Your Venn diagram will have three circles – one for each muscle tissue type. Your diagram should address (at a minimum) the following:A minimum of 12 structural and functional characteristics (at least 4 for each muscle tissue type). At least one of those must be shared between all three muscle tissue types. All identified structural and functional characteristics must be clearly identified and must be placed in the proper location within the Venn diagram. For example: you might choose the characteristic of “striated appearance”. Striated appearance would be properly placed into the overlap area between skeletal and cardiac muscle. “Lacking striations” would properly be placed into the smooth muscle only area. That would count for 2 of the required 12 characteristics.
