ANATOMY

Detailed explanation-1: -The humerus and the femur are corresponding bones of the arms and legs, respectively. While their parts are similar in general, their structure has been adapted to differing functions.

Detailed explanation-2: -Diaphysis-Refers to the main part of the shaft of a long bone. Long bones, including the femur, humerus, and tibia, all have a shaft.

Detailed explanation-3: -Long bones are found in the arms (humerus, ulna, radius) and legs (femur, tibia, fibula), as well as in the fingers (metacarpals, phalanges) and toes (metatarsals, phalanges). Long bones function as levers; they move when muscles contract.

Detailed explanation-4: -The humerus is a long bone located in the upper arm, between the shoulder joint and elbow joint. The proximal humerus connects to the shoulder through the glenoid fossa of the scapula, forming the glenohumeral joint. The distal humerus articulates at the elbow to the radius and ulna in the forearm.

Detailed explanation-5: -Long bones are hard, dense bones that provide strength, structure, and mobility. 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.
