A study of the human anatomy skeletal system

The tibia and fibula form the ankle joint with the talus, one of the seven tarsal bones in the foot. The amount of red bone marrow drops off at the end of puberty, replaced by yellow bone marrow. Also common is scoliosisa side-to-side curve in the back or spine, often creating a pronounced "C" or "S" shape when viewed on an x-ray of the spine.

Many tiny cells called osteocytes live in small spaces in the matrix and help to maintain the strength and integrity of the compact bone. For more details on clavicle, visit: Sacrum - 1 vertebra Coccyx tailbone - 1 vertebra With the exception of the singular sacrum and coccyx, each vertebra is named for the first letter of its region and its position along the superior-inferior axis.

The carpal bones of the wrist and the tarsal bones of the foot are examples of short bones. In this article the parts of the skeleton are described in terms of their sharing in these functions.

These are the sites of production of new blood cells. It consists of Skull, vertebral column and thoracic cage. Clavicle is a modified long bone and is subcutaneous throughout its position. Such a covering is provided by the bony thoracic basket, or rib cagewhich forms the skeleton of the wall of the chest, or thorax.

Compact bone is made of a matrix of hard mineral salts reinforced with tough collagen fibers. These muscles provide motor power for producing movements of body parts. Long bones grow more than the other classes of bone throughout childhood and so are responsible for the bulk of our height as adults.

The skeleton of each upper limb consists of 30 bones. Skull A variety of gross morphological traits of the human skull demonstrate sexual dimorphism, such as the median nuchal linemastoid processessupraorbital marginsupraorbital ridgeand the chin. Ileum, Ischium and Pubis.

Looking at a bone in cross section, there are several distinct layered regions that make up a bone. Bones of the human skeleton in all parts of body provide attachment to the muscles.

How to Study the Bones in the Human Skeleton

Red bone marrow is found in the hollow space inside of bones known as the medullary cavity. These joints provide a small amount of flexibility in the joint due to the gel-like consistency of cartilage.

The tibia and fibula form the ankle joint with the talus, one of the seven tarsal bones in the foot. Blood vessels present in the periosteum provide energy to the cells on the surface of the bone and penetrate into the bone itself to nourish the cells inside of the bone. Axial Skeleton Appendicular Skeleton: The symptoms of arthritis will vary differently between types of arthritis.

In general, female skeletal elements tend to be smaller and less robust than corresponding male elements within a given population. See Article History Human skeletal system, the internal skeleton that serves as a framework for the body. The outside of a bone is covered in a thin layer of dense irregular connective tissue called the periosteum.

The Axial Skeleton The axial skeleton includes 80 of the bones of the body. It possesses three important processes: Cartilage is also a form of connective tissue but is not as tough and rigid as bone. Human Skeleton Human skeleton is composed of three main components; Bones, Associated cartilages and Joints.

The tarsals are a group of seven small bones that form the posterior end of the foot and heel. Almost every skeletal muscle works by pulling two or more bones either closer together or further apart.

The vertebral column, corresponding to the notochord in lower organisms, is the main support of the trunk. The human skeleton, like that of other vertebratesconsists of two principal subdivisions, each with origins distinct from the others and each presenting certain individual features.

Sexual dimorphism in the long bones is commonly characterized by morphometric or gross morphological analyses.

Deep to the compact bone layer is a region of spongy bone where the bone tissue grows in thin columns called trabeculae with spaces for red bone marrow in between. This site was designed for students of anatomy and physiology. It contains textbook resources, such as chapter review guides, homework sets, tutorials, and printable images.

The human skeleton includes bones, over half of which are in the hands and feet alone. The study of bones can focus on their names in different parts of the body, or on the physical properties of bones, such as their growth and repair, and on the function of bone marrow in blood-cell formation.
