Complete answer:
Limbs are arms and legs in the human body. Forelimbs are the ones that are found in the front part of the body i.e arms. Hind limbs are those that are found in the back part of the body I.e legs.

Human arms have hands which are specialised organs allowing them to grasp and manipulate the objects. Fore limbs are shorter than the hind limbs. This is due to taller bones present in the hind limbs as compared to fore limbs.

Forelimb is located between the wrist and elbow.
The bones present in the forelimbs are — scapula, humerus, radius, ulna, carpals (8), metacarpals (5) and phalanges (14).
The humerus is a single bone present in the upper arm. Ulna and radius are two paired bones. Ulna lies medially and radius lies laterally.

The bones present in hind limbs are — femur, patella, tibia, fibula, digits, tarsals and metatarsals. The femur is the bone of the thigh. Patella is the kneecap of the limb. Tibia is the largest weight bearing limb.

Note: Each limb is made up of 30 bones. The bones present in the forelimbs are — scapula, humerus, radius, ulna, carpals (8), metacarpals (5) and phalanges (14). The bones present in hind limbs are — femur, patella, tibia, fibula, digits, tarsals and metatarsals.
