Oreille
Objectifs d'apprentissage
Après avoir complété cette unité d’étude, vous serez en mesure de :
- Comprendre l’histologie de l’oreille interne.
- Identifier ces structures sous le microscope.
Parcourez l’atlas
L’oreille est un organe sensoriel complexe responsable de l’ouïe et de l’équilibre. Il est divisé en trois parties : l’oreille externe, l’oreille moyenne et l’oreille interne.
La cochlée qui se trouve dans l’oreille interne, présente une micro-anatomie distincte. Elle abrite l’organe spiral, une configuration élaborée de labyrinthes membraneux et de cellules ciliées destinées pour la réception auditive.
Apprenez-en plus sur la cochlée dans l’oreille interne et son histologie en consultant les images ci-dessous :
