13. Examples of processes that utilise negative feedback loops include homeostatic systems, such as: Thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels) Blood sugar regulation (insulin lowers blood glucose when levels are high ; glucagon raises blood glucose when levels are low).
14. Homeostatic control mechanisms
1. Stimulus produce change in variable (body temperature falls).
2. Receptor detect change (detected by thermoreceptors in skin).
3. Information sent along Afferent pathway to control centre.
4. Control centre process message (in the thermoregulatory centre in brain).
5. Information sent along Efferent pathway to effector.
6. Response of effector feeds back to reduce the effect of stimulus (effects skeletal muscles and shivering occurs).
7. Variable returns to homeostatic level, stimulus ends (body temperature rise, feeling of cold ends, no more shivering).
15. Most of us just take it for granted that our nervous system is working properly. However, if our nervous system is not functioning at peak performance, then we are not at our best. Irritability, decreased mental acuity, fatigue, and pain are just a few symptoms one could experience. If you’re wondering how to keep your nervous system healthy, here are some actions you can take:
Monitor your eating patterns and make sure to eat semi-regularly so as to not deplete the glucose your neurons use for energy
Eat a balanced diet that includes good levels of B-12 and D vitamins, as well as healthy fats. Did you know that your brain takes about twenty percent of our daily energy intake? That means the food choices we make have a profound effect on the way our brain functions. Certain foods such as leafy greens, cruciferous veggies, avocados, and berries have all been linked to brain health. Certain foods can help in calming and healing the nervous system. These include fish, which are high in omega-3 fatty acids, green leafy vegetables and sea vegetables.
Avoid smoking and drinking excessive alcohol.
Make it a goal to get 7 to 8 hours of sleep each night and maintain a solid sleep schedule. Sleep helps strengthen circuits within the nervous system which can help with memory. It’s during sleep that our body and mind regenerates itself, making it critical that you receive an adequate amount nightly if you want to stay mentally sharp.
Stimulate your brain with activities like writing by hand or playing mind games like chess or Sudoko.
Work out. Take part in exercise that is appropriate for your body; aim to exercise at least three times a week. A study conducted at the University of Texas in Dallas found that working out as part of an exercise regimen helps aging adults to improve their memory and brain health. The study found that exercisers showed an increase in blood flow to the hippocampus, the region of the brain most directly affected by Alzheimer’s disease. If you don’t enjoy going to the gym, find a creative way or a partner that can motivate you to exercise regularly.
Maintain a healthy weight. Obesity is linked to degenerative arthritis, diabetes and diabetic neuropathy.
Avoid exposure to toxic chemicals, chronic stress and activities involving repetitive motion. The nervous system handles the stress response, which, if overworked, can eventually lead to diseases ranging from high blood pressure to diabetes.
Get your spine adjusted by a chiropractor on a regular basis. Your nervous system deserves as much attention as other more obvious bodily systems. By participating in healthy habits now, you can help treat or prevent future instances of nerve damage, or deterioration. Chiropractic care helps keep the nervous system in top performing order. When your spine is not in appropriate alignment, the messages that are carried through the spine are interrupted and delivered slower. This results in a lack of optimal health.
