Gross Anatomy Quiz 2 Flashcards
Effect of the ANS on the Heart
sympathetic
Increases: HR Force of contraction BP Respiratory rates
Dilates (relaxes coronary vessels (smooth muscle)
Caval Hiatus Structures
Inferior Vena Cava
How high does the diaphragm go on expiration
6th rib
origins of diaphragm
Sternal : posterior xiphoid process
Costal : internal surfaces of lower costal cartilages 7-12
Lumbar : medial and lateral arcuate ligaments
anterior longitudinal ligament
bodies of vertebrae L1, L2, L3
Innervation of the heart
Afferent Parasympathetic fibers
Vagal cardiac nerves
Function:feedback on blood pressure
Pulmonary valve stenosis
Valve cusps are fused
Conus arteriosus is underdeveloped, producing restriction of right ventricular outflow
Cause hypertrophy of the right ventricle
Produces a fixed split S2 murmur
S2 problem
Horner syndrome
Ptosis (drooping of the superior eyelid)
Pupillary constriction
Sinking in of the eyeball (enophthalmos)
Vasodilation and absence of sweating on the face and neck (anhydrosis),
RCA supplys
R atrium
SA, AV nodes
Posterior Septum
Aortic valve insufficiency
Backrush of blood into the left ventricle
Causes blowing high pitched murmur
Phrenic nerve roots
C3, C4, C5
what provides vascular drainage for left side of thoracic cavity
hemiazygous
How does blood flow into the coronary arterioes
Retrograde flow from aorta
Thet are filled during diastole (resting)
Tachycardia is risk because no rest!
NAV
Nerve (lateral)
Artery
Vein (medial
Ligaments that are part of Lesser omentum
Gastropcephalic ligament
Hepatoduodenal ligament
Lesser omentum
what runs between the anterior scalene and middle scalene
brachial plexus
subclavian artery
subclavian vein
what holds the breast up to the chest wall
suspensory ligament
Lobular Carcinoma In Situ
Believed to be a benign condition that predicts invasive breast cancer in the future
(not necessarily at the same site)
Breast cancer node path
axillary nodes
infra clavicular nodes
supraclavicular nodes
Pulmonary valve incompetence
Valve does not close completely
Results in a backrush of blood into the right ventricle
Causes blowing decrescendo murmur
S2 problem
Anterior interventricular supplys
both ventricles
Anterior septum
What does scalene muscle do
raise ribcage during inspiration
Heart cavity layers
Fibrous pericardium parietal pericardium pericardial cavity epicardium (visceral pericardium) myocardium endocardium
Superior messteric artery supplies
jejunum
cecum
ascending colon
LCA Supplys
L Atrium
L ventricle
AV Bunds
septum
