Anatomy & Physiology Chapter 13 Central Nervous System

Front 1

Name the three membranous coverings of the central nervous system in order, beginning with the outermost layer

Back 1

Dura mater, arachnoid membrane, and pia mater.

Front 2

What are spinal nerve roots? How does the dorsal root differ from the ventral root?

Back 2

Bundles of nerve fibers tht project from each side of the spinal cord. The dorsal root carries sensory information, whereas the ventral root carries motor information

Front 3

Brain Stem

Back 3

part of brain containing the midbrain, pons, and medulla oblongata

Front 4

Cerebellum

Back 4

second largest part of the human brain; plays an essential role in the production of normal movements

Front 5

Cerebrospinal Fluid (CSF)

Back 5

plasma-like fluid that fills the subarachnoid space in the brain and spinal cord and in the cerebral ventricles

Front 6

Cerebrum

Back 6

largest and uppermost part of the human brain that controls consciousness, memory, sensations, emotions, and voluntary movements

Front 7

Diencephalon

Back 7

“between” brain; parts of the brain between the cerebral hemispheres and the mesencephalon, or midbrain

Front 8

Electroencephalogram

Back 8

graphic representation of voltage changes in brain tissue used to evaluate nerve tissue function

Front 9

Hypothalmus

Back 9

important autonomic and neuroendocrine control center located inferior to the thalamus in the brain

Front 10

Limbic System

Back 10

parts of the brain involved in emotions and sense of smell; plays key role in coupling sensory inputs to short- and long-term memor

Front 11

Meninges

Back 11

fluid-containing membranes surrounding the brain and spinal cord

Front 12

Plexus

Back 12

complex network formed by converging and diverging nerves, blood vessels, or lymphatics

Front 13

Reticular Formation

Back 13

located in the medulla where bits of gray and white matter mix intricately; this structure is involved in regulating input from sensory neurons, arousal, and motor control

Front 14

Spinal nerve

Back 14

nerve that connects the spinal cord to peripheral structures such as the skin and skeletal muscles

Front 15

Thalamus

Back 15

mass of gray matter located in diencephalon just above the hypothalamus; helps produce sensations, associates sensations with emotions, and plays a part in the arousal mechanism

Front 16

ventricles

Back 16

such as the large, fluid-filled spaces within the brain or the chambers of the heart
