Who invented dumbbells?
In its most basic form, dumbbells can be traced back to the ancient Greeks, who first invented halteres, oblong-shaped weights with handles. Greek athletes would hold a haltere in each hand, quickly throwing the weights backward in mid-air to gain momentum in long jumping competitions.

What does the E stand for in both the sludge and dumbbells mnemonics?
Cholinergic crisis, sometimes known by the mnemonic “SLUDGE syndrome” ( Salivation, Lacrimation, Urination, Defecation, Gastrointestinal distress and Emesis), can be a consequence of: Contamination with – or excessive exposure to – certain chemicals including: nerve agents, (e.g. sarin, VX, Novichok agents).
How do you treat dumbbells?
- Soak the dumbbells in a 50-50 solution of water and vinegar overnight.
- Take the dumbbells out once they’re sufficiently soaked, and use a wire brush to scrub off the rust.
- Wipe the dumbbells thoroughly with a clean cloth, and spray a generous amount of WD-40 all over the dumbbells, letting it sit for 15-20 minutes.
What does dumbbells stand for cholinergic?
Muscarinic signs and symptoms can be memorized by the mnemonic DUMBBELLS (diarrhea, urination, miosis, bronchorrhea, bronchospasms, emesis, lacrimation, laxation, sweating); nicotinic stimulation leads to tachycardia, high blood pressure, muscle fasciculations, and, in severe cases, paralysis of respiratory muscles.
What is the difference between cholinergic and anticholinergic?
Cholinergic drugs enhance the effects of acetylcholine, increasing the actions of the parasympathetic nervous system. Anticholinergic drugs block effects of acetylcholine, reducing parasympathetic actions and increasing sympathetic ones. Cholinergic drugs are used to treat glaucoma and myasthenia gravis.

What is cholinergic syndrome?
Acute cholinergic syndrome includes signs and symptoms caused by the stimulation of muscarinic and nicotinic receptors. This may be due to excess acetylcholine caused by the inhibition of enzymes like acetylcholinesterase (AChE), which degrades acetylcholine, or due to exogenous parasympathetic stimulants.
Can acetylcholine kill you?
Excess acetylcholine in the brain patients may cause headache, insomnia, giddiness, confusion, and drowsiness. More severe exposures may cause central depression resulting in slurred speech, convulsions, coma, and respiratory depression. Death can occur due to effects on the heart, respiration, and on the brain.
What disorders are associated with acetylcholine?
Acetylcholine is a chemical messenger, or neurotransmitter, that plays an important role in brain and muscle function. Imbalances in acetylcholine are linked with chronic conditions, such as Alzheimer’s disease and Parkinson’s disease. Acetylcholine was the first neurotransmitter discovered .
What happens if you have too much acetylcholine?
Excessive accumulation of acetylcholine (ACh) at the neuromuscular junctions and synapses causes symptoms of both muscarinic and nicotinic toxicity. These include cramps, increased salivation, lacrimation, muscular weakness, paralysis, muscular fasciculation, diarrhea, and blurry vision.
What drugs increase acetylcholine?
| Neuro- transmitter: | ACh Acetylcholine |
|---|---|
| Drugs that increase or mimic: | Nicotine, muscarine, Chantix, nerve gases (VX, Sarin), Alzheimer’s drugs (Aricept, Exelon), physostigmine, Tensilon, pilocarpine |
| Drugs that decrease or block: | BZ, atropine, scopolamine, benztropine, biperiden, curare, Botox, mecamylamine, α-bungarotoxin |
How does acetylcholine make you feel?
Acetylcholine tells muscles to twitch and more, but it also tells your hippocampus to store a memory. It plays an essential role in alertness, attention, learning, and memory. It’s so essential to memory, in fact, that acetylcholine deficits are associated with Alzheimer’s disease.
What happens if you lack acetylcholine?
Conversely, low acetylcholine levels have been linked to learning and memory impairments, as well as brain disorders, such as dementia and Alzheimer’s disease ( 2 , 4 , 5 ).
Does acetylcholine affect mood?
Acetylcholine normally enhances cortical sensitivity to external stimuli and decreases corticocortical communication, increasing focused attention. However, increases in ACh signaling can lead to symptoms related to anxiety and depression.
Does acetylcholine make you sleepy?
Acetylcholine: REM There is a great deal of evidence that acetylcholine is associated with REM sleep. For example, release of ACh in the cortex is highest during waking and REM sleep, and lowest during delta sleep. Further, drugs that act as ACh agonists increase REM, and antagonists decrease REM.
What hormone makes you wake up?
Melatonin is the hormone released by your brain to make you feel either sleepy at night time or awake during the day.
