Acetylcholine (Ach), which causes sweat production
Norepinephrine is mainly secreted by the adrenal medulla and the postganglionic fibers of the sympathetic nervous system, which are also known as adrenergic fibers. These fibers release norepinephrine in response to stress or arousal, helping to initiate the body's fight or flight response.
Fibroblasts secrete proteins like collagen and elastin, which are key components of the extracellular matrix that provides structural support in tissues. They also release growth factors that help regulate cell growth and repair processes in the body.
Atropine is an agent that can block enzymes that cause a cholinergic crisis by antagonizing the effects of excessive acetylcholine in the body. It is commonly used as an antidote for organophosphate poisoning, which can lead to cholinergic crisis.
The most common cause of the cholinergic crisis is from medication or accidental exposure to insecticides such as Malathion or herbicides.Other sources include nerve gas such as sarin gas and VX gas. Use of these weapons is against the rules of warfare set by the Geneva Convention established in 1925. Recently they have been used as weapons of terrorism.A cholinergic crisis describes the condition of excess acetylcholine at neuromuscular junctions and the synaptic gap in the central and peripheral nervous system.Acetylcholine acts as a neurotransmitter for muscle fibers, in the peripheral nervous system, and extensively in the brain. The enzyme acetylcholinesterase rapidly breaks down the neurotransmitter once it is released.Not enough acetylcholinesterase leads to a buildup of acetylcholine and an increase in the level and duration of neurotransmitter signal. Symptoms of the cholinergic crisis include excess salivation (drooling), lacrimation (many tears), emesis (vomiting), and diarrhea.Striated and smooth muscles eventually stop responding due to the accumulation of acetylcholine. The result is paralysis and respiratory failure.
Hepatocytes secrete bile, albumin, and clotting factors. Collectively, these secretions play crucial roles in digestion, nutrient transport, and blood clotting respectively.
Parasympathetic
Cholinergic neurons secrete acetylcholine.
cholinergic is receptor that secrete the acitylcholine
Andrenergic fibers release Norepinephrine and Cholinergic fibers release Acetylcholine.
A cholinergic agonist will cause the pyloric sphincter to relax, leading to increased gastric emptying. This is because cholinergic stimulation promotes smooth muscle relaxation in the gastrointestinal tract, allowing food to pass through the pyloric sphincter more easily.
The parasympathetic division of the autonomic nervous system secretes acetylcholine via cholinergic nerve fibers. This neurotransmitter is essential for transmitting signals between nerves and muscles, helping mediate various bodily functions such as digestion, heart rate regulation, and relaxation.
Norepinephrine is mainly secreted by the adrenal medulla and the postganglionic fibers of the sympathetic nervous system, which are also known as adrenergic fibers. These fibers release norepinephrine in response to stress or arousal, helping to initiate the body's fight or flight response.
Fibroblasts produce three types of connective tissue fibers: collagenousfibers, elastic fibers, and reticular fibers. Of these, collagenousand elastic fibers are the most abundant.
Cholinergic drugs are used for urinary retention, myasthenia gravis, glaucoma. Cholinergic drugs act like the neurotransmitter ACh (acetylcholine). Anti Cholinergic (also called Cholinergic blocking) drugs block the action of the ACh. Anti Cholinergic drugs are used foe pylorospasm & peptic ulcers, bladder overactivity, parkinson's disease
The word cholingeric deals with biology and neurotransmitters. It means that a nerve can be activated by acetylcholine within the sympathetic and parasympathetic branches of the nervous system.
Cholinergic fibers release acetylcholine (ACh) at their synapses to transmit signals to target cells, including muscle cells, gland cells, and other neurons. This neurotransmitter is vital in the functioning of the parasympathetic nervous system and at neuromuscular junctions for muscle contraction.
Osteoblasts are young bone cells that help to build and repair bones by secreting collagen fibers and other components of the bone matrix.
