The human body and it's make up is extremely important to the way we function everyday. As our environment, food and medication changes the human anatomy or the effect on anatomy may alter. Therefore, it's always more to learn about human anatomy. There are always more disorders and cures and it is only through the study of the body and how it works that this information is found.
The human skeleton begins to develop 13 to 16 weeks after conception. At birth, a human has about 300 bones and cartilage elements, and many bones that will eventually fuse together are still separate, although joined by tough membranes. The malleable nature of cartilage allows for a baby’s easier passage through the birth canal.
As an adult, the skull consists of 26 cranial and facial bones fused together along unmovable joints called sutures, with the exception of the mandible, or jaw, which is attached at a moveable joint. At birth, many of those bones are not yet fused and instead are joined by fibrous membranes called fontanelles. The fontanelles are the so-called “soft spot” on an infant’s head. Eventually the fontanelles close as the bones grow together.
The process of changing cartilage to bone is called ossification, and begins before birth and continues into a person’s 20s. Ossification occurs when capillaries bring blood to bone-forming cells called osteoblasts. The osteoblasts then begin producing compact bone, covering the cartilage and eventually replacing it.
We have been learning everything we can about our own bodies for as long as man has been upright. The complex set of systems is well known but the brain and how it creates thought and emotion is still the final hurdle. We know what actions and processes take place but we still have a lot to learn about how thoughts and actions are registered from those synapsis.
No, I believe we already know a lot about human anatomy. I believe we still have a lot to learn about the workings of the human body especially when it comes to diseases and healing. I do think however that the anatomy of the body is very well known and studied.
