stimulus

anything that excites (activates) a nerve and causes an impulse (plural, stimuli). An impulse is a wave of excitation transmitted through nerve fibers and neurons.

89
Q

reflex

A

an automatic, involuntary response to some change, either inside or outside the body

90
Q

Neurons

A

the basic cells of the nervous system that allow different parts of the body to communicate with each other

91
Q

Afferent neurons

A

Also known as sensory neurons, these neurons emerge from sensory organs and the skin to carry the impulses from the sensory organs toward the brain and spinal cord.

92
Q

Connecting neurons

A

Also known as associative neurons, these neurons link afferent and efferent neurons.

93
Q

Efferent neurons

A

Also known as motor neurons, these neurons carry impulses away from the brain and spinal cord and toward the muscles and glands.

94
Q

dendrites

A

the root-like processes that receive impulses and conduct them to the cell body. A process is a structure that extends out from the cell body.

95
Q

axon

A

a process that conducts impulses away from the nerve cell. An axon can be more than 3 feet long. Many, but not all, axons are protected by a myelin sheath, which is a white fatty tissue covering.

96
Q

Terminal end fibers

A

the branching fibers at the end of the axon that lead the nerve impulse from the axon to the synapse.

97
Q

synapse

A

the space between two neurons or between a neuron and a receptor organ. A single neuron can have a few or several hundred synapses.

98
Q

Glial cells

A

provide support and protection for neurons, and their four main functions are

(1) to surround neurons and hold them in place,
(2) to supply nutrients and oxygen to neurons,
(3) to insulate one neuron from another, and
(4) to destroy and remove dead neurons.

99
Q

myelin sheath

A

the protective covering made up of glial cells. This white sheath forms the white matter of the brain and covers some parts of the spinal cord and the axon of most peripheral nerves

100
Q

meninges

A

the system of membranes that enclose the brain and spinal cord (singular, meninx). The meninges consist of three layers of connective tissue. These are the dura mater, the arachnoid membrane, and the pia mater

101
Q

arachnoid membrane

A

which resembles a spider web, is the second layer of the meninges and is located between the dura mater and the pia mater.

102
Q

pia mater

A

which is the third layer of the meninges, is located nearest to the brain and spinal cord. It consists of delicate connective tissue that contains a rich supply of blood vessels.

103
Q

Cerebrospinal fluid

A

also known as spinal fluid, is produced by special capillaries within the four ventricles located in the middle region of the cerebrum. It is a clear, colorless, watery fluid that flows throughout the brain and around the spinal cord. The functions of this fluid are to:

Cool and cushion these organs from shock or injury.

Nourish the brain and spinal cord by transporting nutrients and chemical messengers to these tissues.

104
Q

cerebrum

A

the largest and uppermost part of the brain, consists of four lobes. Controls the highest level of thought, including judgment, memory, association, and critical thinking. It also processes sensations and controls all voluntary muscle activity.

105
Q

thalamus

A

located below the cerebrum. Relays sensory stimuli from the spinal cord and midbrain to the cerebral cortex. The thalamus suppresses some stimuli and magnifies others.

106
Q

hypothalamus

A

located below the thalamus; Controls 7 vital bodily functions

107
Q

cerebellum

A

located in the lower back of the cranium below the cerebrum. Coordinates muscular activity and balance for smooth and steady movements.

108
Q

brainstem

A

located in the base of the brain and forms the connection between the brain and spinal cord. It consists of the:

midbrain

pons

medulla oblongata;
Controls the functions necessary for survival (breathing, digestion, heart rate, and blood pressure) and for arousal (being awake and alert).

109
Q

cerebral

A

pertaining to the cerebrum or to the brain

110
Q

cerebral cortex

A

made up of gray matter, is the outer layer of the cerebrum and is made up of elevated folds and deep fissures.

Gyri are the elevated folds of gray matter in the cerebral cortex (singular, gyrus).

Sulci are the fissures of the cerebral cortex (singular, sulcus). As used here, a fissure is a normally occurring deep groove.

111
Q

cerebral hemispheres

A

connected at the lower midpoint by the corpus callosum.

The left cerebral hemisphere controls the majority of functions on the right side of the body. An injury to the left hemisphere produces sensory and motor deficits on the right side of the body.

The right cerebral hemisphere controls most of the functions on the left side of the body. An injury to the right hemisphere produces sensory and motor deficits on the left side of the body.

The crossing of nerve fibers that makes this arrangement possible occurs in the brainstem

112
Q

cerebral lobes

A

Each lobe is named for the bone of the cranium that covers it.

The frontal lobe controls skilled motor functions, memory, and behavior.

The parietal lobe receives and interprets nerve impulses from sensory receptors in the tongue, skin, and muscles.

The occipital lobe controls eyesight.

The temporal lobe controls the senses of hearing and smell, and the ability to create, store, and access new information.

113
Q

midbrain & pons

A

provide conduction pathways to and from the higher and lower centers in the brain. They also control reflexes for movements of the eyes and head in response to visual and auditory stimuli

114
Q

medulla oblongata

A

which is located at the lowest part of the brainstem, is connected to the spinal cord. It controls basic survival functions, including the muscles that make possible respiration, heart rate, and blood pressure, as well as reflexes for coughing, sneezing, swallowing, and vomiting

115
Q

spinal cord

A

a long, fragile, tube-like structure that begins at the end of the brainstem and continues down almost to the bottom of the spinal column.

The spinal cord contains all the nerves that affect the limbs and lower part of the body, and serves as the pathway for impulses traveling to and from the brain.
