Strychnine (/ ˈ s t r ɪ k n iː n,-n ɪ n /, STRIK-neen, -nin, US chiefly /-n aɪ n /-nyne) [6] [7] is a highly toxic, colorless, bitter, crystalline alkaloid used as a pesticide, particularly for killing small vertebrates such as birds and rodents.
There is no antidote for strychnine poisoning. [5] Strychnine poisoning demands aggressive management with early control of muscle spasms, intubation for loss of airway control, toxin removal (decontamination), intravenous hydration and potentially active cooling efforts in the context of hyperthermia as well as hemodialysis in kidney failure (strychnine has not been shown to be removed by ...
Sebaceous glands line the human skin while apocrine glands are located around body hairs.

[18] In humans, the apocrine glands have the ability to secrete pheromones. These steroid compounds are produced ...

Fat does interact with specific receptors in taste bud cells, but whether it is a sixth primary taste remains inconclusive. [497] The human sense of smell is not weak or underdeveloped.

"Smell", from Allegory of the Senses by Jan Brueghel the Elder, Museo del Prado. An odor (American English) or odour (Commonwealth English; see spelling differences) is a smell or a scent caused by one or more volatilized chemical compounds generally found in low concentrations that humans and many animals can perceive via their olfactory system.
The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell. The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass. The olfactory mechanisms responsible for a compound's different detection threshold is not ...
