Warm up #1

Articular cartilage is the cartilage present where bones articulate with other bones.

Brainstorm: what do you think the term 'articulate' means in anatomy?

Warm-Up #2

a. What do you know about the skull?

b. What do you want to know about it?

First, check out this simulation: https://www.visual-science.com/projects/skull/intaractive-app/

Which of the following perspectives of the skull are we able to see with this simulation?

Skull: Lateral Perspective

Use the simulation to identify, label (in blue text) and color the bones provided on the key above the diagram.

In addition to labeling and coloring the bones in the diagram, use the textbook to identify and label (in red text) the following structures:

• squamous suture

• coronal suture

• lambdoid suture

• external acoustic meatus

• styloid process

• mastoid process

• mandibular condyle

(Notice that there are many more landmarks provided on the website. You are only responsible for knowing the locations of the landmarks listed above!)

Skull: Anterior Perspective

Use the simulation above to identify, label (in blue text), and color the bones provided on the key above the diagram.

In addition to labeling and coloring the bones in the diagram, use the textbook to identify and label (in red text) the following structures:

• supraorbital foramen

• mental foramen

• inforaorbital foramen

• orbital surface of the sphenoid

• greater wing of the sphenoid

(Notice that there are many more landmarks provided on the website. You are only responsible for knowing the locations of the landmarks listed above!)

Skull: Inferior Perspective

Use the simulation above to identify, label (in blue text), and color the bones provided on the key above the diagram.

In addition to labeling and coloring the bones in the diagram, use the textbook to identify and label (in red text):

• transverse palatine suture

• mastoid process

• foramen magnum

• occipital condyle

• zygomatic arch

• anterior palatine foramen

• median palatine suture

• styloid process

(Notice that there are many more landmarks provided on the website. You are only responsible for knowing the locations of the landmarks listed above!)

Look back at your diagrams and identify the following general structures. Match the structure with its possible definition.

Match the following foramina (foramen) of the skull with the bone that they are located in.

Which of the following bones contribute to the formation of the orbit of the eye?

There is one suture not pictured in the diagrams: The Sagittal suture.

Think back to your anatomical terminology lessons. Which of the following might best describe the location of the sagittal suture, and from which perspective do you think we would best be able to see it?

There are four prominent sutures of the adult skull. Identify the bones that join to form these sutures.

One of the bones you identified today, colored in yellow in the diagram below, is particularly hard to see from the lateral, inferior, and anterior perspectives. It is best seen from the superior perspective if a transverse cut is made through the skull:

Which bone is this?

Six of the bones of the skull are unpaired. This means that there is only one of them.

Which of the following skull bones are unpaired?

Which bones of the skull would be considered parts of the cranium rather than the face?

Match the bones with their description

Listen to the radiolab segment below. It takes about 20 minutes (yes, listen to the whole thing!). As you listen, look at the picture of the skull that the segment is about.

When you are done listening write a 4-5 sentence description of the Radiolab segment.

What is one interesting thing you learned during the radiolab segment?

What is one question you still have about the content in the radiolab segment?

The pictures below depict/display a condition called sagittal craniosynostosis

Using the medical terminology website:

• break this term up into its components and

• come up with a defintion for this condition.

(I WILL know if you use the website or not, and you won't get credit if you don't use it!)

Finally, watch the video below about Sagittal Craniosynostosis surgery.

a. Compare and contrast the two surgery options.

b. A child is diagnosed with sagittal craniosyntosis at two months old. Which procedure would you recommend and why?
