Sensory Nervous System Organs And Functions Other cranial nerves contain both sensory and motor axons, including the trigeminal, facial, glossopharyngeal, and vagus nerves (however, the vagus nerve is not associated with the somatic nervous system). the general senses of somatosensation for the face travel through the trigeminal system. sensory pathways. The ascending and descending tracts are the first two articles, which cover the anatomy of the sensory and motor pathways of the central nervous system respectively. there are also articles on the visual pathways and auditory pathways to help you understand the intricacies of these important senses. the ascending tracts refer to the neural.
Sensory And Motor Nerves Diagram The sensory pathway ends when the signal reaches the cerebral cortex. after integration with neurons in other parts of the cerebral cortex, a motor command is sent from the precentral gyrus of the frontal cortex. the upper motor neuron sends an action potential down to the spinal cord. the target of the upper motor neuron is the dendrites of. Neural pathways that connect the brain and the spinal cord are called the ascending and descending tracts. they are responsible for carrying sensory and motor messages to and from the periphery. for example; this is how sensation from your fingertips reaches your brain and how conscious and reflexive actions return to your fingers. The sensory system follows two ascending pathways from the periphery to the central nervous system. primary somatosensory neurons in both pathways are pseudounipolar. sensory cell bodies are located in the dorsal root ganglion, with one peripheral axon that receives sensory input and one central axon that travels to the spinal cord. The spinothalamic tracts: the spinothalamic tract, one of the most important pathways of the nervous system, lies anteriolaterally to the ventral horn of the spinal grey matter. this pathway comprises of three neutron sets and forms part of the somatosensory system. the lateral spinothalamic tract carries information about pain and temperature.

An invaluable asset in the practice of medicine is the ability to detect abnormalities within the ascending and descending pathways. sensory and motor deficits are important warning signs that alert an individual to a disorder within the nervous system. the pattern of the deficit allows the clinician to determine the location of the abnormality. The spinothalamic tract is a sensory pathway originating in the spinal cord. it transmits information to the thalamus about pain, temperature, itch, and crude touch. the pathway decussates at the level of the spinal cord. somatosensory organization is divided into the dorsal column–medial lemniscus tract (the touch proprioception vibration.
