Pheromones. Synomones . Allelochemicals . Allomones . Ectohormones . Kairomones . Semiochemicals . Chemical substances, excreted by an organism into the environment, that elicit behavioral or physiological responses from other organisms of the same species. Perception of these chemical signals may be olfactory or by contact. . 1.00
Synovial Fluid. Fluid, Synovial . Fluids, Synovial . Synovial Fluids . Synovia . The clear, viscous fluid secreted by the SYNOVIAL MEMBRANE. It contains mucin, albumin, fat, and mineral salts and serves to lubricate joints. . 0.53
gamma-Synuclein. Persyn . Synoretin . gamma Synuclein . A homolog of ALPHA-SYNUCLEIN that plays a role in neurofilament network integrity. It is overexpressed in a variety of human NEOPLASMS and may be involved in modulating AXON architecture during EMBRYONIC DEVELOPMENT and in the adult. Gamma-Synuclein may also activate SIGNAL TRANSDUCTION PATHWAYS associated with ETS-DOMAIN PROTEIN ELK-1. . 0.51
Synostosis. Synostoses . A union between adjacent bones or parts of a single bone formed by osseous material, such as ossified connecting cartilage or fibrous tissue. (Dorland, 27th ed) . 0.49
Synovial Membrane. Membrana Synovialis Capsulae Articularis . Membrane, Synovial . Membranes, Synovial . Synovial Membranes . Synovium . The inner membrane of a joint capsule surrounding a freely movable joint. It is loosely attached to the external fibrous capsule and secretes SYNOVIAL FLUID. . 0.49
Sarcoma, Synovial. Sarcomas, Synovial . Synovial Sarcoma . Synovial Sarcomas . Synoviomas . Synovioma . A malignant neoplasm arising from tenosynovial tissue of the joints and in synovial cells of tendons and bursae. The legs are the most common site, but the tumor can occur in the abdominal wall and other trunk muscles. There are two recognized types: the monophasic (characterized by sheaths of monotonous spindle cells) and the biphasic (characterized by slit-like spaces or clefts within the tumor, lined by cuboidal or tall columnar epithelial cells). These sarcomas occur most commonly in the second and fourth decades of life. (From Dorland, 27th ed; DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1363) . 0.48
