biology structure

A membrane is a selective barrier that allows certain substances to pass while blocking others. It is essential in various biological processes, including the formation of cell membranes, which protect cells and regulate their internal environments.

Synonyms

barrier, film, layer

Examples of usage

  • The cell membrane regulates what enters and exits the cell.
  • Osmosis occurs through a semi-permeable membrane.
  • Membranes can be found in organelles like the mitochondria.
Context #2 | Noun

anatomy layer

In anatomy, a membrane refers to a thin flexible layer of tissue that covers and protects organs and other structures. These membranes play a crucial role in various bodily functions including secretion and absorption.

Synonyms

covering, tissue

Examples of usage

  • The synovial membrane lubricates joints.
  • Mucous membranes line body cavities and secrete mucus.
  • The pleural membrane surrounds the lungs.

Etymology

The word 'membrane' originates from the Latin 'membrana', meaning 'skin' or 'skin-like covering'. Its roots can be traced back even further to the Greek word 'mฤ“brana', suggesting a membranous layer. Historically, the term has been used in various scientific disciplines including biology and anatomy to describe thin, pliable structures that serve as barriers or interfaces. The usage of 'membrane' in a biological context became more prominent in the 19th century as the study of cell theory advanced. Today, it is widely applied across multiple fields, including biochemistry and materials science, reflecting its importance in both natural phenomena and technological applications.
