A cow.....
Forelimbs
I didn't actually know this until a few months ago when a biologist friend corrected me so I can't take all the credit for stating most of those in this thread are WRONG...
Wikipedia said:
Can probably find a better source than Wikipedia easier than scratching my own arse, if you really need one. Excessively pedantic restrictions on terminology are not necessary in every-day conversation.
Just because it's in common usage doesn't mean it's right.

Actually you'll find that most words you speak daily became 'right' due to common usage.

Nope...
As all mammals are pretty much evolved from the same few species if any there are only likely to be a couple that actually do have 4 legs. All else appear to have shoulder bones at the front and pelvis at the back.
But then t says "or"...
Last time I checked my legs didn't have elbows and certainly weren't attached to my shoulders...
But why does that make them arms over legs.
Does a leg have to have a knee and does an arm have to have an elbow. Surly the definition isn't on structure but what it's main use is.
Don't horses hind legs have "elbows".
So are they infact arms, but then it's a pelvis not a shoulder.
So how does horse fit into this.
And on the other end, how's elephant fit into your classification. Shoulder, no elbow.

Also interestingly the bit everyone thinks of of a knee on the hind limb of a horse is actually (essentially) their ankle... The knee equivalent is right up the top.

I don't know the specifics as to why but looking in a bit of detail at the skeletal structures of all the animals mentioned (including humans in this) it's fairly easy to see why animals front limbs are not actually legs. The back and front limbs are significantly different in the way they attach to the body and the makeup of the actual limb itself.
