Please clear my confusion

Members don't see this ad.

1. B cells are developed in the bone marrow, but mature in the spleen? (or was destroyer wrong and meant rbc)

2. T-cells are made in the thymus and stored where?

3. "Egg cell will contain 23 chromosomes and 23 chromatids" -Destroyer #158. ..why! aren't there 2 chromatids per chromosome? so shouldn't it be 46 chromatids??

4. So if that's the case, a diploid cell will have 46 chromosomes..and how many chromatids then?

being home on a friday nite confused sucks.

1. B cells are developed in the bone marrow, but mature in the spleen? (or was destroyer wrong and meant rbc) kinda werid, but yes its true. B cells are produced in the bone marrow, but then they mature to B lymphocytes in the spleen. just like T cells originate in bone marrow, then mature to T lymphocyte in thymus.

2. T-cells are made in the thymus and stored where? thymus or lymph organs

3. "Egg cell will contain 23 chromosomes and 23 chromatids" -Destroyer #158. ..why! aren't there 2 chromatids per chromosome? so shouldn't it be 46 chromatids??i'm thinking since its an egg cell, its haploid, which means 1 chromosome is also 1 chromatid, so 23 chromosomes in a haploid cell will have 23 chromatids....not sure

4. So if that's the case, a diploid cell will have 46 chromosomes..and how many chromatids then?these should have 92 chromatids, two for each chromosome

being home on a friday nite confused sucks.

hope it helps..

Developed in the bone marrow and matured in the appendix sacculus rotundes or something like that... then they go into the spleen and get matured there and become B lymphocytes

2. T-cells are made in the thymus and stored where?

okay I know they are developed and matured in the Thymus. I don't know where they are stored (there are many diff types of Tcells) im guessing they are all around

3. "Egg cell will contain 23 chromosomes and 23 chromatids" -Destroyer #158. ..why! aren't there 2 chromatids per chromosome? so shouldn't it be 46 chromatids??

well since "N" refers to a multiple of 23 and the egg is N it has 23 chromosomes and 23 chromatids...

4. So if that's the case, a diploid cell will have 46 chromosomes..and how many chromatids then?

92 chromatids ...

lol, don't do it, it's a waste of time...not that u couldn't have guessed that lol.

happy birthday to the previous post btw.. just for that, u will get 30's all across the board!!!!

and u know the SAD thing? i overlook small things but this is overshooting..

Agranulocytes are one of the two types of leukocytes, which include Monocytes and lymphocytes..

i had no idea that t-cells and b-cells were lymphocytes..i always just called them t-cells and b-cells.

THANK U SDN!!! lol. no seirously!!!

this should boost up ur DAT confience 10000X.!

i wanna try doing angle ranking drunk...

LOL

LOL

lol, well i think u'll do phenomenal cuz i do SO bad sober.

alrite kids..back to studying! don't get any ideas now DDS man.

BOTH T CELLS AND B CELLS ARE MADE IN BONE MARROW.....T CELLS ARE NOT MADE IN THYMUS....they only mature there....thts where they get educated (mature)...they are not made there nor stored

Kush is right...

My bad...

Made in bone marrow/matured in thymus

the only reason i know abt this crap is cuz i took immunology....i know way too much for this section....and there is prob ONLY 1 question abt it...so dont worry if u dont know something in immunology

if you ask people who have taken the exam... they will confirm with you that this is NOT so true anymore
im talking about the number of questions from each section

ps. im glad i didnt take immunology

 

[Mrbubbles]

to sum up my confusion:

B cells: develop in the bone marrow, mature in spleen
Tcells: develop in bone marrow, mature in the thymus

but the question is..what COLOR bone marrow? and i DO know this, just testing you SDNers

drinking + angle ranking = Get High Test Scores (G=H-TS)

=) there's one more for ya.
