Sub-section 1.2: Main Bone Teams
The 206 bones within the human physique are categorized into a number of main teams, every serving distinct capabilities:
- Axial skeleton (80 bones): Cranium, backbone, and rib cage, offering help and safety for very important organs.
- Appendicular skeleton (126 bones): Limbs (legs and arms) and shoulder and hip girdles, facilitating motion and offering attachment factors for muscular tissues.
Part 2: Distinctive Bone Traits
Sub-section 2.1: Bone Density and Power
The human skeleton is remarkably sturdy and resilient as a result of presence of a tough mineral referred to as calcium hydroxyapatite. This mineral crystallizes inside the collagen fibers that make up bone tissue, offering rigidity and resistance to bending and compression.
Sub-section 2.2: Bone Progress and Transforming
All through our lives, our bones endure a steady means of progress, reworking, and restore. Specialised cells referred to as osteoblasts and osteoclasts work collectively to construct and break down bone tissue, making certain that our skeleton adapts to altering wants and repairs itself when broken.
Part 3: The Bones We Carry
Sub-section 3.1: Head and Neck
The cranium consists of twenty-two bones that shield the mind and facial buildings. The neck is made up of seven vertebrae, offering flexibility and help for the top.
