1. A model for anatomic training, comprising: a visibly clear thermoplastic elastomer matrix formed with at least one contoured surface, the contoured surface simulating at least a portion of a human body, the visibly clear thermoplastic elastomer matrix providing visible needle tracks upon needle penetration, wherein the needle tracks are fused closed upon heating the thermoplastic elastomer matrix such that the needle tracks are no longer visible in the thermoplastic elastomer matrix; and a skeletal structure embedded within the visibly clear thermoplastic elastomer matrix at the same location, relative to the contoured surface, as the corresponding skeletal structure is located in a human body, the skeletal structure producing a fluoroscopic image representative of human bone corresponding to the skeletal structure.
