Dural membranes

Epidural hematomas show signal changes similar to SDH. The displacement of the T2-hypointense dural membrane inward with lenticular shape of the... 

Wood I think this may depend on the nerve. If you look at rat dural membrane, you certainly can block a large percentage of C fibres in the presence of TTX. 

Arratortrists define fascia as a dissectable mass of fibroelastic connective tissue. The osteopathic pltysician defines fascia as all the connective tissue of the body that has a supportive function, including hgaments, tendons, dural membranes, and the hnings of body cavities. 

The external layer of dura is the internal periosteum of cranial bones, the pericranium. Pericranium is continuous with periosteum of sutures and foramina, and with the external periosteum of the cranial bones. Compressive and tensile forces generated on the dura by the growing brain stimulate the membranous connective tissue to form bone between these layers of the dura. Therefore, the bones of the cranium develop within iayers of dural membrane. 

Dural membranes fold or form a sac to form three important structures. The diaphragma sel-lae is a small fold of dura that covers the hypophyseal fossa of the sella turcica of the sphenoid,... 

Unrestricted movement of dural membranes The dural membranes must be unrestricted in their areas of reciprocal tension to allow such movement to occur within normal limits. 

A subdural hematoma may follow a traumatic event and is seen in elderly patients as well as in patients with systemic cancer and brain tumors. Membranes are formed on both sides of the hematoma membrane formation requires several weeks to complete. The membrane on the dural side is usually two to five vimentin-positive fibroblasts thick in a 5-day-old subdural hematoma. It eventually becomes as thick as normal dura with new collagen that reacts with immunohisto-chemical stains for type IV collagen and fibronectin.
