Answer:

The correct option is C. Motor neuron does not fire action potentials

Explanation:

During contraction, the motor nerve passes down an action potential. A neuromuscular junction is formed by the motor neuron which stimulates the entry of calcium ions. The calcium ions bind to structures called as troponin which stimulates the binding of the filaments, actin and myosin. The filaments begin to contract by using ATP.

During relaxation, the action potential is stopped. Calcium is taken back into the sarcoplasmic reticulum. As a result, actin and myosin filaments do not link and hence, the contraction is stopped.

When health care teams solve problems, it is important that in the final stage, all team members _____. Have a say in the goals
Nadusha1986 [10]

Answer:

The correct answer is ''understand their roles''

Explanation:

Teamwork in a health team is considered important as a way of dividing responsibilities, correctly attending to the roles in a work team and the functions of the figures that intervene in the teamwork in order to achieve recovery the health of the patient more quickly. Each of the health professionals in this group or team must have a role to fulfill the desired objective; the team is a group of individuals who cooperate to perform a particular routine activity; there is a link of reciprocal dependency that unites the members of the same team with the others. This vision is justified, for each professional to have a different perception of the situation, it is the “union” of the different perceptions that facilitates the understanding of the whole, allowing a glimpse of the patient as a whole. Usually, the general doctor assumes the role of knowing the patient in depth, in order to be able to guide on health problems and decide together with him or her the treatments and objectives to be achieved.
