Body surface anatomy
After completing this study unit you will be able to:
- Name the main structures visible on the anterior and posterior surfaces of the human body.
- Describe the location, appearance and relationships of palpable anatomical structures.
Surface anatomy teaches us about the main anatomical features visible on the surface of the human body. We use this knowledge to identify inner anatomical structures according to their visible features.
A good understanding of surface anatomy is key to interpreting normal and abnormal anatomy in clinical settings, such as medical imaging procedures and clinical examination. Many aspects of surface anatomy between the sexes are similar but there are a few differences which mainly relate to sexual differentiation during development.
