left atrioventricular valve (medicine) and phobia (medicine)


left atrioventricular valve (medicine)


left atrioventricular valve -->
mitral valve
<anatomy, cardiology> The heart valve that divides the left atrium and left ventricle. During left atrial contraction, the mitral valve opens to allow blood to flow into the left ventricle. Upon closure, the mitral valve prohibits the regurgitation of blood back into the left atrium. The mitral valve is the only heart valve that has only 2 valve cusps (all others have 3).


phobia (medicine)


phobia
<psychology> A persistent, irrational, intense fear of a specific object, activity or situation (the phobic stimulus), fear that is recognised as being excessive or unreasonable by the individual himself.

When a phobia is a significant source of distress or interferes with social functioning, it is considered a mental disorder, phobic disorder (or neurosis). In DSM III phobic disorders are subclassified as agoraphobia, social phobias and simple phobias. Used as a word termination denoting irrational fear of or aversion to the subject indicated by the stem to which it is affixed.

Origin: Gr. Phobos = fear
