cerebellum
medulla oblongata
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
Drag the function of the somatic sensory pathway to its proper location on the spinal cord.
Drag the appropriate labels to their respective targets.
