This consists of aggregations of neuro- nal cell bodies. It rims
the surfaces of the cerebral hemispheres, forming the cerebral
cortex
A. Gray matter
B. White matter
A. Gray matter
- Deep in the brain lie additional clusters of gray matter (Fig. 17-
2). These include the basal ganglia, which affect movement, and
the thalamus and the hypothala- mus structures in the
diencephalon. The thalamus processes sensory impulses and
relays them to the cerebral cortex. The hypothalamus maintains
homeostasis (Bickley)
- and regulates temperature, heart rate, and blood pressure. The
hypothalamus affects the endocrine system and governs
emotional behaviors such as anger and sexual drive. Hormones
secreted in the hypothalamus act directly on the pitu- itary gland.

This consists of neuronal axons that are coated with myelin. The
myelin sheaths, which create the white color, allow nerve
impulses to travel more rapidly.
A. Gray matter
B. White matter
B. White matter
- The internal capsule is a white-matter structure where
myelinated fibers converge from all parts of the cerebral cortex
and descend into the brainstem. The brainstem, which connects
the upper part of the brain with the spinal cord, has three sec-
tions: the midbrain, the pons, and the medulla. (Bickley)

Consciousness relies on the interaction between intact cerebral
hemispheres and a structure in the diencephalon and upper
brainstem
A. Reticular activating system
B. Cerebellum
A. Reticular activating system
- Consciousness relies on the interaction between intact
cerebral hemispheres and a structure in the diencephalon and
upper brainstem, the reticular activating (arousal) system.
- The cerebellum, which lies at the base of the brain, coordinates
all movement and helps maintain the body upright in space.

This regulates muscle movements and response to the
sensations of touch and pain
A. Somatic
B. Autonomic
A. Somatic
- The peripheral nervous system (PNS) consists of both CNs and
periph- eral nerves that project to the heart, visceral organs,
skin, and limbs. It controls the somatic nervous system, which
regulates muscle move- ments and response to the sensations
of touch and pain, and the autonomic nervous system that
connects to internal organs and gener- ates autonomic reflex
responses. The autonomic nervous system consists of the
sympathetic nervous system, which "mobilizes organs and their
functions during times of stress and arousal, and the para-
sympathetic nervous system, which conserves energy and
resources during times of rest and relaxation."5 (Bickley)
