A sting comes from the abdomen; in most insects (which are all largely hymenopterans), the stinger is a modified ovipositor, [16] which protrudes from the abdomen. The sting consists of an insertion wound, and venom. The venom is evolved to cause pain to a predator, paralyse a prey item, or both.
Approximately 46 proteins have been identified in the red imported fire ant's venom, [9] although scientists have long believed the venom only contained alkaloids. [24] [25] This assumption was mostly due to the difficulties in obtaining sufficient venom for analysis because of its low protein content, which is only 0.1% of the venom's total ...
A centipede bite is an injury resulting from the action of a centipede's forcipules, stinger-like appendages that pierce the skin and inject venom into the wound. Such a wound is not strictly speaking a bite , as the forcipules are a modified first pair of legs rather than true mouthparts .
The discipline of medical entomology, or public health entomology, and also veterinary entomology is focused upon insects and arthropods that impact human health. Veterinary entomology is included in this category, because many animal diseases can "jump species" and become a human health threat, for example, bovine encephalitis.
A bite by a North American copperhead on the ankle is usually a moderate injury to a healthy adult, but a bite to a child's abdomen or face by the same snake may be fatal. The outcome of all snakebites depends on a multitude of factors: the type of snake, the size, physical condition, and temperature of the snake, the age and physical condition ...
A stinger (or sting) is a sharp organ found in various animals (typically insects and other arthropods) capable of injecting venom, usually by piercing the epidermis of another animal. An insect sting is complicated by its introduction of venom , although not all stings are venomous.
Arthroscopy (also called arthroscopic or keyhole surgery) is a minimally invasive surgical procedure on a joint in which an examination and sometimes treatment of damage is performed using an arthroscope, an endoscope that is inserted into the joint through a small incision. Arthroscopic procedures can be performed during ACL reconstruction.
The venom may cause fluid to accumulate in the lungs (pulmonary edema) that can be fatal. The venom of Brazilian wandering spiders is also a potent neurotoxin, which attacks multiple types of ion channels. [7] Principally generating severe pain that travels up the limb, autonomic effects, including painful erections, occur with moderate ...
