The skull is composed of 22 bones that are fused together except for the mandible. These 21 fused bones are separate in children to allow the skull and brain to grow, but fuse to give added strength and protection as an adult. The mandible remains as a movable jaw bone and forms the only movable joint in the skull with the temporal bone. The bones ...
The hyoid is a small, U-shaped bone found just inferior to the mandible. The hyoid is the only bone in the body that does not form a joint with any other bone---it is a floating bone. The hyoid's function is to help hold the trachea open and to form a bony connection for the tongue muscles. The malleus, incus, and stapes---known collectively as the...
Twenty-six vertebrae form the vertebral columnof the human body. They are named by region: 1. Cervical(neck) - 7 vertebrae 2. Thoracic(chest) - 12 vertebrae 3. Lumbar(lower back) - 5 vertebrae 4. Sacrum- 1 vertebra 5. Coccyx(tailbone) - 1 vertebra With the exception of the singular sacrum and coccyx, each vertebra is named for the first letter of i...
The sternum, or breastbone, is a thin, knife-shaped bone located along the midline of the anterior side of the thoracic region of the skeleton. The sternum connects to the ribs by thin bands of cartilage called the costal cartilage. There are 12 pairs of ribs that together with the sternum form the ribcage of the thoracic region. The first seven ri...
The pectoral girdle connects the upper limb (arm) bonesto the axial skeleton and consists of the left and right clavicles and left and right scapulae. The humerus is the bone of the upper arm. It forms the ball and socket joint of the shoulder with the scapula and forms the elbow jointwith the lower arm bones. The radius and ulna are the two bones ...
Formed by the left and right hip bones, the pelvic girdle connects the lower limb (leg) bonesto the axial skeleton. The femur is the largest bone in the body and the only bone of the thigh (femoral) region. The femur forms the ball and socket hip joint with the hip bone and forms the knee jointwith the tibia and patella. Commonly called the kneecap...
The skeleton makes up about 30-40% of an adult's body mass. The skeleton's mass is made up of nonliving bone matrix and many tiny bone cells. Roughly half of the bone matrix's mass is water, while the other half is collagen protein and solid crystals of calcium carbonate and calcium phosphate. Living bone cells are found on the edges of bones and i...
All of the bones of the body can be broken down into five types: long, short, flat, irregular, and sesamoid. 1. *Long. *Long bones are longer than they are wide and are the major bones of the limbs. Long bones grow more than the other classes of bone throughout childhood and so are responsible for the bulk of our height as adults. A hollow medullar...
The long bones of the body contain many distinct regions due to the way in which they develop. At birth, each long bone is made of three individual bones separated by hyaline cartilage. Each end bone is called an epiphysis (epi = on; physis = to grow) while the middle bone is called a diaphysis (dia = passing through). The epiphyses and diaphysis g...
An articulation, or joint, is a point of contact between bones, between a bone and cartilage, or between a bone and a tooth. Synovial joints are the most common type of articulation and feature a small gap between the bones. This gap allows a free range of motion and space for synovial fluid to lubricate the joint. Fibrous joints exist where bones ...
- Skeletal system. The skeletal system is composed of bones and cartilages. There are two parts of the skeleton; axial and appendicular. The axial skeleton consists of the bones of the head and trunk.
- Muscular system. The muscular system consists of all the body muscles. There are three muscle types; smooth, cardiac and skeletal muscles. Smooth muscle is found within walls of blood vessels and hollow organs such as the stomach or intestines.
- Cardiovascular system. The cardiovascular system is comprised of the heart and the circulatory system of blood vessels. The heart is composed of four chambers; two atria and two ventricles.
- Respiratory system. The respiratory system consists of a series of organs; the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles and lungs (alveoli).

The bones of the human skeleton are divided into two groups. The appendicular skeleton includes all the bones that form the upper and lower limbs, and the shoulder and pelvic girdles. The axial skeleton includes all the bones along the body’s long axis. Let’s work our way down this axis to learn about these structures and the bones that ...

Hello everyone! It's Megan from Kenhub here, and in today’s tutorial, we're going to be looking at the skeletal system of the body. The human skeleton is a framework that gives your body shape and support and essentially stops you from being just a blob on the floor. Think of it like the wooden beams that make up the internal framework of a ...
