The Joints in the Human Body : 

The Joints in the Human Body The point where two or more bones meet is called a joint. Joints are classified by their structure or the way they move. The joints of the skull are known as sutures (top, left). Sutures do not have a wide range of movement. Instead, they allow for growth and very limited flexibility. Hinge joints (top, right) allow for movement in one plane. The hinge joints of the elbow and knee, for example, bend up and down. Two flat-surfaced bones that slide over one another make up a gliding joint (bottom, right). Gliding joints, such as those in the wrist and the foot, provide for limited movement. Ball-and-socket joints (bottom, left) allow for the greatest range of motion. The ball-and-socket joints of the shoulder and hip, for example, can rotate in a complete circle.

The Human Body : 

The Human Body The function of the Human Body is to provide movement, support, protection. http://training.seer.cancer.gov/module_anatomy/unit1_2_body_functions.html Facts There are 206 bones in the adult human body. The largest bones in the adult human body is the femur. There are about 300 bones in a newborn baby but they grow together to make 206 when an adult.

The Facts About Bones. : 

The Facts About Bones. One function of spongy bone is to produce red blood cells. The smooth, flexible layer of tissue covering the ends of bones is called cartilage. The hard, strong layer of bone is called compact bone. Minerals make bones strong. The human skeleton has 206 bones of various sizes and shapes.

QUIZ Directions: Number your paper to 26 and label all the major bones of the body.

Joints : 

Joints There are three types of joints Immovable Partially movable synovial Immovable – edges that tightly interlock Partially movable – allow some flexibility Synovial – most movable joints

Joints : 

Joints All bones connect by joints the joints are… Ball and socket Pivot Saddle Hinge Ellipsoid Plane

Hinge Joints : 

Hinge Joints A hinge joint allows extension and retraction of an appendage.

Ball and Socket Joints : 

Ball and Socket Joints A ball and socket joint allows for radial movement in almost any direction. They are found in the hips and shoulders.

Saddle Joints : 

Saddle Joints A saddle joint allows movement back and forth and up and down, but does not allow for rotation like a ball and socket joint.

Ellipsoid Joints : 

Ellipsoid Joints Ellipsoid joints are similar to a ball and socket joint. They allow the same type of movement to a lesser magnitude. The wrist is an ellipsoid joint.

Pivot Joints : 

Pivot Joints Pivot joints allow rotation around an axis. The neck and forearms have pivot joints. In the neck the occipital bone spins over the top of the axis. In the forearms the radius and ulna twist around each other.

Gliding Joints & Plane Joints : 

Gliding Joints & Plane Joints In a gliding or plane joint bones slide past each other. Metacarpal and metatarsal joints are gliding joints
