Skeletal System

The adult humanskeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage thatconnects them. The skeletal system performs vital functions — support, movement, protection, blood cellproduction, calcium storage and endocrine regulation — thatenable us tosurvive.

The skeletons of adult males and females have some variation, primarily to accommodate childbirth. The female pelvis is flatter, more rounded and proportionally larger. A male's pelvis is about 90 degrees or less of angle, whereas a female's is 100 degrees or more.

While they become brittle when outside of the body, bones are very much alive inside the body, being fed by a network of blood vessels from the circulatory system and nerves from the nervous system.

A typical bone has a dense and tough outer layer. Next is a layer of spongy bone, which lighter and slightly flexible. In the middle of some bones is jelly- like bone marrow, where new cells are constantly being produced forblood.

Teeth are considered partof the skeletal system but they are not counted as bones. Teeth are madeof dentin and enamel, which is strongest substancein your body. Teethalso playa key role in the digestive system.

The skeletal system has two distinctive parts: the axial skeleton and the appendicular skeleton.

The axial skeleton, with a total of 80 bones, consists of the vertebral column, the rib cage and the skull. Theaxial skeleton transmits the weight from the head, the trunk and the upper extremities downto the lower extremities at the hip joints, which help humans maintainour uprightposture.

The appendicular skeleton has a total of 126 bones, and is formed by thepectoral girdles, the upper limbs, the pelvic girdle and thelower limbs. Their functions are to make walking, running and other movement possible and to protect the major organs responsible for digestion, excretion and reproduction.

1. What do you think is the main function of the human skeleton?

©KeslerScience.com

There are 5 main functions for the human skeleton.

• Support and protect• Movement• Storage• Blood• Homeostasis1. In your own words, explain how you

think each of these relate to the skeletal system

©KeslerScience.com

1. Support and protect – the skeleton allows the body to be supportedand protects our internal organs from damage.

2. Movement – the skeleton works with the muscular system to allow for movement.

3. Storage – the interior of the bone can store calcium, phosphorus, and fatty acids

4. Blood – Inside the marrow of the bone stem cells canbe turned into red blood cellsas well as many other types of cells.

5. Homeostasis – bones are able to absorb or release calcium into the blood to maintain a stable environment in the body.

Each group will use the diagram to answer the questions on the cards.

Use the skeletal diagram to answer the following questions.

The axial skeleton consists of the 80 bones along the central axis of the human body.

The appendicular skeleton is composed of 126 bones in the human body involved in locomotion (lower limbs) of the axial skeleton and manipulation of objects in the environment (upper limbs).

1. On your lab sheet determine which bones are axial and which ones are appendicular. Label them.

2. Beside each of the bone names also list which part of the body the bone belongs to. (ex. Head, shoulder, etc.)
