Correct Answers
1. Describe how the somatic senses differ from the special senses in terms of
their sensory organs.
Somatic senses are only found in the head region, while special senses
are found throughout the body.
Somatic senses, such as touch, do not rely on specialized organs like
the eyes or ears, but instead use receptors distributed throughout
the body.
Somatic senses require complex pathways in the brain similar to
special senses.
Somatic senses are primarily responsible for processing visual
information.
2. What type of receptors are gustatory cells classified as?
Chemoreceptors
Thermoreceptors
Mechanoreceptors
Photoreceptors
3. The outer layer of the eye wall consists of:
Choroid, ciliary body, iris
Conjunctiva, sclera
Cornea, sclera
Conjunctiva, cornea
,4. What is the primary sense organ responsible for hearing?
Eye
Ear
Nose
Tongue
5. Describe how the choroid contributes to the overall function of the eye.
The choroid detects light and sends signals to the brain.
The choroid supplies blood to the retina, which is essential for its
health and function.
The choroid protects the eye from external damage.
The choroid focuses light onto the retina to create clear images.
6. What is olfaction?
The ability to listen
What we would commonly call smell is the detection of chemicals in
the air called odorants by olfactory receptor proteins in the
olfactory organs.
Deep areolar C.T. layer connecting the olfactory epithelium to the
inferior surface of the cribriform plate.
7. Describe the role of fungiform papillae in the sense of taste.
Fungiform papillae contain taste buds that are responsible for
detecting taste stimuli.
Fungiform papillae are primarily involved in the mechanical
processing of food.
, Fungiform papillae are responsible for the perception of smell.
Fungiform papillae are involved in the sensation of touch.
8. The correct order of connections along the olfactory pathway is:
olfactory receptor cells, glomeruli, mitral cells, amygdala and
pyriform cortex.
olfactory receptor cells, mitral cells, glomeruli, amygdala and pyriform
cortex.
amygdala and pyriform cortex, mitral cells, olfactory receptor cells,
glomeruli.
glomeruli, olfactory receptor cells, mitral cells, amygdala and pyriform
cortex.
9. Anosmia can be categorized as:
Acquired
Congenital
Trauma-induced
Degenerative
All of the above
10. Describe how the semicircular canals contribute to the sense of balance.
The semicircular canals transmit visual signals to the brain.
The semicircular canals detect rotational movements of the head,
helping to maintain balance.
The semicircular canals are involved in the perception of smell.
The semicircular canals amplify sound waves for hearing.
, 11. The term diplopia means:
eye strain
blind spot
sensitivity to light
double vision
12. The apex of the tongue is located at the:
body of the tongue
tip of the tongue
base of the tongue
dorsal side of the tongue
13. Which cranial nerve is responsible for innervating the medial rectus muscle?
Optic nerve
Trochlear nerve
Abducens nerve
Oculomotor nerve
14. Describe the significance of the optic chiasm in the context of visual
processing.
The optic chiasm is significant because it enables the crossing of
visual information from the medial fibers, allowing for binocular
vision and depth perception.
The optic chiasm regulates taste sensations.
The optic chiasm is responsible for the sense of smell.
