What is the human skeleton made up of?
Q: What is the human skeleton made up of?
A: The human skeleton is made up of about 300 bones at birth, but as some bones join together, there are 206 bones in adulthood.
Q: How can the human skeleton be divided?
A: The human skeleton can be divided into the axial skeleton and the appendicular skeleton. The axial skeleton is formed by the vertebral column, rib cage, skull and other associated bones. The appendicular skeleton is attached to the axial skeleton and consists of the shoulder girdle, pelvic girdle and upper and lower limb bones.
Q: What are the main functions of the human skeleton?
A: The main functions of the human skeletal system are support, movement, protection, production of blood cells, storage of minerals and endocrine regulation.
Q: Are there any differences between male and female skeletons?
A: Yes, there are subtle differences between male and female skeletons in terms of morphology such as skull shape, teeth structure long bone size and pelvis shape. Generally speaking female skeletal elements tend to be smaller than corresponding male elements. Additionally females have wider hips which allow for easier childbirth due to a larger head size on newborns compared to other primates. Males do not have penile bones which is an adaptation to an upright stance in humans.
Q: Why do females have wider hips than males?
A: Females have wider hips than males because this allows for easier childbirth due to a larger head size on newborns compared to other primates. This wider hip structure gives a birth channel that allows for foetuses to pass through more easily during delivery.
Q: How does having no penile bone help humans with their upright stance?
A: Having no penile bone helps humans with their upright stance because it makes it easier for them move around without being hindered by having a rigid bone structure in that area when walking or running etc..
