Question

muscular system

a) indicate one (1) other organ system with which the assigned system    

      operates closely for a similar or combined function;

b) select one (1) major disorder (not covered in class discussion) of the

      assigned system, giving c1) cause, c2) organs affected, c3) prognosis

       and c4) treatment.

Answer 1

In the musculoskeletal system, the muscular and skeletal systems work together to support and move the body. The bones of the skeletal system serve to protect the body's organs, support the weight of the body, and give the body shape.

Smooth muscle fibers are located in walls of hollow visceral organs, except the heart, appear spindle-shaped, and are also under involuntary control. Skeletal muscle fibers occur in muscles which are attached to the skeleton. They are striated in appearance and are under voluntary control

In summary, skeletal muscles are organs that are directly or indirectly attached to bone. Skeletal muscles serve a variety of functions including support and movement and homeostasis. Skeletal muscle contraction can result in muscle shortening and thus movement of the bone to which it is attached.
