Salivary Glands Flashcards
Borders of Parotid Bed
✓Anterior; Ramus of mandible, masseter
✓Posterior; Mastoid process
✓Superior; External acoustic meatus and
zygomatic process of temporal bone
✓Medially; styloid process, posterior belly of
digastric muscle, stylohoid m, styloglossus m,
stylopharyngeus m.
✓Laterally; parotid fascia & skin
Parotid Duct pierces
Buccinator muscle
Surfaces of Parotid Gland
➢Superior surface
➢Superficial surface
➢Anteromedial surface
➢Posteromedial surface
Auriculotemporal nerve is closely
related to
superior surface
great
auricular nerve,
Superficial Surface
Facial nerve emerges
from
Anteromedial surface of parotid
Posteromedial Surface
Related to ;
• mastoid process
• Scm muscle
• Posterior belly of
digastric muscle
• Styloid process &
ascociated muscles
Internal carotid a. and
internal juguler vein
are seperated from
the gland by the
styloid process and its
muscles
External carotid
artery grooves
Posteromedial surface
Structures Transversing The Parotid
Gland
✓External carotid artery
✓Retromandibular vein
✓Facial nerve
External Carotid Artery gives branches…………………… in parotid gland
Superficial temporal artery maxillary artery
Sometimes posterior auricukar artery
Terminal branches of
facial nerve;
- Temporal
- Zygomatic
- Buccal
- Marginal mandibular
- Cervical
Vessels of Parotid Gland
External Carotid Artery ! External Juguler Vein !
Lymphatics of Parotid Gland
To superficial and
deep cervical lymph
node
Innervation of Parotid Gland
• Tympanic branch of the
glossopharyngeal nerve to
otic ganglion
• From the otic ganglion
auriculotemporal nerve
carries the secretory
fibers to the gland
