After spinning in an office chair and then standing up quickly, you notice that the room is still spinning even though your head rotation has ceased. Which option best explains this phenomenon? Hair cells release a small amount of neurotransmitter at rest. The continued depolarization of hair cells within the utricle and saccule. Fluid continues to circulate through the semicircular canals. Two of the above.
Which of the following statements is NOT true about the sensory systems? Chemoreceptors are responsible for our senses of taste and smell Mechanoreceptors respond to physical motion and changes in shape A constant sensory stimulus may eventually lead to a decreased response thanks to sensory adaptation All of our senses except for sight travel through the thalamus where they eventually go on to the primary sensory area of the cerebrum Our sensory systems respond to external stimuli like sight and sound, but also internal stimuli like blood sugar levels or muscle contractions

The fluid in your cochlea was in constant motion The amplitude of the sound waves was small Your tectorial membrane was stationary Your stapes was standing still

95 A 53-year-old woman is brought to the physician by her husband who is concerned about her 1-year history of progressive numbness of the hands. He says that 2 days ago she unknowingly burned her left hand because she had no pain. Ophthalmologic examination shows a smaller pupil on the left than on the right and left plosis. Sensation to pinprick and temperature is absent bilaterally over the upper thorax and upper extremities. Sensation to vibration and joint position is intact. There is weakness and atrophy of the intrinsic hand muscles bilaterally. Which of the following is the most likely initial location of the lesion in this patient? A) Anterior white commissure of the spinal cord B) Dorsal root ganglia C) Large myelinated nerves D) Midline thalamus E) Ventral roots
Which of the following is NOT true about the touch pathway for the hands? Travels up the dorsal column-medial lemniscal pathway All of the answers are true O Receptors are bare nerve endings Fibers are thicker and more myelinated than receptors for pain O Decussates in the medulla
