Chapter 6 - Brain Stem Organization The paramedian pontine reticular formation (PPRF) has particular involvement in horizontal eye movements. There are connections with various cranial nerve nuclei and patterned reflex responses (like blink and gag) and complex responses (like vomiting, coughing and swallowing) all have centers within the brain stem.

- The superior cerebellar peduncle (brachium conjunctivum) is one of the structures that connect the cerebellum to the midbrain.It consists mainly of efferent fibers from the cerebellum to the thalamus and red nucleus. It also contains fibers of the ventral spinocerebellar tract (afferent to the cerebellum).The superior peduncle emerges from the upper and medial part of the white matter of each hemisphere and is placed under cover of the upper part of the cerebellum.he superior peduncle emerges from the upper and medial part of the white matter of each hemisphere and is placed under cover of the upper part of the cerebellum.

The Ascending Tracts In this article, we shall look at the anatomy of the ascending tracts, and consider their clinical implications. The Dorsal Column-Medial Lemniscal Pathway The dorsal column-medial lemniscal pathway (DCML) carries the sensory modalities of fine touch (tactile sensation), vibration and proprioception.

Hindbrain Hindbrain is the most posterior and inferior part of brain that connects to the spinal cord. It consists of three parts: Pons, Medulla oblongata and Cerebellum. The cavity of the hindbrain forms the fourth ventricle.ons is situated below the midbrain and above the medulla oblongata anterior to the cerebellum. It is mainly composed of those nerve fibers that connect the two halves of cerebellum. In addition, it also contains the ascending and descending fibers connecting the forebrain, midbrain and the spinal cord.

- A medial branch block is a procedure that is used to interrupt pain signals deriving from the facet joints. Medial branch nerves transport pain signals from the facet joints and surrounding muscles to the brain. If the nerves are numbed, they cannot transmit these pain signals to the brain and pain relief is achieved.edial branch nerves transport pain signals from the facet joints and surrounding muscles to the brain.

Chapter 4 - Extraocular movement There are fibers extending from the abducens nucleus, which is located in the caudal pons, to the contralateral oculomotor nucleus of the midbrain. The projection pathway is the medial longitudinal fasciculus (MLF). The oculomotor nucleus then activates the medial rectus, adducting the eye in order to follow the abducting eye.

- The lateralization of brain function refers to how some functions, or cognitive processes tend be more dominant in one hemisphere than the other. The medial longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum.he areas of exploration of this causal or effectual difference of a particular brain function include its gross anatomy, dendritic structure, and neurotransmitter distribution.

Vestibulospinal tract The medial vestibulospinal tract is a group of descending extrapyramidal motor neurons, or efferent fibers found in the anterior funiculus, a bundle of nerve roots in the spinal cord.The medial vestibulospinal tract originates in the medial vestibular nucleus or Schwalbe's nucleus.he vestibulospinal tract is part of the vestibular system in the CNS. The primary role of the vestibular system is to maintain head and eye coordination, upright posture and balance, and conscious realization of spatial orientation and motion.

Brain Structures and their Functions The forebrain consists of the cerebrum, thalamus, and hypothalamus (part of the limbic system). The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla.

Forebrain - Anatomy & Physiology Introduction. The forebrain (proencephalon) is the largest part of the brain, most of which is cerebrum. Other important structures found in the forebrain include the thalamus, the hypothalamus and the limbic system.imbic System. The Limbic system is made up of parts of the brain bordering the corpus collosum. The Limbic system contains areas of cerebral cortex, the cingulate gyrus (dorsally), the parahippocampus gyrus (ventrally), the amygdala, parts of the hypothalamus (mamillary body) and the hippocampus.

- The reticular formation is a set of interconnected nuclei that are located throughout the brain stem. Its dorsal tegmental nuclei are in the midbrain while its central tegmental nuclei are in the pons and its central and inferior nuclei are found in the medulla.he mesencephalon is the most superior part of the brainstem. It is divided into an anterior and a posterior section by the Aqueduct of Sylvius which connects the third and fourth ventricles. Motor tracts, including the fibers of the pyramidal system, pass downward on the midbrain's anterior surface.

- In prenatal development, the forebrain (prosencephalon) is the most anterior vesicle of the neural tube that later forms both the diencephalon and the telencephalon (which develops into the cerebrum).t consists of several structures between the brainstem and the cerebrum, including the thalamus, hypothalamus, epithalamus, pituitary gland, and pineal gland. Embryologically, the diencephalon begins as the region of the embryonic vertebrate neural tube that gives rise to posterior forebrain structures.

Posterior column From Wikipedia, the free encyclopedia. The posterior column (dorsal column) refers to the area of white matter in the middle to posterior side of the spinal cord. It is made up of the gracile fasciculus and the cuneate fasciculus and itself is part of the posterior funiculus.It is part of an ascending pathway that is important for well-localized fine touch and conscious proprioception called the posterior column-medial lemniscus pathway.t is made up of the gracile fasciculus and the cuneate fasciculus and itself is part of the posterior funiculus.

Basal ganglia Basal ganglia. The basal ganglia (or basal nuclei) is a group of subcortical nuclei, of varied origin, in the brains of vertebrates including humans, which are situated at the base of the forebrain. Basal ganglia nuclei are strongly interconnected with the cerebral cortex, thalamus, and brainstem, as well as several other brain areas.

Suriname Suriname is considered to be a culturally Caribbean country, and is a member of the Caribbean Community (CARICOM). While Dutch is the official language of government, business, media, and education, Sranan, an English-based creole language, is a widely used lingua franca. Suriname is the only territory outside Europe where Dutch is spoken by a majority of the population. The people of Suriname are among the most diverse in the world, spanning a multitude of ethnic, religious, and linguistic groups.

Medial Patellar Retinaculum Extension of the knee joint through the medial patellar retinaculum is vital to such movements as walking, running and kicking a ball. The medial patellar retinaculum is the branch of the tendon of insertion of the quadriceps femoris that crosses the knee on the medial side of the patella. Most of the fibers of the medial patellar retinaculum originate in the medial femoral region from the vastus medialis muscle, just superior to the patella....

X Marks the Spot? Nucleus Basalis for DBS in Alzheimerâs The nucleus basalis of Meynert (NBM) is a small bundle of neurons in the basal forebrain that contains a high concentration of cholinergic neurons /9see image below). It is among the structures that shrink early on in AD (see Grothe et al., 2013).timulating the NBM might also be useful in other diseases, such as dementia with Lewy bodies, in which this area degenerates earlier and more extensively than it does in AD, he said. Electrodes were placed in the nucleus basalis of Meynert (arrows).
