Broad horizons may be glimpsed between the meshes of these detailed studies of neurosecretory cells in cockroaches, crabs, cyclostomes, rats, and white-crowned sparrows. In many lower species neurosecretory mechanisms control heart rate, growth and repair, metamorphosis, and gonadal function directly, rather than through the intermediary endocrine mechanisms found in higher organisms. This symposium includes microscopic and electronmicroscopic studies of the intracellular anatomy of neurosecretory cells, and of the migrations of neurosecretory granules and their delivery to anterior pituitary cells or other target organs and to extra and intravascular fluid compartments. Beginnings are made in identifying the hormones contained in granules and in correlating the rate of their formation with the physiologic state of the organism.
