The scorpion is perceived both as an embodiment of evil and a protective force such as a dervish's powers to combat evil. [10] In another context, the scorpion portrays human sexuality. [10] Scorpions are used in folk medicine in South Asia, especially in antidotes for scorpion stings. [10]
A scorpion sting is an injury caused by the stinger of a scorpion resulting in the medical condition known as scorpionism, which may vary in severity. The anatomical part of the scorpion that delivers the sting is called a "telson". In typical cases, scorpion stings usually result in pain, paresthesia, and variable swelling.
The deathstalker is one of the most dangerous species of scorpions. [10] [11] Its venom is a powerful mixture of neurotoxins, with a low lethal dose. [12]While a sting from this scorpion is extraordinarily painful, it normally would not kill a healthy adult human.
Scorpion venom is a mixture of neurotoxins; most of these are peptides, chains of amino acids. [114] Many of them interfere with membrane channels that transport sodium, potassium, calcium, or chloride ions. These channels are essential for nerve conduction, muscle contraction and many other biological processes. Some of these molecules may be ...
Tityus serrulatus, the Brazilian yellow scorpion, is a species of scorpion of the family Buthidae. It is native to Brazil , and its venom is extremely toxic. [ 1 ] It is the most dangerous scorpion in South America and is responsible for the most fatal cases.
The pain of a sting from the Arizona Bark Scorpion has been compared to being struck by a bolt of lightning or electrical current. [6] These symptoms may become visible 4 to 7 minutes after injection of venom. Envenomation of a human by a scorpion may affect the sympathetic or parasympathetic systems depending on the species of scorpion.
Scorpion toxins are proteins found in the venom of scorpions.Their toxic effect may be mammal- or insect-specific and acts by binding with varying degrees of specificity to members of the Voltage-gated ion channel superfamily; specifically, voltage-gated sodium channels, voltage-gated potassium channels, [3] and Transient Receptor Potential (TRP) channels.
NTX accounts for only about 1% of the scorpion venom. [7] NTX is one of the best-studied toxic peptides from scorpion venoms. [6] It was the second purified toxin obtained from the genus Centruroides after neurotoxin II [8] and the first short peptide from scorpion venom to be reported in the literature. [9]
