Appendicular division

The skeletal system is made up of all of the bones, cartilages, and ligaments that support and form the body and its structures, while the skeleton is made up of the bones. There are 206 called bones in an adult’s body. Since certain bones fuse together during childhood and adolescence, younger people have more bones. The skeleton’s primary functions are to provide a solid, internal structure that protects internal organs and maintains the body’s weight, as well as a structure upon which muscles can work to generate body movements. Essential minerals like calcium and phosphate are also stored primarily in the bones of the skeleton. The fat-storing and blood-cell-producing tissue of the body is housed in the bone marrow.
Many of the bones in the head, neck, chest, and back are part of the axial skeleton, which forms the body’s vertical, central axis (Figure 7.1.1). The brain, spinal cord, heart, and lungs are all protected by it. It also acts as the attachment point for muscles that move the head, neck, and back, as well as muscles that move the limbs by acting around the shoulder and hip joints.

All of the bones, cartilages, and ligaments in the body that sustain and form the body and its components are part of the skeletal system. The skeleton is made up of the body’s bones. The skeleton of an adult contains 206 bones. Since certain bones fuse together during childhood and adolescence to form an adult skeleton, younger people have more bones. The skeleton’s primary functions are to provide a rigid, internal framework that can support the body’s weight against gravity and to provide a structure upon which muscles can work to generate body movements. The lower skeleton is designed to provide support when walking or running. The upper skeleton, on the other hand, has greater strength and ranges of motion, allowing you to raise and hold objects as well as turn your head and trunk.
The skeleton has protection and storage functions in addition to providing stability and movement for the body. It protects the brain, spinal cord, heart, lungs, and pelvic organs, among other internal organs. The main storage place for essential minerals including calcium and phosphate is the skeleton’s bones. The fat-storing and blood-cell-producing tissue of the body is housed in the bone marrow.

What are the two major divisions of the human skeleton

The Slovak National Museum in Bratislava, Slovakia, has this rather macabre exhibit (Figure 11.3.1). The skulls are supposed to reflect natural skeletal anatomy in humans. The axial skeleton, one of the two main divisions of the human skeleton, includes the skull. The appendicular skeleton is the other division.
There are 80 bones in the axial skeleton (shown in blue in Figure 11.3.2). It also contains the rib cage and the vertebral spine, in addition to the skull. The three tiny ossicles in the middle ear (hammer, anvil, and stirrup) and the hyoid bone in the throat, to which the tongue and several other soft tissues are attached, are also included.
The skull is a bony structure for the head that is part of the human skeleton. It is made up of 22 bones in total. The cranium, which houses the brain, has eight bones and the face has fourteen.
The entire upper part of the skull is made up of the cranium. It is made up of eight bones: one frontal bone, two parietal bones, two temporal bones, one occipital bone, one sphenoid bone, and one ethmoid bone, as shown in Figure 11.3.3. The nasal cavity and the brain are separated by the ethmoid bone. The sphenoid bone is one of many bones that help shape the eye sockets, along with the frontal bone. The cranium’s other bones are wide and plate-like. They encase and shield the brain. Major blood vessels and nerves have holes in the bottom of the skull. The foramen is a wide gap that separates the spinal cord and the brain.
