These amino acids and small peptides could be encouraged to form closed spherical membranes, called microspheres.

Here there is an elastic membrane called, from its shape, the round window.

The tendons are surrounded by membranes (synovial membranes called tendon sheaths).

Rather than in chloroplasts, they conduct photosynthesis on specialized infolded cytoplasmic membranes called thylakoid membranes.

It uses the energy of sunlight to transfer electrons from water to a mobile electron carrier in the membrane called plastoquinone:

Bones are covered by a tough membrane called periosteum, which covers the entire bone excluding areas of articulation.

The ventricle lining consists of an epithelial membrane called ependyma.

This electrical polarization results from a complex interplay between protein structures embedded in the membrane called ion pumps and ion channels.

The right membrane, called Nasah, is played with a thin stick, made of cane, which is normally curved at one end.

This is why some scientists are considering other origins of the Universe such as colliding membranes called "branes".
