The
field of anatomy is generally divided into macroscopic, or gross anatomy (not
requiring a microscope), and microscopic anatomy.
Gross anatomy includes
the subdivisions of regional anatomy,
systemic anatomy, developmental anatomy, and clinical anatomy.
Regional
anatomy studies specific regions of the body, such as the head and neck or
lower and upper limbs. Systemic anatomy studies different body systems, such as
the digestive system and reproductive system.
Developmental anatomy describes
the changes that occur from conception through physical maturity.
Clinical
anatomy includes medical anatomy (anatomical features that change during
illness) and radiographic anatomy (anatomical structures seen using various
imaging techniques).
The
two major subdivisions of microscopic anatomy are cytology and histology.
Cytology (from the Greek cyto,
meaning “cell”) is the study and
analysis of the internal structure of
individual cells. Histology (from the Greek histos,
meaning “web”) is the study and
examination of tissues.
