Concept explainers
To determine:
The olfactory pathway from the time an odor reaches the olfactory epithelium till the nerve impulse reaches the final destination.
Introduction:
The ability of smell is achieved by olfactory organs that are a part of the nasal cavity. The nasal cavity is lined with the olfactory sensory neurons that aids in detecting the fragrance from the airborne particles. As the air enters the nasal cavity, the particles also enter the cavity along with the air. The swirling action of air brings the water and fat soluble odorants in contact with the sensors.

A speech processor selects sounds in the range of human speech, and a transmitter converts these sounds to electrical impulses, which are then sent to the auditory nerve. Which of the following types of hearing loss would not be restored by a cochlear implant? Hearing loss resulting from absence or loss of hair cells in the organ of Corti. Hearing loss resulting from an abnormal auditory nerve. Hearing loss resulting from fracture of the cochlea. Hearing loss resulting from damage to bones of the middle ear.arrow_forward
