Document Summary

Superior: describes the vertical position of a structure, a superior structure is above something else. Inferior: describes the vertical position of a structure, an inferior structure is below something else. Anterior: describes the position of a structure front-to-back, an anterior structure is toward the front. Posterior: describes the position of a structure front-to-back, a posterior structure is toward the back. Medial: refers to the position of a structure relative to the midline of the body, a medial structure is toward the midline. The belly button is medial to the hips. Lateral: refers to the position of a structure relative to the midline of the body, a lateral structure is away from the midline. The nostrils are lateral to the tip of the nose. Proximal: refers to the position of a structure relative to where something attaches to the body, a proximal structure is closer to the attachment point.

3. The peripheral receptors of the vestibular system lie in five separate organs for each inner ear, including three semicircular canals and two otolith organs. The three semicircular canals are responsible for the transduction of what?

a. Linear accelerations of the head in the horizontal plane

b. Rotational head motion

c. Tilts of the head relative to gravity

d. Static head position

e. Up-down head motion aligned with gravity

4. The receptor cells of the vestibular system are termed hair cells. Signal transduction in the hair cell results from a cascade of several events. Initially, when movement occurs, stereocilia are deflected. For excitatory signal transduction in hair cells, which of the following series of events is correct?

a. The stereocilia are compressed toward the cell surface by acceleration forces, K+ channels in the stereocilia close, Ca2+ channels in the basolateral cell membrane close, and excitatory neurotransmitter is released

. b. The stereocilia are bent away from the kinocilium, K+ channels in the stereocilia close, Ca2+ channels in the basolateral cell membrane close, and excitatory neurotransmitter is released.

c. The stereocilia are rigid and do not move, endolymph motion forces the K+ channels in the stereocilia open, Ca2+ channels in the basolateral cell membrane close, and excitatory neurotransmitter is released.

d. The stereocilia are bent toward the kinocilium, K+ channels in the stereocilia open, Ca2+ channels in the basolateral cell membrane open, and excitatory neurotransmitter is released.

e. The stereocilia are bent perpendicular to the kinocilium, K+ channels in the stereocilia close, Ca2+ channels in the basolateral membrane open, and excitatory neurotransmitter is released.
