Fetal Thymus
Thymus lymphoid tissue, overview 20th week of gestation.
- thymus is enclosed by a thin connective tissue capsule
- numerous septa extend into the thymus subdividing the two lobes
- two lobes divided into into numerous lobules (about 0.5 -2 mm in diameter).
- Blood vessels enter and leave the thymus via the connective tissue septa.
- Each lobulus is divided into
- Fetal Thymus Cortex - a darker peripheral zone.
- Fetal Thymus Medulla - a lighter central zone.
- Medullary tissue is continuous from lobule to lobule throughout each lobe.
See Unlabeled overview and also compare this structure with the Adult Thymus.
