EXPERIMENT 6: VIRTUAL MODEL- THE MUSCULAR SYSTEM (UPPER BODY)

The previous experiment investigated the physiological role of the muscular system. In this experiment, you will use the virtual model to learn about the anatomical placement of each muscle. Through this process, you will obtain a more detailed under- standing of the muscular attachments and coordinated movements that allow humans to move. Further, you will understand how muscles contract for postural control or force applications.

PROCEDURE

1. Open the virtual model website linked in the materials section.

2. Familiarize yourself with the virtual model. Navigate the model by using the commands below:

a. Select the body system of interest from the box in the upper left-hand corner of the model. Note that

some body systems may have multiple options for viewing (e.g., for the nervous system, you can select

either the general anatomy or the brain).

b. Hover your cursor over different areas on the model to display labeled terms.

c. Click on any component of the body to view a description of its function.

d. In the bottom right-hand corner of the model you will see a two magnifying glasses with a “+” at the bot-

tom and a “-“ at the top. Click on these buttons to zoom in and out of the virtual model.

e. When zoomed in, use your cursor to click and drag the virtual model to the area of interest.

g. Use the “Views” pop-up menu to change the orientation of the virtual model. These options may include

the anterior view, posterior view, lateral view, superior view, and inferior view of the virtual model. Note

that not all options may be available for each system.

h. Some systems may have multiple layers to explore. Click on “Layers” pop-up menu to access a deeper

layer of the system of interest if available for the system being observed.

3. After you are comfortable with the Virtual Model interface, se-

lect the Muscle option. Then, select General Anatomy.

4. Click through the upper body muscles, including the muscles of

the abdomen, back, head, neck, thorax, and upper limbs (Fig-

ure 7).

Figure 7: Work your way through the upper body muscles to better understand the anatomical placement and coordination of each muscle group.

Note: Zoom in on the muscles to reveal all elements.

Some muscles are only visible when you zoom in.

Remember that you will need to reorient the virtual

model to observe all of the muscles.

5. Hover the cursor over different muscles to view the name. Click

on each muscle to view a description of it.

Hint: Review the post-lab questions as you work

through the muscles.

6. Click the “Layers” button to view the in-depth layer of muscles.

Note that the in-depth layer can only be seen when the virtual model is in the anterior view.

7. As you move through the model, take a screenshot or use your cell phone to take a picture of the muscles listed below. Sub-

mit these images to your instructor along with your post-lab questions.

a. Latissimus Dorsi Muscle

b. Greater Pectoral Muscle

c. Brachial Muscle

Hint: Be sure to hover your mouse over the muscle to reveal its label in the image.

8. Answer the post-lab questions when you have finished exploring the upper body.
