  • Front
  • Back
what is the parotid gland situated between
mandible and external auditory canal
GSA - general sensory
via auriculotemporal branch of V3 & great auricular nerve (C2,3)
GVE: sympathetic innervation carried from
superior cervical ganglion (T1-T4) to the gland via a nerve plexus on the surface of the external carotid artery
GVE: preganglionic parasympathetic innervation is from
CN IX via the lesser petrosal nerve to the otic ganglion
postganglionic parasympathetic innvervation carried into gland by the
auriculotemporal nerve
masticatory space
fascia enclosed compartment that includes temporal and infratemporal fossae
all the muscles of mastication are innervated by
the mandibular division of the trigeminal
only division of the trigeminal that contains motor fibers
mandibular division of the trigeminal
mandibular division of the trigeminal enters the ..
infratemporal fossa
mandibular division of the trigeminal enters the infratemporal fossa from the
middle cranial fossa
mandibular division of the trigeminal enters the infratemporal fossa from the middle cranial fossa via the
foramen ovale
important dental branches of the mandibular division include
long buccal (anterior division)

auriculotemporal

lingual

inferior alveolar (posterior division)

terminal branches of the inferior alveolar
terminal branches of the inferior alveolar include:
mylohyoid

mental

incisive
primary blood supply to the infratemporal fossa
maxillary artery - one of the two terminal branches of the external carotid artery
maxillary artery is subdivided into 3 parts based upon its relationship to the lateral pterygoid muscle
part 1: mandibular - from its origin to inferior border of the muscle

part 2: pterygoid

part 3: maxillary
venous drainage
dense venous plexus

petygoid venous plexus envelopes the muscles of mastication within the infratemporal fossa and coalesces to form the maxillary vein
maxillary vein drains posterior and joins with the ...
superficial temporal vein to form the retromandibular vein within the parotid region
pterygiod venous plexus - communications
cavernous sinus

facial vein

inferior ophthalmic vein

pharyngeal plexus
structures traversing the parotid gland
facial nerve

retromandibular vein

external carotid artery --> maxillary and superficial termporal arteries

auriculotemporal nerve
sensory branches of the posterior division of V3
auriculotemporal

lingual

inferior alveolar

- mental
- incisive
branches off the stem of the V3
medial pterygoid nerve

tensor tympani nerve

tensor palatini nerve

meningeal branch
motor branches of the anterior division of V3
deep temporal

masseteric

lateral pterygoid
sensory branches of the anterior division of V3
long buccal nerve
what supplies sensory and pierces buccinator
long buccal nerve
what joins the lingual nerve in the inferior temporal fossa
chorda tympani
chorda tympani is a branch of which CN
CN VII
what are the functional components of the chorda tympani
SSA - special sensory

GVE - general visceral efferent to submandibular and lingual salivary glands
where are the cell bodies of the special sensory neurons of the chorda tympani
geniculate ganglion
what muscles are involved in protrusion of the mandible?
lateral pterygoid muscles
medial pterygoid muscles
masseter muscles
what muscles are involved in retrusion of the mandible?
posterior portion of the temporalis muscles
deep portion of masseter muscles
what muscles are involved in lateral movements of the mandible?
...
