Anatomy & Physiology A
4.2 Balloon Skull Lab
Introduction:
In this lab, you will be performing the work of a superficial anatomist. Their work deals with studying anatomy that can be viewed by sight, without needing any dissection of an organism. Superficial anatomy focuses on the form and proportions of surface landmarks of the human body.
Requirements:
Demonstrate proper use of anatomical terminology by labeling the superficial anatomy of an adult and fetal skull and recording your observations.
Materials And Supports You Need:
●
1 Balloon: Preferably a light color so that your writing can be observed
●
Sharpie marker for labeling on your balloons (do not use a pen)
●
Digital Camera or a phone for uploading images of your work
●
A friend/family member to hold your balloon skull while photo-documenting
Pre-Lab Questions
1.
The axial skeleton is divided into what three parts? Skull, vertebral column, and thoracic cage.
2.
The skull is formed by what two sets of bones? Facial bones and the cranium.

Procedure:
*There are multi-steps to complete this lab. You must read through all Procedures before beginning
. You will want to give yourself enough time to label the surface anatomy on your balloon and take pictures without the balloon deflating. You will also want to think about the relative size differences required between an adult and fetal skull in advance.
1.
ADULT SKULL:
A.
Blow up your first balloon and tie off the end. Because adult skulls tend to be taller in height, the end will become the inferior portion of the skull, where the neck is.
B.
Referencing your lesson and your practice activities, first draw the eye and nose sockets. This will help you identify the anterior side as you continue. We will not be drawing every one of the facial bones that make up the sockets. i.
Draw the sutures that enclose the Frontal bone, and label this area F.
ii.
Draw the sutures that enclose the Maxillary bones, and label these areas MR and ML (For Maxilla Right and Maxilla Left). Be sure to maintain anatomical position by appropriately labeling each bone's left and right sides
. At this time, you should draw the teeth of the superior jaw.
iii.
Draw the sutures that enclose the Mandible bone, and label this area Man. At this time, you should draw the teeth of the inferior jaw.
iv.
Draw the sutures that enclose the Zygomatic bones, and label these areas ZR and ZL.
v.
Draw the sutures that enclose the Sphenoid bone, and label both of the superficial portions that can be seen on the exterior of the skull as Z. (Remember, this is not a paired bone, so there is no “right” and “left” bone).
vi.
Draw the sutures that enclose the Parietal bones, and label these areas PR and PL.
vii.
Draw the sutures that enclose the Temporal bones, and label these areas TR and TL.
