Answer 5

nociceptor

Question 6

receptor for position and movement

Answer 6

proprioceptors

Question 7

two pathways for transmission of sensory signals

Answer 7

anterolateral, dorsal

Question 8

pain and crude touch sensory pathway

Answer 8

anterolateral

Question 9

touch and pressure sensory pathway

Answer 9

dorsal

Question 10

dorsal pathway runs up blank lateral then crosses over in blank

Answer 10

dorsal, medulla

Question 11

sensory cortex that has discrete areas that receive somatic, visual, auditory, and gustatory sensations

Answer 11

neocortex

Question 12

neocortex also has areas for control of blank

Answer 12

movement

Question 13

neocortex receptors are not blank

Answer 13

evenly distributed

Question 14

two types of special senses

Answer 14

photoreceptors, auditory receptors

Question 15

in the eye, light waves change blank via blank

Answer 15

membrane potential, photoreceptors

Question 16

photoreceptor at night and low in detail

Answer 16

rods

Question 17

photoreceptor during day and high in detail and color

Answer 17

cones

Question 18

area of best vision

Answer 18

fovea

Question 19

distant objects… the lens ciliary muscles blank, lense becomes blank, and suspensor ligament gets blank

Answer 19

relax, thinner, tight

Question 20

close objects… the lens ciliary muscles blank, lens becomes blank, and suspensor ligament gets blank

Answer 20

contract, fatter, loose

Question 21

adjustment of focus to compensate for distance

Answer 21

accomodation

Question 22

minimum distance you can focus and gets greater with age

Answer 22

near point discrimination

Question 23

lens becomes less elastic and difficult to focus near images

Answer 23

presbyopia

Question 24

near sightedness

Answer 24

myopia

Question 25

far sightedness

Answer 25

hyperopia

Question 26

eyeball is too blank in near sightedness… blank lenses fix this, and image is focus in blank of fovea

Answer 26

long, concave, front

Question 27

eyeball is too blank in far sightedness… blank lenses fix this, and image is focus in blank of fovea

Answer 27

short, convex, back

Question 28

ear transduces sound waves to blank

Answer 28

mechanical

Question 29

blank cells in ear respond to mechanical waves

Answer 29

hair

Question 30

sound wave of one frequency

Answer 30

tone

Question 31

how we measure sound intensity

Answer 31

decibel
