Exam 14: A: Central Nervous System

Cerebrospinal fluid circulates in the subarachnoid space of the meninges.

All of the functions of the cerebellum have to do with control of smooth muscle or glands.

Cerebrospinal fluid is not found in the subarachnoid space.

The shallow grooves of the cerebrum are called sulci.

The central nervous system includes all of the nervous system except the peripheral nervous system.

A lesion or tumor in the hypothalamus may cause overeating and result in substantial weight gain.

Because there is a strong link between the thalamus and emotion,it can produce symptoms of a psychosomatic disease.

The dorsal root ganglion consists of cell bodies of unipolar sensory neurons.

The hypothalamus plays an important role in maintaining proper body temperature.

The outermost protective covering of the brain is the dura mater.

The brain contains about 200 billion cells.

The "tree of life" (arbor vitae)is found in the cerebellum.

Pyramidal tracts are motor pathways that form pyramids in the medulla.

For voluntary skeletal muscle activity,impulses originate in the cerebrum but coordination of the activity is a function of the cerebellum.

The cerebellum coordinates both incoming and outgoing motor information.

Peripheral motor neuron cell bodies are located in the dorsal root ganglia of the spinal nerves.

The structure in the brain called the corpora quadrigemina is found in the midbrain.

Basal ganglia are islands of gray matter deep in the cerebellum.

The fourth ventricle in the brain is an expansion of the central canal of the spinal cord.

Meningitis refers to inflammation of the brain.
