Three parts of the limb of a rat from the proximal to the distal end are

The correct option is stylopodium, zeugopodium and autopodium.

To understand the arrangement of the parts of a tetrapod limb (such as that of a rat) from the proximal end (closer to the body attachment) to the distal end (further away from the body), we can divide the limb skeleton into three primary anatomical regions along the proximodistal axis:
1. Stylopodium: This is the most proximal segment of the limb. In the forelimb, it is represented by the humerus (upper arm bone), and in the hindlimb, it is represented by the femur (thigh bone).
2. Zeugopodium: This is the middle segment of the limb. In the forelimb, it consists of the radius and ulna (forearm bones), while in the hindlimb, it consists of the tibia and fibula (shank/shin bones).
3. Autopodium: This is the most distal segment of the limb, comprising the hands or feet. In the forelimb, it contains the carpals, metacarpals, and phalanges (wrist and digits), while in the hindlimb, it contains the tarsals, metatarsals, and phalanges (ankle and digits).

Therefore, the correct anatomical sequence of the limb segments from the proximal to the distal end is stylopodium, followed by zeugopodium, and finally autopodium.
