Question

Your biceps muscle is attached to the top of your humerus and to the end of your radius, near your elbow. What would happen if the biceps were attached to the top and bottom of your humerus instead?

Answer 1

A. You would be able to pull your forearm toward your shoulder with more force.
B. You would not be able to pull your forearm up toward your shoulder.
C. Your humerus would lengthen and shorten each time your biceps contracted.
D. Your triceps muscle would make your arm bend backward when it contracted.

Answer 2

Hi everyone. I'm doing a Biology worksheet. I ran into this question and I'm a little thrown off by it. I'm thinking it's B...

Answer 3

B, Your bones are stopping you from letting your arm bend backward. You can't push forward too so that's B.

Answer 4

Simple biomechanics logic. It has to be B. The bones aren't changing shape, C is crazy lol. A is irrelevant, as your elbow forms a lever, 3rd class I think. With the effort on the wrong side of the fulcrum and you get nothing happening, just a dangling load.

Answer 5

yeah! nice Agentx5! High Five!

Answer 6

You can make this happen by slashing somebody's tendons that attach this muscle. A disarming technique they used to train samurai to do in Japan during the feudal era. (the modern equivalent of tazing somebody I guess)

Answer 7

And that is called more than you wanted to know :P

Answer 8

yeah, you can do that too by breaking someone's bones!

Answer 9

Rose must be very happy to see all our contributions!

Answer 10

Major structural bones such as the humerus are not as easy to break as you might think. A katana is very sharp.

Answer 11

yeah, but it's still breakable

Answer 12

True. ^_^ I'll not debate that

Answer 13
