5 days ago · human skeleton, the internal skeleton that serves as a framework for the body. This framework consists of many individual bones and cartilages. There also are bands of fibrous connective tissue —the ligaments and the tendons —in intimate relationship with the parts of the skeleton. This article is concerned primarily with the gross ...

Oct 25, 2023 · If bones provide the framework, the joints provide the flexibility by permitting movement. A joint, or articulation, is the junction between two or more bones. There are three main types: fibrous, cartilaginous, and synovial. The latter allows the greatest freedom of movement and are the most well known in anatomy.

This bone forms the forehead, the roof of the orbital cavity (eye socket), and the root of the nose. A newborn has a frontal bone that consists of two parts, separated by the frontal suture. However, the parts fuse to form a single bone, by the time a child is eight years old.
One bone from each side joins behind the frontal bone to form the sides and the roof of the cranium. There are 2 parietal bones, and each bone is roughly quadrilateral in shape.
There are 2 temporal bones in all, one on each side below the parietal bones. The temporal bones are located lateral to the temporal lobes of the brain, and each bone consists of five parts.
This is a single bone that is present at the back and lower part of the cranium, just behind the parietal and temporal bones. It has an oval aperture, known as the foramen magnum, through which the spinal cord enters the skull. Vertebral arteries, spinal nerves and ligaments that join the skull to the vertebrae, pass through this aperture.
This is a single bone that is situated at the base of the skull in front of the temporal bones and basilar part of the occipital bone. It’s shape resembles that of a butterfly, and it is one of the seven bones that form the orbital cavity or eye socket.
This is a light and spongy bone that is situated in the anterior part of the base of the cranium. It lies between the two orbits, at the roof of the nasal cavity, separating the brain from the nasal cavity. It is one of the seven bones that form the orbital cavity, and consists of three parts.

This is the lower jawbone, and is known as the inferior maxillary bone. It is U-shaped and is the largest and strongest bone of the face. The mandible of a newborn consists of two halves that fuse at the mental symphysis during the first year. Each half of the mandible has a horizontal body and a vertical ramus at the posterior end of the body. The...
The maxilla, or the upper jawbone, holds the teeth of the upper jaw, and forms the walls of the orbital cavity. It also contributes to the roof of the oral cavity, and the lateral walls and floor of the nasal cavity. The mandible is actually two bones that are fused along the palatal fissure. Failure of fusion of the two bones before birth, can lea...
B. Divisions of the Skeletal System. The skeletal system includes all of the bones, cartilages, and ligaments of the body that support and give shape to the body and body structures. The skeleton consists of the bones of the body. For adults, there are 206 bones in the skeleton.
- 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).
Atoms are made up of subatomic particles such as the proton, electron and neutron. Two or more atoms combine to form a molecule, such as the water molecules, proteins, and sugars found in living things. Molecules are the chemical building blocks of all body structures. A cell is the smallest independently functioning unit of a living organism.

The skeletal system includes all of the bones, cartilages and ligaments of the body that support and give shape to the body and body structures. For adults, there are 206 bones in the skeleton. Younger individuals have higher numbers of bones because some bones fuse together during childhood and adolescence to form an adult bone.
