Harrison's groove
Harrison's Groove
Harrison's Groove (/hɑːrɪsənz ɡruːv/), also known as Harrison's Sulcus, is a horizontal groove along the lower border of the thorax in children. It is named after the British physician, Sir William Harrison, who first described it in the late 19th century.
Etymology
The term "Harrison's Groove" is derived from the name of Sir William Harrison, a British physician who first described this medical condition. The word "groove" is derived from the Old English word "grafan," which means to dig or engrave.
Description
Harrison's Groove is a physical sign often seen in children with chronic asthma or other conditions that cause chronic respiratory distress. It is caused by the inward pull of the diaphragm on the lower ribs during inspiration. This results in a horizontal groove or depression along the lower border of the thorax.
