You must install Adobe Shockwave Player and Quicktime onto your computer in order to view these videos and tutorials (they are available for free online & section will focus on three joints in the human body: the shoulder, hip, and knee joint. These are the most complex joints in the body and as such, provide a wide range of movement, and are most commonly injured. All background information on these joints is included in the linked videos below. You will need to accomplish some independent research to investigate common injuries at these joints.Assignment overview: In this SLP, you will prepare a presentation, consisting of 10-11 slides, in which you provide your audience with information on the following areas:Slides 1-2: To introduce the anatomy of the shoulder, knee, and hip joints define the following terms:Prime mover, antagonistSynergistLigamentTendonFlexion, extension, abduction, adduction, medial and lateral rotationOrigin, Insertion, and actionBall and socket jointHinge jointSlides 3-8: Label the following:Shoulder (Slide 3 and 4) Label and describe in the Notes SectionsGlenoid labrumrotator cuff muscles and ligamentsthe major muscles that cross the shoulder to move the humerus: deltoid, pectoralis major, latissimus dorsi, and trapeziusIn the notes sections: define the prime movers, and synergists and the actions they accomplish at the shoulder jointHip (Slide 5 and 6) Label and describe in the Notes SectionsFlexors of the hip (prime movers and synergists)Extensors (prime mover and synergist)Abduction (include gluteus maximus and minimus, and tensor fascia latae) and adduction (include adductor magnus, gracilis, and pectineus)Acetabular labrum of the internal capsuleKnee (Slide 7 and 8)quadriceps and hamstringsthe ligaments ACL, MCL, PCL, LCL, (LABEL WITH THE FULL NAMES)the menisciThe muscles that cross the knee joint: the quadriceps (label all four) and the hamstrings (label all three)Notes section: Provide the movements accomplished by the quadriceps and hamstrings as they act on the lower legSlides 9-10: Label the tendons, ligaments, and/or internal joint structures that are commonly damaged and what motions cause that damage at the shoulder, knee, and hip joints.Provide examples of therapies used to treat those injuries.Slide 11: ReferencesDon’t forget—place your descriptive text in the speaker notes of each slide. This is where you should be able to describe the movements, arrangement, and common injuries as outlined in the requirements above. Use sufficient depth and breadth to demonstrate your understanding of the important muscles, structures, and movements accomplished in each joint.Resources and Background Information:Shoulder joint. Follow this video link to an overview of the arrangement of the muscles of the glenohumoral (shoulder) joint. Proceed to the description of the movements accomplished by the shoulder joint. Next follow each link to the videos that describe the muscles of the shoulder: pectoralis major, deltoidand latissimus dorsi as (prime movers), and the muscles of the rotator cuff. Be sure to view these videos that describes the function and structure of these synergists in the shoulder joint.Reference images can be found in your Background page or by searching “shoulder joint image” on the internet.Now review the general structure and movements produced at the coxal or hip joint as illustrated in this video link. Follow this link to the muscles of hip to view the muscles that move the femur or upper thigh.Finally, view these links to observe the movements accomplished here. Use the following linked videos to learn specifics about how the quadriceps and hamstrings move the lower leg at the knee. Additional images are available in your Background section.
