The muscles of the anterior compartment of the thigh are a group of muscles that (mostly) act to extend the lower limb at the knee joint.

They are collectively innervated by the femoral nerve (L2-L4), and recieve arterial supply from the femoral artery.

In this article, we shall look at the anatomy of the muscles of the anterior thigh – their actions, attachments and clinical correlations.

The heart is a fist-sized organ that pumps blood throughout your body. It's the primary organ of your circulatory system. Your heart contains four main sections (chambers) made of muscle and powered by electrical impulses. Your brain and nervous system direct your heart's function.

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.

The muscles in the medial compartment of the thigh are collectively known as the hip adductors.

There are five muscles in this group; gracilis, obturator externus, adductor brevis, adductor longus and adductor magnus.

All the medial thigh muscles are innervated by the obturator nerve, which arises from the lumbar plexus. Arterial supply is through the obturator artery.

The spinal cord provides innervation for the trunk and limbs through the
paired spinal nerves and their peripheral ramifications. Through them it
receives primary afferent fibres from peripheral receptors located in widespread
somatic and visceral structures. It also sends motor axons to skeletal
muscle and provides autonomic innervation of cardiac and smooth muscle
and secretory glands. Many functions are regulated by intraspinal reflex connections.
Profuse ascending and descending pathways link the spinal cord with

Filarial epididymoorchitis is a condition characterized by inflammation of the epididymis and testicles due to infection with filarial parasites. Filarial parasites are tiny, thread-like worms that are transmitted to humans through the bite of infected mosquitoes.

The symptoms of filarial epididymoorchitis can vary but commonly include swelling, pain, and tenderness in the affected testicle, as well as fever and chills. In some cases, the lymph nodes in the groin may also become swollen and tender.

Thyroid goiter, also known as an enlarged thyroid gland, can have various pathological features. It is typically characterized by an increase in the size and weight of the thyroid gland, which can be caused by a variety of underlying conditions.

A benign simple serous adenoma is a type of tumor that arises from the cells lining the surface of the ovary. It is usually a small, round, fluid-filled cyst that is typically found incidentally during imaging studies or surgery.

Pathologically, simple serous adenomas are characterized by a single layer of cells lining the cyst wall, with no evidence of atypia or invasion. The cells are typically small, cuboidal or columnar in shape, and have a uniform appearance. The cyst is usually filled with clear or pale yellow fluid, which is often described as serous.

A benign serous cystadenoma is a type of ovarian tumor that arises from the cells lining the surface of the ovary. It is typically a large cystic tumor that is filled with clear, watery fluid.

Pathologically, serous cystadenomas are characterized by a single layer of cells lining the cyst wall, with no evidence of atypia or invasion. The cells are typically columnar in shape, and have a uniform appearance. The cyst is usually filled with clear or pale yellow fluid, which is often described as serous.
