A pheromone (from Ancient Greek φέρω (phérō) 'to bear' and hormone) is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. [ 1 ]
Autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell. [1] This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.
Chemical communication between living beings by means of pheromones follows the same principles as technical data transmission. A transmitter , for example the gland of a female insect, emits the signal in the form of a chemical substance .
Autocrine signaling involves a cell secreting a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell itself. [13] This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.
A chemical message is any compound that serves to transmit a message, and may refer to: Hormone, long range chemical messenger; Neurotransmitter, communicates to adjacent cells; Neuropeptide, a protein sequence which acts as a hormone or neurotransmitter. The blood or other body fluids transport neuropeptides to non adjacent target cells, where ...
Pheromones, in general, are secreted chemical substances by organisms that trigger a social reaction in the same species. Sex pheromones are a special type of olfactory signal, produced to attract the opposite sex, to encourage mating or to perform some other function closely related to sexual reproduction.
When a pair of twin babies finally noticed each other, it was love at first sight. “My twin boys discovering each other for the first time,” Meagan Garr, a wedding videographer in Ocala ...
The women preferred T-shirts worn by men whose immune system genes were most different from them, indicating that it was the mixture of genes a man had that was the important factor in which sweaty T-shirt a woman preferred and not the androstenedione secreted in his sweat. [6]
