A Moment in History

Dr. Henry J. Heimlich was born in 1920 in Wilmington, DE. He studied Medicine at Cornell University and served in the US Naval Reserve. In the early 1960's he designed a one-way valve to allow for the slow drainage of a pneumothorax or a pneumohemothorax. He is best known for the creation and world-wide known "Heimlich maneuver" to clear the upper respiratory pathways in the case of choking victims.

Infundibulum

[Infundibulum] is a Latin word and it means "funnel". The plural form is [infundibula]. Variations of the word include [infundibuliform] meaning "with the shape or form of a funnel], and [infundibular] meaning "pertaining to a funnel". This word is widely used in human anatomy and embryology:

Infundibuliform fascia: Funnel-shaped portion of the transversalis fascia that is directed toward and forming the internal inguinal ring.

Hypophyseal infundibulum: An inferior extension of the hypothalamus forming a funnel-shaped stalk connected to the hypophysis or pituitary gland. (see image)

Cystic infundibulum: The funnel-shaped portion of the gallbladder

Ethmoidal infundibulum: a funnel-shaped extension of the middle meatus of the ethmoid bone, etc.

Uterine infundibulum: Refers to the funnel-shaped distal opening of the uterine tube

The term infundibulum is also found in heart anatomy. It refers to funnel-shaped extensions of the cardiac chambers. This is well-illustrated by both the cone-like right and left ventricular outflow tracts toward the semilunar valves (aortic and pulmonary). In the case of the atrioventricular valves (tricuspid and mitral) there is also described an infundibular region. In all cases, these funnel-shaped regions allow for smooth, non-turbulent blood flow towards their respective valves.
