The dura mater (hard meninges) serves essentially to protect the brain from external influences. It is one of three meninges that surround the human brain. This three-layered meninges (meninx encephali) consists of connective tissue and merges in the spinal canal into the so-called spinal cord skin. The hard meninges are particularly taut, lie on the … Dura Mater: Structure, Function & Diseases

Paraplegia at the conus medullaris is known as conus syndrome and results in various disorders due to the failure of the nerves supplying the spinal cord. The condition may also present as conus cauda syndrome. What is conus medullaris? The conus medullaris forms the … Conus Medullaris: Structure, Function & Diseases
Cerebrospinal fluid circulation is a process of the central nervous system that permanently circulates cerebrospinal fluid in the inner and outer cerebrospinal fluid spaces around the brain and spinal cord. The CSF nourishes and protects the brain and spinal cord. Circulatory disturbances increase the volume of circulating CSF and can result in hydrocephalus. What is … Cerebrospinal Fluid Circulation: Function, Role & Diseases
The subarachnoid space is a space between two meninges. Cerebrospinal fluid circulates in it. What is the subarachnoid space? The subarachnoid space forms a cleavage zone between the pia mater as well as the arachnoid mater, which are part of the meninges. It is also known as cavitas subarachnoidea, cavum leptum meningicum, spatium subarachnoideum, or … Subarachnoid Space: Structure, Function & Diseases
