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.
