Skull ๐Ÿฆด๐Ÿ’€

What is it? Sits atop the vertebral column, divided into:

  • Cranium: Protects the brain ๐Ÿง 
  • Face: Guards eyes, ears, and contains teeth ๐Ÿ˜

Fun Fact: Ever wondered why helmets look like they do? They're designed to mimic the protective shape and functions of the skull! Think about that next time you're riding your bike ๐Ÿšด‍โ™€๏ธ.

Vertebral column - the backbone of our existence! ๐Ÿฆด๐ŸŽข

  • Overview: 33 vertebrae all stacked up, forming a column.

    • Movement? Oh boy! Bends forwards, backwards, sideways, and can even rotate ๐Ÿ”„.
    • Height Hack: This column makes up ~40% of our body height!
  • Vertebrae Types (Your body's very own Lego set! ๐Ÿงฑ)

    • Cervical (Neck): 7 pieces, smallest, most mobile. Think of nodding your head to your favorite song ๐ŸŽถ!
    • Thoracic (Mid-back): 12 pieces, attached to ribs, less twisty dance moves allowed.
    • Lumbar (Lower back): 5 big strong ones! They're the heroes taking most of our body weight like a weightlifting champion ๐Ÿ†.
    • Sacral (Base): 5 fused together = 1 strong vertebra. They're like the relay racers passing body weight to the pelvis and legs ๐Ÿƒ‍โ™€๏ธ.
    • Coccygeal (Tailbone): 4 fused together. Think of it as our little built-in tail!
  • Inner Secrets of Vertebrae ๐Ÿคซ

    • Vertebral Foramen: Holes in each vertebra where the spinal cord threads through, like stringing beads on a necklace.
    • Spinal Nerves: Branches out from the spinal cord, each lighting up a different area of the body like Christmas tree lights ๐ŸŽ„.
    • Intervertebral Discs: Cushion-y shock absorbers between each vertebra. They're like your body's jelly donuts! ๐Ÿฉ
  • Vertebral Curves ๐ŸŒŠ

    • Ever noticed the slight 'S' shape when looking at someone's side profile?
      • Thoracic and Sacral/Coccygeal: Curved inward. Original curves from when we were tiny baby burritos ๐ŸŒฏ.
      • Cervical and Lumbar: Curved outward. Added later when we decided holding our head up and standing was cool ๐Ÿ˜Ž.

    Did you know? These curves help us stay upright, absorb shocks, and make us flexible dancers!
