Two types of human tails

Human tails are divided into two categories. The “psudotailsGrowths that look like a tail but are caused by spinal problems or tumors. “True Tails”On the other hand, there are muscles, blood vessels and nerves, but no bones like animals.

All babies are thought to emerge from the tail of an embryo that forms in utero, but is usually reabsorbed into the body to form the coccyx. The scans revealed that the tail was not the result of a spinal problem like spinal dysraphism – a condition where the spine does not develop properly and the tail appears at the base of the spine.

Doctors discharged the baby and re-examined him when he was two months old. She is of normal weight and height, and has a tail of 0.8 cm. Surgeons removed the tail in a small operation performed under local anesthesia. The little patient was discharged from the hospital the same day and had no complications.

They are most commonly seen in boys, and 1 in 17 children are affected by malformations of the brain or skull. They aren’t usually seen until after birth, and doctors don’t know what causes them—only one case runs in families.

Human ancestors and ape ancestors lost their tails when we split from the apes about 20 million years ago. In some faiths and cultures, human tails are considered sacred and are objects of worship.
