Anatomy
Learning Objectives
- Identify the major branches of anatomy and explain the purpose of each subdivision in clinical medicine
- Describe the regional organization of the human body and the sequence in which anatomical topics build on each other
- Recognize the anatomical basis for common clinical conditions covered across gross, microscopic, and developmental anatomy
- Explain how surface landmarks relate to underlying structures during physical examination
- Apply directional terminology, body planes, and anatomical position to describe structural relationships accurately
- Connect embryological development to adult anatomy, particularly for understanding congenital anomalies
- Use neuroanatomical principles to localize lesions based on motor and sensory deficits
Quick Answer
Anatomy is the foundational science of medicine — it is the study of the structure of the human body at every level, from the naked eye down to the cell. Medical students encounter anatomy through gross dissection, histological slides, imaging interpretation, and embryology. Clinically, anatomy explains why a patient with a humeral shaft fracture loses wrist extension (radial nerve), why an inguinal hernia tracks through the deep ring, and why a stroke in the left internal capsule causes right-sided weakness. Every physical examination finding, every surgical approach, and every imaging report depends on knowing anatomy accurately. This section builds from introductory concepts through regional and systems-based anatomy, giving you the framework to connect structure to function throughout your entire medical education.

Prerequisites: None — this is the entry point for Medicine. A basic understanding of biology cell structure is helpful but not required.
Related Topics: Physiology (how structures function), Pathology (how structures are altered by disease), Radiology (imaging interpretation relies on anatomical knowledge), Surgical Anatomy (clinical applications in operative settings).
Next Topics: Begin with Introduction to Human Anatomy, then progress through the regional gross anatomy topics (Upper Limb, Lower Limb, Thorax, Abdomen, Head and Neck) before moving to Neuroanatomy. Histology and Embryology can be studied in parallel.
