adipose renal capsule the investment of fat surrounding the fibrous capsule of the kidney, continuous at the hilum with the fat in the renal sinus.
articular capsule joint capsule; the saclike envelope enclosing the cavity of a synovial joint.
auditory capsule the cartilaginous capsule of the embryo that develops into the bony labyrinth of the inner ear.
bacterial capsule an envelope of gel surrounding a bacterial cell, usually polysaccharide but sometimes polypeptide in nature; it is associated with the virulence of pathogenic bacteria.
cartilage capsule a basophilic zone of cartilage matrix bordering on a lacuna and its enclosed cartilage cells.
external capsule the layer of white fibers between the putamen and claustrum.
fibrous renal capsule the connective tissue investment of the kidney, continuous through the hilum to line the renal sinus.
Glisson's capsule the connective tissue sheath accompanying the hepatic ducts and vessels through the hepatic portal.
glomerular capsule , capsule of glomerulus the globular dilatation forming the beginning of a uriniferous tubule within the kidney and surrounding the glomerulus.
internal capsule a 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 c.
capsule of lens the elastic envelope covering the lens of the eye.
optic capsule the embryonic structure from which the sclera develops.
otic capsule the skeletal element enclosing the inner ear mechanism. In the human embryo, it develops as cartilage at various ossification centers and becomes completely bony and unified at about the 23rd week of fetal life.
renal capsules 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.
| internal capsule n. A layer of white matter separating the caudate nucleus and thalamus from the lentiform nucleus and serving as the major route by which the cerebral cortex is connected with the brainstem and the spinal cord. |

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.
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.

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.
