Skeletal System and its Divisions

The skeletal system is an essential part of the human body that provides support, protection, and movement. It is composed of bones, cartilage, ligaments, and tendons. The skeletal system can be divided into two main divisions: the axial skeleton and the appendicular skeleton.

1. Axial Skeleton: The axial skeleton forms the central axis of the body and consists of the skull, vertebral column, and thoracic cage. Here is a brief overview of each component:

- Skull: The skull is made up of the cranium and the facial bones. It protects the brain and houses the sensory organs such as the eyes, ears, and nose. - Vertebral Column: The vertebral column, also known as the spine or backbone, is composed of individual vertebrae. It provides support for the body, protects the spinal cord, and allows for movement. - Thoracic Cage: The thoracic cage includes the ribs, sternum (breastbone), and thoracic vertebrae. It protects the organs in the chest cavity, such as the heart and lungs.

2. Appendicular Skeleton: The appendicular skeleton consists of the bones of the limbs and the girdles that attach the limbs to the axial skeleton. It allows for movement and locomotion. Here are the main components:

- Upper Limbs: The upper limbs include the bones of the arms, forearms, wrists, and hands. They are connected to the axial skeleton through the pectoral girdle (shoulder girdle). - Lower Limbs: The lower limbs consist of the bones of the thighs, legs, ankles, and feet. They are connected to the axial skeleton through the pelvic girdle (hip girdle).

It's important to note that the skeletal system is not limited to bones alone. It also includes other connective tissues such as cartilage, ligaments, and tendons, which play crucial roles in supporting and connecting the bones.

I hope this overview of the skeletal system and its divisions helps you in your exam preparation. If you have any more specific questions or need further clarification, feel free to ask!
