Abdominal quadrants
four divisions of the abdomen used to pinpoint the location of pain or injury: the right upper quadrant (RUQ), the left upper quadrant (LUQ), the right lower quadrant (RLQ), and the left lower quadrant (LLQ).
Acetabulum
The pelvic socket into which the ball at the proximal end of the femur fits to form the hip joint.
Acromioclavicular joint
The joint where the acromion and the clavicle meet
Acromion Process
The highest portion of the shoulder.
Alveoli
The microscopic sacs of the lungs where gas exchange with the bloodstreams takes place.
Anatomical position
The standard reference position for the body in the study of anatomy. In this position, the body is standing erect, facing the observer, with arms down at the sides and the palms of the hands forward.
Anatomy
The study of body structure
Anterior
The front of the body or body part.
Aorta
The largest artery in the body. It transports blood from the left ventricle to begin systemic circulation.
Appendix
a small tube located near the junction of the small and large intestines in the right lower quadrant of the abdomen, the function of which is not well understood, its inflammation, called appendicitis, is a common cause of abdominal pain.
Arteriole
The smallest kind of artery.
Artery
Any blood vessel carrying blood away from the heart.
Atria
the two upper chambers of the heart. There is a right atrium (Which receives unoxygenated blood returning from the body) and a left atrium ( which receives oxygenated blood returning from the lungs).
Automaticity
The ability of the heart to generate and conduct electrical impulses on its own.
Autonomic nervous system
The division of the peripheral nervous system that controls involuntary motor functions.
Bilateral
on both sides.
Bladder
The round sac-like organ of the renal system used as a reservoir for urine.
Blood pressure
The pressure caused by blood exerting force against the walls of blood vessels. Usually arterial blood pressure (the pressure in the artery) is measured. There are two types: diastolic blood pressure and systolic blood pressure.
Brachial artery
Artery of the upper arm; the site of the pulse checking during infant CPR.
Bronchi
The two large sets of branches that come off the trachea and enter the lungs. There are right and left bronchi. Singular bronchus.
Calcaneus
The heel bone
Capillary
A thin-walled, microscopic blood vessel where the oxygen/carbon dioxide and nutrient/waste exchange with the body’s cells takes place.
Cardiac conduction system
A system of specialized muscle tissues that conduct electrical impulses that stimulate the heart beat.
Cardiac muscle
Specialized involuntary muscle found only in the heart.
