Accessory neuropathy
|
|
Accessory neuropathyDisease of the accessory nerve which is the eleventh cranial nerve. The accessory nerve supplies the sternocleidomastoid and trapezius muscles. The sternocleidomastoid muscle is in the front of the neck and turns the head. The trapezius muscle moves the scapula (the wingbone), turns the face to the opposite side, and helps pull the head back. Damage to the accessory nerve can be confined to the accessory nerve or it may also involve the ninth and tenth cranial nerves which exit through the same opening (foramen) from the skull . Accessory neuropathy can sometimes occur and recur for unknown reasons. Most patients recover. Paralysis of the accessory nerve prevents rotation of the head away from that side and causes drooping of the shoulder.
RELATED TERMS--------------------------------------
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
Accessory
Additional, extra, supplementary, subsidiary to the main thing. An accessory digestive organ is an organ that helps with digestion but is not part of the digestive tract. The accessory nerve is so-called because it receives an additional (accessory) root from the upper part of the spinal cord. An accessory placenta is an extra placenta separate from the main placenta.
Nerve
Tissue that conveys sensation, temperature, position information to the brain.
Cranial
The anatomical term for towards the head; also the general term for of the head. i.e. the lungs are cranial to the pelvis. See Caudal/Inferior/Superior
Muscle
Tissue made up of bundles of long, slender cells that contract when stimulated.
Scapula
The shoulder blade.
Skull
The bony framework of the head.
Neuropathy
A disease of the nervous system. The three major forms in people with diabetes are peripheral neuropathy, autonomic neuropathy, and mononeuropathy. The most common form is peripheral neuropathy, which affects mainly the legs and feet.
Paralysis
Inability to move parts of the body.
Shoulder
The ball-and-socket joint connecting the arm with the body.

Accelerated phase of leukemia
Refers to chronic myelogenous leukemia (CML) that is progressing. The number of immature, abnormal white blood cells in the bone marrow and blood is higher than in the chronic phase but not as high as in the blast phase.
Acceptable daily intake
Estimate of the amount of a substance in food or drinking water, expressed on a body mass basis (usually mg/kg body weight), which can be ingested daily over a lifetime by humans without appreciable health risk. For calculation of the daily intake per person, a standard body mass of 60 kg is used. The acceptable daily intake is normally used for food additives (tolerable daily intake is used for contaminants). Abbreviated ADI.
Access
1. In general, a means of approaching something. 2. In health care, the opportunity or right to receive health care. 3. In dialysis, the point on the body where a needle or catheter is inserted to gain entry to the bloodstream.
Accessibility of services
The ability to get medical care and services when needed.
Accessible
Refers to tumors that can be approached by a surgical procedure; tumors that are not deep in the brain or beneath vital structures. Inaccessible tumors cannot be approached by standard surgical techniques.
Accessory
Additional, extra, supplementary, subsidiary to the main thing. An accessory digestive organ is an organ that helps with digestion but is not part of the digestive tract. The accessory nerve is so-called because it receives an additional (accessory) root from the upper part of the spinal cord. An accessory placenta is an extra placenta separate from the main placenta.
Accessory cell
Cell required for, but not actually mediating, a specific immune response. Often used to describe antigen-presenting cells (APC; see below).
Accessory digestive organ
An organ that helps with digestion but is not part of the digestive tract. The accessory digestive organs are the tongue, salivary glands, pancreas, liver, and gallbladder.
Accessory digestive organs
Organs that help with digestion but are not part of the digestive tract. These organs are the tongue, glands in the mouth that make saliva, pancreas, liver, and gallbladder.
Accessory dwelling unit
(ADU) A separate housing arrangement within a single-family home. The ADU is defined by Medicare as a complete living unit and includes a private kitchen and bath.

Damage to the accessory nerve can be isolated (confined to the accessory nerve) or it may also involve the ninth and tenth cranial nerves which exit through the same opening (foramen) from the skull . Accessory neuropathy (nerve disease) can sometimes occur and recur for unknown reasons. Most patients recover. Paralysis of the accessory nerve prevents rotation of the head away from that side and causes drooping of the shoulder.
Accessory oculomotor nucleus
Receives input from the pretectal area, innervates the ciliary ganglion. Mediates pupillary light reflexes.
Accessory optic system (AOS)
Region of the vertebrate midbrain to which some optic nerve fibers project. Cells respond to large slowly moving textured patterns and are selective for both direction and speed of motion suggesting they are involved in the computation of global motion. Possibly used for the detection of retinal slip and used in image stabilization. Consists of two sets of retina ganglion cell fibers and three target nuclei in the anterior portion of the midbrain, the dorsal, medial and lateral nuclei.
Accessory placenta
"An extra placenta separate from the main placenta. Also called a succenturiate or supernumerary placenta. The placenta is the organ joining the mother and fetus, the organ that permits the provision of oxygen and nutrients to the fetus and the release of carbon dioxide and waste products from the fetus to the mother. The word ""placenta"" means a flat cake. The main placenta is disk-shaped and at full term measures about 7 inches (18 cm) in diameter and a bit less than 2 inches (4 cm) thick. The upper surface of the placenta is smooth while the under surface is rough. The placenta and the fetal membranes are the afterbirth."

Acclimatization to altitude
The main cause of altitude sickness is going too high too fast. Given time, the body can adapt to the decrease in oxygen concentration at a specific altitude, process known as acclimatization.
Accoucheur
French for a male obstetrician, a physician skilled in the art and science of managing pregnancy, labor and the puerperium (the time after delivery).
Accoucheuse
"French for a woman who is an obstetrician (a physician skilled in the art and science of managing pregnancy, labor and the time after delivery) or a midwife (today a non-physician trained to assist a woman during childbirth). The ending ""-euse"" is feminine and indicates that the accoucheuse is a woman."
ACE (angiotensin converting enzyme)
The angiotensins are peptides (substances smaller than proteins) that act as vasoconstricting agents (causing blood vessels to narrow). Narrowing the diameter of the blood vessels sends up the blood pressure. ACE converts angiotensin to its activated form (called angiotensin II) enabling it to function. The ACE inhibitors are drugs that inhibit the formation of angiotensin II and are used for blood pressure control and congestive heart failure. The ACE inhibitors include benazepril (brand name: Lotensin), captopril (brand name: Capoten), lisinopril (brand names: Zestril and Prinivil), quinapril (brand name: Accupril), and ramipril (brand name: Altace).
