acrocephalopolysyndactyly (s) (noun), acrocephalopolysyndactylies (pl)
One of four heritable malformation syndromes recognizable at birth; acrocephalopolysyndactylia: Acrocephalopolysyndactyly is characterized by premature craniosynostosis, syndactyly, and polydactyly.
acrocephalosyndactylia (s) (noun), acrocephalosyndactylias (pl)
Craniostenosis characterized by acrocephaly and syndactyly (fusion of fingers and toes), probably occurring as an autosomal dominant trait and usually as a new mutation: Acrocephalosyndactylia 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 the bones of the head.

acrocephalosyndactyly (s) (noun), acrocephalosyndactylies (pl)
An inherited disorder causing abnormalities of the skull, the face, and the hands and feet: In acrocephalosyndactyly, there is closure too-early of some of the sutures of the skull (craniosynostosis).

This acrocephalosyndactyly 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.

adactyl (s) (noun), adactyls (pl)
A situation of being without fingers or toes.
adactylia (s) (noun), adactylias (pl)
The congenital, or at birth, absence of the digits (fingers and/or toes).
adactylism (s) (noun), adactylisms (pl)
The congenital (at birth) absence of fingers and/or toes.
adactylous (adjective), more adactylous, most adactylous
A reference to being without fingers or toes.

Also applied to crustaceous animals without claws on their feet.

adactyly (s) (noun), adactylies (pl)
The absence of digits on a hand, or both hands; or on a foot, or the feet: The new prosthesis helped Bryant to overcome the adactyly of his left hand.
anisodactylous (adjective), more anisodactylous, most anisodactylous
Characterized by unequal toes, three turned forward and one backward, as in most passerine (singing) birds.
anisodactyly (s) (noun), anisodactylies (pl)
1. Unequal length in corresponding fingers or toes; especially, referring to birds with three toes forward and one backward.

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.

Adhesion, or the fibrous adherence, between two or more fingers or toes.
arachnodactylia (s) (noun) (no pl)
Long thin fingers and toes seen in certain dysplasias: Arachnodactylia is an abnormal development or growth of tissues, organs, or cells, specifically in the hand and foot bones.
arachnodactyly (s) (noun) (no pl)
A skeletal disorder where the patient has unusually long, thin bones, especially noticeable in the fingers and toes: The extreme length and slenderness of the fingers and toes are seen in arachnodactyly or in certain dysplasias, such as the Marfan syndrome.

The 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 the Marfan syndrome, the connective tissue is defective and does not act as it should.

Because connective tissue is found throughout the body, the Marfan syndrome can affect many body systems, including the skeleton, eyes, heart and blood vessels, nervous system, skin, fingers and toes, and the lungs.

1. A herbivorous hoofed mammal with an even number of toes on each foot; such as, a cow or deer.
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.
1. An order of hoofed mammals of the subclass Eutheria (including pigs and peccaries and hippopotami and members of the suborder Ruminantia) having an even number of functional toes.
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.
