Anatomical Areas

Overview

The upper limb contains numerous defined regions that serve as passageways for neurovascular structures and guide clinical examination. This section introduces the major anatomical areas including the axilla, cubital fossa, carpal tunnel and other important spaces that connect different compartments of the limb.

Key Structures

Articles describe the boundaries, contents and surface anatomy of key regions such as the axilla, triangular spaces, cubital fossa, and the anatomical snuffbox. Each topic is supported by diagrams to help learners visualise three-dimensional relationships and understand how these regions link the shoulder, arm, forearm and hand.

Clinical Relevance and Learning Focus

A clear grasp of these anatomical areas is essential for interpreting neurovascular compression, trauma and surgical access routes. Learners can apply this knowledge to procedures such as venepuncture, nerve block placement and examination of peripheral pulses.
