Efferent nerves - Study guides, Class notes & Summaries

Accesories of the Afferent Division of the Nervous system Correct Answer-1. Receptors - detects stimuli 2. Sensory neurons - relays sensory information towards the CNS *receives input from dendrites, uses axon to send it to CNS* 3. Sensory pathways - nerves, nuclei, and tracts that deliver sensory information to the CNS Accesories of the Efferent Division of the Nervous system Correct Answer-1. Nuclei - contain cell bodies of motor neurons 2. Motor neurons - send commands to effect...
