luumäärä

Luumäärä refers to the total number of bones in the human body. While it is commonly stated that an adult human has 206 bones, this number can vary slightly. Newborn babies have a significantly higher number of bones, around 300, as many bones are still separate and will fuse together as the child grows. This fusion process accounts for the reduction in bone count from infancy to adulthood.

The skeletal system serves several vital functions, including providing structural support, enabling movement through the attachment of muscles, protecting internal organs, producing blood cells in the bone marrow, and storing minerals like calcium. The bones are categorized into different types based on their shape and function, such as long bones, short bones, flat bones, and irregular bones.

The count of 206 bones in adults is a general guideline. Variations can occur due to factors like sesamoid bones (small bones embedded within tendons, the most notable being the patella or kneecap, though others can form in hands and feet) or accessory ossicles (extra bones that can occur in certain joints). These variations are usually not indicative of any medical condition and are often discovered incidentally through imaging. Therefore, while 206 is the standard number, the precise luumäärä can differ on an individual basis.
