I am in a bio class, and we dissected a chicken wing...for about 10 minutes...didnt give us time for much...the teacher is very strict, and could care less that we didnt have time to really look at the diffenent things in the wing...i have a few questions...the white shiny covering of the joint surfaces in the wing...is that articular cartilage or no? Also, what is the fluid that lubricates the joint surfaces, and what is the function? please...if you know anything else about this it would really help alot...thank you so much

I am trying to hook up 20 bouncing tiggers. All the same toy. Each has 4@ 1.5AA batteries. THey have Duracell Alkaline in them. I tried a battery replacement for a ps1 game unit but it is only 4.5 vDc and for some reason you had to push the trigger (hand) twice to get it to activate. The toy Bounces up and down and sings the tiger song for about 10 seconds. 6 volts per tigger. Will one regulated power supply do or should I buy more than one. Thank you, Kim
