Chapter 19 - Gross Anatomy of the Brain and Cranial Nerves Flashcards

Consist of nerve fibers the conduct impulses TOWARD the CNS.

Consists of nerve fibers that conduct impulses AWAY from the CNS.

Sometimes called the voluntary system.
Controls skeletal muscles.

Efferent division of the peripheral nervous system that innervates cardiac and smooth muscles and glands; also called the involuntary or visceral motor system.

The division of the autonomic nervous system that prepares the body for activity or to cope with some stressor (danger, excitement, etc.); the fight, fright, and flight subdivision.

The division of the autonomic nervous system that oversees digestion, elimination, and glandular function; the resting and digesting subdivision.

The most superior portion of the brain.
Consist of gyri and sulci.
Divided into left and right hemispheres the into lobes.

An outward fold of the surface of the cerebral cortex.

A furrow on the brain, less deep than a fissure.

The deepest depressions or inward folds on the brain.

Divide brain into left and right hemisperes.

Seperates the temporal lobe from the parietal lobe.

Divides the frontal lobe from the parietal lobe.

That part of the forebrain between the cerebral hemispheres and the midbrain including the thalamus, the epithalamus, and the hypothalamus.

Enlargements at the terminus of the olfactory nerve at the base of the brain just above the nasal cavities.

The partial crossover of fibers of the optic nerves.

A mass of gray matter in the diencephalon of the brain.

Region of the diencephalon forming the floor of the third ventricle of the brain.

Neuroendocrine gland located beneath the brain that serves a variety of functions including regulation of gonads, thyroid, adrenal cortex, lactation, and water balance.

Along with the anterior and dorsomedial nuclei in the thalamus, are involved with the processing of recognition memory.

Most dorsal portion of the diencephalon; forms the roof of the third ventricle with the pineal gland extending from its posterior border.

A hormone-secreting part of the diencephalon of the brain thought to be involved in setting the biological clock and influencing reproductive function.

A capillary knot that protrudes into a brain ventricle; involved in forming cerebrospinal fluid.

A broad band of nerve fibers joining the two hemispheres of the brain.

Collectively the midbrain, pons, and medulla of the brain.

A bundle of myelinated neurons joining different parts of the brain.

the part of the brain stem connecting the medulla with the midbrain, providing linkage between upper and lower levels of the central nervous system.

Inferiormost part of the brain stem.

Part of the copora quadrigemina

Part of the copora quadrigemina

The arborescent appearance of the white matter in a vertical section of the cerebellum.

Protective coverings of the central nervous system; from the most external to the most internal, the dura mater, arachnoid mater, and pia mater.

Outermost and toughest of the three membranes (meninges) covering the brain and spinal cord.

The middle layer of the three meninges.

Innermost layer of the meninges.

The 12 nerve pairs that arise from the brain.
