Anatomy

Front 1

On the pictures shown below, place the appropriate letter:
A. where the brachiocephalic artery arises from the aortic arch
B. where you should place a stethescope to hear the middle lobe of the lung
C. where an indirect inguinal hernia first passes through
D. where an indirect inguinal hernia exits the first inguinal canal to enter the subQ space E. where you should place a stethescope to hear the posterior basal segment of the left lower lobe F. where you should place a stethescope to listen for the mitral valve G. where you should place a stethescope to listen for the pulmonary valve H. where the aorta first takes up a position alongside the vertebral column

Front 2

where are the preganglionic sympathetic cell bodies that have a major influence on heart function

Back 2

intermediolateral column of spinal cord gray matter from T1-T5

Front 3

if you were to surgically destroy the T2-T5 paravertebral ganglia bilaterally, how would this affect innervation and function of the heart?

Back 3

eliminate much, but not all of the pain pathway. eliminate much but not all of sympathetic innervation. heart rate would not increase as greatly during exercise.

Front 4

starting at the heart, trace the arterial supply of the left ventricle in a left coronary dominant heart.

Back 4

left ventricle-->ascending aorta-->left coronary artery --> LAD-->left ventricle

or

left ventricle-->ascending aorta-->left coronary artery --> cirumflex coronary artery -->left ventricle

left ventricle -->ascending aorta-->left coronary artery --> circumflex coronary artery --> Posterior descending-->left ventricle

Front 5

If the mechanism that produces closure of the ductus arteriosis proceeds too far distally and involves the arch of the aorta, the latter may be constricted just distal to the origin of the left subclavian artery
a)trace a route by which blood can reach below umbiculur without passing through the abdominal aorta

b)trace a route by which blood can reach abdominal aorta without passing below umbilicus

Back 5

a) aorta-->brachiocephalic a.--> r. subclavian a-->internal thoracic-->superior epigastric-->inferior epigastric

or aorta -->left subclavian-->internal thoracic a.-->superior epigastric-->inferior epigastric


b) aorta--> brachiocephalic --.>rt. subclavian-->internal thoracic aa-->anterior intercostal aa-->posterior intercostal aa-->thoracic aorta-->abdominal aorta

or
aorta--> left subclavian-->internal thoracic aa-->anterior intercostal aa-->posterior intercostal aa-->thoracic aorta-->abdominal aorta
