Pterygopalatine ganglion

4. The Pterygopalatine ganglion
(Meckel s ganglion ,Nasal
ganglion or Sphenopalatine
ganglion).

5. It lies in
Pterygopalatine
Fossa.
It is suspended by
Nerve root from
Maxillary nerve
.

7. Preganglionic parasympathetic
fiber comes via Greater
petrosal nerve (from facial
nerve) which arises from
superior salivary nucleus.

8. Preganglionic Sympathatic fiber
arises from plexus around the
internal caroted artery via a
deep petrosal nerve.

9. Parasympathetic postganglionic (secretomotor) fibers
from this ganglion innervate lacrimal Gland via
zygomatic branch .
Postsynaptic sympathetic fibres from superior cervical
ganglion join branches of pterygopalatine nerves
These supply blood vessels of
Nasal cavity
Palate
Superior part of pharynx
