PPT-4.1 Joints and Muscles

What would life be like without Joints Move a joint that you use often How do different joints move Essential Question 1 What role do joints play in the human body Joints are the places where two bones meet and allow movement amp flexibility and provides support to the human skeleton. The overall tendency is to shrink and this can cause cracking at an early age Irregular cracks are unsightly and difficult to maintain but gen erally do not affect the integrity of concrete Joints are simply preplanned cracks Joints in concrete slab Muscular Physics.

The Skeletal System- Part 4. JOINTS. aka Articulations. 2 Functions:. Hold Bones Together. Allows otherwise rigid skeleton to have some flexibility. Classification of Joints. . 2.BONES. The framework of the human body is composed of 206 bones and it forms the skeletal system. This system has 5 major functions. The skeleton gives shape and support to your body. Bones protect your internal organs. Major muscles are attached to bone and help them move. Blood cells are formed in the center of the soft tissue called marrow. Finally, major quantities of calcium and phosphorous compound, which make bones hard, are stored in the skeleton.. Types of pipe materials. Metallic Pipes. : . Unlined metallic pipes . – . Cast Iron(C.I). Galvanized Iron(G.I). Mild Steel(M.S). Ductile steel (D.I). Metallic pipes lined with cement mortar or epoxy lining. What are joints?.
