Appendicular skeleton includes

The appendicular skeleton includes the bones of the limbs and their associated girdles. It is one of the two main divisions of the human skeleton, with the other being the axial skeleton. The appendicular skeleton provides support and enables movement of the limbs.

1. Girdles
The appendicular skeleton includes two girdles: the pectoral girdle and the pelvic girdle.

- Pectoral Girdle: The pectoral girdle, also known as the shoulder girdle, consists of the clavicle (collarbone) and the scapula (shoulder blade). It connects the upper limbs to the axial skeleton, allowing for the movement of the arms and shoulders.

- Pelvic Girdle: The pelvic girdle, also known as the hip girdle, consists of two hip bones, also called coxal bones or innominate bones. The pelvic girdle connects the lower limbs to the axial skeleton and supports the weight of the body.

2. Limbs
The appendicular skeleton also includes the bones of the limbs, including the upper limbs (arms) and the lower limbs (legs).

- Upper Limbs: The upper limbs consist of the humerus (upper arm bone), radius and ulna (forearm bones), carpals (wrist bones), metacarpals (hand bones), and phalanges (finger bones). These bones provide support and allow for various movements of the arms, hands, and fingers.

- Lower Limbs: The lower limbs consist of the femur (thigh bone), tibia and fibula (leg bones), tarsals (ankle bones), metatarsals (foot bones), and phalanges (toe bones). These bones provide support and enable movements such as walking, running, and jumping.

3. Function
The appendicular skeleton plays a crucial role in maintaining posture, supporting the body's weight, and facilitating movement. The girdles connect the limbs to the axial skeleton and provide a stable base for the movement of the arms and legs. The bones of the limbs allow for various movements and actions, such as reaching, grasping, walking, running, and performing fine motor skills.

4. Conclusion
In conclusion, the appendicular skeleton includes the girdles and the bones of the limbs. It provides support, stability, and enables movement of the limbs, allowing for a wide range of activities and functions.
