The skeletal system performs many functions which include:
1. Support the body.
2. Protect vital organs such as the heart.
3. Move the body.
Divisions of the skeletal system.
The frog skeletal system is divided into two regions the axial skeletal system and the appendicular system.
The axial skeleton consists of the skull, vertebral column, and sternum.
The appendicular system consists of the pectoral girdle, forelimbs, the pelvic girdle, and the hind limbs. Most of the bones correspond to those of the humans and bear identical names.
Comparison Of the Frog and The human
The axial and appendicular both make up a frog and human's skeletal system. For a frog, the skeletal system's main function is locomotion and maintaining posture. Although the human and frog skeletal system also protect vital organs the frog does not have any ribs whereas a human does. The frog also has less number of vertebrae, extended pelvic bones, and long bones of the hind legs. The frog skeletal system has l59 and the human has 206. The human's skeletal system is a moveable frame and is an efficient factory for producing red blood cells. The frog's skeletal system also produces red blood cell and all their bones are covered with a membrane called the periosteum from which they get their circulation nerves.
