Skeletal System

1. Skeletal System

2. The human skeleton consists of…well, tradition says 206, but who really cares? More importantly is what the skeleton does. • It provides support for our body. • Work together with muscular and nervous system to coordinate movement. • They provide protection for vital organssuch as the brain, heart, and lungs. • Blood is made inside the bonesin the marrow. Bones are living. They will bleed when cut and mend themselves when injured. • The final function of the skeleton is to provide a reservoir of minerals(calcium, phosphates, potassium, and many other trace elements), which the body can call upon to replenish depleted levels. • (Show Brain Pop Skeletal System)

4. Types of Joints • Hinge joints like those found in the knee and elbow allow the skeleton to extend or contract. • Pivot joints like those found at the top of the spine allow you to look from side to side. • Ball and socket joints like those found in the shoulders and hips allow you to rotate your arm and hip (to a lesser degree) 360 degrees. • Gliding joints are found in the wrist and between the vertebrae • The skeleton system functions together with the muscular system and the nervous system to provide support and coordinate our movements. • Show Brain POP Joints

5. Bones are attached to each other with fibrous strands called ligaments.Many sports injuries are related to torn or stretched ligaments. Ligaments should not be confused with tendons.Tendons are fibrous tissues that connect muscles to bones. Tendon injuries are also common in active people. Cartilageis a smooth, (hard) plastic-like material that is found between major joints like the knee and vertebrae. Cartilage acts both as a shock absorber between joints and as a smooth surface that allows the joints to move with less friction.

Cartilage is a smooth, plastic-like substances found between major joints in the body like the knee and between the vertebrae. Cartilage protects bones by absorbing shock and by reducing friction between bones (bones rubbing against each other.) Tendons attach muscles to bone.

8. Bell Ringers & Closing Questions What are the five major functions of the skeletal system? Provides the body with support. Works with muscular system to aid in movement. Protects important organs like the brain, lungs, and heart. Blood is made in the bone marrow. Stores important minerals like calcium.

9. Bell Ringers & Closing Questions hinge • The knee and elbow are examples of ____________ joints. • 2. The joint where the femur joins the hip and where the humerus joins the shoulder are examples of _________________ joints. • 3. What type of joint is located at the top of the spinal column where it meets the skull? • 4. A _____________________ connects a muscle to a bone. • 5. A _____________________ connects one bone to another bone. • 6. ________________________ is a smooth, hard plastic-like material found between the major joints of the body that keeps bones from rubbing against each other and absorbs shock.
