First of all I suggest you relax and accept that you won't know it all overnight anyway.
Then chunk it... focus on one aspect at a time eg Skeleton (the supporing framework). Mind map it by drawing a skeleton (0r cheat and trace one) Then label all the bones you already know. This now gives you 2 methods of linking new information (the names of bones you don't know yet).
1. the visual of the skeleton
2. the names of known bones next to the unknown.
As you look at the adjoining bone and check out the name, creatively link the name to the appropriate bone. Take your time with it and avoid wanting to finishing the whole skeleton map in one go anyway. You could divide it into 5 regions to be learnt over 5 study sessions. E.g Trunk and arms, Pelvis and legs, Head, Hands and Feet.
How to remember the names? Play with them E.g.
Scapula - I come up with an image of a mad man (it could be a clown, that would be different) waving a shoulder blade saying 'Scalp ya later!'
Sacrum - easy a 'sack of rum' rum in a sack you ask how is that possible? Easy in your imagination (ok it still leaks in mine) 
Thorax - the god Thor using his ax to hack that part of the body.
Humerus - well thats the funny bone anyway, reminds me of one of my teachers who knocked his arm and said, "oww 'me' funny bone" so the class laugh (well it was bad English afterall) and he got miffed and said "It's not funny", while stamping his foot.
The better you link your cue with the name and the image of the bone the easier it becomes to remember. So take your time with it and remember it's definately something you don't try to learn all at once. So break it down into blocks.
