  hair biology - hair follicle infundibulum, isthmus, and suprabulbar region
The upper segment extends from the entrance of the sebaceous gland duct to the follicular orifice and is called the infundibulum.
Therefore the infundibulum is that part of the hair follicle that extends from the epidermis to the opening of the sebaceous gland duct.
The nuclei of the central cells of the isthmus undergo pyknosis (a thickening, especially degeneration of a cell in which the nucleus shrinks in size and the chromatin condenses to a solid, structure less mass) before the tip of the root sheath reaches the area.

 Patent 6,897,238   (Site not responding. Last check: 2007-11-05)
Since both plugging of the infundibulum and high sebaceous gland activity are necessary for an acne lesion to develop, it is likely that two of the predisposing factors for the follicles which become infected are (1) an infundibulum shape which is easily plugged, and/or (2) a hyperactive sebaceous gland.
A sufficient amount of the ALA infiltrates spaces about the infundibulum and the infundibulum is exposed to sufficient energy to cause the converted ALA to become photodynamically activated, thereby modifying the opening to the infundibulum.
In one embodiment, the opening to the infundibulum is altered such that pore pluggage will not occur, e.g., the infundibulum is reshaped such that excess sebum, oils, dirt and bacteria will not cause pore pluggage to occur, resulting in a flhead (comedon) or white head (milium).

 Pharyngula::How do octopus suckers work?
There are two main regions, an infundibulum (IN) on the attachment face of the sucker, and a deeper chamber called the acetabulum (A) (if you don't recall any Latin, "infundibulum" just means "funnel", while "acetabulum" is "vinegar cup"—anatomy is littered with funnels and cup-shaped structures, so these are actually very generic names).
Since the infundibulum is sealed against a surface, water can't get in; so we have the same quantity of water in a larger chamber, which means the pressure is reduced, generating suction.
The infundibulum is encircled by a rim of loose epithelium (E) that is separated from the infundibulum by a narrow groove.
