Answer:
a. branched- cardiac muscle cells
b. spindle shaped- smooth muscle cells
Step-by-step explanation:
Muscle cells are termed as myocytes. These are the cells that are made up of muscle tissues. These cells help in the movement and locomotion of the body.
In the human body, there are three types of muscle cells, skeletal, cardiac, and smooth. The skeletal muscle cells are cylindrical in shape. The cardiac muscle cells are rectangular in shape and have branching fibers. The smooth muscle cells are spindle-shaped.
