1st division of largest artery after blood leave heart going upward; aorta portion traveling up from heart which branches off to left & right coronary.
ASCENDING AORTA
A. LEFT CORONARY
B. RIGHT CORONARY
Left branch off Ascending Aorta that provides blood to heart muscle only
LEFT CORONARY
Right branch off Ascending Aorta that provides blood to heart muscle only
RIGHT CORONARY
ARCH OF THE AORTA
ARCH OF THE AORTA A. BRACHIOCEPHALIC 1.RIGHT SUBCLAVIAN a) VERTEBRAL ARTERIES b) INTERNAL THORACIC 2.RIGHT COMMON CAROTID B. LEFT COMMON CAROTID C. LEFT SUBCLAVIAN
1st division of largest artery after ascending aorta; it arches behind heart on way to feed torso & lower extremities. Center of circulation in embalming; it has 3 branches off it
ARCH OF THE AORTA
1st branch directly off Arch of Aorta; unpaired or single artery. Eventually feeds right side of head & neck & right extremities. Branches into 2 arteries
BRACHIOCEPHALIC
Named by location under right collarbone & off brachiocephalic, feeds right upper extremities
RIGHT SUBCLAVIAN
pair that branch upwards and go thru 7 cervical vertebrae to feed blood brain; unite together in cranial; in autopsy case during embalming these clipped arteries leak inside autopsy cranial
VERTEBRAL ARTERIES
most popular initial point of injection used to embalm non-autopsy cases; feeds right head & neck
RIGHT COMMON CAROTID
2nd branch directly off Arch of Aorta; feeds head and neck on left side
LEFT COMMON CAROTID
point of either side of neck where common carotid terminates & splits into internal & external carotid artery
Carotid Sinus
feed outside skull (face scalp hair)
External Carotid Artery
RIGHT EXTERNAL COMMON CAROTID ARTERY – 8 BRANCHES
FACIAL:
- SUPERIOR THYROID ARTERY
- LINGUAL ARTERY
- FACIAL ARTERY
- MAXILLARY ARTERY
- SUPERFICIAL TEMPORAL ARTERY
AURICULAR:
- ASCENDING PHARYNGEAL - AURICULAR
- OCCIPITAL ARTERY - AURICULAR
- POSTERIOR AURICULAR ARTERY
1st branch to arise off facial side of external carotid artery; feeds superior portion of thyroid gland
SUPERIOR THYROID ARTERY
2nd branch to arise off facial side of external carotid artery; feeds the tongue
LINGUAL ARTERY
3rd branch to arise off facial side of external carotid artery; most important branch for embalming process key artery to embalm face; feeds the face cheek lips mouth nose & eyelids.
FACIAL ARTERY
4th branch to arise off facial side of external carotid artery; feeds maxilla (upper jaw); upper teeth and by location muscles of mastication for chewing & swallowing
MAXILLARY ARTERY
1st branch to arise off AURICULAR (toward ear) of external carotid artery; feeds pharynx (throat) soft palet of mouth roof
ASCENDING PHARYNGEAL
5th and most superior branch to arise off facial side of external carotid artery; feeds forehead region or anterior 1/3; during embalming veins in forehead protrude
SUPERFICIAL TEMPORAL ARTERY
2nd branch to arise off AURICULAR (toward ear) of external carotid artery; feeds occipital (posterior) region of back scalp
OCCIPITAL ARTERY
3rd most superior branch to arise off AURICULAR of external carotid artery; goes behind the ear; feeds middle or lateral 1/3 of scalp
POSTERIOR AURICULAR ARTERY
3rd & last branch directly off Arch of Aorta; eventually feeds left upper extremities
LEFT SUBCLAVIAN
3rd & last branch directly off Arch of Aorta; eventually feeds left upper extremities; common for embalming of left side
LEFT SUBCLAVIAN
Branch off subclavian; width of pencil lead; goes inferiorly/downward; runs entire ventral aspect of torso; secondary route of circulation; in embalming autopsy case when injecting thru subclavian there’s leakage in small cut internal thoracic
Interior thoracic
(Deep brachial) feeding posterior muscle of arm/triceps brachia muscle
PROFUNDA BRACHII
most lateral artery of forearm; last chance to raise in embalming
RADIAL artery
most medial artery of forearm; last chance to raise in embalming
ULNAR artery
At wrist level feeds top of hand from wrist area; arch structure that lye deep in tissue
DEEP Palmar ARCH
At wrist level (Volmar Arch) Feeds palm side of hand from wrist
SUPERFICIAL PALMAR ARCH
individual arteries off Deep Palmar artery that feeds fingernail surface of digits
Radial DIGITAL ARTERY
individual arteries off Superficial Palmar Arch that feeds palm side of digits
Ulnar DIGITAL ARTERY
Network of arteries at the base of the brain that represents the anastamosis of the distal ends of both left and right vertebral arteries and both left and right internal carotid arteries.

- ANTERIOR COMMUNICATING ARTERY
union or joining together of blood vessels; can be surgically reattached
Anastamosis
branch from subclavian superiorly passes thru foramen magnum. Inside cranium they join to make basilar artery.
VERTEBRAL ARTERY LFT/RT
passes through carotid canal of skull from carotid sinus; largest size artery to bring blood to brain; feeds insides skull; severed at autopsy
INTERNAL CAROTID ARTERY LFT/RT
single/unpaired; formed by union of left & right vertebral arteries
BASILAR ARTERY
feeds posterior portion of cerebral brain tissue
POSTERIOR CEREBRAL ARTERY LFT/RT
does not feed any specific part of brain tissue; it communicates or joins the internal carotid with posterior cerebral; rt joins rt lft joins lft
POSTERIOR COMMUNICATING ARTERY LFT/RT
continuation of internal carotid; feeds middle portion of cerebral hemisphere
MIDDLE CEREBRAL ARTERY LFT/RT
feeds anterior portion of cerebral brain tissue
ANTERIOR CEREBRAL ARTERY LFT/RT
feeds left eye
OPHTHALMIC ARTERY LFT/RT
single/unpaired; small interconnecting arteries; communicate or join lft/rt anterior cerebral arteries; common branch arising from both anterior arteries; does not feed any specific part of the brain tissue
ANTERIOR COMMUNICATING ARTERY
