terminologia histologica terminologia histologica the terminologia histologica (th) is the controlled vocabulary for use in cytology and histology. in april 2011, terminologia histologica was published online by the federative international programme on anatomical terminologies (fipat), the successor of fcat. it was intended to replace nomina histologica. the nomina histologica was introduced in 1977, with the fourth edition of nomina anatomica. it was developed by the federative international committee on anatomical terminology. outline h1.00: cytology h2.00: general histology h2.00.01.0.00001: stem cells h2.00.02.0.00001: epithelial tissue h2.00.02.0.01001: epithelial cell h2.00.02.0.02001: surface epithelium h2.00.02.0.03001: glandular epithelium h2.00.03.0.00001: connective and supportive tissues h2.00.03.0.01001: connective tissue cells h2.00.03.0.02001: extracellular matrix h2.00.03.0.03001: fibres of connective tissues h2.00.03.1.00001: connective tissue proper h2.00.03.1.01001: ligaments h2.00.03.2.00001: mucoid connective tissue; gelatinous connective tissue h2.00.03.3.00001: reticular tissue h2.00.03.4.00001: adipose tissue h2.00.03.5.00001: cartilage tissue h2.00.03.6.00001: chondroid tissue h2.00.03.7.00001: bone tissue; osseous tissue h2.00.04.0.00001: haemotolymphoid complex h2.00.04.1.00001: blood cells h2.00.04.1.01001: erythrocyte; red blood cell h2.00.04.1.02001: leucocyte; white blood cell h2.00.04.1.03001: platelet; thrombocyte h2.00.04.2.00001: plasma h2.00.04.3.00001: blood cell production h2.00.04.4.00001: postnatal sites of haematopoiesis h2.00.04.4.01001: lymphoid tissue h2.00.05.0.00001: muscle tissue h2.00.05.1.00001: smooth muscle tissue h2.00.05.2.00001: striated muscle tissue h2.00.06.0.00001: nerve tissue h2.00.06.1.00001: neuron h2.00.06.2.00001: synapse h2.00.06.2.00001: neuroglia h3.01: bones h3.02: joints h3.03: muscles h3.04: alimentary system h3.05: respiratory system h3.06: urinary system h3.07: genital system h3.08: endocrine system h3.09: cardiovascular system h3.10: lymphoid system h3.11: nervous system h3.12: the integument
