Document Summary

Deep: superficial, toward the surface of body, deep. Sagittal: vertical plane that divides the body into right and left. Forward/backward movements: movement always parallel to median line, frontal, vertical plane that divides the body into anterior and posterior. Lateral (side-to-side) movements: movement always perpendicular to median line, transverse, horizontal plane that divides the body into cranial and caudal parts, rotational movements, cardinal plane, all 3 perpendicular planes, these planes intersect at the center of gravity. Reference axes: mediolateral, rotations in the sagittal plane occur, anteroposterior, rotations in the frontal plane occur, longitudinal, rotational movements occur transverse actions occur. Types of movement: flexion vs. extension, flexion, decrease angle between 2 segments, extension. Increase angle between 2 segments: dorsi vs. plantar flexion, dorsiflexion, point toes up (toward shin, plantar flexion, point toes down (away from shin, ab. vs. Ad duction: abduction, move away form the midline, adduction, move towards the midline, horizontal abduction/adduction, transverse abduction/adduction.

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

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.
