Explanation:

1. A joint is where two or more bones meet. A tendon connects muscle to bone, a synapse is a junction between nerve cells, and a ligament connects bone to bone.
2. The skeletal system surrounds and protects internal organs. The endocrine system regulates hormones, the circulatory system transports blood, and the respiratory system is for gas exchange.
3. Long bones are in the legs (e.g., femur). The back has vertebrae (irregular bones), the chest has ribs (flat bones), and the skull has flat bones.
4. The frontal, occipital, and temporal are cranial bones. The metacarpal is in the hand.
5. The parietal bones form the crown and upper sides of the head. The cheek has the zygomatic bone, the upper jaw is the maxilla, and the nose bridge has nasal bones.
6. The occipital bone is at the back of the skull. The temporal is on the sides, the parietal is on top, and the frontal is at the front.
7. The mandible is the lower jaw and largest facial bone. The nasal is for the nose, the lacrimal is near the eye, and the maxillae are the upper jaws.
8. The 8 carpals make up the wrist. The knee has the patella, the hand has metacarpals and phalanges, and the elbow has the ulna and radius.
9. The 5 metacarpals form the palm. Carpals are in the wrist, maxillae are in the upper jaw, and phalanges are fingers/toes.
10. The fibula is the outer, narrower lower leg bone. The femur is the thigh bone, the patella is the kneecap, and metatarsals are in the foot.
