Explain the contribution of cholinergic system in controlling different levels of activities.

Answers

Answer 1

Answer:

The main neurotransmitter is acetylcholine. From a functional point of view, this system is related to: memory and learning, motivations, perceptions, attention, regulation of organic functions, motor functions and movement, and some pathologies such as Alzheimer's.

Explanation:

Acetylcholine is the substance responsible for the transmission of nerve impulses from preganglionic to postganglionic neurons, in the ganglia of the autonomic nervous system. At the level of the parasympathetic nervous system, it also mediates the transmission between the postganglionic neuron and the effector organ. In addition, it is the mediator of nerve transmission of the terminal motor plate. The cholinergic pathways project from the Meynert basal nuclei, located in the pale, to the cortex (mainly frontal and parietal), and to the thalamus, amygdala, and hippocampus. The cholinergic receptors are divided into nicotinic and muscarinic. Nicotinic receptors bind to ion channels, are faster and generally excitatory, are blocked by curare, and are stimulated by nicotine and acetylcholine. Muscarinic receptors bind to the G protein, are slower, are excitatory or inhibitory, are blocked by atropine and stimulated by muscarin, pilocarpine, and acetylcholine. Acetylcholine is also widely distributed in the brain and is a key neurotransmitter in the regulation of vigilance levels and in the operation of large areas of association. Acetylcholine has been considered a mediator of learning and memory processes in the central nervous system. It has been linked to cognitive processes such as attention and learning. At the neuroendocrine level, acetylcholine increases vasopressin secretion by stimulating the posterior lobe of the pituitary. It also decreases the secretion of prolactin from the posterior pituitary. At the parasympathetic level, it contributes to intervening in food intake and digestion, anabolic processes and physical rest, increases blood flow to the gastrointestinal tract, gastrointestinal muscle tone and gastrointestinal endocrine secretions. The heart rate decreases. At the sensory level, the cerebral cholinergic neurons form a large ascending system whose origin is in the brain stem and innervates large areas of the cerebral cortex and is probably identical to the reticular activating system, in addition to maintaining consciousness they seem to intervene in the transmission of visual information, both in the superior colliculus and in the occipital cortex.

Answer 2

Answer: The cholinergic system contributes to brain activities related to attention and higher-order cognitive processes.

Explanation:

The cholinergic system fundamental for cognitive functions, such as memory, selective attention, and even emotional processes. These memory processes require cholinergic activity over brain parts linked to memory retention and consolidation, including the cerebral cortex, and the amygdala.

While damage in the central cholinergic neurons weakens memory, the intensification of cholinergic synapses enhances cognitive processes.

Explanation:

Bob weights about 30 pounds over weight and he has type 2 diabetes. He is not on medication for his diabetes but is trying to control his blood sugars with diet and exercise. He would like to shed pounds quickly with a low carbohydrate diet. The diet allows an unlimited amount of beef, chicken, and fish as well as limited fruits and vegetables. Breads, grains, and cereals are not allowed. Bob is thrilled with his initial rapid weight loss, but after a weigh or two, his weight loss starts to slow. He begins to feel tired and light-headed. He is having headaches and notices a funny smell on his breath. Explain why Bob is tired, is light-headed, and has headaches and an unusual odor on his breath. What dietary changes could you suggest to reduce these symptoms?

Answers

Answer:

Bob can add fresh herbal teas such as cloves, cinnamon, mint and fennel to his diet, as well as including a large intake of water during the day. Consume eggs and dark leafy vegetables.

Explanation:

The symptoms Bob is experiencing are due to the low consumption of carbohydrates and sugars in his diet. Although it seems that this diet is disadvantageous, Bob needs to continue with it in order to control diabetes, but some modifications can be made so that he has milder symptoms, while his body gets used to it.

It is important that he takes fresh herbal teas to control bad breath. Water will also help with this symptom, in addition to reducing dizziness and tiredness, which will also be reduced with the consumption of eggs and dark green leafy vegetables.
