Synovial Joints

BIOS251OL, Week 7 Lab

Name:

OL Lab 7: Joints

Learning Objectives:

· Identify the structures of the synovial joints and its related functions.

· Identify the structural and functional classification.

· Identify the different types of movements produced by the synovial joints.

:

For this part of the lab you will use Anatomy TV to explore the synovial joints in skeletal system and correlate the anatomical structures to its functions. Please read the instructions before you begin.

Instructions:

1. Use the link below to log into Anatomy TV via Chamberlain Library.

https://library.chamberlain.edu/az.php?q=

.

2. Select Anatomy TV under popular databases to access the site.

3. Select the ‘skeletal system’ tile:

4. From the skeletal system module, select the interactive learning module

on the left hand side of the page.

Analysis of Joints
:

5. Select the interactive learning: Joints

Select the ‘synovial joints’ interactive circled in red.

6. On the image identify and select a one anatomical structure at a time.

The selected region will appear highlighted.

7. Use the controls at the bottom of the page as required. Follow the recommendations

provided for each structure.

8. Take a screen shot of the image or save the image using the download icon on

the right hand side tab.

9. Create a word document titled “lastname_Lab 7”. Import the image into the document. Use the functions ‘Insert’ and ‘tool’ (shapes) on word to label the images.

10

. In a complete sentence, write the functional role of the selected anatomical structure

under the image.

11. Save the file before you proceed to the next structure.

12. Follow these steps to analyze all the structures listed below.

a. Femur

b. Tibial collateral ligament

c. Joint capsule

d. Supratellar bursa

e. Tibia

f. Medial meniscus

Use the layer controls to remove/add layers ending on layer 10 and rotation controls to rotate the model to frame 9 for the following structures.

g. Synovial fluid

h. Patella

i. Patellar ligament

j. Articular hyaline cartilage

k. Fat pad

Part B: Read the case study. In your own words and in complete sentences answer the questions
:

John, a 75-year-old man, was diagnosed with osteoarthritis in his knee five years ago. Recently his condition worsened and so decided to see a doctor. John’s doctor ordered a radiograph imaging in order to visualize his knee joint.

a. What is osteoarthritis? What symptoms will John experience? (3 points)

b. What type of joint is the knee? (1 point)

c. What is the meniscus in the knee and state its function? (2 points)

d. What is the role of articular cartilage in a synovial joint? (2 points)

e. What is the role of synovial fluid? (2 points)

Part C: Movements of Synovial Joints
:
Critical thinking Questions:

In your own words and in complete sentences answer the following questions
:

a. What are the movements involved when you shrug your shoulders? What is the functional classification of the shoulder joint?(3 points)

b. Identify the type of movement at the hip and shoulder joints when you perform jumping jacks? ( 2 points)

c. Why do individuals with overpronation might exhibit uneven wear on the inside of the midsole? ( 2 points)

d. What are the joints and the movements involved when kicking a soccer ball? (3 points)
