Chapter 8, Problem 1RA
Summary Introduction
To determine:
The true statement about precentral gyrus.
Introduction:
The numerous folds and grooves that characterize the cerebral cortex are known as convolutions. An elevated fold of convolution is known as gyrus and each cerebral hemisphere is divided into various lobes, namely frontal, parietal, temporal, and occipital. The frontal lobe is the anterior portion of each cerebral hemisphere. A fissure known as central sulcus distincts the frontal lobe from the parietal lobe.

The thoracic spinal cord has the smallest dorsal horn area because:
a.
the trunk is the most innervated area of the body and therefore there are more projections into the dorsal horn there.
b.
the trunk is the least innervated area of the body and therefore there are fewer projections into the dorsal horn there.
c.
most of the descending upper motor neurons have already entered the ventral horn.
d.
There are many motor neurons to control the small muscles around the spine.
The subdivision of the brain that does not initiate somatic motor movements, but rather coordinates and fine-tunes those movements, is the a. medulla oblongata. b. cerebrum. c. cerebellum. d. diencephalon.
The major relay station for sensory input that projects to the cerebralcortex is thea. hypothalamus. d. cerebellum.b. thalamus. e. midbrain.c. pons
