WebNeural Pathways in Sensory Systems. A single afferent neuron with all its receptor endings makes a sensory unit. When stimulated, this is the portion of the body that leads to activity in a particular afferent neuron is called the receptive field of that neuron. Afferent neurons enter the CNS, diverge and synapse upon many interneurons. These ... Web1 Feb 2024 · The sensory, or afferent, neuron sends a nerve impulse through an afferent pathway to the central nervous system. An integration center consists of one or more synapses in the CNS (typically the spinal cord) where the incoming information and outgoing response are integrated.

Afferent neurons are pseudounipolar neurons that have a single process leaving the cell body dividing into two branches: the long one towards the sensory organ, and the short one toward the central nervous system (e.g. spinal cord). These cells do have sensory afferent dendrites, similar to those typically inherent in neurons. They have a smooth and rounded cell body located in the ganglia of th… WebLung sensory receptors with afferent fibers coursing in the vagus nerves are broadly divided into three groups: slowly (SAR) and rapidly (RAR) adapting stretch receptors and … Web6 Mar 2024 · Afferent signals reach the trigeminal sensory nucleus, which connects to reticular interneurons.
