As we known, the human body continues to develop from the moment of conception until adulthood, after which growth typically stops. However, there are two body parts that never stop growing, even as we pass away. What are these? Let's explore further in the article below.
1. Overview of Human Growth and Development
Growth and development are biological characteristics of all living organisms, including humans. Human growth begins at the moment the egg is fertilized by sperm. Development, in essence, refers to a process of change in both quantity and quality that occurs inside the body.
Growth refers to the process of increasing body mass through cell multiplication, leading to tissue growth, organ formation, and overall body development. Starting from a fertilized egg, the body develops into a zygote, then an embryo, and continues to grow into an infant, child, and ultimately an adult.
For humans, the development of organs and body parts continues until adulthood, after which growth generally ceases. However, there are two parts of the body that persistently grow throughout life, even as we pass away
2. Which two body parts never stop growing?
The ears and the nose are the two parts of the body that continue to grow—and both are located on the head.
While most body parts begin to slow down and gradually stop growing after puberty, the ears and nose keep getting bigger, making them completely different from the rest of the body. This happens because the soft tissues around the cartilage in the ears and nose keep growing throughout life. As a result, in older age, the ears and nose often appear significantly larger compared to the rest of the face.
While some believe that nails and hair grow indefinitely, their growth depends on individual genetic factors.
A clear example of this is people who experience genetic hair loss (baldness), where hair growth eventually stops at a certain point, leading to thinning or balding. Therefore, ears and the nose is the most reliable and observable answer to the question of which parts of the human body never stop growing.
