| joint branches | Branches distributed to joints. Almost any vessel related to a joint will supply articular rami. Most joints receive articular branches from the intramuscular branches of the motor nerves innervating the muscles crossing the joint (see Hilton's law). at this printing, Nomina Anatomica, however, specifically recognises only the articular branches of the descending genicular artery, ramus articulares arteriae descendentis genicularis; supplying the knee joint. Synonym: rami articulares, joint branches. (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) |

| joint-fir | <botany> A genus (Ephedra) of leafless shrubs, with the stems conspicuously jointed; called also shrubby horsetail. There are about thirty species, of which two or three are found from Texas to California. Source: Websters Dictionary (01 Mar 1998) |
| joint hypermobility syndrome | <syndrome> A common benign childhood condition involving hypermobile joints (that can move beyond the normal range of motion). Symptoms include pains in knees, fingers, hips, and elbows. The affected joints may sprain or dislocate. Scoliosis (curvature of the spine) is more frequent. Usually improves with adulthood. Also called the hypermobility syndrome. (12 Dec 1998) |
| joint instability | Lack of stability of a joint or joint prosthesis. Factors involved are intra-articular disease and integrity of extra-articular structures such as joint capsule, ligaments, and muscles. (12 Dec 1998) |
| joint loose bodies | Fibrous, bony, cartilaginous and osteocartilaginous fragments in a synovial joint. Major causes are osteochondritis dissecans, synovial chondromatosis, osteophytes, fractured articular surfaces and damaged menisci. (12 Dec 1998) |
| joint mice | <radiology> Ossicles within joint space, seen in synovial osteochondromatosis (12 Dec 1998) |
| joint of head of rib | The synovial joint between a rib and bodies of two adjacent vertebrae; the joint cavity is divided by an intra-articular ligament which attaches to the intervertebral disk; the first, tenth, eleventh, and twelfth ribs articulate with only one vertebra. Synonym: articulatio capitis costae, capitular joint. (05 Mar 2000) |
