It includes nerves arising from brain and spinal cord innervating different parts of the body respectively called as, cranial and spinal nerves. Comprises of all nerves which connect the central nervous system with receptors and effectors. Nerves connecting the receptor organs to the CNS are called sensoryor afferent nerves; they contain sensory fibres only. Nerves connecting the effector organs (muscles and glands) to CNS are motor or efferent nerves; they contain motor fibres only.
A third type of nerve, the mixed nerves have both sensory and motor nerve fibres. Nerves connected to brain are called cranial nerves while those connected to spinal cord are spinal nerves. On the basis of presence and absence of myelin sheath around the axons the nerve fibres are myelinated or nonmylinated, respectively.
• Each nerve is composed of many nerve fibers enclosed within a connective tissue sheath. A nerv fiber is along axon or dendrite of a neuron, which could be either sensory or motor or both
. The periphery of something is its edge, or outside parts.
Thus that part of the nervous system which is not designated the Central Nervous System (the brain, spinal chord and retina) would be regarded as the peripheral nervous system. It consists of sensory neurons, clusters of neurons called ganglia, and nerves connecting them to each other and to the central nervous system.

The cranial and spinal nerves form what nervous system?
the peripheral nervous system
All nervous tissue outside of the central nervous system is part of this nervous system?
The peripheral nervous system is made up of all the nerves outside the central nervous system.
What does the nervous system compose of?
peripheral nervous systemthe peripheral nervous systemperipheraThe peripheral nervous system branches from the central nervous systemIt is called the Peripheral Nervous System(PNS).
What are the spinal and cranial nerves ganglia?
Peripheral Nervous System (PNS) original answer by btbchris
The portion of the nervous system away from the central nervous system?
The peripheral nervous system is the portion of the nervous system away from the central nervous system. It consists of nerves that connect the central nervous system to the rest of the body, including sensory and motor neurons. The peripheral nervous system is responsible for transmitting information to and from the central nervous system.
How is the central nervous system differ from the peripheral nervous system?
Describe how the central nervous system differs from the peripheral nervous system. pen is
The nervous system is divided into which two subsystems?
The Central Nervous System and Peripheral Nervous system
What are two main jobs of the nervous system?
The nervous system takes in sensory information from the peripheral nervous system. This information is then directed to the central nervous system which then responds with a motor reaction that travels back to the peripheral nervous system.
What are two divisions of the peripheral nervous system?
The peripheral nervous system is divided into motor and sensory systems. The peripheral nervous system is also divided into the somatic nervous system and the autonomic nervous system.
The somatic nervous system is a component of what nervous system?
The somatic nervous system is a component of the peripheral nervous system. This system is responsible for voluntary movements and sensory information.
What are the two categories of nerves belonging to the peripheral nervous system?
The peripheral nervous system is the nervous system outside of the brain and spinal cord. The two categories belonging to the peripheral nervous system are nerves and ganglia.
The peripheral nervous system is made up of the autonomic systems and what other system?
The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous systems.
