The anatomical description of the temporomandibular joint and the cervical spine.

THE CERVICAL SPINE:

Is composed by seven vertebraes, and we can separate it in two parties: 

• The superior cervical spine: is composed by C1 (Atlas) and C2 (Axis) 
• The inferior cervical spine: is composed by the vertebraes from C3 to C7

It permits mouvements of: 

• Flexion/Extension
• Lateral inclination
• Rotation and the half part of the rotation is permit by the C1-C2 articulation.

THE TEMPORO MANDIBULAR JOINT:

Is composed by the temporal bone more precisely by the temporal fose, and the condyle of the mandibular bone, between them we found a meniscus. It's the only movable joinf of the face. 

We can do many mouvements like:

• Protraction/ Retraction
• Elevation/ Lower the mandible
• Lateralization of the mandible bone

This is a video wich shows the mouvement of the condyle when we open our mouse.
