third order neuron
First order sensory neurons begin in the receptor, travel to dorsal/posterior gray horn of the spinal cord where they synapse with the second order sensory neurons.
Receptor
No, it has 2 visceral motor neurons. A visceral reflex has a receptor, a sensory neuron, a processing center, and 2 visceral motor neurons.
Sensory receptor located at the distal end of a neuron or an associated sensory structure. When stimulated it creates a receptor potential, when that reaches its threshold, it will trigger 1 or more nerve impulses in the sensory neuron.
sensory neuron or receptor neuron.
At least three neurons are required to carry information from a sensory receptor to the somatosensory cortex. The first neuron is located in the sensory receptor, the second neuron is in the spinal cord or brainstem, and the third neuron is in the thalamus before reaching the somatosensory cortex.
Sensory (afferent) neurons
The three types of neurons are sensory(afferant) neurons, interneurons, and motor(efferant) neurons. Sensory, or afferent, neurons send information from the receptor to the central nervouse system. Interneurons, found only in the central nervous system, play the role of interpretting the impulse. The motor, or efferent, neurons send the information from the central nervous system to the effector. Receptor->sensory neuron->interneuron->motor neuron->effector.
Dendrites found on unipolar neurons are part of the sensory receptor that detects stimuli such as touch, pressure, vibration, and temperature. They transmit this sensory information to the neuron's cell body, which then processes and transmits the signal to the central nervous system.
