1.What types of joint movement (hip flexion, extension, etc.) occur during walking?

Help PLZ     1 Synovial joints have several features that distinguish them. Some of these features are a joint space, hyaline cartilage covering the articular surface, and synovial membranes that secrete synovial fluid. What is the function of synovial fluid? A. decrease friction between joint surfaces and provide nourishment to articular cartilage B. temporary fluid that occurs during overuse to limit injury C. increase stability of the joint by filling the joint space D. increase friction to slow and control joint movement 1B Positioning of the lacunae within bone tissue helps classify the type of bone. Please complete the comparison: Osteon is to compact bone as ____________ is to spongy bone.   A. periostium B. canaliculli C. central canal D. trabeculae 1d. Bending your head back to look up at the ceiling is an example of ________. A. circumduction B. rotation C. extension       D. flexion

part 1. Sarcolemma - a delicate cell membrane of the muscle cell 2. Nucleus - a rounded structure beneath the sarcoplasm 3. Sarcoplasm - a cytoplasm enclosed by the sarcolemma 4. Cross-striation - heavily shaded thin bands and light bands across the cell OBSERVATIONS: 1. What is the shape of the skeletal muscle fibers? 2. Draw and label the parts of the skeletal muscle fibers.

19. The temporomandibular joint is the only mobile joint between skull bones. True or False     27. Moderate exercise improves the health of joints by increasing the flow of synovial fluid in and out of the articular cartilage. True or False

6. There are 3 main types of joints. Complete the table, to show any similarities & differences in the structure and key characteristics between them. Make sure you also include an example of each type of joint and a simple diagram of each. Type of Joint 1. 2. 3. Anatomy of the joint Degrees of movement Diagram of basic joint Example

We are focusing mainly on synovial joints, because this is the main type of joint that allows you to move your body. Using the diagram below, match the synovial joint structure with its description: -Periosteum E F A G D H- F V [ Choose ] A Friction-reducing hyaline cartilage that covers bone surfaces B Cavity filled with lubricating, nourishing, and shock-absorbing fluid Bands of dense regular connective tissue that connect muscle to bone and help stabilize joints Fluid-filled pocket that reduces friction between joint structures Bands of dense regular connective tissue that connect bones Cushions of fibrous cartilage that help guide joint movement E Protective outer wrapping made of dense irregular connective tissue One of the four body membranes; produces synovial fluid F G [ Choose ] [ Choose ]

1. In the human body...bones: lever, and the 5 = is the force. of a lever. The joint is the What is the most common lever system in the human body-2 1st? 2nd2 3rd? of a U
