Anatomy
(1) A fibromembranous covering of an organ (e.g., the kidney, liver).
(2) The fibrous covering of a joint.

Chinese medicine
Jaio niang—A gelatin sheath filled with finely ground powder, which allows the optimal delivery of pungent or bitter herbs.

Microbiology
Microcapsule—A thick, gel-like material composed of highly hydrophilic acidic polysaccharide, which covers the wall of gram-positive or gram-negative bacteria and imparts a smooth appearance to colonies in culture; the capsule is linked to bacterial pathogenicity, as it inhibits phagocytosis.
 
Pathology
A thick fibrous material that ensheathes benign tumours, cysts or parasites that have been “walled off” as a host defence.
 
Pharmacology
A solid dosage form of a drug, in which the drug is enclosed in a hard or soft soluble container or shell of an appropriate gelatin.
