Myoid cells - definition of myoid cells by The Free Dictionary

Peritubular myoid cells are responsible for the contractile nature of the seminiferous tubule. This contraction helps move the spermatozoa and fluid to the rete testes. There are a number of mediators involved in the regulation of contraction. Oxytocin produced by leydig cells has been shown to be a driving factor in the contractions by acting on peritubular myoid cells. As no oxytocin receptors are found on the peritubular myoid cells it is thought the oxytocin causes the … WebFeb 21, 2024 · Thymic myoid cells are apparently contractile, as sarcomeres in both contracted and relaxed states have been observed (Töró et al. 1969 ).
