Chapter 6: The Human Body Flashcards
Abdomen
The body cavity that contains many of the major organs of digestion and excretion. It is located below the diaphragm and above the pelvis.
Acetabulum
The depression on the lateral pelvis where it’s three component bones join, in which the femoral head fits snuggly.
Adenosine tri phosphate (ATP)
The nucleotide involved in energy metabolism; used to store energy.
Adrenal glands
Endocrine glands located on the top of the kidneys that release adrenaline when stimulated by the sympathetic nervous system.
Andrenergic
Pertaining to nerves I release the neurotransmitter norepinephrine
, or noradrenaline(e.g. andrenergic nerves, andrenergic response); Also pertain to the receptors acted on by norepinephrine.
Aerobic metabolism
Metabolism that can proceed only in the presence of oxygen.
Agonal gasps
Abnormal breathing pattern characterized by slow, Gasping breaths, sometimes seen in patients in cardiac arrest.
Alpha adrenergic receptors
Portions of the nervous system that, when stimulated, can cause constriction of blood vessels.
Alveoli
The air sacs of the lungs in which the exchange of oxygen and carbon dioxide takes place.
Anaerobic metabolism
Metabolism that takes place in the absence of oxygen; the main byproduct is lactic acid.
Anatomic position
The position of reference in which the patient stands Facing forward, arms at the side, with the palms of the hands forward.
Anatomy
The study of the physical structure of the body and its components.
Aorta
The main artery leaving the left side of the heart and caring freshly oxygenated blood to the body.
Appendix
A small, tubular structure that is attached to the lower border of the cecum in the lower right quadrant of the abdomen.
Appendicular skeleton
The portion of the skeletal system that comprises the arms, legs, pelvis, and the shoulder girdle. 
Arterioles
The smallest branches of arteries leading to the vast network of capillaries
Articular cartilage
Pearly layer of specialized cartilage covering the articular surfaces (contact surfaces on the ends of bones) in synovial joints
Atrium
One of the two upper chambers of the heart.
Autonomic nervous system
The part of the nervous system regulates functions, such as digestion and sweating, that are not controlled voluntarily.
Axial skeleton
The part of the skeleton comprising the school, vertebral column, and rib cage.
Axons
Extensions of a neuron that carry impulses away from the nerve cell body to the dendrites of another neuron.
Ball and socket joint
A joint that allows internal and extra rotation, as well as bending.
beta-andrenergic receptors
Portions of the nervous system that, when stimulated, can cause an increase in the force of contraction of the heart, and increased heart rate, and bronchial dilation.
Biceps
The large muscle that covers the front of the humerus.
