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
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
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
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. (Bickley)

D. Sacral S1-S5
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 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)

- 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 fibers commingle with similar fibers from
other levels in plexuses outside the cord, from which peripheral nerves emerge. Most
peripheral nerves contain both sensory (afferent) and motor (efferent) fibers. (Bickley)

This mediate voluntary movement and integrate skilled, complicated, or delicate movements by
stim- ulating selected muscular actions and inhibiting others. They also carry impulses that
inhibit muscle tone, the slight tension maintained by normal muscle even when it is relaxed.
(Bickley)
A. Corticospinal (pyramidal) tract
B. Basal Ganglia
C. Cerebellar system
A. Corticospinal (pyramidal) tract
- The corticospinal (pyramidal) tract. The corticospinal tracts mediate voluntary movement
and integrate skilled, complicated, or delicate movements by stimulating selected muscular
actions and inhibiting others. They also carry impulses that inhibit muscle tone, the slight
tension maintained by normal muscle even when it is relaxed. The corticospinal tracts
originate in the motor cortex of the brain (Fig. 17-6). Motor fibers travel down into the lower
medulla, where they form an anatomical structure resembling a pyramid.
- There, most of these fibers cross to the opposite or contralateral side of the medulla,
continue downward, and synapse with anterior horn cells or with intermediate neurons.
Tracts synapsing in the brainstem with motor nuclei of the CNs are termed corticobulbar.
● The basal ganglia system. This exceedingly complex system includes motor pathways
between the cerebral cortex, basal ganglia, brainstem, and spinal cord. It helps to maintain
muscle tone and to control body movements, especially gross automatic movements such as
walking.
● The cerebellar system. The cerebellum receives both sensory and motor input and
coordinates motor activity, maintains equilibrium, and helps to control posture. (Bickley)
When upper motor neuron systems are damaged above their crossover in the medulla, motor
impairment develops on and becomes (STA)
