Lecture exam on integumentary system, skeletal system, muscle system.

Need to know all of the chemical processes needed for muscle contraction...

I normally don't have trouble with classes, but this one is kicking my butt.  I don't know what I'm doing wrong, but labelling parts of things (like the parts of a long bone, parts of a sarcolemma (or whatever), parts of a muscle (all of the little thingies inside), parts of the layers of skin, yada, yada...

And I sign up for next semesters classes...I need to choose between getting back on the math track (needed to transfer) or retaking Spanish 101.

And I'm definately taking a Dreamweaver course.
