histology=الهستولوجيا

ONLINE ETYMOLOGY DICTIONARY

histology (n.)
"study of organic tissues," 1847, from histo- + -ology.
histo-
medical word-forming element, from Gk. histos "warp, web," lit. "anything set upright," from histasthai "to stand," from PIE *sta- "to stand" (see stet). Taken by 19c. medical writers as the best Greek root from which to form terminology for "tissue."
-ology
word-forming element indicating "branch of knowledge, science," now the usual form of -logy. Originally used c.1800 in nonce formations (commonsensology, etc.), it gained legitimacy by influence of the proper formation in geology, mythology, etc., where the -o- is a stem vowel in the previous element.
WIKIPEDIA


Histology (compound of the Greek words: ἱστός "tissue", and -λογία -logia) is the study of the microscopic anatomy of cells and tissues of plants and animals. It is commonly performed by examining cells and tissues by sectioning and staining, followed by examination under a light microscope or electron microscope
