Chapter 10: Senses Flashcards
mechanoreceptor
The sense of hearing can be classified as a
photoreceptor
The sense of sight can be classified as a
proprioceptors
The Golgi tendon receptors can be classified as
pain
The free nerve endings in the skin respond to
the skin
General sense organs can be found in the highest concentration in
sclera
The white part of the eye is called the
The conjunctiva
is a mucous membrane covering part of the eye
The colored part of the eye is called the
iris
The cornea
is the clear part of the sclera in the front of the eye
The pupil
is a hole that lets light into the eye
The choroid layer
prevents the scattering of incoming light rays
The innermost layer of the eye is the
retina
The rods in the eye
are used to see in dim light
The cones in the eye
- are part of the retinal layer
- respond to the colors red, green, and blue
The part of the eye with the highest concentration of cones is the
fovea centralis
The ‘‘blind spot’’ of the eye is also called the
optic disc
The vitreous humor
is found in the posterior chamber
The external ear is called the
- auricle
- pinna
The eardrum is
also called the tympanic membrane
The sequence of the ossicles from the eardrum to the inner ear is
malleus, incus, stapes
In the middle ear, the
stapes rests against the oval window
The structure that separates the middle ear from the inner ear is the
oval window
The inner ear consists of three spaces, which are the
vestibule, semicircular canals, and the cochlea
The perilymph is
inside the bony labyrinth
Endolymph is
- inside the cochlea
- inside the semicircular canals
The sense of balance
is classified as a mechanoreceptor
The sense of balance occurs in the
- semicircular canals
- vestibule
The specific organ of hearing is called the
organ of Corti
The sense of taste is classified as a
chemoreceptor
The cells responsible for the sense of taste are the
gustatory cells
The six primary taste sensations are
sweet, salty, metallic, bitter, sour, umami
The sense of smell is classified as
a chemoreceptor
The olfactory receptors
also assist in the sense of taste
The sense of smell is
- sensitive
- easily adapted
- can respond to chemicals dissolved in water
The sense of smell is able to stimulate vivid memories because the olfactory tract passes
through the
limbic
Which of the following sensations is generated by a general sense organ?
Touch
Which of the following sensations is generated by a special sense?
Taste
Which of the following is not considered one of the layers of the eye?
Iris
Which of the following is not part of the vascular layer of the eye?
Cornea
Which of the following is not true about the senses of taste and smell?
Both respond to six primary stimuli
The vestibular nerve contains a nerve from the
- semicircular canals
- vestibule
Which sensation is not sensed by a general sense organ?
Equilibrium
Which sensation is sensed by a special sense organ?
- Smell
- Equilibrium
- Taste
Which of the following is not true of a general sense organ?
They are grouped in a localized area
This is a functional characteristic of all sense organs
- must be able to detect a stimulus
-must be able to detect a change in the intensity of the stimulus - must be able to change the stimulus into a nerve impulse
A condition where the lens of the eye becomes milky in appearance and loses its transparency
is called
a cataract
An infection of the middle ear is called
otitis media
An increase in pressure inside the eye is called
glaucoma
The ‘‘farsightedness’’ of old age is called
presbyopia
Which of the following is part of the sensory pathway of all sense organs?
- Able to sense or detect a stimulus
- Detection of a stimulus is converted to a nerve impulse
- Signal from nerve impulse is conducted to the brain
- Processing information is the sensation perceived in the brain
Why are the many unique flavors we recognize not just tastes alone but a combination of
sensations based on tastes, odors, touch, temperature, and pain?
All incoming signals are integrated with other sensory signals and even memories
to produce our perceptions.
Cornea
Sometimes called the window of the eye
Iris
Colored part of the eye
Pupil
Hole in the eye that lets light in
Choroid
Layer of the eye that keeps light from scattering in the eye
Cones
Structures in the retina that are able to respond to color
Sclera
White of the eye
Conjunctiva
Mucous membrane covering part of the sclera
Lens
Structure that is changed in shape by ciliary muscles to facilitate focus of light
Retina
Innermost layer of the eye
Rods
Structures in the retina that respond in dim light
Malleus
Ossicle that rests against the eardrum
Pinna
Another term for the external ear
Endolymph
Thicker fluid in the inner ear
Semicircular canal
Structure that gives us our sense of balance
Stapes
Ossicle that rests against the oval window
Tympanic membrane
Another term for the eardrum
Organ of Corti
Specific organ of hearing
Oval window
Separates the middle ear from the inner ear
Perilymph
Thinner fluid in the inner ear
