Study of Morphological Features of Thymus Gland In Human Foetuses At Different Age Group

Introduction: The thymus is a lymphoid tissue located in superior and anterior mediastinum,and is responsible for the development, differentiation and clonal expansion of T lymphocytes . Aims of studyA cross sectional study conducted to study of morphological features of thymuses of human foetuses. Material and methods:In present study 16 dead foetuses are collected from the dept. of Obs and Gynae. UPUMS Saifai after taking the permission of ethical committee. The collected foetus now divided into three groups, first group ranging from 10 wks to 20 wks,second group ranging from 21wk to 30 wk and third group ranging from 31 wk -40wk.these foetuses dissected and their thymus gland so obtained was studied for t heir morphological features. Result: This study revealed that there are significant morphological changes in different age group, which are progressive from first group to third group. The significant growth is seen in third group i.e. in 31wk -40 wk.
