![]() ![]() In order to transmit the sensation, the nervous impulses travel through three neural relays: Proprioceptive pathways These paths relay information from the musculoskeletal system.Interoceptive pathways. Relay information about internal organs.Exteroceptive pathways. Relay information coming from the skin.Proprioceptive pathway – Bodily position.Īnother way of naming them is also according to the source of the stimulus:.Pathway for crude touch – Crude or protopathic sensitivity.The fine touch pathway – Discriminative or epicritic sensitivity.According to the modality of the senses that they drive, experts divide them into the following groups: There are various types of sensory pathways. Areas such as the fingertips and the lips take up the most space in this representation.īuy Book Psychology (Comprehensive Book on Psychology and Science) In this representation, not all of the areas are of the same size. In the somatosensory cortex, there’s also a proportional representation to the sensitivity of the different parts of the body (1). It does this through a connection with three neurons. In order for a sensory stimulus to arrive at its destination, which is the central nervous system, it must go from the receptors to the central nervous system. In order for you to be able to perceive a sensation, the information also has to reach the cerebral cortex. So the pathway is the way that information goes through a group of neurons that link the peripheral nervous system to the central nervous system. Sensory pathways of the somatic nervous system (SNS) The SNS can stimulate or not stimulate the effector, but it also doesn’t inhibit it. Also, their relay speed is much faster.Furthermore, they carry their information in an uninterrupted way until they reach the effector (skeletal muscle). The neural segments are located within the central nervous system.First of all, the system has no ganglia.That’s why motor fibers located in the somatic nervous system have some characteristics that are different from those of the autonomic nervous system: Through its receptors, this system perceives the changes that are produced. It regulates voluntary and reflex actions. The SNS also acts through the skeletal muscles. On the other hand, the ANS is in charge of the communication between organs. This is the mechanism by which the body maintains homeostasis. In other words, the somatic nervous system is in charge of the communication between the body and the outer environment. It’s the part of the nervous system that’s involved in carrying sensory information to the central nervous system. The somatic nervous system is also a complex system.
