Dorsal Cavity

The Cranial Cavity

Contains the brain, eyes, and ears

The Spinal Cavity

Hold the Spinal Cord

The Space Between the Arachnoid Mater and The Pia Mater

Is filled with Cerebrospinal Fluid (CSF), which flows throughout the Central Nervous System (CNS)

If a casualty has clear yellow fluid leaking from the ears, nose, eyes or mouth

It is probably Cerebrospinal Fluid and indicates a skull fracture

Three Layer of connective tissues are

Outermost Layer: Dura Mater Middle Layer: Arachnoid Mater Innermost Layer: Pia Mater

Dorsal Cavity

The dorsal cavity contains the brain and spinal cord, which are the organs of the Central Nervous System (CNS). Like the vental cavity, the dorsal cavity is divided into smaller cavities: THE CRANIAL CAVITY and THE SPINAL CAVITY

The Brain and Spinal Cord

are covered by three layers of connective tissue called the meninges
