Branches of 3d part of maxillary artery

Drive, Park Influenced - Arrested + Sentenced
-Descending palatine artery (divides into greater and lesser palatine arteries)
-Posterior superior alveolar
-Artery of pterygoid canal
-Sphenopalatine artery
Maxillary nerve enters pterygopallatine fossa via_
Foramen rotundum
Branches of maxillary nerve

I (saw) 2 Zebras
Infraorbital - terminal and largest branch of maxillary nerve, passes through infraorbital foramen

2 pterygopallatine nerves - form PPG

Zygomatic nerve - splits into zygomaticofacial and zygomaticotemporal, zygomaticotemporal give branch that supplies postganglionic parasympathetic fibers to lacrimal gland via lacrimal nerve
Describe nerve of pterygoid canal
Consists of 2 nerves - deep petrosal and greater petrosal
Deep petrosal - postganglionic sympathetic fibers from internal carotid plexus, fibers come from superior cervical ganglion
Postganglionic sympathetic fibers go through ganglio w/out synapsing and distribute via branches of maxillary nerve

Greater petrosal - preganglionic parasympathetic fibers and taste fibers, preganglionic fibers synapse in PPG

Hypoglossal nerve (CN XII)
-Palatoglossus - vagus nerve (CN X)
Muscles supplied by facial nerve - CN VII
- All muscles of facial expression
-Posterior belly of digastric
Muscles supplied by mandibular nerve (V3)
-4 muscles of mastication
-2 tensors (veli palatini and tympani)
-anterior belly of digastric
All intrinsic muscles of larynx are supplied by _ EXCEPT
Recurrent laryngeal nerve (branch of CN X)
Cricothyroid - superior laryngeal nerve
All infrahyoid muscles are supplied by _ EXCEPT
Ansa cervicalis (C1-C3)
Geniohyoid - those two muscles are supplied by C1 via hypoglossal nerve
SCM and trapezius are supplied by _
CN XI - spinal accessory nerve
Scalenes are supplied by _
Direct branches of ventral rami of cervical spinal nerves
Postganglionic sympathetic fibers from superior cervical ganglion supply _
Also orbitalis and smooth muscle part of levator palpebrae
Postganglionic parasympathetic fibers supply
-Constrictor pupillae
-Ciliary muscles
-Also glands of nasal cavity, salivary and lacrimal glands
Nasal conchae
Three shelf like projections of lateral nasal wall - superior, middle and inferior
Nasal meatuses
Spaces under conchae - superior, middle and inferior
Sphenoetmoidal recess
Space above superior nasal concha
Ethmoidal bulla
-Rounded elevation below and behind middle nasal concha
-Contains middle ethmoidal air cells
Hiatus semilunaris
-Semicircular groove below ethmoidal bulla
Nasal vestibule
-Contains hairs that filter incoming air
Nerve supply of nasal cavity
-Anterior ethmoidal nerves - innervate anterior part of nasal cavity including septum and lateral walls, terminate as external nasal nerve
-Branches of PPG
-Olfactory nerves - innervate mucosa
Most of nasal septum is innervated by _
Nasopalatine nerve
Blood supply of nasal cavity
-Anterior and posterior ethmoidal arteries
-Sphenopalatine artery
-Greater palatine artery
Innervation of frontal sinuses
Supraorbital nerve
Innervation of maxillary sinuses
Supplied by superior alveolar and infraorbital nerves

Chorda tympani (CN VII)
General sensation and taste of posterior 1/3 of the tongue
Lingual branch of CN IX
General taste and sensation of valleculae
Internal laryngeal nerve (CN X)
Motor to all muscles of tongue except palatoglossus
Hypoglossal CN XII
Intrinsic muscles of the tongue
Withing the tongue - no bony attachments, arranged as transverse, longitudinal and vertical sheets. Responsible for major shape change
Genioglossus action
Pulls tongue forward and protrudes
Hyoglossus action
Depresses tongue
Styloglossus action
Pulls tongue backward and upward
Palatoglossus action
Elevates tongue and approximates palatoglossal folds
Blood supply of tongue
