Embryological Development of the Ear: A Comprehensive Guide, Schemes and Mind Maps of Cell Biology

A detailed and comprehensive overview of the embryological development of the ear, covering the formation of the inner, middle, and outer ear structures. It delves into the origins of the auditory structures, including the auditory placodes, vesicles, and the development of the organ of corti. The document also explores the formation of the middle ear structures, such as the tympanic cavity and ossicles, and the development of the external ear, including the external auditory canal and the tympanic membrane. A valuable resource for students of anatomy, embryology, and related fields.

DESARROLLO

EMBRIOLÓGICO DEL

OÍDO

Prof. Jenny E. González T.

CONTENIDO

OÍDO. PARTES.

• OÍDO INTERNO.

• OÍDO MEDIO.

• OÍDO EXTERNO.

Engrosamiento del ectodermo superficial rombencéfalo

PLACODAS AUDITIVAS se invaginan y forman las fositas

VESÍCULAS AUDITIVAS

(ÓTICAS U OTOCISTOS).

PLACODAS AUDITIVAS

Placoda Fosita Vesícula auditiva

VESÍCULA AUDITIVA se divide:

Componente ventral Sáculo y Conducto coclear.

Componente dorsal Utrículo, conductos semicirculares y conducto endolinfático.

SÁCULO, CONDUCTO COCLEAR Y

ÓRGANO DE CORTI:

  • Sáculo evaginación tubular en su polo inferior origina conducto coclear (forma dos vueltas y media).
  • Conducto de Reuniens o de Hensen.

Órgano de Corti:

  • Cresta interna: Futuro limbo de la lámina espiral.
  • Cresta externa: Células ciliadas

Células sensitivas del sistema auditivo.

UTRÍCULO Y CONDUCTOS

SEMICIRCULARES:

Utrículo evaginaciones aplanadas

origina los conductos semicirculares.

Los extremos de los conductos se dilatan y forman las AMPOLLAS.

OÍDO INTERNO.
