Question
Chapter 10.5, Problem 20CC
Summary Introduction
To determine: The reason due to which somatosensory information is projected to only one hemisphere of the brain; whereas, the auditory information is projected to both the hemispheres of the brain.
Introduction: The somatosensory cortex is involved in receiving and processing the information from the sensory neurons. The neurons, which sense the feelings in skin, pain, vision, and auditory stimuli, send their signals to the somatosensory cortex.

Describe and draw the spinocerebellar pathway, dorsal column-medial lemniscal pathway, spinothalamic pathway, and the lateral (pyramidal) corticospinal pathway for the transmission of information associated with the right foot. What information is transmitted by each pathway? (All pathways should be clearly illustrated on the same figure. You may take a picture of your artwork and paste it into your word document.)
Please label the following structures associated with the somatosensory pathway. Thank you!
Unilateral Cerebral strokes can cause deficits in motor control, somatic
sensation and vision. However, they do not cause deficits in hearing. The
explanation for this is:
Auditory information does not reach the cortex
Auditory information only goes to one hemisphere.
Auditory information goes to both hemispheres
How are the outer segments of photoreceptors positioned?
between bipolar cells and horizontal cells
in the outermost layer of the retina
in the ganglion cell layer
farthest from the pigment epithelium

- The thalamus has been described as a “switchboard.” Explain why, by describing the pathway of somatic sensory information from the receptors to the cerebral cortex. Case Study: Princess Leia has asthma, and had to use her inhaler before taking her physiology exam. Later, in the physiology laboratory, she measured her pulse rate and blood pressure and found them to be higher than usual. The following week, after administering some drugs (epinephrine, atropine) she later developed a severe headache and dry mouth. When she looked in the mirror she noticed that her pupils were dilated.arrow_forwardThe thalamus has been described as a “switchboard.” Explain why, by describing the pathway of somatic sensory information from the receptors to the cerebral cortex.arrow_forwardCertain postganglionic neurons cause the pupil of the eye to constrict by releasing what chemical neurotransmitter?

- If a human suffers a hand amputation as an adult, what will happen to the area of the somatosensory cortex that previously received information from the lost hand? The projections from the hand will still be there, but will be inactive. The projections from the hand will die, and that area of the cortex will be empty. Projections from the face and neighboring limb will expand to control that cortical area. That cortical area will die.arrow_forwardWhat is a sensory modality?arrow_forward1) What is the general pathway of sensory information from the sensory receptor to the cerebral corțex or cerebellum?arrow_forward
