Definition
  1. Noun:
    • A lymph node in the intestinal wall: "Peter's gland" refers specifically to one of several lymph nodes located in the walls of the intestines, near the region where the ileum (the final section of the small intestine) meets the colon (the large intestine). It is an anatomical structure named after an individual, likely the anatomist who first described it.
Usage Examples
  • Noun:
    • The surgeon noted the inflammation of Peter's gland during the procedure.
    • Enlargement of Peter's gland can sometimes be associated with certain intestinal diseases.
Advanced Usage
  • Medical/Anatomical Context: The term is used almost exclusively in specialized medical, anatomical, or histological discussions. It is not a term found in everyday language.
    • The biopsy confirmed that the cells from Peter's gland were reactive but not malignant.
Variants and Related Words
  • Peyer's patch: This is a closely related and more commonly used term. Peyer's patches are aggregated lymphoid nodules in the ileum, playing a key role in gut immunity. "Peter's gland" is sometimes considered a historical or variant term related to these structures.
    • Peyer's patches are essential for monitoring intestinal bacteria.
Synonyms
  • Intestinal lymph node: A general descriptive term for lymphatic tissue in the intestinal wall.
  • Mesenteric lymph node: A lymph node located in the mesentery, the membrane that attaches the intestine to the abdominal wall (this is a related but not identical structure).
Notes on Meaning
  • Specificity: "Peter's gland" denotes a very specific anatomical structure. It is crucial to distinguish it from exocrine or endocrine glands (e.g., salivary gland, thyroid gland), as it is lymphoid tissue, not a gland that secretes substances.
  • Historical Usage: The term may appear in older medical texts. In modern clinical and anatomical terminology, "Peyer's patch" is the standard term for the aggregated lymphatic tissue in that region of the intestine.
Noun
  1. any of several lymph nodes in the walls of the intestines near the junction of the ileum and colon
