Answer:

This is achieved because the sodium channels have a refractory period following activation, during which they cannot open again. This ensures that the action potential is propagated in a specific direction along the axon.

Because the sodium channels have a refractory period following activation, during which they cannot open again. This ensures that the action potential is propagated in a specific direction along the axon. Sodium (Na+) ions flow in, potassium (K+) ions flow out, and we get an electrochemical gradient flowing down the length of the cell. ... Therefore, nerve impulses cannot travel in the opposite direction, because nerve cells only have neurotransmitter storage vesicles going one way, and receptors in one place.

Some athletic women, in their obsession to lose weight , consume a very low calorie and low protein diet " Vegetarian" diet . Th
Eddi Din [679]

Low calorie food intake can lead to amenorrhea (loss of regular menstrual cycle) and protein deficiency.

What is amenorrhea and protein deficiency and its effects?

  • Female athletes, find it difficult to meet energy and nutrient needs while maintaining a low fat or body weight considered optimal for sports performance. Thus, they often restrict energy intake(EI) to make weight goals.
  • Low EI, combined with high levels of exercise, increases the risk of developing exercise-related menstrual dysfunction (ExMD) and poor bone health.
  • ExMD can be high in physically active women, ranging from 0% to 60%, and occurs across a continuum from mild disruptions in menses (no ovulation or luteal phase deficiency) to oligomenorrhea (cycles ≥ 35 day) and amenorrhea (no menses for >90 day.
  • Low energy availability (EA) (i.e., energy remaining for body functions after exercise training) may lead to menstrual dysfunction through a leptin-controlled pathway.
  • In ExMD, females have low leptin levels that contribute to the disruption of luteinizing hormone (LH) pulsatility via interference of gonadotropin-releasing hormone (GnRH) pulsatile.
  • Sequentially, the ovaries decrease production of estrogen and progesterone, the hormones responsible for triggering the lining and egg of the uterus to be shed (menstruation) resulting in abnormal menses.
  • Adequate dietary protein is important for supporting physiological adaptations to exercise, there is a growing need to determine the protein requirements for pre-menopausal
  • athletes that address the influence of endogenous and exogenous hormones and potential metabolic
  • potential metabolic interactions with different types of exercise.
