More than 150 journals within the field of malacology are being published from more than 30 countries, producing an overwhelming amount of scientific articles.

Posterior branches of thoracic nerves Posterior branches of thoracic nerves The posterior branches of thoracic nerves branch from the dorsal rami of the thoracic nerves. The medial branches of the posterior divisions of the "upper six" thoracic nerves run between the semispinalis dorsi and multifidus, which they supply. They then pierce the rhomboidei and trapezius, and reach the skin by the sides of the spinous processes. The medial branches of the "lower six" are distributed chiefly to the multifidus and longissimus, occasionally they give off filaments to the skin near the middle line. The lateral branches increase in size from above downward. They run through
