lymph (redirected from periarteriolar lymph sheath (PALS))

lymph (limf) a transparent, usually slightly yellow, often opalescent liquid found within the lymphatic vessels, and collected from tissues in all parts of the body and returned to the blood via the lymphatic system. Its cellular component consists chiefly of lymphocytes.

aplastic lymph , corpuscular lymph lymph that contains an excess of leukocytes and does not tend to become organized.

euplastic lymph , fibrinous lymph that which tends to coagulate and become organized.

inflammatory lymph  lymph produced by inflammation, as in wounds.

tissue lymph  lymph derived from body tissues and not from the blood.

lymph (lmf)

n.

A clear, watery, sometimes faintly yellowish fluid derived from body tissues that contains white blood cells and circulates throughout the lymphatic system, returning to the venous bloodstream through the thoracic duct. Lymph acts to remove bacteria and certain proteins from the tissues, transport fat from the small intestine, and supply mature lymphocytes to the blood.

Lymph

The almost colourless fluid that bathes body tissues and is found in the lymphatic vessels that drain the tissues of the fluid that filters across the blood vessel walls from blood. Lymph carries antibodies and lymphocytes (white blood cells that help fight infection) that have entered the lymph nodes from the blood.

lymph

[limf]

Etymology: L, lympha, water

a thin watery fluid originating in organs and tissues of the body that circulates through the lymphatic vessels and is filtered by the lymph nodes. Lymph enters the bloodstream at the junction of the internal jugular and subclavian veins. Lymph contains chyle, erythrocytes, and leukocytes, most of which are lymphocytes. See also chyle, lymphatic system, lymphatic vessels. lymphatic, adj.

lymph node,

n one of the many small oval structures that filter the lymph and fight infection, and in which are formed lymphocytes, monocytes, and plasma cells. See also each of the individual lymph nodes of the head and neck as they are listed.

lymph nodes, accessory,

lymph

a transparent, usually slightly yellow, often opalescent liquid found within the lymphatic vessels, and collected from tissues in most parts of the body and returned to the blood via the lymphatic system. It is about 95% water; the remainder consists of plasma proteins and other chemical substances contained in the blood plasma, but in a slightly smaller percentage than in plasma. Its cellular component consists chiefly of lymphocytes.

lymph duct

large vessels carrying lymph from smaller collecting vessels. Include thoracic duct, right lymphatic duct.

lymph heart

a muscular dilatation in a lymph vessel, capable of contraction and moving lymph along the vessel. Seen in embryos and lower vertebrates.

lymph node

any of the accumulations of lymphoid tissue organized as definite lymphoid organs along the course of lymphatic vessels, consisting of an outer cortical and an inner medullary part; they are the main source of lymphocytes of the peripheral blood and, as part of the reticuloendothelial system, serve as a defense mechanism by removing noxious agents, e.g. bacteria and toxins, and play a critical role in antibody formation. Sometimes called, incorrectly, lymph glands.

lymph node abscess

hard, usually cold swellings containing pus; secondary to primary lesion in node's drainage area; a feature of some chronic infections, e.g. tuberculosis, caseous lymphadenitis of sheep; specific nodes may cause specific syndromes, e.g. retropharyngeal nodes.

lymph node hyperplasia

increase in size due to increase in number of normal cells but with preservation of natal architecture.

lymph node hypoplasia

occurs in cattle and causes antenatal edema of the fetus, leading to dystocia in many cases. The calves are not viable.

lymph nodule

germinal centers in lymph nodes which produce lymphocytes. Called also lymphatic or lymphoid nodule.

periarteriolar lymph sheath (PALS)

the white pulp, heavily populated with T lymphocytes, that surrounds arteries in the spleen.

lymph tissue

see lymphoid tissue.

Q. tender protuding lymph node lump rt. arm pit aprox. 1/2" dia. any concerns or recommend treatment necessary?

A. lymph nodes can flare up any time you get infected in the armpit and all the area that it drains. i had it several times and it went away in the same manner that it came. i think that sometimes it caused because of a blockade done by deodorant. so i try to use this Chinese salt stone that doesn't contain aluminum.
