The first bone of the thumb ? 76 ANATOMY AND PHYSIOLOGY. The phalanges, or fingers, have three ranges of bones,while the thumb has but two. The bones of the hand andfingers are hollow, and enlarged at each extremity, like thebones of the arm and fore-arm. The articulation of thefingers is similar to that of the elbow and shoulder joints,rig. 30. Fg- 31-.

BONES OF THE LOWER EXTREMITIES. The lower extremities contain the femur, or thigh bone,the patella, or knee pan, the tibia, the fibula, seven bones ofthe tarsus, or instep, five metatarsal bones, and fourteen bonesof the toes; making in both limbs sixty. The femur is the longest bone in the system. It supportsthe weight of the head, trunk, and upper extremities. At itsupper extremity, the la
