☠️The human skeletal system is made up of 206 bones, organized into two main divisions: the axial skeleton (80 bones) and the appendicular skeleton (126 bones).
💀The axial skeleton includes:
✅️Skull (22 bones): 8 cranial (frontal, 2 parietal, occipital, 2 temporal, sphenoid, ethmoid) and 14 facial bones (2 nasal, 2 maxillae, 2 zygomatic, mandible, 2 lacrimal, 2 palatine, 2 inferior nasal conchae, vomer)
✅️Ear ossicles (6 bones): 2 malleus, 2 incus, 2 stapes
✅️Hyoid bone (1)
✅️Vertebral column (26 bones): 7 cervical, 12 thoracic, 5 lumbar, 1 sacrum (5 fused), 1 coccyx (4 fused)
✅️Thoracic cage (25 bones): 24 ribs (12 pairs) and the sternum
🦴The appendicular skeleton includes:
🔶️Pectoral girdle (4 bones): 2 clavicles, 2 scapulae.
🟡Upper limbs (60 bones): Each arm has 1 humerus, 1 radius, 1 ulna, 8 carpal bones, 5 metacarpals, and 14 phalanges.
🔷️Pelvic girdle (2 bones): 2 hip bones (each formed by the fusion of ilium, ischium, and p***s).
🟢Lower limbs (60 bones): Each leg has 1 femur, 1 patella, 1 tibia, 1 fibula, 7 tarsal bones, 5 metatarsals, and 14 phalanges.
💥Together, these bones provide structure, protect vital organs, and support movement, making the human skeleton a marvel of biological engineering.
