Front 15

which embryonic layer are responsible for molars, premolars and canines

Back 15

teeth are produced by ectoderm (outer most layer)

Front 16

which embryonic layer are responsible for muscles, connective tissue, bone, cartilage?

Back 16

Mesoderm (middle layer between ectoderm and endoderm) will give rise to notochord, muscles, bones, cartilage, bone marrow, and etc

Front 17

which embryonic layer are responsible for lining of larynx, pharynx, lungs ,trachea

Back 17

Endoderm which is inner most layer of the 3 germ layers
gives rise to INNER LINING of lungs, digestive tract, larynx ............

Front 18

difference between osteoblasts and osteoclasts

Back 18

osteoblasts build bone while osteoclasts breaks bone down when the body needs calcium.

Front 19

PTH (parathyroid hormone)

Back 19

stimulate osteoclastic activity

Front 20

calcitonin

Back 20

tones down blood calcium level by decreasing osteoclastic activity.

Front 21

ADH

Back 21

ADH is made by hypothalamus and stored in posterior pituitary gland.
allows the collecting duct of kidney to be more permeable to H2O and therefore can increase blood pressure.

Front 22

Thyroxin

Back 22

increases basal metabolic rate

Front 23

catecholamine

Back 23

example of this class is phenylephrine and norepinephrine (part of fight or flight response)

chromosome turning around 180 degrees

Front 25

what is translocation in chromosomes

Back 25

two non homologous chromosomes interchange genes.

Front 26

aneuploidy less or more chromosomes

Back 26

aneuploidy is just nondisjunction that results in a different number of chromosomes WHETHER LESS OR MORE

Front 27

turner syndrome

Kleifelders syndrome

Back 29

individuals have extra sex chromosomes
XXY
XXXXY
sterile and feminne males

what happens to corpus luteum in the case of fertilization not happening

Back 30

corpus luteum breaks down to corpus Albicans

Front 31

SA node

Back 31

this is the "pace maker" that allows hart to beat!
delivers electrical impulses that allow atrial to contract and push blood into ventricle and allow for heart beat.

Front 32

amphoxious and tunicates

Back 32

amphioxious and tunicates represent chordates that are not vertebrates. they dont lose their notochord but other chordates do.

Front 33

cholecystokinin

Back 33

hormone made by cells of duodenum (1st part of small intestine) stimulates release of bile.

Front 34

chemoreceptors

Back 34

chemoreceptors are specialized structures in walls of arteries.
1. they detect changes in H+ and Co2

Front 35

increase in H+ and Co2 in body would cause

Back 35

increase in breathing rate

Front 36

increase in O2 partial pressure in blood

Back 36

decrease breathing rate.

Front 37

foreman ovale

Back 37

in fetal circulation the foramen ovale is a hole between the right and left part of heart and KEEPS BLOOD AWAY FROM RIGHT VENTRICLE IN ORDER TO ALLOW IT TO BYPASS PULMONARY CIRCULATION

Front 38

ductus arteriosus

Back 38

connection between aorta and pulminary artery TO KEEP BLOOD AWAY FROM PULMORAY CIRCULATION

Front 39

Ductus venosus

Back 39

Ductus venosus moves blood from umbilical cord to inferior vena cava and lets oxygenated blood BYPASS THE LIVER

Front 40

duodenum
what are the first macromolecules to undergo hydrolysis in digestive tract.

Back 40

most enzymatic digestive hydrolysis and processes happen in the small intestine
the first macromolecules to undergo enzymatic hydrolysis in digestive tract is carbohydrates.

Front 41

---------and --------- are carried away from the intestine by blood stream

Back 41

amino acids and sugars are carried away from the intestine by blood stream.

Front 42

where does blood go after small intestine

Back 42

villi------>blood stream---->-liver----->heart----->body
1. villi in the small intestine absorb nutrients via lacteal
2. nutrients go into the bloodstream and then to the LIVER through the HEPATIC PORTAL VESSEL (first access 2 nutrients by body)
3. excess glucose stored in the liver... blood leaves liver and goes to the heart and then transported to the body.

Front 43

Back 44

glycolysis is in the cytosol of mitochondria
kreb cycle is in the matrix of the mito
etc is in the inner mitochondrial membrane
kalvin cycle is in the stroma of chloroplast in plants
