ATL
The disease variously called adult T-cell leukemia, adult T-cell leukemia/lymphoma and adult T-cell lymphoma. For more information, see: Adult T-cell leukemia.
Atlantoaxial
Pertaining to the first and second cervical vertebrae which meet at a joint called the atlantoaxial joint. The uppermost cervical vertebra (the atlas) rotates about the odontoid process of the second cervical vertebra (the axis). The joint between the axis and atlas is a pivot type of joint that allows the head turn.
Atlas
The atlas is the first cervical (neck) vertebra (symbol: C1). It supports the head. The atlas bone is named for the Greek god Atlas who was condemned to support the earth and its heavens on his shoulders. (Because the god Atlas often adorned maps, a compilation of maps came to be known as an atlas).
Atlas and axis joint
"The joint between the atlas and axis bones. The atlas is the first cervical (neck) vertebra which is just under the head; it is named for Atlas, the Greek god who supported the world on his shoulders. The axis is the second cervical vertebra; it has what is called the odontoid process about which the atlas rotates. The joint between the atlas and axis is a pivot type of joint. It allows the head turn from side to side. It is also called the atloaxoid joint.The ligaments that serve to support and strengthen this joint are called the capsular; anterior and posterior atlantoaxial; and transverse ligaments."
Atloaxoid joint
"The joint between the atlas and axis bones. The atlas is the first cervical (neck) vertebra which is just under the head; it is named for Atlas, the Greek god who supported the world on his shoulders. The axis is the second cervical vertebra; it has what is called the odontoid process about which the atlas rotates."
ATN
Atom
The smallest part of any material that cannot be broken up by chemical means. Each atom has a center (the nucleus) which contains protons and neutrons. Electrons orbit around the nucleus. The atom is primarily empty space.
Atonia, REM sleep
A frightening form of paralysis that occurs when a person suddenly finds himself or herself unable to move for a few minutes, most often upon falling asleep or waking up. Commonly called sleep paralysis, the condition is due to an ill-timed disconnection between the brain and the body.
Atonic
Without normal muscle tone or strength. An atonic seizure is one in which the person suddenly loses muscle tone and strength and cannot sit or stand upright and, unless supported, falls down.
Atonic seizure
A seizure in which the person suddenly loses muscle tone and strength and, unless supported, falls down. Also called drop attack or drop seizure. Atonic means a lack of muscle tone and strength.
Atopic
Prone to allergies or characterized by allergy.
