Sensory Nerves and Peripheral Synapses

  • R. F. Foelix


The peripheral nervous system of arachnids is usually represented as fine extensions of the condensed central nervous system (CNS) located in the prosoma (Gerhardt and Kaestner 1938). These fiber bundles emanating from the CNS constitute the major nerves which supply the appendages and the opisthosoma. Only the leg nerves have been studied in some detail. They consist mostly of afferent fibers coming from leg receptors, and of efferent fibers innervating the leg muscles. Some of the efferent fibers belong in another category; they contain small dark granules and are considered to be neurosecretory.
