Answer:
1. spontaneously
2. resting potential
3. action potentials
4. pacemaker potentials
5. K+
6. Na+
7. into
8. Ca+
Explanation:
Pacemaker cells (also known as sinoatrial node cells) are cells that generate rhythmic impulses and set the pace for blood pumping in the heart. These cells have the ability to rhythmically depolarize and initiate action potentials. In pacemaker cells, Ca2+ and Na+ levels are higher in the extracellular environment, while K+ concentration is higher intracellularly. The pacemaker action potentials have three phases: 1-depolarization, where membrane potential reaches -40 mV and voltage-gated Ca2+ channels open, 2-repolarization, where voltage-gated Ca2+ channels close and voltage-gated K+ channels open, and finally 3-gradual depolarization, which is caused by the slow influx of Na+ ions.
Assuming that Kai is a child, telling him about his own diagnosis requires some thinking about what age is ideal for Kai to effectively understand his condition and prognosis.
If Kai is a child with special needs, for example, the prognosis must first be made to the parents, who must make the ethical decision on whether or not it is necessary for him to know in advance about his condition.
If parents decide that the child should know about their condition and prognosis, if these interfere directly in their routine and activities, it is necessary that the child has a professional and psychological apparatus to be able to assimilate their condition in the best way.
It is necessary that parents are prepared to deal with the needs of having a special child, adapting, giving all the medical and emotional support necessary for their complete cognitive development and quality of life.
