Muscle Tissue
1. How is muscle tissue categorized? Muscle tissue is categorized by its shape, the number of nuclei, and the mechanism of stimulation.
2. a. Click the Smooth Muscle Tissue. Identify each of the following:
Nucleus-----
Smooth Fiber Muscle------------------
b. Describe smooth muscle control (voluntary or involuntary). Involuntary
c. Name some smooth muscle functions (click the “Tissue Locations” button). Smooth muscle is found within the walls of all hollow or tubular organs of the digestive, respiratory, urinary, and reproductive tracts.
3. Click the “Cardiac Muscle Tissue.” a. Identify each of the following: • Intercalated Disc ---------------------------------------------------------------------------- • Nucleus ------------------------------------------------------------------------- • Cardiac muscle fiber (cell)------------------------ • Striations-------------------------------------- • Gap junctions-----------------------------------------------------
b. Describe cardiac tissue control (voluntary or involuntary). Involuntary
c. Name cardiac tissue function (click the “Tissue Locations” button). Found in the wall of the heart in a muscular layer called the myocardium.
4. Click the “Skeletal Tissue.” a. Identify each of the following.
Skeletal muscle fiber--------------
Nucleus-----
Striations-----------------------------------
b. Describe control of skeletal muscle contractions (voluntary or involuntary). Voluntary
c. Describe skeletal muscle functions (click the “Tissue Location” button).
Helps maintain posture, Moves skeletal bones in the face, pharynx, larynx, and diaphragm.
