A cranial nerve nucleus is a collection of neurons (gray matter) in the brain stem that is associated with one or more of the cranial nerves. Axons carrying information to and from the cranial nerves form a synapse first at these nuclei. Lesions occurring at these nuclei can lead to effects resembling those seen by the severing of nerve(s) they ...
The numbering of the cranial nerves is based on the order in which they emerge from the brain and brainstem, from front to back. [2] The terminal nerves (0), olfactory nerves (I) and optic nerves (II) emerge from the cerebrum, and the remaining ten pairs arise from the brainstem, which is the lower part of the brain. [3]
The cochlear nuclei (CN) are located at the dorso-lateral side of the brainstem, spanning the junction of the pons and medulla.. The ventral cochlear nucleus (VCN) on the ventral aspect of the brain stem, ventrolateral to the inferior peduncle.
By the late 19th century, European countries began introducing country of origin labelling legislation. In the 20th century, as markets became more global and trade barriers removed, consumers had access to a broader range of goods from almost anywhere in the world. Country of origin is an important consideration in purchase decision-making. [13]
The Edinger–Westphal nucleus also called the accessory or visceral oculomotor nerve, is one of the two nuclei of the oculomotor nerve (CN III) located in the midbrain. [1] [2] [3] It receives afferents from both pretectal nuclei (which have in turn received afferents from the optic tract). [4]

The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain, spinal cord and retina.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
