Frenulum

(Redirected from Frænulum)
Jump to navigation Jump to search

A frenulum (or frenum, plural: frenula or frena, from the Latin frēnulum, "little bridle", the diminutive of frēnum[1]) is a small fold of tissue that secures or restricts the motion of a mobile organ in the body.

In human anatomy

Frenula on the human body include several in the mouth, some in the digestive tract, and some connected to the external genitalia.

An overly short oral or genital frenulum may require a frenulectomy or frenuloplasty to achieve normal mobility.

In insects

The word frenulum also refers to a bristle present at the root of the hindwing of most moths which engages with a small hook or tuft on the forewing (the retinaculum) to join the wings together.
