MEDICAL PHYSIOLOGY

Detailed explanation-1: -The thigh bone (femur) is a long bone. A long bone has a shaft and two ends. Some bones in the fingers are classified as long bones, even though they are short in length.

Detailed explanation-2: -All of the bones in the arms and legs, except the patella, and bones of the wrist, and ankle, are long bones.

Detailed explanation-3: -There are four types of bones in your body: long bones, short bones, flat bones, and irregular bones. The femur-the only bone in the upper leg-is a long bone.

Detailed explanation-4: -Long bones function to support the weight of the body and facilitate movement. 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-5: -Structurally, the femur is a long bone, meaning its length is greater than its width, while the patella, a sesamoid bone, is small and round. Functionally, the femur acts as a lever, while the patella protects the patellar tendon from compressive forces.
