Chap 8 joints pgs 155 174

Read Chap 8. Review all notes & diagrams. Finish the last slide – the six types of synovial joints.

Chap 8 Joints Pgs.155-174

Learning Objectives:

Explain an articulation (joint).

Classify joints based on structure and function. Describe their characteristics.

Demonstrate common body movements.

Identify and describe the main joints of the elbow, knee, hip, and shoulder.

Explain the basis of common joint injuries such as rotator cuff injury.


Shoulder problems

Shoulder Problems

  • A patient presents will extreme pain in the shoulder area, mobility is limited, and rest/ ice have not improved the situation over time. After thorough examination, it is determined that the patient’s cartilage is badly torn. Rotator cuff surgery is required:

Review

Review

  • What is an articulation?

An articulation is also known as a _________.

What are sutures (as in the coronal suture)?


Joints

Joints

  • Weakest parts of the skeleton

  • Two functions of joints

    • Give the skeleton _________

    • Hold the skeleton __________


Classification of joints functional pg 157

Classification of Joints: Functional Pg. 157

  • Functional classification is based on the amount of ________ allowed by the joint

  • The three functional classes of joints are:

    • Synarthroses – __________

    • Amphiarthroses – ___________

    • Diarthroses – ___________


Fibrous joints pg 157

Fibrous Joints Pg.157

  • The bones are joined by _______ tissues

  • There is no joint _______

  • Most are ____________

  • There are three types:

    1. sutures (Example: seams in the skull)

    2. syndesmoses (bones connected by

    ____________) Example: ligament connecting the distal ends of the tibia and fibula

    3. gomphoses (____ -in-socket type of fibrous joint) Example: peridontal ligament


Cartilaginous joints pg 158

Cartilaginous Joints Pg.158

  • Articulating bones are united by ________

  • Lack a joint ______

  • Two types:

    1. synchondroses – bar or plate of cartilage

    (Example: immoveable joint between the

    coastal cartilage of the first rib and

    manubrium)

    2. symphyses – articular surfaces of bones covered with hyaline cartlage which in turn is fused to a __________ pad (or plate) of ______________.

    Example: intervertebral joints


Synovial joints pg 160

Synovial Joints Pg.160

Those joints in which the articulating bones are separated by a ____________ joint cavity.

All are _______ movable

Examples – all limb joints, and most joints of the body

  • All have the following:

    • a. Articular cartilage

    • b. Joint (synovial) cavity

    • c. Articular capsule

    • d. ___________ fluid

    • e. Reinforcing ____________


Friction reducing structures in synovial joints

Friction-Reducing Structures in Synovial Joints

  • _________ – flattened, fibrous sacs lined with synovial membranes and containing synovial fluid

  • Common where ligaments, muscles, skin, tendons, or bones rub together

  • ____________ – elongated bursa that wraps completely around a tendon


Review of joints thus far

Review of Joints (Thus Far)

  • See handout

  • Estimated Time of completion = 8- 10 minutes

  • Will check answers


Synovial joints movement pg 164

Synovial Joints: Movement Pg. 164

  • The two muscle attachments across a joint are:

    1. ________ – attachment to the immovable bone

    2. _________ – attachment to the movable bone


Synovial joint range of motion

Synovial Joint: Range of Motion

  • ________ – slipping movements only

  • ________ – movement in one plane

  • _______ – movement in two planes

  • _______ – movement in or around all three planes

There are also 3 general types of movements: _______, _______, and rotation


Gliding pg 163

Gliding Pg.163

One flat bone surface _______ or slips over another similar surface

Examples – intercarpal and intertarsal joints, and between the flat articular processes of the vertebrae


Angular pg 164

Angular Pg. 164

  • _______ — bending movement that decreases the angle of the joint

  • _________ — reverse of flexion; joint angle is increased

  • _________ and plantar flexion — up and down movement of the foot

  • ________ — movement away from the midline

  • ________ — movement toward the midline

  • __________ — movement describes a cone in space


Angular continued pg 164

Rotation

Rotation

  • The turning of a bone around its own long _____

  • Examples

    • Between first two vertebrae

    • Hip and shoulder joints

Partner activity

Partner Activity

  • Quickly pair with a partner.

  • Each person should complete question #10 (a – p) pg 174 now in their workbook.

  • Then demonstrate the motions (as listed under question #10 (a-p) pg 174 to their partner
