capsule

 [kap´sul, kap´sūl]
1. an enclosing structure, as a soluble container enclosing a dose of medicine.
2. a cartilaginous, fatty, fibrous, or membranous structure enveloping another structure, organ, or part. adj., adj cap´sular.
 Capsule. Generalized structure of a synovial joint showing the joint or articular capsule. From Applegate, 2000.
articular capsule the saclike envelope that encloses the cavity of a synovial joint by attaching to the circumference of the articular end of each involved bone. Called also joint capsule.
adipose renal capsule the investment of fat surrounding the fibrous renal capsule, continuous at the hilus with the fat in the renal sinus.
bacterial capsule a gelatinous envelope surrounding a bacterial cell, usually polysaccharide but sometimes polypeptide in nature; it is associated with the virulence of pathogenic bacteria.
Bowman's capsule the globular dilatation forming the beginning of a renal tubule and surrounding the glomerulus. Called also glomerular capsule and malpighian capsule.
c's of the brain two layers of white matter in the substance of the brain; external capsule and internal capsule.
external capsule the layer of white fibers between the putamen and claustrum.
fibrous renal capsule the connective tissue investment of the kidney, which continues through the hilus to line the renal sinus.
Glisson's capsule a sheath of connective tissue accompanying the hepatic ducts and vessels through the hepatic portal. In hepatitis it may become stretched, which is a common cause of pain.
glomerular capsule Bowman's capsule.
capsule of heart pericardium.
internal capsule the fanlike mass of white fibers separating the lentiform nucleus laterally from the head of the caudate nucleus, the dorsal thalamus, and the tail of the caudate nucleus medially. The internal capsule carries both afferent and efferent fibers of the cerebral cortex.
joint capsule articular capsule.
capsule of lens the elastic sac enclosing the lens of the eye.
malpighian capsule Bowman's capsule.
capsule of pancreas a thin sheath of areolar tissue that invests the pancreas (but does not form a definite capsule), the septa of which extend into the gland and divide it into lobules.
renal c's the investing tissue around the kidney, divided into the fibrous renal capsule and the adipose renal capsule.
Tenon's capsule the connective tissue enveloping the posterior eyeball.

joint cap·sule

[TA]
a sac enclosing the articulating ends of the bones participating in a synovial joint, formed by an outer fibrous layer and an inner synovial membrane.
Synonym(s): capsula articularis [TA], articular capsule

joint capsule

Etymology: L, jungere, to join, capsula, little box
a fibrous saclike structure of connective tissue that envelops the end of bones in a diarthrodial joint and contains synovial fluid.

ar·tic·u·lar cap·sule

(ahr-tik'yū-lăr kap'sŭl)
A sac enclosing a joint, formed by an outer fibrous articular capsule and an inner synovial membrane.
Synonym(s): capsula articularis [TA] , joint capsule.
Basic structure of a synovial joint.

joint capsule

the fibrous tissue layer that covers a synovial joint, contributing to the 'hinge' of the joint. The capsule comprises two layers: a thick, tough, protective fibrous outer layer and an inner layer, which secretes synovial fluid, providing nutrition and lubrication to the joint.

capsule

1. an enclosing structure, as a soluble container enclosing a dose of medicine.
2. a cartilaginous, fatty, fibrous or membranous structure enveloping another structure, organ or part.

adipose renal capsule
the investment of fat surrounding the fibrous capsule of the kidney, continuous at the hilus with the fat in the renal sinus.
articular capsule
the saclike envelope that encloses the cavity of a synovial joint by attaching to the circumference of the articular end of each involved bone.
bacterial capsule
a gelatinous layer of polysaccharide surrounding a bacterial cell, usually polysaccharide but sometimes polypeptide in nature; it inhibits phagocytosis and is associated with the virulence of pathogenic bacteria.
Bowman's capsule
glomerular capsule.
brain c's
two layers of white matter in the substance of the brain. See also external capsule (below) and internal capsule (below).
external capsule
the layer of white fibers between the putamen and claustrum.
fibrous renal capsule
the connective tissue investment of the kidney, which continues through the hilus to line the renal sinus.
Glisson's capsule
a sheath of connective tissue accompanying the hepatic ducts and vessels within the liver.
glomerular capsule
the globular dilatation forming the beginning of a uriniferous tubule within the kidney, and surrounding the glomerulus. Called also Bowman's capsule and malpighian capsule.
heart capsule
pericardium.
internal capsule
the fanlike mass of white fibers separating the lentiform nucleus laterally from the head of the caudate nucleus, the dorsal thalamus, and the tail of the caudate nucleus medially.
joint capsule
articular capsule.
lens capsule
the elastic sac enclosing the lens of the eye.
malpighian capsule
see glomerular capsule (above).
Tenon's capsule
the connective tissue enveloping the posterior eyeball. Called also vagina bulbi.
