embalming I - carotids

R common carotid origination

originates at the brachiocephalic

R common carotid termination

terminates as it bifurcates into the external and internal carotid

R common carotid drainage

drains into the jugular vein

L common carotid origination

originates at the aortic arch

L common carotid termination

terminates as it bifurcates into the external and internal carotids

L common carotid drainage

drains into the internal jugular

linear guide of the common carotid

a line from a point over the respective sternoclavicular articulation to a point over the anterior surface of the base of the respective earlobes; sternoclavicular articulation - front lower earlobes

anatomical guide of the common carotid

posterior to the medial border of the scm

R common carotid anatomical limit

begins at the right sternoclavicular articulation and extends to the superior border of the thyroid cartilage

L common carotid anatomical limit

begins at the level of the second costal cartilage and extends to the superior border of the thyroid cartilage

anatomical positioning of the carotid arteries

from superficial to deep: vein, artery, nerve..... from lateral to medial: vein, nerve, artery

carotid sheath

The deep fascia that covers the common carotid artery; it is posterior and parallel to the SCM

vagus nerve

nerve that is inbetween the carotid artery and vein; posterior to both

platysma

muscle that covers most relevant structures in the neck

omohyoid muscle

muscle that crosses anteriorly over the carotid sheath

external jugular

vein that is on the outer surface of the SCM

external carotid

bifurcation of the common carotid that supplies blood to the superficial face

internal carotid

bifurcation of the common carotid that supplies blood to the brain

anterior cervical triangle

contains the common, external, and internal carotid arteries and is covered by the platysma - also contains the internal jugular vein and the vagus nerve

ascending pharyngeal artery

supplies the pharynx

superior thyroid

supplies thyroid

lingual

supplies the mouth

facial

feeds the mouth/superficial face

occipital artery

feeds the posterior neck

posterior auricular

feeds the ear

maxillary artery

feeds the upper jaw

superficial temporal

feeds the scalp

opthalmic

feeds the eye

anterior cerebral

feeds the anterior brain

middle cerebral

feeds the midbrain

posterior communicating

feeds the brain

choroidal branches

feeds the brain

supraclavicular incision

an incision that is made directly along the clavicle

anterior vertical incision

incision that is made directly along the SCM

posterior vertical incision

incision that is made posterior to the SCM

anterior horizontal incision

incision that is made at the base of the neck

semilunar incision

incision that is made across the upper chest in an arc

strap line incision

incision that is made near the shoulder that is easily concealed

facial artery

artery that reaches superficial tissues - incision is made along the inferior border of the mandible, just anterior to the angle of the jaw
