BIOC21H3 Lecture : lab on smooth muscle

Explain the structural differences of the contractile units inskeletal, cardiac, and smooth muscle. Why would calcium channelblocking hypertension drug have an effect on blood vessels andcardiac muscle but not affect coordination or the ability tooperate skeletal muscle tasks?

How would you expect cardiac muscle tissue to look different than the skeletal muscle tissue you observed? How would you expect smooth muscle tissue to look different than the skeletal muscle tissue you observed

Give 2 differences in EC coupling in skeletal vs. cardiac muscleand 2 differences in EC coupling in skeletal vs. smooth muscle.
