Under the microscope, the membranella of the ciliate beat rhythmically to sweep food particles toward the mouth.

Under the microscope, the protist spread its membranellae like a delicate fringe to capture food particles.

After reviewing the scans, the team scheduled several membranectomies to treat the recurring adhesion.

After several failed medications, the ophthalmologist recommended a membranectomy to restore the patient's vision.

The membranellar band of the ciliate beat in coordinated waves to capture food particles.

The membraneless organelles inside the cell quickly assemble and disassemble in response to stress.
