer 10

nocireceptors

Question 11

response to stimuli that is rapid and predictable

Answer 11

reflex arc

Question 12

3 components of reflex arc

Answer 12

receptor
integration center
effector organ

Question 13

require no experience/learning to be carried out by the body

Answer 13

intrinsic reflex

Question 14

very rapid movemnet of skeltal muscle tissue (integration center is spinal cord)

Answer 14

spinal reflex arc

Question 15

open space at center of iris : allows light to enter and strike the retina

Answer 15

pupil

Question 16

pupil becomes wider

Answer 16

dilator pupille muscle

Question 17

pupil becomes narrower

Answer 17

sphincter pupillae muscle

Question 18

stimulus applied to 1 side of the body but output is seen on both sides

Answer 18

consensual reflex

Question 19

allows eye to focus on objects at diff distances

Answer 19

accommodation reflex

Question 20

structure in eye that helps focus light directly on the retina by bending light as it enters the eye

Answer 20

lens

Question 21

size of pupil changes according to the distance of object

Answer 21

pupil accommodation

Question 22

lens changes shape to change the ability to refract light to focus it on the retina

Answer 22

lens accommodation

Question 23

lens is more round

Answer 23

stronger refractory power
object is close

Question 24

lens is flatter

Answer 24

weaker refractory power
object is far

Question 25

when an object is close

Answer 25

light is highly scattered as it enters the eye higher refractory power to bend light

Question 26

when an object is far

Answer 26

light is less scattered as it enters the eye weaker refractory power since light doesnt need to bent as much

Question 33

same response as plantar but for children

Answer 33

babinski

ability to maintain the body position and posture in relation to out surroundings

Answer 43

spatial orientation

Question 44

the smaller the receptive area

Answer 44

the more sensitive skin is to touch

Question 45

smallest distance at which two points of contact can be felt

Answer 45

two point threshold

Question 46

stimulus is applied for a prolonged period of time we lose conscious awareness of stimulus

Answer 46

sensory adaptation

Question 47

damage to structure from the tympanic mem to the auditory ossicles prevents transmission of sound to the inner ear

Answer 47

conduction deafness

Question 48

auditory nerve or brain is damaged APs relating to sound are not produced by auditory nerve or cannot be interpreted by the brain
