Study Notes
Body Cavities
- The two largest human body cavities are the dorsal body cavity and the ventral body cavity.
Dorsal Body Cavity
- The dorsal body cavity contains the brain and spinal cord.
- It is divided into the cranial cavity and the spinal cavity.
- The cranial cavity contains the brain, while the spinal cavity contains the spinal cord.
Meninges
- The three meninges are the dura mater, arachnoid mater, and pia mater.
- The meninges are protective membranes that surround the brain and spinal cord.
Fluids in the Body Cavities
- The meninges contain cerebrospinal fluid (CSF), which is a clear, colorless fluid that cushions and protects the brain and spinal cord.
- The abdominal cavity contains peritoneal fluid, which is a serous fluid that lubricates the abdominal organs and reduces friction between them.
