Category A - Anatomy

Subheadings

/anatomy & histology - Used with organs, regions, and tissues for normal descriptive anatomy and histology.

Morphologic study of the liver.
LIVER/ *anat

/cytology - Used for normal cellular morphology of cells, tissues, or organs.

Structure of hepatocytes.
HEPATOCYTES / * cytol

/pathology - Used for organ, tissue, or cell structure in disease.

Morphology of the liver in liver cirrhosis.
LIVER CIRRHOSIS / * pathol
LIVER / * pathol

/pathology is one of the most misused and overused subheadings. It should be used ONLY if the article discusses anatomical, histological changes in the DISEASE, NOT as a substitute for "disease"

/ultrastructure Used with tissues and cells (including neoplasms) and microorganisms for microanatomic structures, generally below the size visible by light microscopy.
Unlike the subheadings /anatomy & histology and /cytology, which are reserved for normal structure and /pathology which is reserved for abnormal structure, /ultrastructure is used for BOTH normal and pathological subcellular structure. When /ultrastructure is indexing for pathological ultrastructure, it is not nesecary to add /pathology as a second subheading.

Fine structure of liver endoplasmic reticulum
LIVER / * ultrastruct
ENDOPLASMIC RETICULUM / * ultrastruct

/abnormalities Used with organs for congenital defects producing changes in the morphology of the organ.
