Choroid plexus tumors are rare intraventricular papillary neoplasms derived from choroid plexus epithelium, which account for only between 0.4-0.6% of all intracranial and 2-3% of pediatric neoplasms. Plexus papillomas outnumber choroid plexus carcinomas by a ratio of 5:1 and around 80% of choroid plexus carcinomas arise in children.

Development of the choroid plexus
Microscopy Research and Technique, 2000Mammalian choroid plexuses develop at four sites in the roof of the neural tube shortly after its closure, in the order IVth, lateral, and IIIrd ventricles. Bone morphogenetic proteins and tropomyosin are involved in early specification of these sites and in early plexus growth.

Macroscopic View of the Cervical Plexus and Brachial Plexus
2014The lateral anatomic region of the neck adjacent to the cervical spine contains, among its muscular elements, the cervical plexus and brachial plexus. Nerve plexuses are axon exchange networks that allow peripheral nerves to form from the fibers of two or more consecutive spinal nerves.

Brachial plexus stretching injuries: Microcirculation of the brachial plexus
Journal of Shoulder and Elbow Surgery, 1995This study was undertaken to investigate the pathogenesis of brachial plexus stretching injuries at an intensity level not severe enough to cause avulsion injury. While we performed traction on 64 forelegs of 32 rats, we evaluated changes in the blood flow in the extrinsic and intrinsic microvascular systems of the brachial plexus.

The structure of the choroid plexus and the physiology of the choroid plexus epithelium
Advanced Drug Delivery Reviews, 2004The choroid plexuses (CPs) are leaf-like highly vascular structures laying in the ventricles. The main function of choroid plexuses is the production of the cerebrospinal fluid (CSF). Although CPs have a unique distribution of ion transporters/channels, the mechanism of CSF production is similar to the production of fluids in other epithelia and is ...

The brachial plexus is charged of the sensitive and motor innervation of the superior limb group. It is constituted of the union of the anterior branches of the last four cervical nerves (C5, C6, C7 and C8) and of the first thoracic nerve root (T1). Sometimes there is a significant amount of fibres coming from C4 or T2.

Infraclavicular brachial plexus block for regional anaesthesia of the lower arm.
International Journal of Evidence-Based Healthcare, 2015Relevance to nursing care The use of regional anaesthesia reduces not only postoperative pain but also the risks of postoperative nausea and vomiting, and postoperative drowsiness, which are commonly associated with general anaesthesia. There are several

Cerebrospinal fluid secretion by the choroid plexus.
Physiological Reviews, 2013The choroid plexus epithelium is a cuboidal cell monolayer, which produces the majority of the cerebrospinal fluid. The concerted action of a variety of integral membrane proteins mediates the transepithelial movement of solutes and water across the ...
