(Greek: finger, toe)
Craniostenosis refers to the premature closure of cranial sutures resulting in malformation of the skull. The cranial sutures refer to a type of fibrous joint between bones of the head.
In acrocephalosyndactyly, there is closure too-early of some of the sutures of the skull (craniosynostosis).
This results in an abnormally shaped head, which is unusually tall and peaked, and an abnormally shaped face with shallow eye sockets and underdevelopment of the midface. There is also a fusion of fingers and toes (syndactyly) and the broad ends of the thumbs and big toes.
Also applied to crustaceous animals without claws on their feet.
This is common with songbirds and other perching birds, as well as hunting birds; such as, eagles, hawks, and falcons.
2. Possessing corresponding digits of unequal length on either side of the body.
3. Having unequal toes.
4. A group of herbivorous mammals characterized by having the hoofs in a single series around the foot; such as, the elephant, rhinoceros, etc.
2. Extreme length and slenderness of the fingers or toes.
3. The long thin fingers and toes seen in certain dysplasias; such as, the Marfan syndrome.
Marfan syndrome is a heritable condition that affects the connective tissue.
The primary purpose of connective tissue is to hold the body together and to provide a framework for growth and development. In Marfan syndrome, the connective tissue is defective and does not act as it should.
Because connective tissue is found throughout the body, Marfan syndrome can affect many body systems, including the skeleton, eyes, heart and blood vessels, nervous system, skin, fingers and toes, and the lungs.
2. Any of various hoofed mammals of the order Artiodactyla, which includes cattle, deer, camels, hippopotamuses, sheep, and goats, that have an even number of toes; usually two or sometimes four, on each foot.
2. The order of mammals that contains the even-toyed ungulates, in which the weight of the body is supported on the third and fourth digits only.
These large herbivorous mammals include sheep, goats, deer, domestic cattle, antelopes, pigs, camels, and giraffes.
The cud-chewing cloven-hoofed camels and ruminants have three or four chambers in the stomach, food being regurgitated from the first and chewed while the animal is resting before being swallowed again for complete digestion.
