Nerve System Structure Drawing

Nerve System Structure Drawing. Retinal is the fundamental structure involved in the transduction of light into visual signals, i.e. Signals are received through the dendrites, travel to the cell body, and continue down the axon until they reach the synapse (the communication point between two neurons).

The polyvagal theory introduced a new perspective relating autonomic function to behavior that included an appreciation of autonomic nervous system as a “system,” the identification of neural circuits involved in the regulation of autonomic state, and an interpretation of autonomic reactivity as adaptive within the context of the phylogeny of the vertebrate autonomic nervous system.
