histo-, hist-, histi- +

(Greek: tissue [web]; beam or warp of a loom; hence, that which is woven; a web or tissue; used in the sense of pertaining to [body] tissue)

histology
1. The study of tissues and cells at the microscopic level.
2. An integral subspeciality of anatomy wherein the tissue and cells of an organism's structures are treated with special chemicals and studied with the light microscope.
histolysate
Any substance formed by the dissolution of tissue.
histolysis
Disintegration of the tissues.
histolytic
1. A reference to the disintegration of the bodily tissues.
2. Characterized by or inducing the dissolution of tissue.
histoma
1. A tumor composed of tissue.
2. A benign neoplasm in which the cytologic and histologic elements are closely similar to those of normal tissue from which the neoplastic cells are derived.
3. A new and abnormal formation of tissue; such as, a tumor or growth.

It serves no useful function, but it grows at the expense of the healthy organism.

histomoniasis
A serious avian disease caused by an ameboflagellate protozoan Histomonas meleagridis.

Common signs are depression, anorexia, loss of condition, and cyanosis of the skin of the head (blackhead); however, death may be sudden without any clinical signs.

histomorphology
The morphology, or the study of structure and form including the anatomy, histology, and cytology of the tissues of the body.
histomycosis
A deep dermatomycosis or a disease of body tissues which are deep within the body.

Histomycosis is caused by infection from fungi.

histone
One of the five kinds of proteins that are part of chromatin in eukaryotic cells.

Their positive charge attracts the negatively charged DNA that is folded around them into units called nucleosomes.

Histones also regulate some of the further folding of DNA in chromosomes about to undergo mitosis.

histonectomy
The excision, or cutting out, of tissue.
histoneurology
The microscopic anatomy of the nervous system; neurohistology.
histonomy
1. The laws of the development and arrangement of organic tissue.
2. The use of quantitative techniques in the analysis of histologic observations.
3. A law of the development and structure of the tissues of the body.
histonuria
Excretion of histones in the urine.
histopathology
1. The study of abnormal or diseased tissue or microscopically visible changes in diseased tissue.
2. The study of the structural alteration of cells and tissues caused by disease.
histophagous
Eating or subsisting on tissues; such as, certain protozoa, especially those ciliates, ectoparasitic or endoparasitic, in or on nonvital tissues of their hosts.
