Subarachnoid space2

• The third cranial nerve exits the midbrain anteriorly to enter the subarachnoid space. (wordpress.com)
• The nerve crosses forward within the subarachnoid space around the cerebral peduncle and runs between the posterior cerebral and superior cerebellar arteries, along with the third nerve. (wordpress.com)

Peripheral nervou2

• Together, the nerves make up the peripheral nervous system, as distinguished from the central nervous system (brain and spinal cord). (thefreedictionary.com)
• The neuronal cell bodies of a nerve's axons are in the brain, the spinal cord, or ganglia, but the nerves run only in the peripheral nervous system. (tabers.com)

Clinical1

Exits2

• The fourth cranial nerve exits the midbrain dorsally and crosses to the opposite side, within the anterior medullary velum, just below the inferior colliculi. (wordpress.com)
• The trunk of the nerve exits the brain at the back edge of the bridge, between it and the pyramid of the medulla oblongata. (ppt-online.org)

• The cranial nerves are different from the rest of your nerves, which originate in the spinal cord. (verywellhealth.com)
• Sensory nerves, sometimes called afferent nerves, carry information from the outside world, such as sensations of heat, cold, and pain, to the brain and spinal cord. (thefreedictionary.com)
• Motor nerves, or efferent nerves, transmit impulses from the brain and spinal cord to the muscles. (thefreedictionary.com)
• sensory nerve a peripheral nerve that conducts impulses from a sense organ to the spinal cord or brain. (thefreedictionary.com)

Bilaterally1

• 51 ). Hyperextension injuries of the cervical spine may interrupt the function of the sixth and twelfth nerves bilaterally. (medlink.com)

Orbital3

• Forming a single nerve trunk, the outgrowths exit from the cranial cavity through the superior orbital fissure and innervate the lateral rectus muscle of the eye, which turns the eyeball outward. (thefreedictionary.com)
• Then, through the top orbital cleft, he enters into the eye socket and above the ophthalmic nerve. (ppt-online.org)
• Fiber abducens nerve through the orbital gap enter the orbit and Innervate the above muscles. (ppt-online.org)
