The Femoral Triangle

The femoral triangle is a wedge-shaped area located within the superomedial aspect of the anterior thigh. It acts as a conduit for structures entering and leaving the anterior thigh. In this article, we shall look at the anatomy of the femoral triangle – its borders, contents, and clinical relevance. Borders The femoral triangle consists of […]

Muscles in the Posterior Compartment of the Leg

The posterior compartment of the leg contains seven muscles, organised into two layers – superficial and deep. The two layers are separated by a band of fascia. The posterior leg is the largest of the three compartments. Collectively, the muscles in this area plantarflex and invert the foot. They are innervated by the tibial nerve, […]

Muscles in the Anterior Compartment of the Leg

There are four muscles in the anterior compartment of the leg: tibialis anterior, extensor digitorum longus, extensor hallucis longus and fibularis tertius. Collectively, they act to dorsiflex and invert the foot at the ankle joint.  The extensor digitorum longus and extensor hallucis longus also extend the toes. The muscles in this compartment are innervated by the deep fibular […]

Muscles in the Lateral Compartment of the Leg

There are two muscles in the lateral compartment of the leg; the fibularis longus and brevis (also known as peroneal longus and brevis). The common function of the muscles is eversion – turning the sole of the foot outwards. They are both innervated by the superficial fibular nerve. In this article, we shall look at the anatomy of […]

The Fibula

The fibula is a bone located within the lateral aspect of the leg. Its main function is to act as an attachment for muscles, and not as a weight-bearer. It has three main articulations: Proximal tibiofibular joint – articulates with the lateral condyle of the tibia. Distal tibiofibular joint – articulates with the fibular notch of the […]

The Tibia

The tibia is the main bone of the lower leg, forming what is more commonly known as the shin. It expands at its proximal and distal ends; articulating at the knee and ankle joints respectively. The tibia is the second largest bone in the body and it is a key weight-bearing structure. In this article, we shall look at anatomy of […]

Anatomical Terms of Movement

Anatomical terms of movement are used to describe the actions of muscles upon the skeleton. Muscles contract to produce movement at joints, and the subsequent movements can be precisely described using this terminology. The terms used assume that the body begins in the anatomical position. Most movements have an opposite movement – also known as […]

The Popliteal Fossa

The popliteal fossa is a diamond shaped area located on the posterior aspect of the knee. It is the main path by which vessels and nerves pass between the thigh and the leg. In this article, we shall look at the anatomy of the popliteal fossa – its borders, contents and clinical correlations. Borders The […]

Muscles in the Posterior Compartment of the Thigh

The muscles in the posterior compartment of the thigh are collectively known as the hamstrings. They consist of the biceps femoris, semitendinosus and semimembranosus, which form prominent tendons medially and laterally at the back of the knee. As group, these muscles act to extend at the hip, and flex at the knee. They are innervated by the sciatic nerve (L4-S3). […]

The Knee Joint

The knee joint is a hinge type synovial joint, which mainly allows for flexion and extension (and a small degree of medial and lateral rotation). It is formed by articulations between the patella, femur and tibia. In this article, we shall examine the anatomy of the knee joint – its articulating surfaces, ligaments and neurovascular supply.
