Human anatomy!!! Help. Bones/Muscles?

Question

1. Which of the following is NOT true of phalanges of the hand?

A) They are the bones of the fingers and thumb

B) They are numbered I-V like the metacarpals.

C) There are 3 phalagnes in each digit

D) The proximal row articulates with the metacarpals.

E) The total number of phalanges in one hand is 14

2. The gastrocnemius

A) is the prominent, superficial muscle of the calf

B) everts the foot

C) dorsiflexes the foot

D) extends the knee

E) all of these are correct

Answer 1

no 1 is C (the fingers have 3 phalanges each and the thumb has 2)

no 2 is A. E cant be right cos gastrocnemius plantar flexes the foot not dorsiflexes. all the muscles at the back of the leg i.e. calf plantar flex (which makes sense cos if they contract the foot goes downwards) whereas the muscles on the front of the leg and the side would dorsiflex which also makes sense cos if they contract the foot goes upwards.

Answer 2

1. C-- there are three phalanges in all fingers but the thumb. Look at your fingers and see. :)  (the girl above me is wrong-- she didn't read the question and answered which is TRUE not FALSE!)

2. E-- it's basically the calf muscle and controls pretty much all the lower half of the leg. Plus, it's the muscle that sticks out (is superficial) when it's buff! You can check here: http://en.wikipedia.org/wiki/Gastrocnemi...

hehe, good luck!
