CanColl May12 MCQ RegA 2 B

QuestionAnswer
cranial bones (8) frontal, parietal(2), temporal(2), occipital, sphenoid, ethmoid
paranasal sinuses FEMS - frontal, ethmoid, maxillary, sphenoid
mm's of mastication masseter - elevate + retract temporalis - elevate medial pterygoid - elevate + protract lateral pterygoid - depress
sella turcica turkish saddle - cradle for the pituitary gland
sutures - between frontal and two parietal bones coronal
sutures - between 2 parietal and occipital bones lambdoid
sutures - between 2 parietal bones sagital
what is the function of the pterygoid process forms attacments for the mandibular mm/s
where is the pterygoid process found? part of the sphenoid bone
what forms the zygomatic arch Zygomatic process of the temporal bone and the temporal process of the zygomatic bone
Of 14 facial bones - only two do not come in pairs? mandible and vomer
describe mandible largest and strongest facial bone - does not articulate with any facial bones - only articulates with temporal bone(s)
what is the area of the thoracic cavity where the heart is found called the mediastinum
apex of the heart pointed end - bottom -
base of heart broad portion - top
where does the coronary sinus empty into Right atrium
where does the middle coronary vein drain into coronary sinus
what type of fluid is found in the pericardial cavity serous fluid
what are the layers of the heart wall epicardium (outer), myocardium (middle), endocardium (innermost)
what does the deep coronay sulcus separate? atria and ventricles - goes around the equator of the heart
what drains into the right atrium superior vena cava, inferior vena cava, coronary sinus
what drains into the left atrium pulmonary vein (oxygenated blood)
where is the mitral valve located L - AV valve
chorae tendinae prevent prolapse of AV valves - both sides
temporary blood vessel in fetal life ductus arteriosus - shunts blood from pulmonary trunk into the aorta (lungs are not functioning yet)
what is called the pacemaker of the heart SA node - sinoatrial node
what is it called if there is anther area starting action potentials in the heart? ectopic pacemaker
which valve is located between the left ventricle and the aorta aortic valve aka aortic semilunar valve
what vessels carry deoxygenated blood? pulmonary artery, superior vena cava, inferior vena cava and coronary sinus
Progression of secretions from Liver, Gall Bladder and pancreas to the small intestine A from the liver - the left and right hapatic ducts joint to form the common hepatic duct.
Progression of secretions from Liver, Gall Bladder and pancreas to the small intestine b secretions from the gallbladder flow along the cystic duct. The cystic duct joins the common hepatic duct - and forms the common bile duct.
Progression of secretions from Liver, Gall Bladder and pancreas to the small intestine c secretions from the pancreas flow thru the Duct of Wirsung aka the Major Pancreatic Duct. This joins the common bile duct.
Progression of secretions from Liver, Gall Bladder and pancreas to the small intestine d The pancreas has an alternate duct - the Duct of Santorini - that flows from the Duct of Wirsung - directly to the small intestine without joining the common bile duct.
Progression of secretions from Liver, Gall Bladder and pancreas to the small intestine e the common bile duct proceeds thru the ampulla of Vater, the sphinctor of ODDI aka the choledochal sphincter and into the duodenum
what is another name for the mitral valve the biscuspid valve
muscles that move the mandible masseter, temporalis and medial pterygoid - all elevate mandible (closing the mouth) - only the lateral pterygoid depresses the mandible (opening the moutn)
layers of the heart wall epicardium - thin transparent outer layer myocardium - muscular middle layer endocardium - thin, smooth inner layer
which layer of the heart is the thickest the myocardium (smooth muscle) makes up the bulk of the heart and is responsible for the pumping action
Stomach: cardia surrounds superior opening
stomach: fundus superior rounded portion of stomach
stomach: body large central portion
stomach: pyloris connects to the duodenum
stomach: rugae large folds in the mucosa
stomach: pyloric sphinctor opening to the duodenum
stomach: lessor / greater curvature lessor - inside , greater - outside curve
gastric juice contains HCL acid, pepsin, intrinic factor and gastric lipase
HCL kills bacteria and denatures protein
pepsin begins digestion of proteins
intrinsic factor aid in absorption of Vit B12
gastric lipase aids in digestion of tryglycerides
stomach: chief cells secrete pepsinogen and gastric lipase
stomach: parietal cells secrete HCL acid and intrinsic factor
function of kidneys remove metabolic waste, body fluid level regulation, H2O/electrolyte balance, production of hormones and enzymes, PH balance
what effect does antidiuretic hormone ADH have on the kidneys increases reabsorption of water - less urine output
thirst mechanism 4 steps dehydration, stimulates thirst mechanism, increases fluid intake, restoration
HOw does the dehydration step affect the body dec saliva, inc blood osmotic pressure, dec blood volume
What effect does aldosterone have on the kidneys inc angiotensin II - decreases fluid loss in urine
oocytes prospective eggs
ova eggs
Gonadotropin releasing hormone aka GnRH aka Guns & Roses controls ovarian and uterine cycles
GnRH is secreted by: the hypothalmus
GnRH stimulates the release of: follicle stimulating hormone FSH - and - leutinizing hormone LH
FSH - stimulates follicular growth adn secretion of estrogens by the follicles
LH - stimulates further development of ovarian follicles, brings about ovulation - stimulates production of estrogens, progesterone, relaxin and inhibin
LH & FSH are produced by Anterior pituitary gland
estrogens, progesterone, relaxin and inhibin are produced by the corpus luteum - within uterus
oxytocin is released by the posterior pituitary gland
oxytocin functions to eject milk in reponse to the sucking on the nipple
milk production is stimulated by prolactin
