The hair cell-containing sensory epithelium of the semicircular canals b. Gelatinous structures in the semicircular canals which the hair cell bundles are embedded c. Gelatinous membrane on which the otoconia lie and in which the tips of the hair bundles are embedded d. A line found in both the sacculus and utricle that divides the hair cells into two populations with opposing hair bundle polarities e. Referring to the internal ear; comprises the cochlea, vestibular apparatus, and the bony canals in which these structures are housed f.

Unformatted text preview: and cupulae h. The calcium carbonate crystals that rest on the otolithic membrane overlying the hair cells of the sacculus and utricle i. Inability to fixate visual targets while the head is moving as a result of vestibular damage j. Ganglion containing the bipolar cells that innervate the semicircular canals and otolith organs k. Axon tract that carries excitatory projections form the abducens nucleus to the contra-lateral oculomotor nucleus; important in coordinating conjugate eye movements l. Otolith organs that senses linear accelerations and head tilts in the horizontal plane m. Involuntary movement of the eyes in response to displacement of the head. This reflex allows retinal images to remain stable while the head is moved n. The central region of the retina that contains the fovea (the term derives from the yellowish appearance of this region in opthalmoscopic examination); also, the sensory epithelia of the otolith organs...
