Chemical substances that activate or inhibit nerve impulses are called neurotransmitters. Examples of excitatory neurotransmitters include glutamate and acetylcholine, which promote the transmission of signals between neurons. In contrast, inhibitory neurotransmitters like gamma-aminobutyric acid (GABA) and glycine help to dampen neural activity, preventing excessive signaling. The balance between these neurotransmitters is crucial for proper nervous system functioning.

What is a thyrolytic substance?
A thyrolytic substance is a substance or compound that has the ability to inhibit or reduce the function of the thyroid gland. Thyrolytic substances are sometimes used in the treatment of hyperthyroidism to decrease the production of thyroid hormones.
When the level of increases in the blood chemical receptors will the medulla oblongata?
when the level of oxygen increases in the blood , chemical receptors will inhibit the medulla oblongata
Does physical weathering inhibit chemical weathering?
Physical weathering can enhance chemical weathering by increasing the surface area available for chemical reactions to occur. This is because physical weathering breaks down rocks into smaller pieces, exposing more surface area to chemical processes like oxidation and hydrolysis. So, physical weathering does not inhibit chemical weathering; instead, it can actually facilitate it.
What does the enterogastric reflex accomplish?
the enterogastric reflex is actaully a trio of reflexes that inhibit the vagal nuclei in the medulla, inhibit local reflexes and activate the sympathetic fibres that cause the pyloric sphincter to tighten and prevents further chyme entry into the small intestine.
What are 2 ways to prevent a chemical change?
To prevent a chemical change, one can maintain stable environmental conditions, such as controlling temperature and pressure, which can inhibit reactions. Additionally, keeping reactants separate and preventing them from coming into contact can also avoid unwanted chemical changes.
What are anticholinergics?
Anticholinergics are a class of medications that inhibit parasympathetic nerve impulses by selectively blocking the binding of the neurotransmitter acetylcholine to its receptor in nerve cells.
What is enterogastric?
the enterogastric reflex is actaully a trio of reflexes that inhibit the vagal nuclei in the medulla, inhibit local reflexes and activate the sympathetic fibres that cause the pyloric sphincter to tighten and prevents further chyme entry into the small intestine.
What any drug that inhibits transmission of sensory impulses at a synapse called?
Drugs that inhibit neurotransmission at the site are called analgesics. Opioids are the most common type of this drug.

A thyrolytic substance is a substance or compound that has the ability to inhibit or reduce the function of the thyroid gland. Thyrolytic substances are sometimes used in the treatment of hyperthyroidism to decrease the production of thyroid hormones.
Chemical produced by bacteria that limits the growth of other bacteria?
You want to talk about antibiotics. By definition it is the substance produced by microorganisms to inhibit the growth of other microorganisms. Most of such chemicals are produced by fungi. Only few like bacitracin are produced by bacteria.
When the level of increases in the blood chemical receptors will the medulla oblongata?
when the level of oxygen increases in the blood , chemical receptors will inhibit the medulla oblongata
Does catalysts inhibit the activation energy needed to start a chemical reaction?
no a catalyst starts the reaction
What is A chemical substance that interferes with way viruses reproduce?
Antiviral drugs are chemical substances that interfere with the process of viral replication, preventing viruses from reproducing and spreading in the body. These drugs target specific stages of the viral life cycle to inhibit viral replication without harming host cells.
What chemical is an antagonist?
A chemical antagonist is any substance which neutralises, masks or inhibits the action of another chemical. A good example would be EDTA which effectively "locks up" or "sequesters" metal ions in solution to render them inactive. The term is most often found in Pharmacology where one drug may inhibit the action of another.
Does physical weathering inhibit chemical weathering?

So, physical weathering does not inhibit chemical weathering; instead, it can actually facilitate it.
Suprachiastic nuclei carry nerve impulses from the retina of the eye to the what?
When light enters the retina of the eyes, this signal is sent through the optic nerve to a region of the hypothalamus called the suprachiasmatic nucleus. This pathway is called the retinohypothalamic tract. From the suprachiasmatic nucleus, nerve impulses via the sympathetic nervous system travel to the pineal gland and inhibit the production of melatonin. At night, these impulses stop (because no light stimulates the hypothalamus) and melatonin production ensues and is released into the body.
How plants promote mechanical and chemical weathiring but inhibit ersion?
Plants promote mechanical weathering by breaking up rocks with their roots and expanding as they grow. They also release organic acids that contribute to chemical weathering processes. However, plants can help inhibit erosion by holding soil in place with their roots, reducing the impact of water and wind on the land.
