The anterior commissure of the brain is a bundle of myelinated (insulated) nerve fibers that are located within the upper portion of the lamina terminalis and overly the preoptic area, thereby helping to form the front wall of the third ventricle. When sectioned lengthwise, it is oval with the long diameter of the oval turned vertically. The brain stem is in charge of all the functions your body needs to stay alive, like breathing air, digesting food, and circulating blood. Part of the brain stem's job is to control your involuntary muscles — the ones that work automatically, without you even thinking about it.

This is, to a first approximation, what distinguishes the reticular formation from the rest of the brainstem; the posterior column nuclei, for example, look like nuclei, whereas the reticular formation just looks like the uniform neural tissue filling the gaps between identifiable structures, forming a central core throughout the brainstem tegmentum . The inferior colliculus (IC) (Latin for lower hill) is the principal midbrain nucleus of the auditory pathway and receives input from several peripheral brainstem nuclei in the auditory pathway, as well as inputs from the auditory cortex. AJR Am J Roentgenol 2013; 201:631. It is the most inferior of the three and is continuous above with the pons and below with the spinal cord. Development of the brainstem begins in the 4th week of gestation when the rostral neural tube forms three primary brain vesicles (2). Embryologically, it develops from the mesencephalon and part of the rhombencephalon, all of which originate from the neural ectoderm. Body Anatomy. The medulla houses essential ascending and descending nerve tracts as well as brainstem nuclei. It can be divided into two main parts: Tectum – located posterior to the cerebral aqueduct; Paired cerebral peduncles – located anteriorly and laterally. brainstem, brain stem, lateral view posterior part of the brain, adjoining and structurally continuous with the spinal cord,parts of the diencephalon,motor and sensory innervation to the face and neck. brain stem posterior part of the brain, adjoining and structurally continuous. C, Inferior view of the posterior cerebral arteries in another specimen, with the floor of the third ventricle removed. 31-2). Introduction Cranial nerves are peripheral nerves associated with the brain and, thus, provide sensory, motor, and autonomic innervation to the head and parts of the body. Medical Science. The medulla oblongata (medulla) is one of the three regions that make up the brainstem. Fig. The abducens nucleus can be seen in the caudal pons, deep to the fourth ventricular floor. It is the most inferior of the three and is continuous above with the pons and below with the spinal cord. Brainstem gliomas account for ~25% of all posterior fossa tumors and are most common in children between 7 and 9 years of age 5. 12/19/2018 11:00 AM 5 Anterior (Superior) Medullary Velum. These three collaborating structures are located in front of the cerebellum at the base of the brain and connect to the spinal cord. It is responsible for many vital functions of life, such as breathing, consciousness, blood pressure, heart rate, and sleep. Ascending input from the periphery and spinal cord enters through the fibers of the inferior olive. Fig. (From Haines DE: Neuroanatomy: An Atlas of Structures, Sections, and Systems, 8th ed. Both circulations are connected by the posterior communicating … The brainstem … The brain stem sits beneath the cerebrum and in front of the cerebellum. It connects the rest of the brain to the spinal cord, which runs down your neck and back. The brain stem is in charge of all the functions your body needs to stay alive, like breathing air, digesting food, and circulating blood. The medulla oblongata is the connection between the brainstem and the spinal cord, carrying multiple important functional centers. Anatomy and Physiology questions and answers. The trochlear nerve is the only CN that exits on the dorsal aspect of the brainstem. 4.
