| trophic | <gastroenterology> Of or pertaining to nutrition. Origin: Gr. Trophikos (18 Nov 1997) |
| trophic changes | Abnormalities of the skin, hair, nails, subcutaneous tissues and bone, caused by peripheral nerve lesions. Synonym: neuritic atrophy, neurogenic atrophy, neurotrophic atrophy, trophic changes. (05 Mar 2000) |
| trophic gangrene | Ulcer resulting from cutaneous sensory denervation. See: perforating ulcer of foot. Synonym: trophic gangrene. (05 Mar 2000) |
| trophic level | <biology> Stage in a food chain or web leading from primary producers (lowest trophic level) through herbivores to primary and secondary carnivores (consumers- highest level). (09 Oct 1997) |
| trophic nucleus | The larger nucleus (or sometimes nuclei) in ciliate protozoans. Derived from the micronucleus by a process of DNA polytenisation. The DNA in the macronucleus is actively transcribed. The macronucleus degenerates before conjugation. (18 Nov 1997) |

| trophoblast | <embryology> Extra embryonic layer of epithelium that forms around the mammalian blastocyst and attaches the embryo to the uterus wall. Forms the outer layer of the chorion and together with maternal tissue will form the placenta. (18 Nov 1997) |
| trophoblast protein 1 | <protein> Protein secreted by trophoblasts, which prolongs the lifetime of the corpus luteum, thus signalling pregnancy. Structurally related to interferons. (18 Nov 1997) |
| trophoblastic | Relating to the trophoblast. (05 Mar 2000) |
| trophoblastic lacuna | One of the spaces in the early syncytiotrophoblastic layer of the chorion before the formation of villi; in human embryos maternal blood enters these spaces by the 10th day; with the differentiation of the chorionic villi they become intervillous spaces, sometimes called intervillous lacunae. (05 Mar 2000) |
| trophoblast |
As the cells of the early embryo specialize, they soon differentiate into: (1) central ones that will form the embryo or fetus itself; and (2) peripheral ones (the trophoblast) that will be responsible for invading the mother

| tropical spastic paraparesis |
A rare disorder characterized by slowly progressive weakness (paraparesis), stiffness (rigidity), and spasticity of the leg muscles due to infection with the human T-cell lymphotropic virus-1 (HTLV-1). Modes of transmission include sexual contact, mother-to-child transmission (eg, via breastfeeding), and blood transfusion.
