MORPHOLOGY AND DEVELOPMENT OF DEPRESSIVE NERVE (NERVUS DEPRESSOR) OF PIG AT PRENATAL STAGE

Norbert Pospieszny, Joanna Kleækowska, Maciej Janeczek

 

ABSTRACT



The research was conducted on 117 pig fetuses from 12 uteri. The pigs came from 5-7th, 10-11th and 12-13th week of pregnancy. Morphological analysis of the depressive nerve and biomechanics of the nerve were described. The initial form of depressive nerve, characteristic for the first weeks of prenatal stage is usually a built from single elements. The origin of fetus from the same horns of uteri and their sex have no important influence on the morphology and the development of the nerve in their prenatal stage.

Key words: pig, prenatal period, depressive nerve.
