Directions

Within the lesson click the red linked headings to lug up the desired beginning point within the cadaver for your job-related. Use the provided imperiods on the worksheet to annotate and also recognize specific anatomical frameworks.

Anterior Skull

Using the highlight tool identify the complying with bones of the anterior skull.

You are watching: Why can the sphenoid bone be called the keystone of the cranial floor

frontal bone zygomatic bones (ideal & left) maxilla mandible (note: 9 parts of the mandible are figured out. At this point you are only responsible for the single unified bone.) nasal bones (best & left) (note: these are figured out as a single bone in your virtual cadaver) ethmoid

At birth, the frontal bone has actually two components separated by a frontal suture (immovable joint). This suture primarily disshows up by the age of 6 when the frontal bones unite.

Identify the bones and also test your identification knowledge via your online cadaver. Furthermore, you must mark the diagrams in your worksheet. Labeling and highlighting diagrams is VERY useful once finding out anatomy.

Lateral Skull

Aobtain, making use of the highlight tool identify the complying with bones of the lateral skull.

tempdental bone (right) frontal bone parietal bone (right) occipital bone (note: 2 parts of the occipital bone are identified. You, yet, are only responsible for the single linked bone at this suggest.) maxilla mandible zygomatic bone (right) sphenoidal bone nasal bone (right)

Dissect amethod the maxilla, frontal, and nasal bones.

Locate and also highlight the ethmoid. Ethmoid indicates "favor a sieve" which is a little evident from your dissection. Structurally, the ethmoid creates component of the cranial floor, the medial wevery one of the orbits (eye sockets), part of the nasal septum, and also component of the sidewalls of the nasal cavity.

Using the interenergetic photo, identify each of the adhering to components of the ethmoid, which are also little to observe in your dissection.

Sphenoid

Dissect away the maxilla, the ideal and also left zygomatic bones, the ethmoid, and also the nasal bone.

Sphenoid implies "wedge shaped" however from the anterior check out it looks even more prefer a butterfly. It is commonly described as the "keystone of the cranial floor" bereason it articulates via all the other cranial bones and holds them together. From a premium vantage point, you can really watch how it is main in its area and holds the surrounding cranial bones in place.

Using the interenergetic photo, determine each of the adhering to components of the sphenoid. As with the ethmoid, these structures are not quickly viewed in the disarea.


Posterior Skull

Using the highlight tool recognize the adhering to bones of the posterior skull.

occipital bone tempdental bones (appropriate & left) parietal bones (best & left) sphenoidal bone

Occipital Bone


Locate the following through the interactive photo. Then find them on the cadaver, and record them on your worksheet.

Sutures


Sutures are the immovable joints in between skull bones. Names, such as the frontozygomatic or sphenoparietal sutures, plainly reflect the bones they unite. Others, such as the coronal suture, do not.

These sutures are plainly visible in your dissection, yet they are not particularly determined. Identify each of the following. Then find them on your speciguys, and record them on your worksheet.

Sutural bones, also dubbed wormian bones, are tiny bones located within the sutures. The number of sutural bones varies widely in between people.
