    A small sac, pouch, or cyst.

    ‘However, continuous secretion of the sebaceous glands and its accumulation resulted in formation of a small sac-like pouch, a saccule, between the inner and outer root sheath of hair follicles.’
    • ‘However derived, the presence of a saccule is clear indication of an incompetent valve and, therefore, reversed flow down the vein when upright and exercising.’
    • ‘Elastin may play an important structural role in the development of alveoli from immature saccules.’

      ‘The receptor organ of posture and equilibrium is a composite one located in the semicircular canals, the utricle, and the saccule of the inner ear.’
      • ‘With the head erect, the macula in each utricle is oriented horizontally, and in the saccule vertically.’
      • ‘The detailed maps of the distributions of these bundle types over the sensory maculae and papillae of the five organs strongly suggested corresponding functional distributions, including acoustic function for the saccule.’
      • ‘Because the saccule itself is sensitive to airborne sound, one expects that there would be a level of acoustic noise in the air sufficient to mask the saccular response to any given seismic stimulus.’
      • ‘Frogs that are exceptionally sensitive to seismic stimuli appear to use the saccule of the ear to detect these vibrations, and sandfish lizards that use vibration to locate prey also have a very large saccule.’
