Temporal Bone

TEMPORAL

It is an even bone, very complex, it is important because inside is the hearing aid.

It is divided into 3 parts:

  • Flaky
  • Tympanic
  • Petrosa
 

 

 

Scaly Part

 Zygomatic process & #8211; long arch protruding from the bottom of the scale

 Mandibular Fossa & #8211; articulates with the condyle of the jaw

Tympanic Part

 External Acoustic Meato

Petrosa (Pyramid)

 Styloid Process & #8211; acute spine located on the underside of the temporal bone

 Mastoide Process & #8211; chronic projection that may vary in size and shape

 Internal Acoustic Meato & #8211; gives passage to the facial, acoustic and intermediate nerve and the internal auditory branch of the basilar artery

 Stylomastoid foramen & #8211; is located between the mastoid and styloid process

 Carotic Channel & #8211; gives way to the internal carotid artery and the carotid nervous plexus

 Jugular Fossa & #8211; houses bulb of internal jugular vein

THE Temporal articulates with 5 bones: Occipital, Parietal, Zygomatic, Sphenoid and Mandible.
