| seminal capsule | <anatomy> The paired glands at the base of the bladder that produce seminal fluid and fructose. (09 Oct 1997) |
| nasal capsule | The cartilage around the developing nasal cavity of the embryo. (05 Mar 2000) |
| subrenal capsule assay | In vivo method of screening investigative anticancer drugs and biologic response modifiers for individual cancer patients. Fresh tumour tissue is implanted under the kidney capsule of immunocompetent mice or rats; gross and histological assessments follow several days after tumour treatment in situ. (12 Dec 1998) |
| suprarenal capsule | See adrenal gland. (12 Dec 1998) |
| India ink capsule stain | <technique> A negative stain for crystal bacteria in which cells appear purple (Gram's crystal violet) and the capsules appear clear against a dark background. (05 Mar 2000) |
| optic capsule | The concentrated zone of mesenchyme around the developing optic cup; the primordium of the sclera of the eye. (05 Mar 2000) |
| otic capsule | The cartilage capsule surrounding the inner ear mechanism; in elasmobranchs, it remains cartilaginous in the adult; in the embryos of higher vertebrates, it is cartilaginous at first but later becomes bony (at approximately 23 weeks in humans). (05 Mar 2000) |
| Tenon's capsule | A condensation of connective tissue on the outer aspect of the sclera from which it is separated by a narrow cleftlike episcleral space; the sheath is attached to the sclera near the sclerocorneal junction and blends with the fascia of the extraocular muscles. Synonym: vagina bulbi, capsula bulbi, eye capsule, fascia bulbi, sheath of eyeball, Tenon's capsule, vagina oculi. (05 Mar 2000) |
| joint capsule | The sac-like envelope which encloses the cavity of a synovial joint by attaching to the circumference of the articular end of each involved bone. It consists of two layers. The fibrous membrane of the articular capsule (membrana fibrosa capsulae articularis) is the outer layer and is composed of dense white fibrous tissue. The synovial membrane (membrana synovialis capsulae articularis) is the inner layer composed of loose connective tissue and possessing a smooth surface lining the joint cavity. (12 Dec 1998) |
| external capsule | A thin lamina of white substance separating the claustrum from the putamen. It joins the internal capsule at either extremity of the putamen, forming a capsule of white matter external to the lenticular nucleus. Synonym: capsula externa, periclaustral lamina. (05 Mar 2000) |
| extreme capsule | The layer of white matter separating the claustrum from the cortex of the insula, probably representing largely corticopetal and corticofugal fibres of the insular cortex. Synonym: capsula extrema. (05 Mar 2000) |
| eye capsule | A condensation of connective tissue on the outer aspect of the sclera from which it is separated by a narrow cleftlike episcleral space; the sheath is attached to the sclera near the sclerocorneal junction and blends with the fascia of the extraocular muscles. Synonym: vagina bulbi, capsula bulbi, eye capsule, fascia bulbi, sheath of eyeball, Tenon's capsule, vagina oculi. (05 Mar 2000) |
| fatty renal capsule | The perirenal fat. Synonym: capsula adiposa renis, adipose capsule. (05 Mar 2000) |
| fibrous articular capsule | The outer fibrous part of the capsule of a synovial joint, which may in places be thickened to form capsular ligaments. Synonym: membrana fibrosa, stratum fibrosum, fibrous membrane. (05 Mar 2000) |
