| milk ejection | Reflex in which tactile stimulation of nipples causes release of oxytocin which causes myoepithelial cells surrounding mammary alveoli to contract and expel the milk. Applies to humans and animals. (12 Dec 1998) |
|---|---|
| milk-ejection reflex | Release of milk from the breast following tactile stimulation of the nipple; the afferent path is postulated to exist from the nipple to the hypothalamus; the efferent limb is represented by the neurohypophysial release of oxytocin into the systemic circulation; contraction of myoepithelial elements within the breast, caused by oxytocin, moves milk into the collecting ducts and toward the nipple. Synonym: let-down reflex, milk let-down reflex. (05 Mar 2000) |
| ejection | 1. The act of ejecting or casting out; discharge; expulsion; evacuation. "Vast ejection of ashes." . "The ejection of a word." 2. <physiology> The act or process of discharging anything from the body, particularly the excretions. 3. The state of being ejected or cast out; dispossession; banishment. Origin: L. Ejectio: cf. F. Ejection. Source: Websters Dictionary (01 Mar 1998) |
| ejection fraction | <cardiology> A measure of ventricular contractility, equal to normally 65 |
| ejection murmur | A diamond-shaped systolic murmur produced by the ejection of blood into the aorta or pulmonary artery and ending by the time of the second heart sound component produced, respectively, by closing of the aortic or pulmonic valve. (05 Mar 2000) |
| ejection period | The period in the cardiac cycle when the semilunar valves are open and blood is being ejected from the ventricles into the arterial system. Synonym: ejection period. (05 Mar 2000) |
| ejection sounds | Click-like sounds during ejection from a hypertensive aorta or pulmonary artery or associated with stenosis (particularly congenital) of the aortic or pulmonic valve. (05 Mar 2000) |
| left ventricular ejection time | The time measured clinically from onset to incisural notch of the carotid or other pulse; properly the time of ejection of blood from the left ventricle beginning with aortic valve opening and ending with aortic valve closure. (05 Mar 2000) |
| cardiac valvular incompetence | Failure of a valve to perform its fundamental function: insurance of one-way flow; manifested by regurgitation of blood in the opposite direction when the valve is supposed to be closed. (05 Mar 2000) |
| valvular | 1. <medicine> Of or pertaining to a valve or valves; specifically, of or pertaining to the valves of the heart; as, valvular disease. 2. Containing valves; serving as a valve; opening by valves; valvate; as, a valvular capsule. Origin: Cf. F. Valvulaire. Source: Websters Dictionary (01 Mar 1998) |
| valvular aortic stenosis | <radiology> Secondary to fusion of commisures between cusps types: bicuspid/unicuspid (95%): in 1-2% of population; M>F; commonly associated with coarctation, tricuspid (5%), dysplastic thickened aortic cusps in infants with crtical aortic stenosis: may stimulate neonatal sepsis, associated with L-R shunts (atrial septal defect, VSD), marked CMG (thickened wall of LV), pulmonary venous hypertension, congestive heart failure child/adult: LV configuration with normal heart size, postenotic dilatation, calcified valve (60% of patients greater than24 y.o.) see: aortic stenosis (12 Dec 1998) |
| valvular endocarditis | Inflammation confined to the endocardium of the valves. (05 Mar 2000) |
| valvular heart disease | A general term that applies to any abnormality of one of the heart valves, tricuspid, mitral, aortic or pulmonic valves. (27 Sep 1997) |
| valvular incompetence | A leaky state of one or more of the cardiac valves, the valve not closing tightly and blood therefore regurgitating through it. Synonym: valvular incompetence, valvular insufficiency. (05 Mar 2000) |
| valvular insufficiency | A leaky state of one or more of the cardiac valves, the valve not closing tightly and blood therefore regurgitating through it. Synonym: valvular incompetence, valvular insufficiency. (05 Mar 2000) |
