Styloid Process,
Mastoid Process Tympanic part of Temporal Bone |
|
|
Roof
|
Great Wing of Sphenoid
Other features: Mandibular Fossa Articular Eminence Foramen Rotundum Foramen Ovale Infratemporal Crest |
|
|
Lateral Wall
|
Ramus of Mandible
|
|
|
Temporalis Fascia
|
covers the temporalis muscle; attaches along the
zygomatic process. (This must be removed to clean the temporalis.) |
|
|
Temporalis
|
occupies temporal fossa
|
|
|
Masseter
|
on lateral surface of mandibular ramus
|
|
|
Lateral Pterygoid
|
in infratemp fossa, superior to medial pterygoid; has
horizontally-oriented fibers |
|
|
Medial Pterygoid
|
in infratemp fossa, inferior to lateral pterygoid; with
vertically-oriented fibers |
|
|
Maxillary 1st Part
|
passes posterior to neck of mandible to enter infratemp
fossa; it gives off some branches like inf. alveolar a. and then may course deeply between the lateral and medial pterygoid muscles. |
|
|
Inferior alveolar artery
|
accompanies the inferior alveolar n. into the mandibular
foramen and canal |
|
|
Deep temporal arteries
|
on deep surface of temporalis; accompanies deep
temporal ns. |
|
|
Masseteric a.
|
It courses through mandibular notch to deep surface of masseter
|
|
|
Pterygoid venous plexus, Between the pterygoid and temporalis
|
it is collapsed and is in the
fascia |
|
|
Inferior alveolar n.
|
in pterygomandibular space; posterior to lingual n;
enters the mandibular foramen along with inferior alveolar a |
|
|
Mylohyoid n.
|
branches from posterior surface of inferior alveolar n.,
just before the IAN enters the mandibular foramen |
|
|
Lingual n.
|
in pterygomandibular space, anterior to the IAN; courses
medial to mandible – not within it – toward tongue |
|
|
Deep temporal nerves
|
course on the deep surface of temporalis; they
accompany the deep temporal arteries |
|
|
Long buccal nerve
|
courses anteriorly to buccal region; is often found
coursing in the vertical fibers of the anterior margin of the temporalis |
|
|
Masseteric n
|
courses over the mandibular notch and is accompanied
by the masseteric a |
