Interdigital Webbing Human, This condition can be present at birth (congenital) or can develop later in life due to certain medical conditions or injuries. Here, the delta (triangular) shape of the foot is clearly visible. The Specific Name and Anatomy The skin between your fingers is commonly referred to as the “webbing” or “web space. Bone Interdigital webbing is commonly found in aquatic animals such as ducks and frogs, providing them with increased surface area for effective swimming. Jan 19, 2026 · Interdigital webbing refers to the presence of skin membranes. ” Anatomically, the precise medical term is the interdigital web or interdigital fold (Plica interdigitalis). Several distinct conditions can give rise to webbed feet, including interdigital webbing and syndactyly. In some species, the degree of interdigital webbing can vary significantly based on their habitat, with more extensive webbing seen in fully aquatic organisms compared to semi-aquatic ones. This fascinating process has often been considered as an altruistic cell suicide that is evolutionarily-regulated in species with different degrees of digit webbing. Interdigital webbing refers to the presence of skin membranes. In a short time interval the interdigital mesoderm undergoes massive degeneration to determine the formation of free digits. A failure of this process causes persistence of interdigital webbing and consequently cutaneous syndactyly. Membranes of skin between fingers and toes of animals Checking your browser before accessing pubmed. Interdigital webbing refers to the skin and connective tissue that connects the toes in the paw, which is examined for conditions such as discoloration and abrasions. The skin in the first interdigital space is innervated by the deep peroneal nerve. They found that removal of the interdigital membrane by cell death depends on the production of reactive oxygen species, which only occurs in embryos exposed to a high oxygen concentration during development. Normally, in mammals, webbing is present but resorbed later in development, but in various mammal species, it occasionally persists in adulthood. This triangular-shaped area is situated between adjacent fingers, extending from the base toward the knuckles. There are a total of four interdigital spaces, numbered from the inside to the outside. This shape allows for the formation of leading edge vortices and lift-based propulsion during swimming. a. web spaces of the foot). The skin in the first interdigital space is innervated by the deep peroneal nerve. nih. This modification significantly increases the surface area of the feet. The spaces between the toes are known as the interdigital spaces of foot (a. This causes a white and ‘soggy’ appearance to the skin between the toes that alters the normal microbiological flora that increases the risk for a . The webbing can consist of membrane, skin, or other connective tissue and varies widely in different taxa. gov Webbing of the digits, or syndactyly, is not caused by the fingers sticking together in the womb; rather, it is caused by failure, during the sixth to eighth weeks of intrauterine life, of the usual longitudinal interdigital necrosis that normally separates the fingers. Interdigital maceration of the skin occurs when the normal balance of the water content is disrupted because of either excessive production of moisture (ie sweating) or if the evaporation of that moisture is impaired (ie between the toes). This “webbing” is the most common abnormality of the newborn hand. The elaborate anatomy of hands and feet is shaped by coordinated formation of digits and regression of the interdigital mesenchyme (IM). In humans, it can be found in those suffering from LEOPARD syndrome and from Aarskog–Scott May 29, 2013 · This paper presents evidence that lysosomal-mediated cell death and extracellular matrix degradation are important events in addition to cell death by apoptosis. A webbed foot has connecting tissue between the toes of the foot. k. Interdigital webbing is not to be confused with syndactyly, which is a fusing of digits and occurs rarely in humans. [1] The webbed foot is a specialized limb with interdigital membranes (webbings) that aids in aquatic locomotion, present in a variety of tetrapod vertebrates. In humans, it can be found in those suffering from LEOPARD syndrome and from Aarskog–Scott syndrome. The remaining interdigital spaces of foot receive their cutaneous innervation from the superficial peroneal nerve on the Webbed feet of a mute swan. Interdigital webbing is not to be confused with syndactyly, which is a fusing of digits and occurs rarely in humans. ncbi. This adaptation is primarily found in Jun 14, 2019 · The webbing between the fingers of some animals – the interdigital membranes – is formed in different ways across species. Interdigital webbing is a condition in which the skin between the digits (fingers or toes) extends further than normal, creating a webbed appearance. nlm. The author proposes the use of the term interdigital cell death– extracellular matrix degradation instead of interdigital apoptosis. Syndactyly specifically affecting feet occurs in birds (such as ducks), amphibians (such as frogs), and mammals (such as the kangaroo). ybnhpnbgt jaujdl f7frh qrxxq9jk kvhm hd24z jebanhp dcp bpffe x7dz \
