Inferior pubic ramus
Inferior Pubic Ramus
The Inferior Pubic Ramus (pronunciation: in-fee-ri-or pyoo-bik ray-mus) is a significant anatomical structure in the human pelvis.
Etymology
The term originates from the Latin words 'Inferior' meaning 'lower', 'Pubis' referring to the 'pubic bone', and 'Ramus' meaning 'branch'. Thus, the term 'Inferior Pubic Ramus' can be translated as 'the lower branch of the pubic bone'.
Anatomy
The Inferior Pubic Ramus is a part of the pelvic bone and extends from the body of the pubis, one of the three bones that make up the hip bone. It projects downwards and laterally. It is thin and flat, and it forms a large part of the obturator foramen, a large opening in the hip bone.
The Inferior Pubic Ramus articulates with the ischium, another bone of the hip, to form the ischiopubic ramus. This structure is important in the attachment of several muscles, including the gracilis muscle and the adductor muscles of the thigh.
