Histology Medical Terminology Presented by: Dr.Sherine Abbas  Lecturer of Forensic Medicine & Toxicology  01 Histology Definition  Histology Histo = ‫نسيج‬ ology = ‫علم‬ The microscopic study of tissues and organs through sectioning ‫ تقسيم‬, staining ‫ صبغ‬and examining ‫ فحص‬those sections under a microscope  Colors Erythro = Red Leuko = White Cyano = Blue Nigra = Black  Size Term Meaning Microcyte Small cells Macrocyte Large cells Anisocyte Unequal in size Erythrocytes Red blood cells (RBCs) Leukocytes White blood cells (WBCs) Reticulocytes Network  Stains Chromo\ Chramato = Stain ‫صبغة‬ Baso = Basic stains ‫صبغات قلوية‬ Acido = Acidic stains ‫صبغات حمضية‬ Chromatophilic Neutro = Neutral affinity ‫متعادل‬ ‫محب للصبغه‬ Philic = like ‫يحب‬ Phobic = Dislike ‫يكره‬  Term Meaning Image Laboratory instrument ‫جهاز‬ Light Microscope ‫ معملي‬that uses visible light to (L.M) detect and magnify ‫ تكبير‬very small objects. Laboratory instrument uses a beam ‫ شعاع‬of electrons to magnify a specimen. ‫عينه‬ Has higher resolution and Electron Microscope magnification power than L.M. Mainly used to observe ‫يوضح‬ the internal ‫ داخلي‬structure ‫ تركيب‬of the cell.  Term Meaning Image Layer of cells that cover (epi) all surfaces (-thelium) Epithelium of hollow ‫ مجوف‬organs and ‫النسيج الطالئي‬ glands ‫غدد‬also those cells that make up the outer surface ‫سطح‬of the body. Some epithelial cells specialized to perform secretory function.‫وظيفة افرازية‬ Glandular ‫غدة‬epithelium Gland ‫ =غدة‬Secretion ‫افرازات‬  Term Meaning Image The most common used stains in Histology Basic dye ‫صبغه‬which stain ‫ تصبغ‬the acidic cellular ‫خلوي‬structure ‫تركيب‬ Hematoxylin with purplish blue.
