heated, speeding electrons are shot at tungsten which knocks outter shell electrons out of orbit.  an electron will have to drop down to take the obrital's place, and energy is expelled in the form of a photon.  this photon is shot at a photographic film
Term
what color is tissue on an xray?  fat?
Definition

gray.

 

gray black

Term
how does an MRI work
Definition
a magnet polarizes the protons of cells and a computer picks up the small resonance they make as they return to their original position
Term
upper left and right divisions of abdomen?  what is their inferior end point?
Definition

R and L hypochondriae

 

the base of the rubs

Term

mid left and right divisions of abdomen?  what is their area?

Definition

R and L flank

 

bottom of ribs to illiac crest

Term
upper middle region of abdomen?
Definition
epigastric
Term
describe the 3 layers of lateral muscle as they relate to rectus abdominus going fro superior to inferior abdomen
Definition
the order is external, internal, and transverse abdominus.  the internal is present on the anterior and posterior (splits) of the rectus abdominus.  as you go inferior to the transtubercle plane (below arcuate line), all three layers pass anteriorly to the rectus abdominus and only the extraperitoneal fat and peritineum are behind the rectus abdominus
Term
umbilical folds on anterior ab wall?
Definition
median, medial, lateral
Term
name the three fossae from medial to lateral in between umbilical folds.
Definition

supravesicle fossa

medial inguinal fossa

lateral inguinal fossa

 

Term
what becomes of the umbilical vein and artery
Definition
round ligament and umbilical medial ligament in adults
Term
a testis travels down the? to the?
Definition

gubnaculum

 

tunica vaginalis (a potential space and visceral area)

Term
what does the round ligament do in women?
Definition
connects uterus to labia
Term
determination of direct or indirect hernias
Definition

if it is medial to inferior epigastic vessels, it is direct.

 

if lateral, indirect

Term
mesentary fxn
Definition
a double layered peritoneal that attaches an INTRAperitoneal organ to the body wall (connects visceral pluera to parietal peritoneaum)
Term
retroperitoneal
Definition

connected and fixed to peritoneum by its mesentary

 

primary retro has been that way since development, while secondary retro happened as a result of crowding (as in the case of the liver bare spot)

Term
intraperitoneal
Definition
suspended within the ab cavity by its mesentary
Term
supracolic vs intracolic compartment
Definition
supracolic means everything superior to the transverse colon (stomach, pancreas, liver), while intracolic is everything held within that square made by the perimeter of the colon
Term
ligaments are named for?
Definition
what they're connecting, usually organ to organ or organ to ab wall.  the hepatogastric and hepatoduodenal ligament are a couple, they also make up the lesser omentum
Term
one fxn of the spleen?
Definition
to recycle RBCs and store some
Term
sympathetic and parasympathetic innervation of foregut
Definition

celiac ganglion -> greater splanchnic nerve

 

anterior and posterior vagal trunks

Term

sympathetic and parasympathetic innervation of midgut

Definition

superior mesenentary ganglion -> lesser splanchnic nerve

 

posterior vagal trunk

Term

 

sympathetic and parasympathetic innervation of hindgut

 

Definition

inferior messentary ganglion -> lumbar splanchnic

 

pelvic splanchnic

Term
what is the portal triad of the liver
Definition
the hepatic artery, portal vein, and bile duct
Term
venous flow through liver
Definition
gut -> portal vein -> sinusoid -> central vein -> hepatic vein -> IVC
Term
why is renal blockage so dangerous?
Definition
because renal vein cannot anastomose
Term
suprarenal glands structural fxn in adults
Definition
no fxn, they are only necessary in embryology when they help to suspend the kidneys
Term
what does the cortex of the adrenal gland secrete?
Definition
corticosteroids and sex hormones
Term

what does the medulla of the adrenal gland secrete?

Definition
epi and norepinepherine
Term
what does the fibrous pericardium protect the heart against?
Definition
over dialation is dystole
Term
describe the muscle fibers in the myocardium
Definition
they take on an alpha helical formation; causes radiated contraction when they contract
Term
what is taken advantage of during a coronary bypass?
Definition
the transverse sinus, cardiac surgeons access great vessels through this and clamp them when performing surgeries
Term
what area of the heart is most suseptible to aneurysm?
Definition
superior to the pericardial sac
Term
Mesonephros becomes?
Definition
Wolffian Duct and tubules and such--In males, gives rise to the efferent ducts, vas deferens, epididymis and seminal vesicles
Term
the roof of the yolk sac becomes our?
Definition
intestines
Term
what first encloses the embryo in the uterus?
Definition
the decidua capsularis
Term

the vitelline vein becomes what?

 

the vitelline artery becomes what?

Definition

the portal vein

 

the celiac trunk and superior and inferior mesenteric arties

Term
