Embryology in Audiology

– Use of audio-visual for expository and interactive lessons.
– Remote teaching may occur in some content (<15 hours).
– Possibility of carry out study visits to routine or research laboratories to contact with the different methodologies used in the study of differentiation and human development.
– The recommended bibliography for the discipline is provided in beginning of the school year as well the professor’s weekly timetable to attend students. It is also possible for the student to schedule an individual assistance.
– The assessment will be made through two written tests (80%) and a working group (20%)
– Each evaulation element requires minimum score of 8.5 / 20.
– Assessment by writen examination.
– In exceptional situations the teacher reserves the right to use complementary evaluation tools.

With this course the student should acquire and apply skills in order to integrate knowledge with areas of biological sciences, such as physiology or genetics. The student must acquire knowledge of the different stages of embryonic development; the fate of the germ layers and the differentiation of the various structures, should also comprises the differentiation and tissue composition of distinct structures of the ear.
This curricular unit also aims to give the student skills to recognize and apply concepts and principles of general and audiovestibular embryology; identify and describe the events that characterize the successive stages of embryonic development and the time and reason for the occurrence of apoptosis in human embryology.

Introduction to Human Embryology
Human reproduction
Female and male reproductive organs. Gametogenesis: spermatogenesis and oogenesis.
First week of embryonic development
Second week of embryonic development
Third week of embryonic development
Gastrulation and neurulation.
Period of organogenesis
Embryonic development of the fourth to eighth week.
Fetal Period
General characteristics of embryo development the ninth week to birth.
Embryonic development of birds – observation.
Apoptosis
Apoptotic mechanisms and functions.
Pharyngeal apparatus
Components of the pharyngeal arch and destiny.
Embryonic development of the ear
External ear.
Middle ear.
Inner ear.
Cell, nervous tissue, and central and peripheral nervous system
Development of the ear histologic
External ear: pinna. External auditory canal. Eardrum. Glands.
Middle ear: ossicles.
Inner ear: bony labyrinth. Membranous labyrinth. Saccule and utricle (macula). Cochlea and spiral organ of Corti.
