ANATOMY

Detailed explanation-1: -Long bones are mostly located in the appendicular skeleton and include bones in the lower limbs (the tibia, fibula, femur, metatarsals, and phalanges) and bones in the upper limbs (the humerus, radius, ulna, metacarpals, and phalanges).

Detailed explanation-2: -The forearm and the lower leg have two long bones each. In the forearm are the radius-on the thumb side of the forearm-and the ulna; in the lower leg are the tibia (the shinbone) and the fibula. The radius corresponds to the tibia and the ulna to the fibula.

Detailed explanation-3: -Long Bones They consist of a long shaft with two bulky ends or extremities. They are primarily compact bone but may have a large amount of spongy bone at the ends or extremities. Long bones include bones of the thigh, leg, arm, and forearm.

Detailed explanation-4: -Humerus. The humerus is the long bone between the shoulder and the elbow. It has the ball of the ball and socket of the shoulder (glenohumeral) joint. At the other end, it has its portion of the elbow joint.

Detailed explanation-5: -The femur is the large bone in the upper leg also known as the thigh bone. It is the longest bone in the body. The head (top) of the femur articulates or connects with the pelvic bone forming the hip joint, while the distal (bottom) part of the femur articulates with the tibia and kneecap forming the knee joint.
