They display varying amounts of mobility. - The synovial joint with the highest degree of movement is called a ball-and-socket joint.

Complete each sentence by dragging the proper word or phrase into the appropriate position to describe the typical anatomy of a synovial joint. 1. The oppossing surfaces of bones that are connected via synovial joints are covered with a thin layer of _______________. 2. Between the articular surfaces, a thin cavity is filled with _______________, which acts to lubricate the joint surface and nourish the tissues of the internal joint surface. 3. The __________________ maintains the boundary of the joint and contains the synovial fluid. 4. The outermost layer of the joint capsule is the _______________ capsule, which is continuous with the periosteum and provides support to the joint. 5. The deeper portion of the capsule is the ___________________, which contains cells that synthesize the synovial fluid. 5. An example of fibrocartilage that provides additional padding and stability to the joint is the ______________ of the knee

- The oppossing surfaces of bones that are connected via synovial joints are covered with a thin layer of articular cartilage. - Between the articular surfaces, a thin cavity is filled with synovial fluid, which acts to lubricate the joint surface and nourish the tissues of the internal joint surface. - The joint capsule maintains the boundary of the joint and contains the synovial fluid. - The outermost layer of the joint capsule is the fibrous capsule, which is continuous with the periosteum and provides support to the joint. - The deeper portion of the capsule is the synovial membrane, which contains cells that synthesize the synovial fluid. - An example of fibrocartilage that provides additional padding and stability to the joint is the meniscus of the knee.

Complete each sentence by dragging the proper word or phrase into the appropriate position. Then place each sentence in order of mobility beginning with the least mobile. 1. When two bones join together and fuse so that no visible separation occurs, it is referred to as a(n) ____________ , or bony joint. 2. Bones that join together and are held in place with threads of collagen, form a joint that is called a(n) ____________ . 3. The most complex joints are called ____________ joints. They display varying amounts of mobility. 4. Bones joined together with cartilage between the ends of the bones, form a joint called a(n) ____________ . 1. amphiarthrosis 2. suture 3. gomphosis 4. synarthrosis 5. synostosis 6. synovial

Drag each term into the appropriate position to identify several examples of joint movement. 1. Usually returns a body part to zero position 2. Usually decreases a joint angle 3. Movement beyond the joint's zero position 4. Movement in the frontal plane back toward the midline 5. Movement in the frontal plane away from the midline 6. Raises a body part vertically in the frontal plane 7. Lowers a body part vertically in the frontal plane 1. pronation 2. cicumduciton 3. abduction 4. elevation 5. inversion 6. extension 7. depression 8. adduction 9. hyperextension 10. supination

Usually returns a body part to zero position - extension Usually decreases a joint angle - flexion Movement beyond the joint's zero position - hyperextension Movement in the frontal plane back toward the midline - adduction Movement in the frontal plane away from the midline - abduction Raises a body part vertically in the frontal plane - elevation Lowers a body part vertically in the frontal plane

Classify the following image into the types of joints they represent. 1. suture 2. gomphosis 3. syndesmosis

gomphosis

Drag each description into the appropriate position to identify the three different types of fibrous joints. 1. gomphosis 2. syndesmosis 3. suture 1. an example of this joint is the attachment of a tooth to its socket 2. examples of this joint include the coronal, sagittal, and lambdoid 3. an example of this joint is the joint between the shafts of the radius and ulna 4. this joint lies between the temporal and parietal bones 5. this term refers to the joint's similarity to a nail hammered into wood 6. this joint is held firmly in place by a fibrous periodontal ligament 7. this is a joint whose fibers are longer and the attached bones are more movable 8. this is the joint that binds the distal ends of the tibia and fibula together 9. this joint closely binds the bones to the skull to each other 10. this is a joint in which two bones are bound by longer collagenous fibers

gomphosis - an example of this joint is the attachment of a tooth to its socket - this term refers to the joint's similarity to a nail hammered into wood - this term refers to the joint's similarity to a nail hammered into wood syndesmosis - this is a joint whose fibers are longer and the attached bones are more movable - this is a joint in which two bones are bound by longer collagenous fibers - this is the joint that binds the distal ends of the tibia and fibula together - an example of this joint is the joint between the shafts of the radius and ulna suture - this joint closely binds the bones to the skull to each other - examples of this joint include the coronal, sagittal, and lambdoid - this joint lies between the temporal and parietal bones
