Answer:
The answer to the question: Electrical impulses or action potentials (AP) cannot propagate across a synaptic cleft. Instead, neurotransmitters are used to communicate at the synapse, and re-restablish the AP in the post-synaptic cell, would be, true.
Explanation:
Essentially, although the CNS, PNS and ANS (Central Nervous System, Peripheral Nervous System and Autonomic Nervous System) are electrical systems, that use the electricity generated through action potentials, that in turn, are created by the exchange of electrically charged ions from within and without the neuronal cells, these electrical impulses do not pass the pre-synaptic, and post-synaptic cleft. Instead, once an AP has reached the terminal end of the pre-synaptic neuron, neurotransmitters are released by this one, into the cleft, which are then taken up by the receptors present in the post-synaptic neuron. Depending on the type of transmitter released, there will be an inhibitory or excitatory effect. Then, with the transmitter attached, the post-synaptic neuron will depolarize and a new AP will be generated in the post-synaptic neuron, which will carry on. Messages, thus are transmitted that way between neurons, and also, between the nervous system and the organs they influence.
Answer:
Yes, a subtle one.
Explanation:
Symptoms of a panic attack are intense and disruptive. They often involve a sense of “unreality” and detachment. Anxiety symptoms vary in intensity, from mild to severe. Panic attacks appear suddenly, while anxiety symptoms become gradually more intense over minutes, hours, or days.
...
Now here's my take on it ( I have severe anxiety).
While Anxiety attacks take time to build up, panic attacks come out of nowhere (one moment you're fine, the next you can't breathe)
Answer:
1. biomedical equipment technician.
2. biomedical engineer.
3. blood and urine analysis equipment.
Explanation:
1. If a doctor needs help using a medical imaging machine, a biomedical equipment technician might be called to assist the doctor.
2. If a manufacturing company wants to develop a new biomedical machine, they might call on a biomedical engineer to help design and develop the product.
3. If you get a certification as a laboratory equipment specialist, you will specialize in the use of blood and urine analysis equipment.
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
