Internal Features of the Left Atrium
Openings for the pulmonary veins
Left atrioventricular valve

Posterior Vessels of the Heart
Aortic Arch
Descending Aorta (ascending is anterior)
Left and Right Pulmonary Arteries
Left and Right Pulmonary Veins (2 sets of 2)
Vessels of the Aortic Arch
brachiocephalic trunk (branches to right CC and right sub)
left common carotid artery (more medial)
left subclavian artery (right is a division of brachiocephalic trunk)
Anterior Vessels of the Heart
Pulmonary Trunk (tucked under arch)
Right coronary Artery (in coronary sulcus)
Left Coronary Artery (just below and to the side of the trunk)
Vessels draining the heart
Great Cardiac Vein (in the anterior ventricular sulcus)
Middle Cardiac Vein (in the posterior interventricular sulcus)
Coronary Sinus (Posterior portion of the coronary sulcus)
Muscles of the Eye
Medial Rectus Muscle
Lateral Rectus Muscle
Superior Rectus Muscle
Inferior Rectus Muscle
*Rectus means straight
Superior Oblique Muscle Inferior Oblique
Three tunics of the eye
Fibrous Tunic
Vascular Tunic
Neural Tunic (not bold)
Fibrous tunic
Sclera: the white
Cornea
Vascular tunic
Choroid: most of the tunic, posterior, darkly pigmented
Ciliary body
Ciliary Muscles: shape the lens Pupil
Neural Tunic
Retina
Blind Spot
Optic Disc
Optic Nerve (II)
Macula Lutea
Fovea centralis
Behind the pupil
lens (which is held up by…)
suspensory ligaments
Anterior Cavity
Know this term,in front of lens
can be divided between anterior and posterior chamber
Posterior Cavity
Know this term, behind the lens
vitreous humor
Ascending aorta branches into…
right and left coronary arteries
Arteries to head and neck
Divisions of common carotid:
- Internal carotid artery: direct to internal skull
- External carotid: neck and external skull superficial
temporal “artery”
Arteries to the upper limbs
axillary artery: continuation of subclavian after passing first rib brachial artery: continuation of axillary. splits to
- radial (lateral)
- ulnar (both join to)
superficial palmar arch
Arteries of the thorax
From subclavian - internal thoracic (leads to…)
- anterior intercostal
- descending thoracic aorta to…
- posterior intercostal arteries
Branching from descending abdominal aorta
