Pre-lab 5 and Exam 6 - weeks 11 + 12

Question 1

Which eye structure “accommodates” to see near and far objects?

Answer 1

lens

Question 2

one difference between rods and cones

Answer 2

Rods can function in low light whereas cones can only function in bright light.

Question 3

Both the peroneus longus and peroneus brevis muscles originate on what bone?

Answer 3

fibula

Question 4

Receptor cells for which sensation are renewed in approximately 7-10 days?

Answer 4

gustation

Question 5

According to your text, lacrimal glands release tears during emotional responses due to stimulation of which specific division of the nervous system?

Answer 5

parasympathetic

Question 6

Type of receptor for:

cold
pain
vision
gustation
hearing

Answer 6

cold = thermo
pain = nociceptors
vision = photo
gustation = chemo
hearing = mechanical

Question 7

When you have a cold, your ability to taste is diminished in great part because the brain cannot receive information for what other sensation that we use to perceive taste?

Answer 7

olfaction

Question 8

Reflex arcs and the pathway for sensation are similar in some ways. One difference is that in sensation, a nerve impulse needs to be conveyed to the brain, whereas in some reflex arcs the message only needs to reach the (BLANK) before an efferent signal is sent.

Answer 8

spinal cord

Question 9

The photopigment retinal is derived from which vitamin?

Answer 9

Vitamin A

Question 10

the muscle that extends the big toe and dorsiflexes at the ankle.

Answer 10

extensor hallucis longus

Question 11

part of the brain where perception primarily occur for:

olfaction
touch
vision
equilibrium

Answer 11

olfaction - temporal lobe
touch -postcentral gyrus
vision - occipital lobe
equilibrium - parietal lobe

Question 12

what receptor is most likely involved in detecting an insect walking on your skin?

Answer 12

hair root plexi

Question 13

The conversion of a nerve impulse into a sensation, by the brain, is referred to as:

Answer 13

translation

Question 14

The characteristic of sensation described as the phenomenon that even though all sensation occurs in the brain it seems like we “feel” with receptors is called what?

Answer 14

projection

Question 15

Which of the three “auditory ossicles” is located between the other two?

Answer 15

incus

Question 16

Which sensation utilized hair cells within the “Organ of Corti” in the cochlea?

Answer 16

hearing

Question 17

What structure separates the outer ear from the middle ear?

Answer 17

tympanic membrane

Question 18

The characteristic of sensation occurring when a sensation diminishes/disappears while the stimulus persists is known as:

Answer 18

adaptation

Question 19

The specific receptors in muscles that “monitor” muscle length are:

Answer 19

muscle spindles

Question 20

Describe a functional difference between rods and cones (mention both).

Answer 20

rods have low acuity and don’t produce color; cones have high acuity and produce colored vision

Question 21

a prime movement of the fibulas brevis

Answer 21

eversion and plantarflextion

Question 22

a prime movement of the tibias anterior

Answer 22

dorsiflexion and inversion

Question 23

a prime movement of tibialis posterior

Answer 23

inversion and plantarflexion

Question 24

The function of any receptor is to:

Answer 24

transduce - convert stimuli into nerve impulses

Question 25

Which of the following senses relied on receptors found in the “vestibule”?

Answer 25

equilibrium

eustachian tube

Question 27

A receptor may structurally be

Answer 27

free nerve ending
encapsulated dendrite
specialized/separate cell

Question 28

Answer 28

limbic system

Question 29

conveys sensory impulses for smell

Answer 29

olfactory nerve

Question 30

transmits sensory impulses for hearing

Answer 30

Question 31

principle brain area for vision

Answer 31

occipital lobe
