haha no idea on these

http://www.hsc.csu.edu.au/biology/options/communication/2955/CommPart7.html#3

Brain parts.


Here is my quick summary of insects/fish/mammals


Production of sound

Insects> fiction on hind legs or veins together on forewings
Bats> ultrasounds from larynx
Fish> vibrate swim bladder

Detection of sound

Insects> Tympanic membranes (mechano receptors)
Mammals>Cochlea/hair cells
Fish> Lateral line system(neuromasts>brain), internal ear (semi circular canals/labrinyth/ Sound goes through skeleton)

The HSC CSU online communication section is surprisingly detailed I think, so check that out.

oh, nice

are we required to describe the function of the three?

wow, you're right

im just going to use this to study for the next hour, hehe

it looks detailed, ta

 

[dolbinau]

You have to compare them.

 

[Takuto]

okie

The function and distribution of rods and cones in humans?


and what colours does the rhodopsin pigment detect

 

[alez]

rods-b&w, low light, all over retina
cones-colour, conc in fovea, only work well in bright light
rhodopsin-pigment in rods?

ok so visual centre is at front of brain?
fuck
the notes from our dissection have everything all over the place and we had it at the back... oops....

 

[dolbinau]

The visual area should be at the back.

That diagram is a little misleading. Probably 'cause the cerebellum is missing. (Unless it's completely wrong and it's meant to be on the other side)

 

[alez]

ok thanks
im so fucked for this

 

[dolbinau]

wikipedia visual cortex, excel book always say back I'm 100% sure that's right. The diagram of the brain on HSC CSU online is just missing the cerebellum I think so it looks like it is the wrong way around.

 

[Takuto]

hmm where to find function of medulla oblongata, cerebrum and cerebellum

cant seem to find lol

 

[alez]

forgot bout function... do we need to know that?
cerebellum is skill memory
cerbrum is almost everything, like thought, interpretation of signals and whatever
and medulla is autonomic functions like breathing, blood pressure and relays signals from brain to spinal cord

 

[dolbinau]

Medulla Oblongata = Basic functions, breathing, blood pressure

Cerebrum = Everything else basically, thought, speech, visual etc..

Cerebellum = Muscle movement/balance etc. - Important if we get a question on co-ordination of nerves and stuff (you can also use other functions too like sight but still)

Going to school1 Good Luk!

 

[Takuto]

good luck to you both too!! thanks for all the help!

 

[syriangabsta]

This thread turned out to be HUGE...

oh well, Goodbye to the biology forum ^^. see ya in like never maybe


P.S. you were my best subject

 

[dolbinau]

Let's all go to the Physics forum now!! Start another nextttttttttt*t*

But it probably won't be active until after the round of maths exams coming up. (WEll after SOR for me on friday)

 

[dolbinau]

Yes, it is. "No?" I don't understand.

 

[16kk69potter]

?????huh?????

Exacly What Is This Topic About???????

I Don't Suppose Any Of You Are Doing Year 11 Bio?????

And Would Be Any Help Doing Quadrate Reports I Am So Screw Right Now

Oh Yeah And About The Neeeexxt Topic ... I .... Uh ..... Totally Agree LOL

 

[16kk69potter]

Oh Yeah And Could Define (In Detail) Succession In Mangroves, Sand Dunes And Rocky Shores

Cause Yeah .... :jaw: LOL

That Would Be A Big Help

 

[Mongoz]

ohhhhhhh
plz stop about talkin biology
itz ovaaaa 4 good
this forum was a GIGANTIC success
bUUUUUUUUUUt
neva again will i visit
BYEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
:wave:
