Accessory nerve
|
|
Accessory nerveThe eleventh cranial nerve, which emerges from the skull and receives an additional (accessory) root from the upper part of the spinal cord. It 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. The accessory nerve is so-called because, although it arises in the brain, it receives an additional (accessory) root from the upper part of the spinal cord. 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.
RELATED TERMS--------------------------------------
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
Nerve
Tissue that conveys sensation, temperature, position information to the brain.
Skull
The bony framework of the head.
Root
Tooth structure that connects the tooth to the jaw.
Cord
1. In anatomy, a long ropelike structure. 2. Short for the spinal cord or the umbilical cord.
Muscle
Tissue made up of bundles of long, slender cells that contract when stimulated.
Scapula
The shoulder blade.
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.
Brain
"That part of the central nervous system that is located within the cranium (skull). The brain functions as the primary receiver, organizer and distributor of information for the body. It has two (right and left) halves called ""hemispheres."" "
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.

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."
