- what type of nerves are UNIQUE to cranial nerves?
- Special Sensory (smell, vision, taste, hearing and balance).
- Somatic Sensory Nerves
- Information regarding body position (proprioreception), pain, temperature, vibration and touch from somatic structures (skin, body wall)
- Somatic Visceral Nerves
- Information regarding sensations (except pain) from the viscera (organs, glands) in the thoracic, abdominal and pelvic cavities
- Visceral Motor (Autonomic)
- Innervation of cardiac muscle, smotth muscle, and glands
- Branchial Motor
- Innervation to muscles derived from branchial arches (muscles of mastification, facial expression, pharynx and larynx)
- Somatic Motor
- Innervation of the skeletal muscles derived from myotomes (includes tongue and extraocular muscles)
- 3 branches of OPTHALMIC NERVE
-
Nasociliary
Lacrimal
Frontal - Branches of the FRONTAL NERVE
-
Supratrochlear
Supraorbital
Nerve to frontal sinus - Branches of the NASOCILIARY NERVE
-
Anterior Ethmoidal
Posterior Ethmoidal
Internal Nasal
External Nasal
Infratrochlear
Meningeal
Long cilary
Short cilary - Lacrimal Nerve's invovlement in ANS
- postganglionic parasympathetic fibers to the pterygopalatine gangion to the lacrimal gland
- Branches of the Maxilary (V2)
-
Infraorbital
Zygomatic
Palatine
Meningeal - Branches of INFRAORBITAL NERVE
-
Anterior superior alveolar
Muddle superior alveolar
posterior superior alveolar - Branches of the Zygomatic Nerve
-
Zygomaticofacial
Zygomaticotemporal - Branches of the Palatine Nerve
-
Greater Palatine
Lesser Palatine - what does the meningeal nerve innervate?
- dura mater
- Maxillary (V2) function in ANS of head
-
zygomaticotemporal carries postgangionic fibers from pterygopalantine gangla to lacrimal gland
Palatine nerves carry taste fibers that pas through pterygopalatine ganglia and travel with nerve of pterygoid canal and gerater petrolsal nerve to goin with facial nere for taste fibers
