If you are looking for a skull model that can be used to demonstrate the function of the masticatory muscles and that covers most needs, we highly recommend this one.

The skull model has been developed to demonstrate the movements of the jaw using elastic bands that represent the masticatory muscles. The model is cast in robust plastic and comes in a size that corresponds to an adult person. The dimensions are 23.2 x 16.7 x 16.7 cm and the weight is approximately 900 grams. The skull cap ("the top") can be removed, so i.a. the base of the skull (basis cranii interna) can be studied.

Anatomical features

Anatomically, it must be emphasized that this skull model offers an educational opportunity to both study the muscles of mastication and demonstrate their function. The masticatory muscles are:

M. masseter
M. temporalis
Lateral pterygoid muscle
M. pterygoid medialis

The 4 masticatory muscles are represented on both sides of the skull model by means of elastic bands, which are also named by the attachments on the skull (see the pictures on the left). Read more about the movement below.

Generally speaking, the human skull can be divided into 2 parts, and the skull model therefore shows the following:

1) The braincase (neurocranium), which is intended to enclose the brain and the hearing-equilibrium organ

2) The facial skeleton (viscerocranium) which surrounds the nasal cavity and forms the tooth-bearing framework around the oral cavity. The 32 teeth are also included

The braincase consists of 8 bones. There are 4 unpaired (the frontal, sphenoid, sphenoid and occipital bones) and 2 paired (the occipital and temporal bones). All these bones as well as sutures can be identified on the skull model.

The facial skeleton includes 6 paired bones (the maxilla, palatine, cheekbone, nasal bone, lacrimal bone, and lower conchbone) and 3 unpaired bones called the mandible, the ploughshare, and the zygomatic bone (some do not count the zygomatic bone as part of the facial skeleton). All these bones and sutures can also be identified on the skull model. NB: The hyoid bone is also included in the facial skeleton but cannot be seen on this skull model.

The human skull contains many holes and channels containing vessels and nerves. Overall, there are connections between the braincase and the neck, to and from the eye socket, to and from the pterygo-palatine fossa and to and from the nasal cavity.

This skull model shows many of the most important holes and canals, but not all. Furthermore, the level of detail on the bones is good. As for "osseous landmarks" such as the processus styloideus, many of the most important are seen, while some minor participants are omitted.

Product flexibility

In terms of movement, this skull model is molded and developed to be able to demonstrate the function of the masticatory muscles by:

Jaw closure
Initial jaw opening
Movement of the lower jaw to the side and forward

Clinical features

Clinically, the skull model can be used to understand diseases and disorders in the jaw joint and masticatory muscles, such as jaw tension and temporomandibular dysfunction (TMD).

The model is also ideal for understanding other diseases, disorders and disorders in this part of the skeleton.
