Gross anatomy studies body structures visible to the naked eye, while microscopic anatomy studies tissues and cells with the aid of microscopes.
Gross and microscopic anatomy are the two primary divisions of human anatomy, the scientific study of the structure and morphology of the human body. Gross anatomy, also called macroscopic, regional, or topographical anatomy, examines structures visible to the unaided eye, including organs, muscles, bones, blood vessels, and body regions. Microscopic anatomy examines structures requiring magnification and includes histology, the study of tissues, and cytology, the study of cells. Anatomy can be studied regionally, such as by the head and neck, thorax, abdomen, pelvis, back, upper limb, and lower limb, or systemically, such as by the nervous, respiratory, circulatory, or musculoskeletal systems. Surface anatomy focuses on landmarks visible or palpable on the body's exterior and helps clinicians locate deeper structures. Anatomical knowledge is essential in medicine, surgery, diagnostic specialties, physical therapy, nursing, dentistry, and the visual arts, and is commonly learned through models, diagrams, textbooks, microscopy, and cadaver dissection.
Gross anatomy studies body structures visible to the naked eye, while microscopic anatomy studies tissues and cells with the aid of microscopes.
Microscopic anatomy includes histology, which examines tissue organization, and cytology, which examines cells.
Anatomy may be organized regionally by body areas or systemically by organ systems.
Surface anatomy uses external landmarks and body contours to determine the position of deeper anatomical structures.
Anatomical study is fundamental to medical education, clinical practice, surgery, diagnostic specialties, and accurate representation of the human figure in art.
The study of anatomical structures that can be seen without magnification.
The study of small anatomical structures that require microscopes for observation.
The study of the organization and structure of tissues.
The study of cells and their structures.
The study of the body according to specific regions such as the thorax, abdomen, or lower limb.
The study of the body according to organ systems such as the nervous or respiratory system.
The study of external anatomical landmarks used to identify the location of underlying structures.
