Final answer:
The removable partial skeleton to which the remaining units are attached is known as the appendicular skeleton. It consists of 126 bones including the limb bones and the girdle bones that secure the limbs to the axial skeleton.
Step-by-step explanation:
The skeleton of the removable partial to which the remaining units are attached is known as the appendicular skeleton. This includes all the bones of the upper and lower limbs, plus the bones that attach each limb to the axial skeleton. The adult appendicular skeleton consists of 126 bones, which are classified into the limb bones themselves and the girdle bones that anchor the limbs to the thoracic cage and vertebral column. The pectoral girdle forms the shoulder region and connects the upper limbs to the body, while the pelvic girdle attaches the lower limbs. It's essential for movement and support within the body, playing a significant role in various functions and activities we undertake daily.
Looking at the structure and distribution of the appendicular skeleton, it is subdivided into various components. These components are the bones within the limbs, which are directly involved in movement and function, and the girdles, which provide points of attachment. The pectoral girdle consists of the clavicle and scapula, securing the upper limb to the body's axial skeleton. The pelvic girdle, comprised of the hip bones, connects the lower limb to the axial skeleton.
The construction of the appendicular skeleton can vary widely in nature, including single elements, bivalves, multivalves, plates, ossicles, or bones. In the case of human anatomy, the appendicular skeleton connects with the axial skeleton to provide a comprehensive supporting structure within the body, facilitating movement and a range of activities.
