Lab 12: Skull

PURPOSE:
To examine the structure of the human skull and to identify the bone and major features of the skull.

LEARNING OBJECTIVES:
1. Distinguish between the cranium and the facial skeleton
2. Locate and name the bones of the skull and their major features
3. Locate and name the major sutures of the cranium
4. Locate and name the major sinuses of the skull

PROCEDURE:
1. Review Cpt 5 pages 140-141, and the Skeleton Outline page

2. Print out images 12.1-12.4 (Below), paste into your NoteBook and Label

3. Examine the cranial bones of the skull specimens, both articulated and disarticulated and locate the following parts. Palpate the corresponding bones in your own skeleton, if possible: Frontal bone, supraorbital notch, frontal sinus; Parietal bones, sagittal suture, coronal suture; Occipital bone, lamboidal suture, foramen magnum, occipital condyles; Temporal bones, squamosal suture, external auditory meatus, mastoid process, styloid process, zygomatic process; Spheniod bone, sella turcica, sphenoidal sinuses; Ethmoid bone, cribiform plates, perpendicular plate, superior nasal concha, middle nasal concha, ethmoid sinuses, crista galli

4. Complete parts A and B of the Lab Handout

5. Examine the facial bones of the skull specimens, both articulated and disarticulated and locate the following: Maxillary bones, maxillary sinuses, palatine processes, alveolar process, alveolar arch; Palatine bones; Zygomatic bone, temporal process, zygomatic arch; Lacrimal bones; Nasal bones; Vomer bone; Inferior nasal concha; Mandible, mandibular condyle, coronoid process, alveolar arch

6. Complete Part C, D & E of the Lab Handout

7. List the structures found on the bones of the Skull (those listed above) and describe their individual functions; ie. specific articulation or muscle attachments

8. As you complete the lab, Review the "Lab Objectives" from the handout and write a synopsis of the lab addressing the four objectives.
