Loin

Loin (/lɔɪn/) is a term often used in medical and anatomical contexts to refer to the part of the human body that is located on both sides of the backbone between the ribs and the pelvis.

Etymology

The term "loin" originates from the Old French loigne, which is derived from the Latin lumbus meaning 'flank'.

Anatomy

The loin region in humans is situated in the lower part of the back, often referred to as the lumbar region. It is located between the thoracic region of the back (the area of the back located between the neck and the abdomen) and the sacral region (the area of the back located between the pelvis and the tailbone). The loin region is primarily composed of the lumbar vertebrae, which are part of the larger vertebral column or spine.
