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. (Bickley)

AND ANSWERS GRADED A+

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. (Bickley)

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. (Bickley)

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)

Determine the pairs of peripheral nerves

A. Cervical

B. Thoracic

C. Lumbar

D. Sacral

E. Coccygeal

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 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)

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 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. 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, espe- cially 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)

A. Ipsilateral

B. Contralateral

C. Exaggerated reflex

D. Lack of reflex

B. Contralateral & C. Exaggerated reflex

  • When upper motor neuron systems are dam- aged above their crossover in the medulla, motor impairment develops on the opposite or contralateral side. In damage below the crossover, motor impairment occurs on the same or ipsi- lateral side of the body (Bickley)
  • slow- ness or lack of spontaneous and automatic movements termed bradykinesia, and various involuntary movements. (Bickley)

  • Impaired strength or weakness is called paresis. Absent strength is paralysis, or plegia. Hemiparesis refers to weakness of one half of the body; hemiplegia refers to paralysis of one half of the body. Paraplegia means paralysis of the legs; quadriplegia means paralysis of all four limbs.

B. symmet- ric weakness of distal muscles sug- gests

A. Myopathy

B. Polymyopathy

  • ■ The vestibular system, for balance and for coordinating eye, head, and body movements

■ The sensory system, for position sense

  • In cerebellar disease, instead of alter- nating quickly, these movements are slow, irregular, and clumsy, an abnor- mality called dysdiadochokinesis. Upper motor neuron weakness and basal ganglia disease can also impair these movements, but not in the same manner.
  • Dysdiadochokinesis points to cerebellar disease.
