The skeletal system, also known as the osteological system, is the framework of the body that provides support, protection, and movement. It consists of 206 bones in adults, which can be divided into two main categories: 1. Axial skeleton (80 bones): - Skull (22 bones) - Vertebral column (33 bones) - Ribcage (24 bones) - Sternum (3 bones) 2. Appendicular skeleton (126 bones): - Upper limbs (64 bones) - Pelvis (4 bones) - Lower limbs (64 bones) Some key bones in the skeletal system include: - Cranium (skull) - Vertebrae (spine) - Ribcage - Sternum (breastbone) - Scapula (shoulder blade) - Humerus (upper arm) - Radius and Ulna (forearm) - Carpals (wrist) - Metacarpals (hand) - Phalanges (fingers) - Pelvis - Femur (thigh) - Patella (kneecap) - Tibia and Fibula (lower leg) - Tarsals (ankle) - Metatarsals (foot) - Phalanges (...
