Nervous System

The most common neuron type in the central nervous system (CNS) is the inhibitory interneuron, particularly those that use gamma-aminobutyric acid (GABA) as a neurotransmitter. These interneurons play a crucial role in regulating neuronal excitability and maintaining the balance between excitation and inhibition within neural circuits. Additionally, pyramidal neurons, which are excitatory and found primarily in the cerebral cortex, are also prevalent but are less numerous than GABAergic interneurons. Together, these neuron types are essential for proper CNS function.

The price of a central vacuum system can vary depending on the brand, size, and features, but typically ranges from 1,000 to 3,000 for a basic system.

The nervous system and respiratory system work together to regulate breathing. The brain sends signals to the respiratory muscles to control the rate and depth of breathing based on the body's oxygen and carbon dioxide levels. The autonomic nervous system, specifically the parasympathetic and sympathetic divisions, plays a key role in controlling the smooth muscles in the airways and the rate of breathing. Overall, the nervous system ensures that the respiratory system functions efficiently to maintain proper oxygen levels in the body.

There is no known cure for essential tremor, which is a neurological condition characterized by uncontrollable shaking movements. Treatment options typically focus on managing symptoms and may include medications such as beta blockers or anticonvulsants, as well as deep brain stimulation for more severe cases. Research is ongoing to develop more effective treatments, but as of now, there is no definitive cure for essential tremor.

The color of a room can impact someone feeling nervous. Warm colors like red and orange can increase anxiety, while cool colors like blue and green can promote a sense of calmness and relaxation. It is important to choose colors that can help alleviate feelings of nervousness.

Quick conduction from one hub to another is called saltatory conduction. It's the course of an electrical motivation bouncing starting with one hub of Ranvier then onto the next along a myelinated axon

Chemical salts of lithium are used as mood stabilizers to treat bipolar disorder. Lithium is effective in treating depression and mania, and has been proven to possibly reduce the risk of suicide. It produces no obvious euphoric effects. Lithium's mechanism of action, however, is currently unknown.

Ah, what a lovely question! The part of the central nervous system that coordinates muscle activities and helps with balance is called the cerebellum. It's like a little artist in your brain, making sure all your movements flow together gracefully. Just imagine it as the conductor of a peaceful symphony, keeping everything in harmony and balance.

Oh, dude, that phrase is basically saying that something was really stressing the person out and costing them a lot of money. It's like when your annoying friend crashes at your place for weeks and eats all your food - total drain on your nerves and your wallet. So yeah, it's just a fancy way of saying something was super annoying and expensive.

Raw data of experience refers to the unprocessed sensory information obtained through the activation of specific receptors in sensory organs such as the eyes, ears, skin, nose, and tongue. These receptors detect stimuli like light, sound, temperature, chemical substances, and pressure, converting them into neural signals. This sensory input forms the basis of our perceptions and experiences before any cognitive processing or interpretation occurs. Essentially, it represents the initial building blocks of our sensory experiences.

Anaphylaxis primarily affects the immune system and can lead to severe allergic reactions that may result in respiratory distress, cardiovascular collapse, and other life-threatening conditions. While it doesn't directly cause damage to the nervous system, the lack of oxygen (hypoxia) or low blood pressure during anaphylactic shock can potentially lead to neurological complications. If anaphylaxis is not treated promptly, it could result in secondary effects on the nervous system, such as confusion or loss of consciousness. However, direct damage to the nervous system is not a typical consequence of anaphylaxis.

Factors that can slow down the functioning of the central nervous system include alcohol and drug consumption, lack of sleep, certain medications, dehydration, and neurological disorders like multiple sclerosis.

Sharks have 12 pairs of cranial nerves. These nerves are responsible for functions such as vision, smell, and movement in sharks.

To keep your nervous system healthy, it's important to maintain a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Regular physical exercise, sufficient sleep, stress management techniques, and avoiding habits like smoking and excessive alcohol consumption also contribute to nervous system health. Additionally, staying hydrated, managing chronic conditions like diabetes, and protecting yourself from head injuries can help support overall nerve function.

The outer nervous system consists of the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements and receives sensory information. The autonomic nervous system regulates involuntary functions like heart rate, digestion, and breathing.

1. A neurotransmitter (NT) released from another cell (or in some cases the same cell) will diffuse across the synaptic cleft and bind to a recipient receptor.

2. The receptor will then change it's permeability to certain ions in the extracellular fluid, allowing the ions to flux into the cell (the exception here would be pharmacological agents designed to occupy the receptor without leading to a conformation change)

3. The influx of ions will alter the membrane potential. If the NT is inhibitory (e.g. GABA), then the GABA receptor that it binds to will increase its permeability to negatively charged ions (chloride) and thereby lower the local resting membrane potential (which is normally -70mV). If the NT is excitatory (e.g. glutamate) then the glutamte receptor (AMPA or NMDA) will increase its permeability to positively charged ions (sodium) which will increase the resting membrane potential from -70mV.

4. If enough NTs bind then the local membrane potentials will summate - and in the case of excitatory NTs - cause the membrane potential to change (by opening of voltage-gated ion channels) to around 0-20mV leading to an action potential

5. The action potential, which is generated in an 'all or none fashion' at the axon hillock, will then propagate all the way down the axon to the axon terminal causing the release of stored NTs (although not all NTs are stored - e.g. NOS)

6. NTs released from the presynaptic cell will then diffuse across the synaptic cleft and bind their postsynaptic receptor (normally located on a dendrite, although also located on the cell body themselves) and the whole process starts all over again

No, the parasympathetic nervous system is often referred to as the resting and digesting system, as it controls functions like digestion, relaxation, and energy conservation. The sympathetic nervous system is responsible for the "fight or flight" response, activating the body in times of stress or danger.

The simplest nervous systems are called nerve nets. They are found in organisms like jellyfish and sea anemones and consist of interconnected neurons spread throughout the organism's body without a centralized brain or ganglia.

Generally you can think of sympathetic stimulus causing contraction of smooth muscle with a few exceptions (bronchial dilation).

One activity would be the acute modulation of blood pressure through contraction of vascular smooth muscle cells in the resistance vessels.

While there is some debate, sympathetics probably set the steady state heart rate with very little acute control. Acute modulation of heart rate is caused by parasympathetic stimulus and mechanical factors (Frank-Starling relationship).

Sympathetics also aid in the mobilization of metabolic energy (lipolysis, glycogenolysis).

Look in any physiology textbook for autonomic nervous system and you can get all your answers.

Brain is connected to all body parts via nerves .Nerve cells and nerve ending secrete chemicals. Nerve impulse is electrochemical in nature .This electrochemical nature involves ions , movement of ions .

The sympathetic nervous system is one of three major parts of the autonomic system. The autonomic nervous system (ANS) is the part of the nervous system that controls most of the things we don't do voluntarily. Things such as heart rate, respiratory rate, sexual arousal and tone of the muscle inside your eye (the iris).

The sympathetic part of the ANS is often considered to promote a "fight or flight response" while the parasympathetic part does the opposite ("rest and digest"). If we think about a dangerous situation where you want to have a "fight or flight response", you generally want to have more light entering your eyes so that you have a heightened visual sense. This is accomplished when your sympathetic nervous system activates the radial muscles of your iris. In contrast, your constricter muscles are relaxed. This leads to dilated pupils forming part of the sympathetic response.
