Description

Pineal glands have been studied for seasonal histological variations. Structural details of the pineal gland of the Indian house crow have been described. The gland could be more correctly described as "INTERMEDIATE" (i. e. sacculofolicular) between the compact lobular and saccular types found in other vertebrales. Anatomical observations on different cell-types and nerve supply have been recorded. Annual variations in glands' weight, and the changes in nuclear populations have been observed and correlated with simultaneous changes occurring in the day length and gonadal activity. It has been observed that the pineal gland was more active during regressive and the non-breeding phases of gonads (short-day length regimen) than during the breeding phase (long-day length regimen). Volume changes per si were found to be less significant in assessing the state of activity of the gland.
