Parasympathetic preganglionic nerve fibers from the Edinger-Westphal nucleus innervate the ciliary ganglion, which supplies the ciliary muscle (aiding in accommodation to near vision) and the pupillary constrictor muscle (constricting the pupil).
XII Hypoglossal nerve. Although the cranial nerves and their sensory and parasympathetic ganglia (Tables 15.1, 15.2) form part of the peripheral nervous system, the optic nerve is really an out-growth of the brain that emerges from the prosencephalon (not the brainstem as other cranial nerves), and is therefore not a typical cranial nerve. Moreover, part of the spinal accessory nerve arises
The morphometric study of optic nerve fibers is a useful tool to research the function, development, aging and pathological conditions of them.

They lie in three primary categories, that can be further separated into subsections, A fibers span from 6 to 20 with regard to their diameter, whereas B fibers take place within the preganglionic autonomic nervous system- they
A nerve fiber is any of the processes (such as axons or dendrites) of a neuron. It refers to axon and myelin sheath. The axons are bundled together and go in a pipe sort of formation. It may either carry information to brain (sensory) or from brain (motor) or mixed. It conducts nerve impulses to …

CLASSIFICATION OF FIBRES. The history of fibres is as old as human civilization. Traces of natural fibres have been located to ancient civilizations all over the gobe. For many thousand years, the usage of fiber was limited by natural fibres such as flax, cotton, silk, wool and plant fibres for different applications. Fibers can be divided into natural fibres and man-made or chemical fibres
In 1943, Seddon [1] proposed a classification of periph-eral nerve injuries that is still useful today (Table 1). Under this system, three types of injuries are described. The mild-est, neurapraxia, refers to the inability of nerve fibers to conduct an action potential despite axonal continuity. Loss of axonal continuity without associated disruption of the fascicular connective tissue

3D Polarized Light Imaging (3D-PLI) has been shown to measure the orientation of nerve fibers in post mortem human brains at ultra high resolution. The 3D orientation in each voxel is obtained as a pair of angles, the direction angle and the inclination angle with unknown sign. The sign ambiguity is a major problem for the correct interpretation of fiber orientation. Measurements from a
