Frenulum
A frenulum (or frenum, plural: frenula or frena, from the Latin ''frēnulum'', "little bridle", the diminutive of ''frēnum'') is a small fold of tissue that secures 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. *Brain: ''Frenulum of superior medullary velum'' or ''frenulum veli'' *Digestive tract: ''frenulum valvae ileocaecalis'' *Oral tissue: Frenula of the mouth include the '' frenulum linguae'' under the tongue, the '' frenulum labii superioris'' inside the upper lip, the '' frenulum labii inferioris'' inside the lower lip, and the buccal frena which connect the cheeks to the gum. These can easily be torn by violent blows to the face or mouth, thus a torn frenulum is sometimes a warning sign of physical abuse. *Penile tissue: The word ''frenulum'' on its own is often used for the frenulum of prepuce of penis or ''frenulum pr ...

Frenulum Of Tongue
The frenulum of tongue or tongue web (also lingual frenulum or frenulum linguæ; also fraenulum) is a small fold of mucous membrane extending from the floor of the mouth to the midline of the underside of the tongue. Development The tongue starts to develop at about four weeks. The tongue originates from the first, second, and third pharyngeal arches which induces the migration of muscles from the occipital myotomes. A U-shaped sulcus develops in front of and on both sides of the oral part of the tongue. This allows the tongue to be free and highly mobile, except at the region of the lingual frenulum, where it remains attached. Disturbances during this stage cause tongue tie or ankyloglossia. During the sixth week of gestation, the medial nasal processes approach each other to form a single globular process that in time gives rise to the nasal tip, columella, prolabium, frenulum of the upper lip, and the primary palate. As the tongue continues to develop, frenulum cells underg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frenulum Of Prepuce Of Penis
The frenulum of prepuce of penis, often known simply as the frenulum, is a highly erogenous elastic band of tissue under the glans penis that connects the foreskin to the vernal mucosa, and helps contract the foreskin over the glans. Along with the ridged bands at the tip of the foreskin, it is considered to be the most sensitive part of the penis to fine-touch. In the event of frenulum breve or frenular chordee, or to ensure that the glans can be freely and completely exposed, the frenulum may be partially or totally removed in a procedure known as frenulectomy. Sensitivity The frenulum and the associated tissue delta on the underside of the penis below the corona has been described in sexuality textbooks as "very reactive" and "particularly responsive to touch that is light and soft". The "underside of the shaft of the penis, meaning the part below the corona" is a "source of distinct pleasure". Crooks and Baur observe that two extremely sensitive specific locations that ma ...

Frenulum Breve
A frenulum (or frenum, plural: frenula or frena, from the Latin ''frēnulum'', "little bridle", the diminutive of ''frēnum'') is a small fold of tissue that secures 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. *Brain: ''Frenulum of superior medullary velum'' or ''frenulum veli'' *Digestive tract: ''frenulum valvae ileocaecalis'' *Oral tissue: Frenula of the mouth include the '' frenulum linguae'' under the tongue, the '' frenulum labii superioris'' inside the upper lip, the '' frenulum labii inferioris'' inside the lower lip, and the buccal frena which connect the cheeks to the gum. These can easily be torn by violent blows to the face or mouth, thus a torn frenulum is sometimes a warning sign of physical abuse. *Penile tissue: The word ''frenulum'' on its own is often used for the frenulum of prepuce of penis or ''frenulum preput ...

Frenulum Labii Inferioris
The inferior labial frenulum, or ''frenulum labii inferioris'' ( Latin, meaning "little bridle of the lower lip"). is the frenulum connecting the lower gums with the lower lip. Function The inferior labial frenulum, alongside the superior labial frenulum, provides stability to the upper and lower lip. Medical Conditions Absence of the inferior labial frenulum and/or the lingual frenulum is associated with the classical and hypermobility types of Ehlers-Danlos syndrome, but can also be absent in those without any underlying medical conditions. Tearing of the inferior labial frenulum may occur after being bit, especially after a fall, resulting in bleeding and pain. Treatment can normally be done at home, and usually heals on its own within 3–4 days. Tearing of the inferior labial frenulum may be a sign of domestic abuse.

