Inferior ramus

Inferior Ramus is a term used in anatomy to refer to the lower branch of a structure. The term 'ramus' is Latin for 'branch', and 'inferior' denotes the lower position of the structure. The term is often used in the context of the pelvis, where it refers to the lower part of the pubic bone, but it can also refer to other structures in the body.

Anatomy

The inferior ramus of the pubic bone, together with the superior ramus, forms a part of the pelvic girdle. It extends from the body of the pubic bone to the ischium, forming the lower part of the obturator foramen, a large opening in the pelvic bone.

The inferior ramus is important in the attachment of several muscles, including the gracilis muscle, the adductor magnus muscle, and the obturator externus muscle. These muscles play a crucial role in the movement and stability of the hip joint.

Clinical significance

Due to its location and role in the body, the inferior ramus can be involved in several medical conditions. Fractures of the inferior ramus can occur as a result of trauma, such as a fall or a car accident. These fractures can cause pain and difficulty walking, and may require surgical intervention.

In addition, the inferior ramus can be affected by diseases such as osteoporosis, which can weaken the bone and increase the risk of fractures. Other conditions, such as pelvic inflammatory disease, can also affect the inferior ramus and cause pain or other symptoms.
