Venous Drainage of the Head and Neck

The veins of the head and neck collect deoxygenated blood and return it to the heart. Anatomically, the venous drainage can be divided into three parts: Venous drainage of the brain and meninges: Supplied by the dural venous sinuses. Venous drainage of the scalp and face: Drained by veins synonymous with the arteries of the face and scalp. These empty […]

Major Arteries of the Head and Neck

The head and neck receives the majority of its blood supply through the carotid and vertebral arteries. This article shall explore the anatomy of this arterial system – its anatomical course, branches, and clinical correlations. Carotid Arteries We shall start at the origin of the carotid arteries. The right common carotid artery arises from a bifurcation of […]

The Posterior Triangle of the Neck

The posterior triangle of the neck is an anatomical area located in the lateral aspect of the neck. In this article, we shall look at the anatomy of the posterior triangle of the neck – its borders, contents, subdivisions, and any clinical relevance. Borders Its boundaries are as follows: Anterior – posterior border of the […]

The Anterior Triangle of the Neck

The anterior triangle is a region located at the front of the neck. In this article, we shall look at the anatomy of the anterior triangle of the neck – its borders, contents and subdivisions. Note: it is important to note that all triangles mentioned here are paired; they are located on both the left and […]

Fascial Layers of the Neck

Fascia is an internal connective tissue which forms bands or sheets that surround and support muscles, vessels and nerves in the body. In the neck, these layers of fascia not only act to support internal structures, but also help to compartmentalise structures of the neck. There are two fascias in the neck – the superficial […]

Development of the Pituitary, Tongue and Thyroid

The pituitary gland, tongue and thyroid gland are midline structures located within the head and neck. In this article, we will look at the embryology of the pituitary, tongue and thyroid gland – their origin, development and clinical correlations. Pituitary Gland The pituitary gland is an endocrine gland located within the middle cranial fossa of […]

The Superior Vena Cava

The superior vena cava (SVC) is a large, valveless vein that conveys venous blood from the upper half of the body and returns it to the right atrium. In this article, we will look at the anatomy of the superior vena cava – its position, tributaries, and clinical correlations. Anatomical Position The superior vena cava […]

Tibiofibular Joints

The proximal and distal tibiofibular joints refer to two articulations between the tibia and fibula of the leg. These joints have minimal function in terms of movement but play a greater role in stability and weight-bearing. In this article, we shall look at the anatomy of the proximal and distal tibiofibular joints – their structures, neurovascular […]
