Veins usually run with
Arteries and have the same names
Exceptions are jugulars
Jugular foramen

Pterygoid plexus of veins
Forms max. Vein
Can be pierced when anesthetizing PSA nerve block
Hematoma
Swelling and discoloration due to piercing of a vein
What forms the retromandibular vein
Superficial temporal/max. Veins
Retromandibular vein divides into
Posterior retromandibular vein and joins posterior auricular vein
What forms the external jugular vein
Posterior retromandibular vein and posterior auricular vein
External jugular empties into the
Subclavian vein
Anterior retromandibular vein joins facial vein
Common facial vein - internal jugular
Cavernous sinus
Venous sinus near base of the brain
Dangerous if infection spreads into this area
External jugular to the subclavian vein joins internal jugular
Brachiocephalic vein and flows into superior vena cava - heart

Exocrine Merocrine Compound tubuloaveolar Serous Seromucous Mucous
What are the major salivary glands
Parotid
Submandibular
Sublingual
Mumps

Parotid
Parotid
On surface of masseter, behind ramus, anterior to ear
Serous
Duct (Stensons) opens into the oral cavity opposite the max 2nd molar
60-65% of total resting salivary volume
Submandibular
What kind of salivary gland is the submandibular
Mixed gland (seromucous)

Wraps around mylohyoid muscle and located inferior/posterior to body of mandible
Submandibular
Smallest - 10% of total salivary volume
