Erb palsy
|
|
Erb palsyA form of brachial plexus palsy in which there is paralysis of the muscles of the upper arm and shoulder girdle due to an injury to the roots of fifth and sixth cervical roots or the upper part of the brachial plexus, a network of spinal nerves that originates in the back of the neck, extends through the axilla (armpit), and gives rise to nerves to the upper limb. The brachial plexus is formed by the union of portions of the fifth through eighth cervical nerves and the first thoracic nerve, all of which come from the spinal cord. In Erb palsy, the arm is internally rotated and hangs limply at the side.
RELATED TERMS--------------------------------------
Plexus
A network of nerves or veins.
Palsy
Paralysis of a muscle or group of muscles
Paralysis
Inability to move parts of the body.
Shoulder
The ball-and-socket joint connecting the arm with the body.
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.
Cervical
Having to do with the neck (cervical spine) or the cervix of the uterus.
Axilla
The armpit
Thoracic
Pertaining to or affecting the chest.
Nerve
Tissue that conveys sensation, temperature, position information to the brain.
Cord
1. In anatomy, a long ropelike structure. 2. Short for the spinal cord or the umbilical cord.
SIMILAR TERMS--------------------------------------
PREVIOUS AND NEXT TERMS--------------------------------------
Epstein-Barr virus
A virus, abbreviated EBV, best known as the cause of infectious mononucleosis ("mono"). Infection with EBV is characterized by fatigue and general malaise. Infection with EBV is fairly common and is usually a transient and minor thing. However, in some individuals EBV can trigger chronic illness, including immune and lymphoproliferative syndromes. It is a particular danger to people with compromised immune systems, such as from AIDS. EBV was at one time believed to be the cause of the chronic fatigue syndrome, but chronic infection with this virus actually produces a separate (if similar) disorder.
EPT
Estrogen/progestin therapy.
Equinophobia
An abnormal and persistent fear of horses. Sufferers of equinophobia experience undue anxiety even when a horse is known to be gentle and well trained. They usually avoid horses entirely rather than risk being kicked, bitten or thrown. They may also fear other hoofed animals such as ponies, donkeys and mules.
Equol
A substance produced in the intestine as a metabolite of soybeans and soy foods. Equol is a non-steroidal estrogen that acts as an anti-androgen by blocking the hormone dihydrotestosterone. Some people are able to produce equol while others cannot. Equol is chemically unique among the isoflavones (a family of phytoestrogens, plant estrogens). It is the major metabolite of the phytoestrogen daidzein, an isoflavone abundant in soybeans and soy foods.
ER
1. Emergency room. 2. Endoplasmic reticulum. 3. Estrogen receptor. 4. Extended release.
Erb palsy
ERCP
Endoscopic retrograde cholangiopancreatography.
Erection, penile
When the penis fills with blood and is rigid. The penis contains two chambers, called the corpora cavernosa, which run the length of the organ, are filled with spongy tissue, and surrounded by a membrane, called the tunica albuginea. The spongy tissue contains smooth muscles, fibrous tissues, spaces, veins, and arteries. The urethra, which is the channel for urine and ejaculate, runs along the underside of the corpora cavernosa. Erection begins with sensory and mental stimulation. Impulses from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the open spaces. The blood creates pressure in the corpora cavernosa, making the penis expand. The tunica albuginea helps to trap the blood in the corpora cavernosa, thereby sustaining erection. Erection is reversed when muscles in the penis contract, stopping the inflow of blood and opening outflow channels.
ERG
Electroretinography.
Ergophobia
An abnormal and persistent fear of work. Sufferers of ergophobia experience undue anxiety about the workplace environment even though they realize their fear is irrational. Their fear may actually be a combination of fears, such fear of failing at assigned tasks, fear of speaking before groups at work, or fear of socializing with co-workers.
Ergot
Ergot could be called a "cereal killer" for it comes from cereals such as rye and wheat and is quite capable of killing someone. A fungus (Claviceps purpurea) that contaminates rye and wheat produces substances (alkaloids) termed ergotamines. Ergotamines constrict blood vessels and cause the muscle of the uterus to contract. They have been much used and been very useful for the treatment of migraine. They have also been used and misused as abortifacients (agents of abortion).
