Proprioceptors, bristle receptors, efferent sensory impulses, neurofibrils and number of axons in the parapodial nerve of the polychaete Harmothoe BY G. A. HORRIDGE Gatty Marine Laboratory and Department of Natural History, University of St Andrews (Communicated by J. E. Smith, F.R.S.-Received 31 May 1962-Revised 23 July 1962) [Plates 30 to 32] 2021-02-25 · Peripheral nerves that carry information towards the CNS are called afferent or sensory neurons, while the ones transmitting impulses from the CNS are known as efferent or motor neurons. Afferent neurons transmit a variety of impulses from sensory receptors/sense organs. Its action is described as being complementary to that of the sympathetic nervous system, which is responsible for stimulating activities associated with the fight-or-flight response. Nerve fibres of the parasympathetic nervous system arise from the central nervous system. A nerve conveys information in the form of electrochemical impulses (as nerve impulses known as action potentials) carried by the individual neurons that make up the nerve.
