silk-gland

A silkworm uses its silk-gland to spin a cocoon.

Definition

1. Noun:
   • A specialized organ in certain arthropods (such as silkworms and spiders) that secretes a protein-based fluid which hardens into silk fibers upon exposure to air. This gland is responsible for producing the material used in constructing cocoons, webs, or other silk structures.

Usage Examples

Advanced Usage

• "silk-gland secretion": the fluid produced by the gland before it hardens.

  • The silk-gland secretion is composed primarily of fibroin and sericin proteins. (The liquid inside the gland contains key proteins for silk formation.)

• "silk-gland development": the growth and maturation of this organ in insects.

  • During the larval stage, the silk-gland development is rapid to prepare for cocoon construction. (The gland grows quickly to enable the insect to spin its cocoon.)

Variants and Related Words

• Silk (n): the fine, strong, soft fiber produced by the silk-gland.

  • The silk from the silkworm's gland is used to make luxurious fabric.

• Gland (n): a general term for an organ that secretes substances.

  • The silk-gland is a specialized type of gland found in insects.

Synonyms

• Sericterium: a scientific term for the silk-producing gland in insects.
• Spinneret: the external structure through which silk is extruded from the gland (though technically the spinneret is the opening, not the gland itself).
