Summary Introduction
Introduction:
Joints are the part of the body that helps in movement. They are formed by the articulation of the surfaces of two or more bones. They consist of cartilage, synovial membrane, ligaments, tendons, synovial fluids, bursa and meniscus. Based on these components the joints are classified into several types such as some joints are articulated with hyaline cartilage whereas, some are articulating with fibrocartilage.

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.
A bursa ________.a. surrounds a tendon at the point where the tendon crosses a jointb. secretes the lubricating fluid for a synovial jointc. prevents friction between skin and bone, or a muscle tendon and boned. is the strong band of connective tissue that holds bones together at a synovial joint

- Watch this video (http://openstaxcollege.org/l/synjoints) to see an animation of synovial joints in action. Synovial joints are places where bones articulate with each other inside of a joint cavity. The different types of synovial joints are the ball-and-socket joint (shoulder joint), hinge joint (knee), pivot joint (atlantoaxial joint, between C1 and C2 vertebrae of the neck), condyloid joint (radiocarpal joint of the wrist), saddle joint (first carpometacarpal joint, between the trapezium carpal bone and the first metacarpal bone, at the base of the thumb), and plane joint (facet joints of vertebral column, between superior and inferior articular processes).
