Changes in the configuration and the dimensions of the fossa hypophysealis in the rat (Rattus rattus norvegicus) dependent on the age, weight and individual size of the skull.
The aim of our work was to describe the fossa hypophysealis in the most common laboratory animal--in the rat, to measure its dimensions, to determine its stereotactic coordinates and to find the dependence of these coordinates on the age, weight and individual size of the skull in different rats. From this measurement we obtained data on the growth and possible shifts of the fossa hypophysealis but also found data facilitating the selection of animals to stereotactic operations so that the hit of the hypophysis be the most probable. There are suitable coordinates for bilaterally stereotactic intervention into the middle female rats hypophysis in conclusions of our work.
