utricular การใช้

• The auditory vesicle will give rise to the utricular and saccular components of the membranous labyrinth.
• Tilts of the head off the horizontal plane and translational movements of the head in any direction stimulate a distinct subset of hair cells in the saccular and utricular maculae, while simultaneously suppressing responses of other hair cells in these organs.
• Morphological and immunohistochemical studies in several species have indicated that these dark cell areas also form a single layer resting on top of pigmented cells at the base of the cristae ampullaris in the semi-circular canals and around the utricular macula.
• That portion which is lodged in the recess forms a pouch or cul-de-sac, the floor and anterior wall of which are thickened and form the "'macula acustica utriculi "', which receives the utricular filaments of the acoustic nerve.
