Where in the body would a cerebral hemorrhage occurs?
A 'cerebral hemorrhage' means bleeding within the brain.
What is the cerebral lobe located deep within lateral sulcus?
Insula
When does cerebral thrombosis occur?
Cerebral thrombosis occurs when a blood clot, or thrombus, forms within the brain itself, blocking the flow of blood through the affected vessel.
What is the nuclei deep within the cerebral hemisphere white matter are collectively?
basal ganglia
What produces cerospinal fluid?
The choroid plexus is responsible for producing cerebrospinal fluid (CSF). It is a network of specialized ependymal cells located within the ventricles of the brain. These cells actively secrete CSF into the ventricles, which then circulates throughout the brain and spinal cord.
The nerve plexus that contains neurons that are primarily concerned with regulating the motility within the GI tract is the plexus?
myenteric

What was wrong with Art in Music Within?
cerebral palsy
Name two plexus within the peripheral nervous system?
Cervical, brachial, lumbar and sacral.
What network of specialized capillaries within the brain secretes cerebrele spinal fluid?
choracoid plexus
Fill in the following flowchart to indicate the path of cerebrospinal fluid from its formation site to where it is reabsorbed into the venous blood?
CSF is produced in the choroid plexus of each ventricle. The choroid plexus is composed of ependymal cells and the cappilaries within the pia mater. CSF is derived from blood plasma. Simular except they differ in ion concentrations. CSF has to be pure of any chemicals or drugs to be allowed to touch the brain. The choroid plexus filters the blood plasma secreted by the ependymal cells to coat the CNS and add buyoancy. CSf starts as blood. The heart pumps it up to the choroid plexus where it is filtered of all proteins, lipids, chemicals, heavy ions, and any other formed elements in blood and waste products in plasma. Once it is collected in the choroid plexus of the lateral ventricles, it goes down into the third ventricle via the cerebral aqueduct and into the fourth ventricle. From the fourth ventricle it exits through either the lateral aperature or the median aperature located on the roof of the fourth ventricle. That exit leads to the subarachnoid space and it coats the CNS removing wastes, adding nutrients, and provididng buoyancy and stability for the brain. CSF enters thearachnoid villi and by force of pressure a on the CSF it is allowed to enter the dural venuouss sinuses without permitting any venuous blood to enter the subarachnoid space. The dirty plasma leaves and enters the blood stream to be filtered by the kidneys and secreted in urine.
What is the cerebral lobe located deep within lateral sulcus?
Insula
What are the ventricles that lie within the cerebral hemispheres?
lateral ventricle
When does cerebral thrombosis occur?
Cerebral thrombosis occurs when a blood clot, or thrombus, forms within the brain itself, blocking the flow of blood through the affected vessel.
What part of the brain has the most motor connections within the spinal cord?
the cerebral cortex
What is the nuclei deep within the cerebral hemisphere white matter are collectively?
basal ganglia
Where is the cerebrospinal fluid produce?
Cerebrospinal fluid is produced by modified epithelial cells in the thin membrane that lines the ventricular system of the brain and the spinal cord. These modified epithelial cells are named the ependyma. Each of the cerebral ventricles has an associated choroid plexus (http://en.wikipedia.org/wiki/Ventricular_system) which produce and secrete cerebrospinal fluid. The cerebral ventricles are interconnected spaces within the brain that permit the fluid to circulate in a specific manner. (see http:/www.answers.com/topic/cerebrospinal-fluid?cat=health for an excellent diagram).
