TOPIC AND TEXT REFERENCE: SCALP AND INTERIOR OF SKULL PP. 156-161

LEARNING OBJECTIVES:

Identify the layers of the scalp.

Observe the suture lines of the skull.

Identify the meningeal layers.

Identify the subarachnoid space and understand the pathway of the cerebrospinal fluid.


SPECIAL INSTRUCTIONS FOR LAB TODAY:

Pg. 156: The scalp incisions have already been made for you.

Pg. 158: The calvaria have already been removed on the even numbered tables.

Pg. 158: We will not be doing the removal of wedge of occipital bone.

Pg. 159: Since we are not removing the wedge of occipital bone, the transverse sinus will not be visible until the brain is removed.

Pg. 161: Today's lab finishes right before the removal of the brain. However if you wish to go ahead and remove the brain, ask a faculty member to assist you.

CLINICAL CORRELATIONS AND EXERCISES:

1. Where is the "dangerous area" in the scalp? Why is it called that?

2. What artery is often the cause of an epidural hematoma?

3. How does a subdural hematoma differ from an epidural hematoma?

4. Where does CSF originate and how is it recycled?

KEY STRUCTURES:
You should be able to identify in a cadaver all the structures listed under key words unless they have an asterisk.
