Acetylcholine and adenosine are neurotransmitters that can modulate the activity of cardiac pacemaker cells.

Specifically, these neurotransmitters can affect the pacemaker potential of these cells, which is responsible for their automatic firing and generation of action potentials.

Acetylcholine is released by the parasympathetic nervous system and acts through muscarinic receptors to decrease heart rate. It does so by opening potassium channels, hyperpolarizing the pacemaker cells, and slowing down the rate of depolarization during Phase 4 of the pacemaker potential. This slows the firing rate of the pacemaker cells, decreasing heart rate.

Adenosine is an endogenous nucleoside that is released during metabolic stress, such as hypoxia or ischemia. It acts through adenosine receptors to decrease heart rate and increase coronary blood flow. Adenosine exerts its effects on the pacemaker cells by opening potassium channels, which hyperpolarizes the cells and slows the rate of depolarization during Phase 4. This decreases the firing rate of the pacemaker cells and subsequently decreases heart rate.

Explanation:

The glomerulus and the glomerular capsule form the filtration membrane in the nephron.

Vascular endothelial growth factor (VEGF) is stimulated in tumor mass by hypoxia-inducible factor (HIF).

Hypoxia (low oxygen levels) within the tumor activates HIF, which then induces the expression of VEGF. VEGF promotes the formation of new blood vessels (angiogenesis) by binding to receptors on the surface of endothelial cells lining existing blood vessels, leading to their proliferation and migration towards the tumor. This process supplies the tumor with the necessary nutrients and oxygen for its continued growth and survival.

Cardiac muscle action potentials are unique compared to action potentials in other types of muscle or nerve cells.

The cardiac action potential has five phases (0 to 4) and is characterized by a prolonged plateau phase (Phase 2). The plateau phase is unique to cardiac muscle action potentials and is responsible for the extended refractory period of the cardiac muscle.

The plateau phase is maintained by the influx of calcium ions through L-type calcium channels (also known as dihydropyridine receptors) and the efflux of potassium ions through delayed rectifier potassium channels. The L-type calcium channels are activated during Phase 0 of the action potential and remain open during the plateau phase, allowing a sustained influx of calcium ions into the cell. This influx of calcium ions triggers the release of additional calcium ions from the sarcoplasmic reticulum, which activates the contractile machinery and leads to muscle contraction.

The lifetime risk of induced hereditary effect per Sievert is a measure of the probability of a hereditary mutation occurring in an individual's offspring as a result of exposure to ionizing radiation. This risk is estimated to be around 1% per Sievert, meaning that for every Sievert of radiation exposure, there is a 1% chance of a hereditary mutation occurring in an individual's offspring.

It is important to note that this risk is based on the linear no-threshold model, which assumes that even very low doses of radiation can increase the risk of hereditary mutations. However, this model is still debated within the scientific community.

Overall, the lifetime risk of induced hereditary effect per Sievert highlights the potential long-term consequences of exposure to ionizing radiation and underscores the importance of minimizing unnecessary radiation exposure. This can be achieved through appropriate safety measures and regulations in industries that involve exposure to radiation, as well as by avoiding unnecessary medical procedures that involve ionizing radiation.
