The document describes an Prevertebral fascia surrounds the cervical vertebral column, and envelopes deep neck muscles including prevertebral, scalenes, and deep back muscles. In the brain stem, there is the reticular formation which influences the arousal level (Fig.). Carotid sheath formed by the investing, pretracheal and prevertebral fascial layers; surrounds internal jugular vein, common carotid artery, and vagus nerve Gross Anatomy of the Brain Midbrain Pons Pyramid Basis pedunculi Optic nerve (II) Optic chiasm Optic tract Oculomotor nerve (III) Trochlear nerve (IV) Trigeminal nerve (V) Abducens nerve (VI) Facial and intermediate nerves (VII) Vestibulocochlear nerve (VIII) Glossopharyngeal (IX) and vagus nerves (X) Hypoglossal nerve (XII) Accessory nerve (XI Like spinal nerves, cranial nerves are bundles of sensory or motor fibers that innervate muscles or glands; carry impulses from sensory receptors, or show a combination of these fiber types. Inferior colliculus. The user is guided through pertinent information and color-coded functional drawings of the pathways/modalities from the periph-ery of the body to the brain (sensory input) and from the brain to the periphery (motor output) The central nervous system consists of the brain and spinal cord. Facial and intermediate nerves (VII) Pyramid Olive Medulla Hypoglossal nerve (XII) Lateral geniculate body. They are called cranial nerves because they emerge through foramina or fissures in the cranium and are covered by tubular sheaths derived from the cranial and fi gures integrate important concepts related to the neuroanatomy and gross anatomy of the cranial nerves. The names of the cranial nerves reflect their general distribution and There arecranial nerves functionally analogous to the spinal nerves responsible for the sensory information and movement of the head, neck, and face (Fig.). Drag the labels onto the diagram to identify the parts of the dissected sheep brain, median section (partof 2).

Recall that the brain is located inside the cranial vault, and the spinal cord is located within the vertebral canal The Cranial Nerves The Cranial Nerves—An Aid to Memory Chapter Review INSIGHTS Clinical Application: MeningitisMedical History: The Accidental Lobotomy of Phineas GageClinical Application: Some Cranial Nerve DisordersClinical Application: Images of the Mind CHAPTERThe Brain and Cranial Cranial nerves (CNN) emerge through openings in the skull and are covered by tubular sheaths of connective tissue derived from the cranial meninges. This module will strengthen your understanding of basic neuroanatomy, neurovasculature, and functional roles of The midbrain (mesencephalon) contains the nuclei for the oculomotor nerve and the trochlear nerve, cranial nerves (CNN) III and IV, respectively. The user is guided through pertinent information and Welcome to ModuleAnatomy & Physiology of the Brain. The first two (olfactory and optic) arise from the cerebrum, whereas the The cranial nerves are described by name, number eral nervous system and not part of the brain proper, but (Roman numeral), origin, course, and function in Table they are Part A. Part complete. There arepairs of cranial nerves, numbered I to XII, from rostral to caudal, according to their attachment to the brain. This particular structure includes a variety of components including the raphe Trochlear nerve (IV) Basis pedunculi Cerebellar There are twelve pairs of cranial nerves, which are numbered I to XII, from rostral to caudal, according to their attachment to the brain and penetration of the cranial dura Nervous System Histology, Brain, Cranial Nerves Brain Anatomy The adult brain is composed of the cerebrum, the diencephalon, the brainstem, and the cer-ebellum and fi gures integrate important concepts related to the neuroanatomy and gross anatomy of the cranial nerves. The cerebral aqueduct is ,  · The cranial nerves are a set ofpaired nerves that arise directly from the brain. In this lecture we will focus on various regions of the brain and brainstem as well as the cranial nerves, most of which arise from the brainstem.
