•Skeletal muscle tissue
Description – Long, cylindrical, multinucleate cells; obvious striations o Consist flexible muscle fibers that is important for our movement. The fibers contract or tighten that allows muscle to move our bones
Function – Voluntary movement; locomotion; manipulation of the environment; facial expressions; voluntary control. Maintains body posture and protecting joints
Location – In skeletal muscles attached to bones or occasionally to skin

•Cardiac muscle tissue
Description – Branching; striated; generally, uninucleate cells that interdigitate at specialized junctions (intercalated discs). Get strength and flexibility from its interconnected cardiac muscle cells/fibers o Contains one nucleus but some has two o Striation occurs due to alternating filaments called the actin and myosin
Function – As it contracts, it propels blood into the circulation, involuntary control. Vital for pumping blood throughout circulatory system. It also resists fatigue
Location – The walls of the heart

•Smooth muscle tissue
Description – Spindle-shaped cells with central nuclei; cells arranged closely to form sheets; no striations 20-200 micrometer height. Bundles do not run parallel but consist in a complex system o Present throughout our body
Function – Propels substances or objects (foodstuff, urine, a baby) along internal passageways, involuntary control
Location – Mostly in the walls of hollow organs o Helps in digestion and nutrient collection. Present in urinary system that helps in removing toxin and balance electrolyte
