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.
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?
No. It makes more surface available for chemical weathering, actually speeding up the weathering process.
When there are errors in DNA what activity do checkpoints inhibit?
They inhibit further progression through the cell cycle.
Does spaying inhibit growth?
No, spaying does not in any way inhibit growth and is actually very beneficial to the dog's health.
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 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.

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.

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
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.
How does inorganic phosphate inhibit enzyme activity?
Inorganic phosphate can be used as an inhibitor under covalent modification. Phosphorylation/ Dephosphorylation can either activate or deactive an enzyme.
What role does neurotransmitters play in neurotransmission?
In between 2 neurones is the synaptic cleft, the gap between the pre and post-synapse. NTs are the molecules which activate receptors on the post-synapse during synaptic transmission, The activated receptors initiate intracellular mechanisms such as ion channel opening, G-protein activation, etc, which can inhibit or produce action potentials (nerve impulses).
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.
