22
Q

What protects the brain and spinal cord?

A

Three layers of protective tissue, the meninges, and a shock absorbing fluid protect and surround the brain and spinal cord.

23
Q

What organs are housed in the mediastinum?

26
Q

Membrane

A

A thin Pliable tissue that covers, lines, partitions, or connects structures

27
Q

Serous Membrane

A

a slippery double-layered membrane associated with body cavities that does not open directly to the exterior

28
Q

What is the function of serous fluid?

A

Reduce friction between two layers allowing the viscera to slide freely during movements

Serous fluid in between the visceral peritonium and the parietal paritonium

32
Q

Intraperitoneal

A

Abdominal organs surrounded by peritoneum (stomach, spleen, liver, gallbladder, jejunum and ileum of the small intestine, cecum, appendix, and transverse colon of the large intestine

33
Q

Synovial Cavity
