Human Anatomy & Physiology © ACCESS Virtual Learning 2023 Name: Date: School: Facilitator: 6.04 Types of Joints (43 Points) Part A: Joints by Function Identify the following as A, B, or C. (1 point each) A. Synarthrosis B. Diarthrosis C. Amphiarthrosis 1. Joints between vertebra: c 2. Knee joint: b 3. Shoulder joint: b 4. Suture lines between the bones of the skull: a 5. Describe the difference between synarthrosis, diarthrosis, and amphiarthrosis joint types: Write your answer below: Synarthrosis, diarthrosis, and amphiarthrosis are different types of joints in the body. Synarthrosis joints, like the sutures in the skull, don't move at all. They provide stability and protection. Diarthrosis joints, such as the knee and shoulder joints, are super flexible and allow for a wide range of motion. Amphiarthrosis joints, like the ones between the vertebrae, have some movement, but not as much as diarthrosis joints. They give a mix of stability and limited movement. So, that's the scoop on these joint types. Part B: Synovial Joints Answer the following (1 point each blank) 1. Why are synovial joints referred to as freely moveable joints? Synovial joints are referred to as freely movable joints because they allow for a wide range of motion. The term "freely movable" means that these joints have the ability to move in various directions, such as bending, extending, rotating, and more. The presence of synovial fluid within these joints helps reduce friction and allows for smooth movement. So, synovial joints give us the freedom to move our bodies in different ways!

Create a table of information about synovial joints: Type of Joint Movement Type Example extension straightening of a joint that increases the angle between the bones stretching your arm straight flexion bending of a joint that decreases the angle between the bones bringing your knee towards your chest circumduction circular movement of a joint combining abduction adduction flexion and extension moving your arm in a circular motion rotation circular movement around an axis turning your head from side to side adduction movement that brings bone towards the center of the body bringing your legs together gliding flat surfaces sliding across each other sliding your hand across the table Part C: Name that Joint Identify the following synovial joints. (1 point each blank) 1. pivot joint 2. plane joint
