Anatomy
There are several frenula in the human body, including the frenulum of prepuce of penis, frenulum of labia minora, frenulum of tongue, and frenulum of lower lip. Each frenulum serves a unique function in the body, primarily to restrict the movement of the organ it is attached to.
Frenulum of prepuce of penis
The frenulum of prepuce of penis is a band of tissue located on the underside of the penis. It connects the foreskin to the vernal mucosa, and helps to contract the foreskin over the glans.
Frenulum of labia minora
The frenulum of labia minora is situated at the posterior junction of the labia minora. It is a fold of skin that secures the labia minora in place.
Frenulum of tongue
The frenulum of tongue, also known as the lingual frenulum, is a fold of mucous membrane that anchors the tongue to the floor of the mouth. It aids in the movement and function of the tongue.
Frenulum of lower lip
The frenulum of lower lip is a small fold of mucous membrane that connects the inside of the lower lip to the gum. It helps to control the movement of the lower lip.
