ID the pinned structure
Lingula
ID the pinned structure
Pectoralis Minor
ID the pinned structure; T/F: this is anterior
Vertebral Body; true
Name the pinned structure
Azygous Vein
ID the pinned structure; T/F: This is a fetal remnant structure
Ligamentum Arteriosum; True, in fetal life, it is the Ductus Arteriosus
ID the pinned structure; does this contain axons or neuronal cell bodies
Lateral white column; contains axons
ID the pinned structure; What's the innervation
Levator scapula; dorsal scapular n
ID the pinned structure
Lamina
Classify the following ribs:
2nd
8th
12th
2nd-true rib
8th-false rib
12th-false/floating rib
ID the pinned structure; give the origin of the pinned structure
Circumflex A.; origin is LCA
ID the pinned structure; T/F: the left lung has three of these
Lobar bronchi; false; the left lung has only 2 of these
ID the pinned structure; T/F: these muscles make contact with the vertebrae
Internal intercostals; false, they terminate before they reach the vertebrae
ID the pinned structure; what does this pinned structure help to form
Superior vertebral notch; the inferior border of the intervertebral foramen
ID the pinned structure; give the origin; T/F: the equivalent vessel on the left side of the body shares the same origin
R. Common Carotid; origin is the brachiocephalic; false; the left common carotid originates from the arch of the aorta
ID the pinned structure; does the structure has deoxygenated or oxygenated blood
ID the pinned structure; t/f: this contains motor info
Ventral rootlets; t; ventral rootlets carry motor information
ID the pinned structure; T/F: this is an erector spinae muscle
Longissimus Capitis; true
Classify the vertebrae; how many other vertebrae in the body exhibit this morphology
Lumbar; there are 5 lumbar vertebrae, so 4 other vertbrae in the body look like this
ID the pinned structure; at what level does this occur; what else occurs at this vertebral level
Carina; occurs at the level of T4; the innervation of the nipples and the sternal angle occur here
Name the layers of the heart deep to superficial
Endocardium-->myocardium---<visceral pericardium/epicardium---->parietal pericardium---->fibrous pericardium
At what vertebral levels do the aorta, IVC, and esophagus cross the diaphragm
IVC: T8
Esophagus: T10
Aorta: T12
ID the pinned structures; do these muscles share the same innervation; if so, name the innervation; if not, name the innervation of each muscle
Pinned Structure 1: Teres Minor
Pinned Structure 2: Infraspinatus
False; TM innervation is axillary, while IS is innervated by the suprascapular n
Name the pinned structure; give all of the contents
Vertebral Column; Spinal cord, CSF, Meninges, spinal nerve roots/rootlets, adipose, vessels
ID both pinned structures; T/F, they have the same origin in a left dominant heart
Pin 1: R. Marginal Artery
Pin 2: Post. IV Artery
False, in a left dominant heart, the origin of the Post. IV Artery is the circumflex, while the R. Marginal Artery's origin is always the RCA
