Anatomy & Physiology Flashcards
Abductor
A muscle that separates the fingers and toes
Abductor digiti minimi
A muscle of the foot that separates the toes
Abductor hallucis
Muscle of the foot that moves the big toe and helps maintain balance while walking or standing
Adductor
Muscle at the base of each finger that draws fingers together
Adenosine triphosphate
Chemical energy used for metabolism
Adipose tissue
Fat; gives smoothness and contour to the body
Adrenal glands
Glands that control metabolic processes of the body, including fight or flight response
Anabolism
Constructive metabolism , combining smaller molecules to build larger and more complex molecules
Anatomy
Study of human body structures, as well as what the body is made up of, science of structure of organisms or of their parts
Anterior tibial artery
Supplies blood to lower leg muscles and to muscles and skin on the top of the foot and sides of first and second toes, goes to the foot and becomes dorsalis pedis artery
Aorta
Largest artery in the body, carries oxygenated blood from the heart to be distributed by branch arteries throughout the body
Artery
Thick walled muscular and flexible tubes that carry oxygenated blood from heart to capillaries
Atrium
One of the two upper chambers of the heart, through which blood is pumped to the ventricles
Autonomic Nervous System
Part of the nervous system that controls involuntary muscles and regulates the action of the smooth muscles, glands, blood vessels and heart
Bicep
Muscle producing contour of the front and inner side of upper arm, it lifts the forearm and flexes the elbow
Blood
Nutritive fluid circulating through the circulatory system(heart, veins, arteries and capillaries) to supply oxygen and nutrients to cells and tissues and to remove carbon dioxide and waste from them
Blood vascular system
Group of structures ( heart, arteries, veins, capillaries) that distribute blood throughout the body
Body system
11 major systems, group of bodily organs acting together to perform one or more functions
Brain
Part of central nervous system contained in cranium, largest and most complex nerve tissue, controls sensation, muscles, gland activity and the power to think and feel emotions
Capillary
Tiny thin walled blood vessel that connects the smaller arteries to the veins
Cardiac muscle
Involuntary muscle that is the heart, only found in the heart
Carpus
The wrist, a flexible joint composed of a group of 8 small irregular bones held together by ligaments
Catabolism
Phase of metabolism in which larger, more complex molecules are broken down to create simpler molecules
Cell membrane
Cell part that encloses and holds the protoplasm while still allowing soluble substances (nutrients or waste by products) to enter or leave the cell
