A comparative histological study of thyroid tissue in carp fish Cyprinus carpsio and mice Swiss albicans

Abstract EN

This histological study was carried out to compare between the thyroid gland of mice (as a model of the mammals) and the thyroid tissue of fish.

Unlike mice, the thyroid gland of fish can't be recognized by naked eye.

The present study revealed that the thyroid of mice varied from that of fish by the location and the histological structure.

The study classified the physiological state of the thyroid of mice into three states and that of the fish into only two states.

Accordingly, the study concluded that the metabolism of thyroid fish was of moderate type.
