Linear Guide
linear guide -common carotid artery
A point from the sternoclavicular articulation to the anterior surface of the lobe of the ear.
anatomical guide- common carotid artery
Along the medial border of the sternocleidomastoid muscle (SCM).
Begins at the level of the right sternoclavicular articulation and terminates at the level of the superior border of the thyroid cartilage on the right side of the neck.
right common carotid artery
Begins at the level of the second left costal cartilage and terminates at the superior border of the thyroid cartilage on the left side of the neck.

Place of incision to raise common carotid artery
Supraclavicular incisionParallel incisionHalf-moon incision
Place of incision to raise common carotid arteryperformed on top of or above the clavicle. Along the superior border of the clavicle. - commonly used for an emaciated case, or death of an adolescent female ( when you are anticipating clothing with a low cut neckline)
Supraclavicular incision
Place of incision to raise common carotid arterymost common incision used to raise common carotid artery to surface. Along the posterior border of the inferior one third (1/3) of the sternocleidomastoid muscle.
Parallel incision
Place of incision to raise common carotid arteryvisually looks like a smiley face; made between two medial ends of the collar bones, allows you to raise both common carotid arteries to the surface. (Head trauma, major restorative art projects)
Half-moon incision
What is the most common incision to raise common carotid artery to surface?
Parallel incision
Considerations of raising common carotid artery
Ensures direct distribution to the face. Close to the center of circulation (arch of aorta). Has no branches except terminal branches. Face may be embalmed with milder solution than remainder of the body with restricted cervical injection.
Precautions of raising common carotid artery
Incision may be visible after dressing. Tubes may leave marks on the face. The face may be over injected.
Accompanying Vein of the common carotid artery
nternal jugular vein
where is the internal jugular vein located
Located lateral and superficial in relationship to the common carotid artery. (Usually the first you see)
The aorta has three distinct divisions, which are going away from the heart. What are they?
Ascending aortaArch of aortaDescending aorta
first division of the aorta - the blood is going superiorly (upper direction) away from the heart.
ascending aorta
What are the two branches that arise off the ascending aorta.
The left and right coronary arteries, which form a crown around the heart muscle. They are the only arteries that feed the heart muscle itself. Off two of the cusps of the aortic semilunar valve is the origin of the coronary arteries.
second division of the aorta - this is the center of circulation in embalming. It will ensure distribution to both sides of a person’s head, neck, and upper extremities.
Arch of the aorta
There are three distinct branches or divisions off the arch of the aorta. They are listed in the order they arise moving away from the heart. What are they?
Brachiocephalic artery Left common carotid artery Left subclavian artery
first branch to rise off the arch aorta - (unpaired) this will eventually provide blood to the right side of the head and neck, and the right upper extremities.
Brachiocephalic artery
The brachiocephalic artery will split into
the right subclavian artery (located under the right collar bone).
the branch that feeds the right side of the head and neck. It is the most frequent artery raised and used artery in embalming. Starts where the sternum and the right collar bone meet.
Right common carotid artery
