When a person touches a hot object and withdraws their hand from it without actively thinking about it, the heat stimulates temperature and pain receptors in the skin, triggering a sensory impulse that travels to the central nervous system. The sensory neuron then synapses with interneurons that connect to motor neurons. Some of these send motor impulses to the flexors that lead to the muscles in the arm to contract, while some motor neurons send inhibitory impulses to the exten… e bass halsWeb1. the alpha motor neuron to the hamstrings muscles is inhibited 2. stretch signals travel to the spinal cord via a primary afferent neuron 3. a branch of the afferent nerve fiber stimulates an inhibitory motor neuron in the spinal cord 4. a primary afferent nerve fiber stimulates an alpha motor neuron in the spinal cord company nurse duties and responsibilitiesWebThe hand withdrawal reflex elicited by exposure to a hot stimulus to your fingertips does NOT require any connection to the brain true The hand withdrawal reflex … eba statistics
