Divide numbers in a cell. To do this task, use the / (forward slash) arithmetic operator. For example, if you type =10/5 in a cell, the cell displays 2. Important Be sure to type an equal sign (=) in the cell before you type the numbers and the / operator; otherwise, Excel will interpret what you type as a date.
Muscle has four major functional characteristics: contractility, excitability, extensibility, and elasticity. Contractility refers to the capacity of muscle to contract or shorten forcefully.
Heart muscle exhibits many structural and functional characteristics intermediate between those of skeletal and smooth muscle. Like skeletal muscle, cardiac muscle contractions are strong, and utilise a great deal of energy. Like some smooth muscle, cardiac muscle can contract without nervous stimulation (i.e. it is myogenic) and this enables the heart to be transplanted.
