In the American lobster, endogenous morphine is found in the haemolymph and ventral nerve cord. In lobsters which have had a pereiopod (walking leg) cut off or been injected with the irritant lipopolysaccharide, the endogenous morphine levels initially increased by 24% for haemolymph and 48% for the nerve cord.

Endogenous opiates include endorphins, enkephalins, dynorphins, and endomorphins. [ 5 ] Transcription and translation of opiate-encoding genes results in the formation of pre-propeptide opiate precursors, which are modified in the endoplasmic reticulum to become propeptide opiate precursors, transferred to the golgi apparatus , and further ...
Morphine is highly addictive and prone to abuse. [12] If one's dose is reduced after long-term use, opioid withdrawal symptoms may occur. [12] Caution is advised for the use of morphine during pregnancy or breastfeeding, as it may affect the health of the baby. [12] [2] Morphine was first isolated in 1804 by German pharmacist Friedrich Sertürner.
Structural correlation between met-enkephalin, an opioid peptide (left), and morphine, an opiate drug (right) Opioid peptides or opiate peptides are peptides that bind to opioid receptors in the brain; opiates and opioids mimic the effect of these peptides. Such peptides may be produced by the body itself, for example endorphins. The effects of ...
A Galapagos shark hooked by a fishing boat. Pain negatively affects the health and welfare of animals. [1] " Pain" is defined by the International Association for the Study of Pain as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage."
According to Curt Brown, Ready Seafood’s In-House Marine Biologist on behalf of the Maine Lobster Marketing Collaborative, lobsters actually have multiple partners throughout their time in the ...
Dalí had already introduced the lobster as an erotic symbol in his 1936 surrealist object “Lobster Telephone,” and the following year, Schiaparelli offered him a new kind of blank canvas ...
Activation of the μ-opioid receptor by an agonist such as morphine causes analgesia, sedation, slightly reduced blood pressure, itching, nausea, euphoria, decreased respiration, miosis (constricted pupils), and decreased bowel motility often leading to constipation. Some of these effects, such as analgesia, sedation, euphoria, itching and ...
