Where do you find skeletal muscle? Describe fibers.

Found in: Attached to bones and skin. Description: Large, multinucleated, cylindrical cells with striation.

61

Where do you find cardiac muscle? Describe fibers.

Found in: wall of heart. Description: smaller, branching cells, with one or two centrally located nuclei per cell. Exhibit striations , and have intercalated discs (dark bands where cardiac muscle cells connect end to end).

62

Where do you find smooth muscle? Describe fibers.

Found in:

-Walls of digestive tract organs

-walls of arteries and veins

-walls of ureters, urinary bladder, and urethra

-intrinsic muscles of eye

Description: small, spindle-shaped (tapered at both ends) cells that are uninucleated and nonstriated.
