1)
Lateral pterygoid plate is a
boundary of infratemporal fossa laterally.
2)
The inferior surface of the
greater wing of the sphenoid is a boundary of infratemporal fossa superiorly.
3)
Pterygoid venous plexus are the
one of the contents of infratemporal fossa.
4)
Chorda tympani also are the one of
the contents of infratemporal fossa.
5)
There is no otic ganglion in
infratemporal fossa.
6)
Lateral surface of the lateral
pterygoid plate is the origin of superior head of lateral pterygoid muscle.
7)
Lateral pterygoid muscle inserts
at articular disc.
8)
The main function of lateral
pterygoid muscle is depressor and protractor of mandible.
9)
Hypoglossal nerve supplies the
lateral pterygoid muscle.
10)
Relations of lateral pterygoid
muscle are temporalis and masseter muscles superficially.
11)
Relations of lateral pterygoid
muscle are deep temporal nerve and masseteric nerve at the lower border.
12)
Pterygoid artery is the branches
of third part of maxillary artery.
13)
Anterior tympanic artery is the
branches of first part of maxillary artery.
14)
Infraorbital artery is the
branches of second part of maxillary artery.
15)
Pterygoid plexus of veins situated
around the medial pterygoid muscle.
16)
Nerve to medial pterygoid muscle
is the branches of mandibular nerve from posterior division of trunk.
17)
Otic ganglion is a peripheral
parasympathetic ganglion which supply secretomotor fibres to parotid gland.
18)
The chorda tympani nerve is
connected to otic ganglion.
19)
Regarding of temporomandibular
joint, articular surface covered by hyaline cartilage instead of
fibrocartilage.
20)
Articular disc is attached to the
tubercles of the head of the mandible.
21)
The mandibular condyle is convex
in all directions but wider latero-medially.
22)
Articular disc helps to
accommodate a hinging action as well as the gliding actions.
23)
Fibrous capsule is attached to the
articular tubercle anteriorly.
24)
Stylomandibular ligament is
attached to styloid process to the angle of the mandible.
25)
Temporomandibular joint is
supplied by superficial temporal artery and masseteric nerve.
