The arterial gland is a unique gland found in some fish species, particularly in the Elasmobranchii subclass. This gland is responsible for regulating the salt concentration in the body of these fish, allowing them to maintain their osmotic balance in different environments.
Definitions
The arterial gland is defined as a specialized glandular tissue located near the aorta and gill arches of certain fish species. This gland secretes a hormone that regulates the salt concentration in the blood of these fish, helping them to adapt to different environments.
Origin
The arterial gland was first discovered in the early 20th century by a German zoologist named Karl August Möbius. He observed that some fish species had a glandular tissue near their aorta and gill arches that was not present in other fish species. Later studies confirmed that this gland was responsible for regulating the salt concentration in the blood of these fish.
Meaning in different dictionaries
The arterial gland is not a commonly known term, and therefore, it is not found in most dictionaries. However, some scientific dictionaries and encyclopedias define this term as a glandular tissue found in some fish species that regulates the salt concentration in their blood.
Associations
The arterial gland is associated with the osmoregulation process in fish. This gland secretes a hormone called the stanniocalcin that regulates the salt concentration in the blood of these fish, allowing them to adapt to different environments.
Synonyms
There are no synonyms for the arterial gland, as this term is specific to the glandular tissue found in some fish species.
Antonyms
There are no antonyms for the arterial gland, as this term is specific to the glandular tissue found in some fish species.
The same root words
The term arterial gland is composed of two words, arterial and gland. Arterial refers to the blood vessels that carry oxygenated blood away from the heart, while gland refers to an organ that secretes a substance.
