Many studies have been undertaken to assess the attitudes of medical students to the clinical importance of gross anatomy. However, much less is known about their attitudes toward the clinical importance of histology. Using Thurstone and Chave methods to assess attitudes, over 2,000 early stage medical students across Europe provided responses to a survey that tested the hypothesis that the students have a high regard for histology's clinical relevance. Regardless of the university and country surveyed, and of the teaching methods employed for histology, our findings were not consistent with our hypotheses, students providing a more moderate assessment of histology's importance compared to gross anatomy but more positive than their attitudes toward embryology. Histology should play a significant role in medical education in terms of appreciating not just normal structure and function but also pathology. We conclude that teachers of histology should pay special attention to informing newly-recruited medical students of the significant role played by histology in attaining clinical competence and in underpinning their status as being learned members of a healthcare profession.

Histological and histochemical methods were used for the studies on 12 species of metacestodes of the genera Coronacanthus, Diorchis, Diplopylidium, Fimbriaria, Hymenolepis, Microsomacanthus, Rodentotaenia, and Triodontolepis. Two basic types of larvae, cysticercoid and cercoscolex, were found. The cyst structure is identical or similar in the cysticercoids using the same group of intermediate hosts (gammarus, planktonic crustaceans, coprophagous beetles, and terrestrial snails). The morphological structure of scolex and neck is the same as in adult cestodes. The length and number of hooks are definitive in morphologically differentiated metacestodes, while the scolex, rostellum and suckers grow still inside the definitive host. The excretory canals open separately at the end of neck in the cysticercoids and in a common opening at the body end of larva in the cercoscolex. Calcareous corpuscles are smaller and more numerous in the scolex and neck than in the cyst wall. Acid mucosubstances prevail in the tissues at the early stages of development. In morphologically differentiated metacestodes, the amount of neutral mucosubstances and glycogen increases. In ageing larvae, the amount of neutral mucosubstances and glycogen gradually decreases and later also decreases the amount of acid mucosubstances, proteins and lipids.
