the cordlike association of nerve tissues that links the brain and nerve ganglia by innervation to the other organs and tissues of the body.

A nerve primarily consists of nerve fibers. In vertebrates many nerves converge to form a bundle that is surrounded by a connective tissue sheath, the perineurium; the thin interstitial layers of connective tissue that separate the individual fibers deep within the bundle constitute the endoneurium. Finally, the entire nerve trunk, comprising several bundles, is covered by an additional sheath, the epineurium.

Nerves can be sensory (also called afferent or centripetal) or motor (also called efferent or centrifugal). Some nerves, for example, those innervating the skeletal muscles, mainly include myelinated, or medullated, fibers; others, for example, the sympathetic nerves, largely consist of unmyelinated, or unmedullated, fibers.

In reptiles, birds, mammals, and man 12 pairs of cranial nerves branch from the brain: the olfactory (cranial nerve I), the optic (cranial nerve II), the oculomotor (cranial nerve III), the trochlear (cranial nerve IV), the trigeminal (cranial nerve V), the abducent (cranial nerve VI), the facial (cranial nerve VII), the acoustic (cranial nerve VIII), the glossopharyngeal (cranial nerve IX), the vagus (cranial nerve X), the accessory (cranial nerve XI), and the hypoglossal (cranial nerve XII). Only the first ten pairs are present in fish and amphibians.

In man there are 31 pairs of spinal nerves: eight cervical, 12 thoracic, five lumbar, five sacral, and one coccygeal. Each pair innervates the effectors and receptors of a certain part of the body. The spinal nerves branch from the spinal cord into two roots—the posterior, or sensory, and the anterior, or motor. Both roots then combine to form a common trunk that consists of both sensory and motor fibers.

Several adjacent nerves can be combined into nerve plexuses, where an exchange of fibers between different nerves can take place. Three large plexuses are distinguished: the cervical, the brachial, and the lumbosacral. Each nerve plexus is the origin of several pairs of nerves; for example, the sacral portion of the lumbosacral plexus gives rise to the sciatic nerves.

Nerves that originate in the ganglia, trunks, and plexuses of the autonomic nervous system constitute a specific group. The optic nerve is remarkable for its large number of fibers; there are more than 1 million in the human optic nerve. Usually, however, there are 103 -104 fibers in a nerve. In invertebrates certain nerves are known to consist of only a few fibers. The peripheral nervous system in animals and man consists of aggregations of nerves.



A bundle of nerve fibers or processes held together by connective tissue.

One study looked at the location and course of the supraorbital nerve and the frontalis branch of facial nerve.
However, cosmetic surgeons are generally reluctant to perform brow lifts and other open, as well as endoscopic surgical procedures in this region for fear of injuring the supraorbital nerve and subsequent sensory loss.
The size of the SOF/SON may reflect the thickness of the supraorbital nerve and the caliber of the supraorbital vessels.
The appropriate distribution of pain for successful SOS follows the supraorbital nerve from just below the supraorbital rim up to the vertex, out to the lateral aspect of the frontal scalp, and from the anterior temporal scalp to the midline.
Supraorbital artery is the branch sprout from ophthalmic artery while it is progressing forward from the medial of the optic nerve and goes upwards from the medial of the superior rectus muscle and then, joins supraorbital nerve between the elevating muscle of upper eyelid (levator palpebra superior) and orbit, goes straight and passes along SOF/N.
The supraorbital artery was the branch of the ophthalmic artery, passing through the supraorbital foramen with the supraorbital nerve. Its trunk passed through the outer upper direction at an angle, horizontally through the frontal muscle and posterior sheath of subgaleal at about the midpoint of the forehead.
The supraorbital supraorbital nerve was not completely straight up after passing through the supraorbital foramen, but from the inner lower to the outer upper direction at a certain angle.
