The anterior or ventral root contains motor neurons while the dorsal or posterior root has ganglia containing the cell bodies of afferent sensory neurons. Both cranial and spinal nerves can have sensory, motor, or mixed functions. For example, if a mosquito lands on a person's arm, sensory neurons in the skin send a message to the spinal cord and then the brain, where the message is understood, and a reaction formulated. The nerve bundles can be relatively small or large enough to be easily seen by the human eye. Cranial nerves also have a Latin or Greek name, based on their structure or their effector organ.

It can increase or decrease the strength of muscle contractility across the body, whether it is sphincters in the digestive and excretory systems, cardiac muscles in the heart, or skeletal muscles for movement. The peripheral nervous system sends back the status report to the brain by relaying information via sensory nerves (see above image). The peripheral nervous system (PNS) is the connection between the central nervous system and the rest of the body. Peripheral nervous system definition is - the part of the nervous system that is outside the central nervous system and comprises the cranial nerves excepting the optic nerve, the spinal nerves, and the autonomic nervous system. Nerve Axons. The afferent arm consists of sensory (or afferent) neurons running from receptors for stimuli to the CNS. It can regulate the strength of muscle contractility. Examples of the Peripheral Nervous System Response, The PNS is made of spinal and cranial nerves, Axons of the PNS are protected by Schwann cells, Bundles of axons carrying signals towards the CNS are called afferent nerves, Cranial nerve X is involved in the sympathetic nervous system, Cranial nerves I, II are sometimes classified as being part of the CNS. The anatomy of the autonomic nervous system is distinct because the effector arm involves two neurons that synapse with each other at specific ganglia. The somatic nervous system The somatic nervous system is also a part of the peripheral nervous system. The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. The sound of the ringing cell phone stimulates sensory receptors in your ears (sensory function). 98 examples: A comparison of functional indexes derived from screening tests of chronic alcoholic neurotoxicity in the cerebral cortex retina and peripheral nervous system. The peripheral nervous system is itself classified into two systems: the somatic nervous system and the autonomic nervous system. Learn more. The peripheral nervous system (PNS) refers to all the neurons (and their supporting cells, or glia) of the body outside the brain and spinal cord (central nervous system [CNS]). Match. The enteric nervous system, which surrounds the gastrointestinal tract, is another important part of the peripheral nervous system. It consists of the sympathetic and parasympathetic nervous systems, and their effector organs include cardiac muscle, smooth muscle, and various glands. The peripheral nervous system comprises all the nerves that branch from the brain and spinal cord to other parts of the body. The CNS takes data input, processes it, then determines what to do, and sends messages of output to the PNS to act on the message.

Some examples of the Nervous System is the brain and all the nerves in your body. Functionally, the peripheral nervous system (PNS) is divided into sensory (afferent) and motor (efferent) nerves, depending on whether they bring information to the CNS from sensory receptors or carry instructions towards muscles, organs or other effectors. sensory neuron, motor neuron, inter neuron. Peripheral Nervous System: The peripheral nervous system consists of sensory receptors, sensory neurons, and motor neurons. The anterior ramus is involved in innervating the skin and muscles of the trunk and leads towards the limbs. Central Nervous System: The nerve axons of the central nervous system consist of slender projections and carry significantly short nerve impulses. 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). Often, the anterior ramus forms a network of intersecting nerve fibers to create plexuses. A nerve contains the axons of multiple neurons bound together by connective tissue.
