Avulsion

AvulsionTearing away. A nerve can be avulsed by an injury, as can part of a bone.
RELATED TERMS--------------------------------------
Nerve
Tissue that conveys sensation, temperature, position information to the brain.
Injury
Injury is damage or harm caused to the structure or function of the body caused by an outside agent or force, which may be physical or chemical.
Bone
Bone refers either to a hardened connective tissue or to one of the individual structures, or organs, into which it is formed, found in many animals. Bones support body structures, protect internal organs, and (in conjunction with muscles) facilitate movement; are also involved with cell formation, calcium metabolism, and mineral storage. The bones of an animal are, collectively, known as the skeleton.
SIMILAR TERMS--------------------------------------
Avulse
To separate or tear away a body part, as from an accident or surgery. While playing football, he avulsed a spinous process.

AVM
An AVM (arteriovenous malformation) is a congenital disorder (one present at birth) of blood vessels in the brain, brainstem, or spinal cord that is characterized by a complex, tangled web of abnormal arteries and veins connected by one or more fistulas (abnormal communications).The AVM has no capillary bed of its own and the fistulas in the AVM permit high-speed, high-flow shunting of blood from the arterial to the venous side of the circulation. This shunting causes low blood pressure (hypotension) in the arterial vessels feeding the AVM and neighboring areas of the brain that they normally supply with blood.AVMs typically cause problems before the age of 40. The most common symptoms of AVM include hemorrhaging (bleeding), seizures, headaches, and neurological problems such as paralysis or loss of speech, memory, or vision. The frequency of hemorrhage in various series ranges from 30-82%. AVM rupture accounts for 2% of all strokes.

Axelrod, Julius
(1912- ) American pharmacologist and neuroscientist who shared the 1970 Nobel Prize in Physiology or Medicine for his discovery of the actions of neurotransmitters in regulating the metabolism of the nervous system.
Axial tomography, computerized
Pictures of structures within the body created by a computer that takes the data from multiple X-ray images and turns them in pictures. The CAT (computerized axial tomography) scan can reveal some soft-tissue and other structures that cannot be seen in conventional X-rays. Using the same dosage of radiation as that of an ordinary X-ray machine, an entire slice of the body can be made visible with about 100 times more clarity with the CAT scan.
Axillary
"Pertaining to the cavity beneath the junction of the arm and the body, better known as the armpit. The word ""axilla"" was borrowed directly from the Latin. To the Romans, as to us, the axilla was just the armpit."
