A+
Abdomen - ANSWER The body cavity that contains the major organs of digestion
and excretion. It is located below the diaphragm and above the pelvis.
Acetabulum - ANSWER The depression on the lateral pelvis where its three
component bones join, in which the femoral head fits snugly.
Adam's apple - ANSWER A firm prominence of cartilage that forms the upper
part of the larynx. It is more prominent in men than in women. Also called the
thyroid cartilage.
Adenosine triphosphate - ANSWER The nucleotide involved in energy
metabolism; used to store energy
Adrenal glands - ANSWER Endocrine glands located on top of the kidneys that
release adrenaline when stimulated by the sympathetic nervous system.
Adrenergic - ANSWER Pertaining to nerves that release the neurotransmitter
norepinephrine, or noradrenalinel; also pertains to the receptors acted on by
norepinephrine.
,Aerobic metabolism - ANSWER Metabolism that can proceed only in the
presence of oxygen.
Agonal gasps - ANSWER Occasional, gasping breaths that occur after the heart
has stopped; seen in dying patients.
Alpha - ANSWER A type of energy that is emitted from a strong radiologic
source; it is the least harmful penetrating type of radiation and cannot travel more
than a few inches or penetrate most objects.
Alpha-adrenergic receptors - ANSWER Portions of the nervous system that,
when stimulated, can cause constriction of blood vessels
Alveloi - ANSWER The air sacs of the lungs in which the exchange of oxygen
and carbon dioxide takes place.
Anaerobic metabolism - ANSWER The metabolism that takes place in the
absence of oxygen; the main byproduct is lactic acid.
Anatomic position - ANSWER The position of reference in which the patient
stands facing forward, arms at the side, with the palms of the hands forward.
Aorta - ANSWER The main artery leaving the left side of the heart, which
receives blood from the left ventricle and delivers it to all the other arteries that
carry blood to the tissues of the body.
Appendicular skeleton - ANSWER The portion of the skeletal system that
comprises the arms, legs, pelvis, and shoulder girdle.
,Appendix - ANSWER A small, tubular structure that is attached to the lower
border of the cecum in the lower right quadrant of the abdomen.
Arterioles - ANSWER The smallest branches of arteries leading to the vast
network of capillaries.
Artery - ANSWER A blood vessel, consisting of three layers of tissue and smooth
muscle, that carries blood away from the heart.
Articular cartilage - ANSWER A pearly white layer of specialized cartilage
covering the articular surfaces (contact surfaces on the ends) of bones in synovial
joints.
Atrium - ANSWER One of two (right and left) upper chambers of the heart. The
right receives blood from the vena cava and delivers it to the right ventricle.. The
left receives blood from pulmonary veins and delivers it to the left ventricle.
Autonomic nervous system - ANSWER The part of the nervous system that
regulates involuntary activities of the body, such as heart rate, blood pressure, and
digestion of food.
Axial skeleton - ANSWER The part of the skeleton comprising the skull, spinal
column, and rib cage.
Ball-and-socket joint - ANSWER A joint that allows internal and external
rotation, as well as bending.
Beta - ANSWER A type of energy that is emitted from a strong radiologic source;
it is slightly more penetrating than alpha and requires a layer of clothing to stop it.
, Beta-adrenergic receptors - ANSWER Portions of the nervous system that, when
stimulated, can cause an increase in the force of contraction of the heart, an
increased heart rate, and bronchial dilation.
Biceps - ANSWER The large muscle that covers the front of the humerus.
Bile ducts - ANSWER The ducts that convey bile between the liver and the
intestine
Blood pressure - ANSWER The pressure that the blood exerts against the walls of
the arteries as it passes through them.
Brachial artery - ANSWER The major vessel in the upper extremities that
supplies blood to the arm.
Brain - ANSWER The controlling organ of the body and center of consciousness;
functions include perception, controls of reactions to the environment, emotional
responses, and judgement.
Brain stem - ANSWER The area of the brain between the spinal cord and
cerebrum, surrounded by the cerebellum; controls functions that are necessary for
life, such as respiration.
Capillary vessels - ANSWER The tiny blood vessels between the arterioles and
venules that permit transfer of oxygen, carbon dioxide, nutrients, and waste
between body tissues and the blood.
Cardiac muscle - ANSWER The heart muscle.
