Sulcus grooves on brain surface
Gyrus ridge of tissue bound between two sulci or between a sulcus and a fissure. (57)
Adjacent gyri appear to be separated, but the s

All extra-ocular muscles except the superior oblique and the lateral rectus are supplied by cranial nerve III.
The three rectus muscles supplied by cranial III are the medial, superior, and inferior rectus.

As one examines sections at higher and higher cord levels, the posterior white columns becomes
The posterior white column on each side at the lumbar level contains only fasciculus gracilis.
Neuroanatomy Sidman & Sidman Section D
The portion of a spinal nerve within the vertebral column elongates as the vertebral column elongates.
A nerve root is the portion of a nerve that extends from the spinal cord to the exit point between 2 vertebrae.
Neuroanatomy Sidman & Sidman Section C
The amygdala lies in the temporal lobe. The lenticular nucles does not.
The corticospinal fibers pass lateral to the caudate nucleus. Further down, as part of the posterior limb of
the internal capsule, the corticos
Neuroanatomy Sidman & Sidman Section B
Like the lenticular nucleus, the outermost part of the pre-central gyrus is gray matter. The internal capsule is
white matter, for it contains axons with myelin sheaths.
Fibers of the internal capsule which terminat

French anatomist, Francois Sylvius (17th century) first recognized the Sylvian fissure as a horizontal
cleavage separating the temporal lobe below
