What are the two types of girdles found in the human skeleton?

The two types of girdles found in the human skeleton are the pectoral girdle and the pelvic girdle. The pectoral girdle, also known as the shoulder girdle, consists of the clavicles (collarbones) and the scapulae (shoulder blades), which support the upper limbs and provide attachment points for muscles. The pelvic girdle, on the other hand, is formed by the fusion of the ilium, ischium, and pubis bones, creating a sturdy base that supports the lower limbs and houses vital organs within the pelvic cavity.

Identifying these girdles is significant in understanding human anatomy as they play critical roles in movement and support. The pectoral girdle facilitates the range of motion of the arms, while the pelvic girdle supports weight and is involved in locomotion and balance. This distinction between the two girdles highlights their individual functions and importance in the skeletal system.
