Verizon [17]

Answer:

The options

1

Have dilute urine."

2

Be unable to urinate."

3

Produce dark red urine."

4

Experience some burning on urination."

The CORRECT ANSWER IS 4

4

Experience some burning on urination."

Explanation:

Due to the trauma affecting the mucous membranes of the urinary tract, burning on urination is a more likely response, this sensation gets to reduce with time. This will stop the urine from further dilution once the frequent continuous bladder irrigation is stoped and removed. Although, the urine may show a slight pink tinge which results from the trauma after the surgery and the effect of the catheter that is noticed. A difficulty to urinate won't be felt except the indwelling catheter is removed earlier than it should expected and edema still occurs in the urethra. Production of dark red urine is an indicative factor for hemorrhage, which ought not to be seen.

These cellular structures are utilized in strong involuntary muscle contractions and transmission of electrical impulses. ______
sertanlavr [38]

Answer:

The best answer to the question: These cellular structures are utilized in strong involuntary muscle contractions and transmission of electrical impulses, would be: T-Tubules.

Explanation:

In both skeletal and cardiac muscle, not smooth muscle, because of the way that the muscle fibers are conformed into tight bundles of sarcomeres (skeletal muscle) and myocardiocytes (cardiac muscle), there is a need for a series of structures that will ensure that when there is a stimulus from the nervous systems, these stimulus will propagate to all the cells in the fibers, and not just one.

Aside from counting with a neuromuscular motor plate, which will receive the neurotransmitter from the nerve endings and produce the appropriate reactions, as well as propagate that reaction to all the cells that are being stimulated, muscle fibers also have a structure known as T-Tubules. T-Tubules are formations much like roadways of cell plasma membrane that connect not just one, but all the cells within a muscle fiber so that once a stimulus comes, all the cells will initiate the process of calcium release and action potential propagation. These T-Tubules will ensure that electrical impulses reach all muscle cells and that all cells react at the same time as needed.
