This consists of aggregations of neuronal cell bodies. It rims the
surfaces of the cerebral hemispheres, forming the cerebral cortex
A. Gray matter
B. White matter - ANSWER-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 pituitary 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 - ANSWER-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
sections: 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 - ANSWER-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.

Determine how many segements of the ff
A. Cervical
B. Thoracic
C. Lumbar
D. Sacral - ANSWER-A. Cervical C1-C8
B. Thoracic T1-T12
C. Lumbar L1-L5
D. Sacral S1-S5
This regulates muscle movements and response to the sensations
of touch and pain
A. Somatic
B. Autonomic - ANSWER-A. Somatic
- The peripheral nervous system (PNS) consists of both CNs and
peripheral nerves that project to the heart, visceral organs, skin,
and limbs. It controls the somatic nervous system, which
regulates muscle movements and response to the sensations of
touch and pain, and the autonomic nervous system that connects
to internal organs and generates 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 parasympathetic nervous

system, which conserves energy and resources during times of
rest and relaxation."5 (Bickley)

Determine the pairs of peripheral nerves
A. Cervical
B. Thoracic
C. Lumbar
D. Sacral
E. Coccygeal - ANSWER-A. Cervical- 8
B. Thoracic- 12
C. Lumbar- 5
D. Sacral- 5
E. Coccygeal- 1
- The PNS includes spinal and peripheral nerves that carry
impulses to and from the cord. A total of 31 pairs of spinal
nerves attach to the spinal cord: 8 cervical, 12 thoracic, 5
lumbar, 5 sacral, and 1 coccygeal. Each nerve has an anterior
(ventral) root containing motor fibers, and a posterior (dorsal)
root containing sensory fibers. The anterior and posterior roots
merge to form a short spinal nerve, <5 mm long. Spinal nerve
