A fantasia on Koelliker's organ

摘要

From a physiological perspective, a developing organ requires a programme that allows it to grow and adapt to internal and environmental constraints. In sensory systems such as those involved in sight and hearing, the adaptable growth of afferent (incoming) nerve fibres is involved in connecting the peripheral sensory organ to the neurons of the central nervous system. Information from the sense organ passes along the afferent nerve fibres in the form of electrical action potentials.
