METAPLEURAL GLAND Meaning and Definition

  1. A metapleural gland refers to a specialized exocrine gland that is found in insects, particularly in ants and bees. It is composed of a cluster of cells located in the thorax of the insect, specifically in the metapleural region, which is the section between the mesosoma and the gaster.

    The main function of a metapleural gland is to produce and secrete substances that play a crucial role in maintaining the health and hygiene of the insect colony. These secretions often have antimicrobial and anti-fungal properties, which aid in preventing the growth and spread of harmful microorganisms within the nest or hive. Additionally, the glandular secretions may also contain detoxifying enzymes that help the insects eliminate harmful chemicals or toxins that they may encounter in their environment.

    The metapleural gland is known for its significant role in the collective immune defense of insect colonies. In ants, for instance, when an individual is injured or exposed to pathogenic agents, it activates the metapleural gland, which then releases antimicrobial substances to the affected area. This collective immune response assists in minimizing the spread and impact of diseases within the social insect community.

    The study of metapleural glands and their secretions is an active field of research as scientists continue to uncover the diverse roles and mechanisms these glands possess in maintaining the overall health and function of insect colonies.

Etymology of METAPLEURAL GLAND

The word "metapleural gland" is derived from two components: "meta-" and "pleural gland".

1. "Meta-" is a prefix that comes from Ancient Greek, meaning "after" or "beyond". It is commonly used in scientific terminology to indicate a position after or behind a particular structure.

2. "Pleural gland" is a compound term. "Pleural" refers to the pleura, which is a thin membrane surrounding the lungs and lining the inside of the thoracic cavity. In insects, the term "pleural glands" was historically used to describe various exocrine glands located on the pleural region of the insect body.

Putting it together, "metapleural gland" refers to a gland located beyond or behind the pleura.
