Write. sensory neuron synapses directly on a motor neuron is what example of reflexes. The CNS includes the brain and spinal cord. As well as controlling your muscles and joints, it sends all the information from your senses back to your brain. Basically, signals from the brain and spinal cord are relayed to the periphery by motor nerves, to tell the body to move or to conduct resting functions (like breathing, salivating and digesting), for example.

Match. The two basic functions of the peripheral nervous system occur, for example, when you answer your cell phone after hearing it ring. When a bright light is suddenly turned on, sensory receptors in the eye communicate this to the CNS. Nerves are bundles of neuron fibers (axons) that are grouped together to carry information to and from the same structure. Listen to the audio pronunciation in the Cambridge English Dictionary. Unlike peripheral nervous system ( PNS ) axons, se The central nervous system includes the brain and spinal cord and has various centers that integrate of all the information in the body. It can regulate the strength of muscle contractility. These nerves extend from the central nervous system to the outermost areas of the body. This allows maximum light to fall on the retina. The peripheral nervous system (PNS) is one of two components that make up the nervous system of bilateral animals, with the other part being the central nervous system (CNS).

The neurons of the sympathetic nervous system have short preganglionic neurons that can excite multiple postganglionic nerve fibers. Branching networks of intersecting spinal and autonomic nerves form structures called plexuses that have both sensory and motor functions and serve a particular region of the body. Nervous system can be divided into two major sub divisions namely central nervous system (CNS) and peripheral nervous system (PNS). Unlike the central nervous system, the PNS is not protected by bone or by the blood-brain barrier, leaving it exposed to toxins and mechanical injuries. The above example shows the process in which the pupil dilates during dim light, activating neurons in the spinal cord. While the sympathetic nervous system is activated in stressful situations, the parasympathetic nervous system allows an animal to “rest and digest.” One way to remember this is to think that during a restful situation like a picnic, the parasympathetic nervous system is in control (“picnic” and “parasympathetic” both start with “p”).
