The Axillary Nerve

The axillary nerve is a major peripheral nerve of the upper limb. In this article, we shall look at the anatomy of the axillary nerve – its anatomical course, motor and sensory functions, and any clinical correlations. Overview Spinal roots: C5 and C6. Sensory functions: Gives rise to the upper lateral cutaneous nerve of arm, which innervates […]

The Brachial Plexus

The brachial plexus is a network of nerve fibres that supplies the skin and musculature of the upper limb. It begins in the root of the neck, passes through the axilla, and runs through the entire upper extremity. The plexus is formed by the anterior rami (divisions) of cervical spinal nerves C5, C6, C7 and C8, and […]

Bones of the Hand: Carpals, Metacarpals and Phalanges

The bones of the hand provide support and flexibility to the soft tissues. They can be divided into three categories: Carpal bones (Proximal) – A set of eight irregularly shaped bones. These are located in the wrist area. Metacarpals – There are five metacarpals, each one related to a digit Phalanges (Distal) – The bones […]

The Cubital Fossa

The cubital (anticubital) fossa is a triangular-shaped depression over the anterior aspect of the elbow joint. It represents an area of transition between the anatomical arm and the forearm, and conveys several important structures between these two areas. In this article, we shall look at the anatomy of the cubital fossa – its borders, contents and […]

Arterial Supply to the Upper Limb

The arterial supply to the upper limb is delivered via five main vessels (proximal to distal): Subclavian artery Axillary artery Brachial artery Radial artery Ulnar artery In this article, we shall look at the anatomy of the arteries of the upper limb – their anatomical course, branches and clinical correlations. Subclavian Artery The arterial supply […]

The Radius

The radius is a long bone in the forearm. It lies laterally and parallel to ulna, the second of the forearm bones. The radius pivots around the ulna to produce movement at the proximal and distal radio-ulnar joints. The radius articulates in four places: Elbow joint – Partly formed by an articulation between the head […]

The Humerus

The humerus is a long bone of the upper limb, which extends from the shoulder to the elbow. The proximal aspect of the humerus articulates with the glenoid fossa of the scapula, forming the glenohumeral joint. Distally, at the elbow joint, the humerus articulates with the head of the radius and trochlear notch of the […]

Anatomical Terms of Location

The anatomical terms of location are vital to understanding and using anatomy. They help to avoid any ambiguity that can arise when describing the location of structures. In this article, we shall look at the basic anatomical terms of location, and examples of their use within anatomy. Note: There are some anatomical terms that are specifically […]
