Pre-lab 5 and Exam 6 - weeks 11 + 12 Flashcards
Which eye structure “accommodates” to see near and far objects?
lens
one difference between rods and cones
Rods can function in low light whereas cones can only function in bright light.
Both the peroneus longus and peroneus brevis muscles originate on what bone?
fibula
Receptor cells for which sensation are renewed in approximately 7-10 days?
gustation
According to your text, lacrimal glands release tears during emotional responses due to stimulation of which specific division of the nervous system?
parasympathetic
Type of receptor for:
cold
pain
vision
gustation
hearing
cold = thermo
pain = nociceptors
vision = photo
gustation = chemo
hearing = mechanical
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?
olfaction
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.
spinal cord
The photopigment retinal is derived from which vitamin?
Vitamin A
the muscle that extends the big toe and dorsiflexes at the ankle.
extensor hallucis longus
part of the brain where perception primarily occur for:
olfaction
touch
vision
equilibrium
olfaction - temporal lobe
touch -postcentral gyrus
vision - occipital lobe
equilibrium - parietal lobe
what receptor is most likely involved in detecting an insect walking on your skin?
hair root plexi
The conversion of a nerve impulse into a sensation, by the brain, is referred to as:
translation
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?
projection
Which of the three “auditory ossicles” is located between the other two?
incus
Which sensation utilized hair cells within the “Organ of Corti” in the cochlea?
hearing
What structure separates the outer ear from the middle ear?
tympanic membrane
The characteristic of sensation occurring when a sensation diminishes/disappears while the stimulus persists is known as:
adaptation
The specific receptors in muscles that “monitor” muscle length are:
muscle spindles
Describe a functional difference between rods and cones (mention both).
rods have low acuity and don’t produce color; cones have high acuity and produce colored vision
a prime movement of the fibulas brevis
eversion and plantarflextion
a prime movement of the tibias anterior
dorsiflexion and inversion
a prime movement of tibialis posterior
inversion and plantarflexion
The function of any receptor is to:
transduce - convert stimuli into nerve impulses
Which of the following senses relied on receptors found in the “vestibule”?
equilibrium
By way of what specific structure(s) might an infection in the throat lead to an ear infection?
eustachian tube
A receptor may structurally be
free nerve ending
encapsulated dendrite
specialized/separate cell
brain area where smell triggers emotions
limbic system
conveys sensory impulses for smell
olfactory nerve
transmits sensory impulses for hearing
vestibulochochlear nerve
principle brain area for vision
occipital lobe
Some receptors in the skin are wrapped around hair follicles, and are related to
fine touch
Which term was used for the sensation of taste?
gustation
