what structures are in the posterior triangle of neck
accessory nerve
brachial plexus
external jugular vein
subclavian artery and vein
what structures are in the anterior triangle of neck
submental - lymphnodes
submandibullar - glands, hypoglossal nerve, facial artery and vein
carotid - sheath, glossopharyngeal nerve, deep cervical lymph nodes
muscular triangle - sternohyoid, thyrohyoid, sternothyroid, larynx, thyroid gland

name the eight branches of the external carotid artery
some anatomist like freaking out poor med students sup. thyroid artery ascending pharyngeal artery lingual artery occipital artery post. auricular artery maxillary artery sup. temporal artery
how does venous drainage of the face happen
drains through facial vein which then drains into internal jugular vein which then drains into subclavian vein
what sensory information does the trigeminal nerve innervate
opthalmic - top of cranium, upper eyelid, upper part of nose
maxillary - side of forehead, lower eyelid, lower nose/nostrils
mandibullar - front ear, mandible, lower lip
which layer of scalp of blood vessels located
Loose Areolar Connective Tissue
what jugular veins are responsible for the head and neck
external, internal and anterior
what forms external jugular vein
post. auricular vein and retromandibullar vein
what forms the retromandibullar vein
maxillary and superficial temporal veins, which drain the face
what does the anterior jugular vein do
paired veins that drain anterior aspect of neck, emptying into subclavian
