anatomies

Anatomies are the plural form of anatomy, the branch of biology that studies the structure of organisms and their parts. Anatomic study describes how organs, tissues, and cells are organized and interrelated to form a functioning organism. It encompasses the macroscopic (gross) level and microscopic (histology) level, as well as comparative and developmental perspectives.

Major subfields include human anatomy, regional anatomy (head and neck, thorax, abdomen, pelvis, limbs), systemic anatomy (skeletal, muscular, nervous, circulatory, respiratory, digestive, urinary, reproductive, endocrine, immune), and surface anatomy (landmarks). Comparative anatomy examines similarities and differences across species; developmental or embryological anatomy studies changes from conception to birth.

Historically based on dissection, modern anatomy uses imaging (X-ray, CT, MRI), endoscopy, and histological techniques. Education often emphasizes both gross anatomy and histology. Anatomy is foundational to medicine and other life sciences.

Earliest systematic descriptions appeared in ancient civilizations; over centuries, anatomy evolved from dissection-focused study to integrated with physiology and clinical practice.

Anatomy and physiology form complementary disciplines: anatomy describes structure, while physiology explains function. Together they provide the basis for understanding health, disease, and the design of medical treatments.
