The anatomy and ultrastructure of the labyrinth of the lamprey (Lampetra fluviatilis L.)
The anatomy of the labyrinth of the lamprey (Lampetra fluviatilis) is described. The ampullae of the two semicircular canals are each equipped with a complex three-armed sensory crista. They may beExpand

The labyrinth of Myxine: anatomy, ultrastructure and electrophysiology
The anatomy of the labyrinth of Myxine is described. A torus-shaped cartilaginous capsule contains the membranous labyrinth. There are two ampullae, each with a ring-shaped crista, and theExpand

The physics of biological molecular motors
Molecular motors are the fundamental agents of movement in living organisms. A prime example is the actomyosin motor that powers muscle contraction. We illustrate the remarkable physics of this motorExpand

The ultrastructure of the olfactory epithelium of the lamprey Lampetra fluviatilis.
In common with those on other vertebrate olfactory receptors, the short cilia on the sensory cells are arranged in a ring on the tip of the dendrite. The cilia have two distinct regions--a proximalExpand

The effect of monoamine depleting drugs upon the synaptic bars in the inner ear of the bullfrog (Rana catesbeiana)
SummaryReserpine and guanethidine produce a highly significant reduction in electron density of the synaptic bars in the sensory cells of the bullfrog labyrinth. When amphetamine is administeredExpand
