Characterized as one nucleus per cell, cells are branched and striated. Smooth: found in hollow organs such as blood vessels, ureters, bladder, etc. characterized by having a single nucleus per cell, spindle shapes being thicker in the middle and tapered at ends and these cells don"t have any striations. Neurons: large nerve cells that transmit nerve impulses in the nervous system. Neurons have a cell body which is the main cell with organelles are. Neurons have one long axon and typically more than one shorter dendrite.
