Skeletal system

OL Lab 6: Skeletal system

Learning Objectives:

· Identify the two divisions of the skeleton.

· Identify the bony features found on bones and identify their functions

In this lab, you will use Anatomy TV to explore the skeletal system and correlate the anatomical structures to its functions. Please read the instructions before you begin with the lab.

Instructions:

A. Preliminary steps:

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.

B. Laboratory Steps

Part 1: Analysis of the Skull

1.1 Select the interactive learning: Skull:

Select the interactives circled in red.

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

The region selected will appear highlighted.

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

provided for each structure.

1.4- Take a screen shot of the image or save the image using the download icon on

the right hand side tab.

1.5- Create a word document titled “lastname_Lab 6”. Import the image into the document. Use

the functions ‘Insert’ and ‘tool’ (shapes) on word to label the images.

1.6- In complete sentence write the functional role of the selected anatomical structure under the image.

1.7- Save the file before you proceed to the next structure.

1.8- Follow these steps to analyze all the structures listed below.

e. Sternum: manubrium

f. Sternum: body

g. Sternum: xiphoid process

h. Typical rib (6th): shaft

i. 1st rib: head

Part 3: Analysis of bones of the Upper Limb

Select the interactive learning: Bones of the Upper Limb

Select the interactives circled in red.

Repeat steps 1.2 to 1.7 to identify and select the following structures:

a. Scapula: subscapular fossa

b. Scapula: coracoid process

c. Humerus: head

d. Humerus: trochlea

e. Humerus: lesser tubercle

f. Ulna: coronoid process

Use the rotation controls to rotate the model to frame 16 for the following structures.

g. Scapula: infraspinous fossa

h. Scapula: inferior angle

i. Scapula: spine

j. Humerus: shaft

k. Humerus: deltoid tuberosity

l. Ulna: olecranon

m. Radius: head

Bones of the forearm:

a. Radius

b. Ulna

c. Capitate

d. 1st metacarpal

e. Middle phalanx of 4th finger

Use the layer controls to remove/add layers ending on layer 2 and rotation controls to rotate the model to frame 19 for the following structures

f. Metacarpal: shaft

g. Middle phalanx: base

h. Humerus: medial epicondyle

i. Radius: tuberosity