Foreskin
In male human anatomy, the foreskin, also known as the prepuce, is the double-layered fold of skin, mucosal and muscular tissue at the distal end of the human penis that covers the glans and the urinary meatus. The foreskin is attached to the glans by an elastic band of tissue, known as the frenulum. The outer skin of the foreskin meets with the inner preputial mucosa at the area of the mucocutaneous junction. The foreskin is mobile, fairly stretchable and sustains the glans in a moist environment. Except for humans, a similar structure, known as penile sheath, appears in the male sexual organs of all primates and the vast majority of mammals. In humans, foreskin length varies widely and coverage of the glans in a flaccid and erect state can also vary. The foreskin is fused to the glans at birth and is generally not retractable in infancy and early childhood. Inability to retract the foreskin in childhood should not be considered a problem unless there are other symp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frenulectomy
A frenectomy is the removal of a frenulum, a small fold of tissue that prevents an organ in the body from moving too far. It can refer to frenula in several places on the human body. It is related to frenuloplasty, a surgical alteration in a frenulum. Done mostly for orthodontic purposes, a frenectomy is either performed inside the middle of the upper lip, which is called labial frenectomy, or under the tongue, called lingual frenectomy. Frenectomy is a very common dental procedure that is performed on infants, children, and adults. A similar procedure frenulotomy is where a tight frenulum may be relieved by making an incision in the tight tissue. Types There are several frenula that are associated with types of frenectomy: * Genital frenectomy can be performed to remove frenulums from genitalia * Lingual frenectomy (of the tongue) as a treatment for ankyloglossia (tongue-tie) * Labial frenectomy (of the lip) is very common with patients undergoing denture treatment to get the ...

Glans Penis
In male human anatomy, the glans penis, commonly referred to as the glans, is the bulbous structure at the distal end of the human penis that is the human male's most sensitive erogenous zone and their primary anatomical source of sexual pleasure. It is anatomically homologous to the clitoral glans. The glans penis is part of the male reproductive organs in humans and other mammals where it may appear smooth, spiny, elongated or divided. It is externally lined with mucosal tissue, which creates a smooth texture and glossy appearance. In humans, the glans is a continuation of the corpus spongiosum of the penis. At the summit appears the urinary meatus and at the base forms the corona glandis. An elastic band of tissue, known as the frenulum, runs on its ventral surface. In men who are not circumcised, it is completely or partially covered by the foreskin. In adults, the foreskin can generally be retracted over and past the glans manually or sometimes automatically dur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wing Coupling (Lepidoptera Anatomy)
Some four-winged insect orders, such as the Lepidoptera, have developed a wide variety of morphological wing coupling mechanisms in the imago which render these taxa as "functionally dipterous" (effectively two-winged) for efficient insect flight. All but the most basal forms exhibit this wing coupling. The mechanisms are of three different types - jugal, frenulo-retinacular and amplexiform. Subsec. "Wing coupling". Pp 56-60. Jugal wing coupling The more primitive groups of moth have an enlarged lobe-like area near the basal posterior margin, i.e. at the base of the forewing, called ''jugum'', that folds under the hindwing in flight. Frenulo-retinacular wing coupling Other groups of moth have a frenulum on the hindwing that hooks under a retinaculum on the forewing. The retinaculum is a hook or tuft on the underside of the forewing of some moths. Along with the frenulum, a spine at the base of the forward or costal edge of the hindwing, it forms a coupling mechanism for the f ...

Frenulum Veli
The frenulum veli, or frenulum of superior medullary velum, also known as the ''frenulum veli medullaris superioris'', ''cerebellar frenulum'', or ''frenulum cerebelli'' is a slightly raised white band passing from the inferior end of the medial longitudinal fissure, through the groove between the quadrigeminal bodies, and down to the superior medullary velum. On either side of this band the trochlear nerve emerges, and passes forward on the lateral aspect of the cerebral peduncle The cerebral peduncles are the two stalks that attach the cerebrum to the brainstem. They are structures at the front of the midbrain which arise from the ventral pons and contain the large ascending (sensory) and descending (motor) nerve trac ... to reach the base of the brain.
