The adult human skeletal system is composed of 206 bones and their accompanying joints. The skeleton provides the body with its shape, supports movement, protects our internal organs, produces blood cells, and stores certain minerals, such as calcium and phosphorus.
Our skeletal system can be divided into two main components – the axial and appendicular skeleton.
The axial skeleton consists of 80 bones from the skull, spinal column and thoracic cage (ribcage). On the other hand, the appendicular skeleton is composed of the limb bones – the arms and legs – as well as the pelvic girdle (hip bone).
The bones of the human body are instrumental to various processes. As an example, the appendicular skeleton serves as attachment points for skeletal muscles to allow movement.
Other bones, such as the skull bones, rib bones and sternum, protect vital organs from injury. The smallest bones in our body are the ossicles in the ear – these tiny bones aid in amplifying sound.
Inside the pelvic girdle, femurs, and other bones is a region of spongy tissue called bone marrow. The marrow contains stem cells, which can transform into different blood cell types.
Our labeled human skeleton diagram can be an informative reference for learning about the anatomy and physiology of human beings, and the vital role that the skeletal system plays in the body’s processes.
The human skeleton is an important part of the anatomy. This part of the body is used by humans for various functions. Among other things, it protects the internal organs, ensures that the muscles function properly, and gives them shape and structure. It is also the most important part of the central nervous system. It also has many other functions.
The human skeleton has two basic subdivisions: the spine and the anchor skeleton. The axial skeletal system is divided into six main parts: the thorax, the shoulder girdle, the arms and the forearms. The limb bones make up the hands. The proximal phalanges consist of ten bones, while the distal phalanges consist of eight bones.
The axial skeleton consists of the bones of the head and trunk of vertebrates, such as humans. The skull has sutures, which are fibrous joints found only in the skull. The skeletal system of the human body is called the axial skeleton. It consists of the skull, the bones of the lower jaw and the pectoral girdle.
The axial skeleton is a complex structure that includes 206 bones. It is divided into two main sections: the axial skeleton and the postaxial skeleton. The axial skeleton consists of the spine, which is the central axis of the body. It provides support and protection to the central organs and muscles and is composed of 80 bones. The lateral skeleton is the second part of the skeleton.
The axial skeleton has a variety of functions. It protects the organs in the abdominal cavity, gives them support and provides a surface for the muscles to attack. The thorax and the head are the two main divisions of the skeletal system. The skull supports the face and forms the brain cavity. The rib cage protects the vital organs in the chest. It is not uncommon for the femur to be displaced in a fall.
The skeletal system is made up of bones, joints and tendons. These bones support the organs and store minerals. The skeleton is divided into two parts: the compact bone and the spongy bone. The compact bone is the hardest and whitest of the two parts. It provides structural support. The spongy bone is soft and porous and has small pores. It stores the bone marrow and contains the organs that produce blood.
The axial skeleton consists of 80 bones. It forms the central structure of the skeletal system. The bones of the axial skeleton protect the heart and spinal cord. The skeleton also helps produce blood cells and regulates the endocrine system. This part of the body is made up of a variety of different organs, including the brain and digestive tract. A healthy skeletal system is essential for a person to function properly.
