Study Notes
Bone Structure and Facts
- The human skeleton has 206 bones in adults and 350 bones in children.
- The femur is the longest and strongest bone, while the stapes (stirrup) in the middle ear is the smallest and lightest.
- The human foot has 26 bones, while the hand, including the wrist, has 54.
- Bones stop growing in length during puberty.
- The hyoid bone, located at the base of the tongue, is the only bone not connected to another.
- Bones are made up of minerals like calcium and phosphorus, as well as the protein collagen.
Bone Functions
- Bones provide structure and support, allow movement, and protect organs.
- They also produce red and white blood cells.
Formation and Types of Bones
- Ossification (osteogenesis) is the process of bone formation, starting between the sixth and seventh weeks of embryonic life.
- Germ layers, formed during gastrulation in the third week of human development, contribute to skeletal formation.
- The mesoderm germ layer develops into the skeletal system.
- Bones are classified into four types:
- Long bones: Long and thin (e.g., arms and legs)
- Short bones: Squat and cubed (e.g., wrist and ankle bones)
- Flat bones: Flattened and broad (e.g., skull, chest, and hip)
- Irregular bones: Peculiar shapes not conforming to the other types
Connective Tissue
- Tendon: Connects muscle to bone.
- Ligament: Tough fibrous band connecting bones together.
- Joint: Where two or more bones meet.
Numbers in the Body
- The human body has approximately 350 joints, 900 ligaments, and 4,000 tendons.
