• Mitosis

• - is the process by which a eukaryotic cell separates the chromosomes in its
• cell nucleus into two identical sets in two nuclei.

outside cell activity

• groups of cells

• working together.

• 1. Muscle

• – provides movement both voluntary and involuntary.

• a. Skeletal

• c. Smooth

• Muscle (Viscera) – involuntary, nonstriated, spindle shaped and is found in
• blood vessels & the GI tract.

• – membranes or linings.

• a. Serous

• b. Synovial

• – lubricates dyarthrodial joints

• c. Mucous
