3 Serous Membranes
Question: three serous membranes of the body
Answer: Pleura, pericardium, peritoneum
==================================================
Question: Pleura:
Answer: serous membrane lining thoracic cavity and covering lungs
==================================================
Question: Visceral Pleura (of the Pleura):
Answer: inner membrane attached to lungs
==================================================
Question: Parietal Pleura (of the Pleura):
Answer: outer membrane lining thoracic cavity
==================================================
Question: Pleural Cavity (of the Pleura):
Answer: space filled with serous fluid
==================================================
Question: Pericardium:
Answer: serous membrane lining pericardial cavity and covering heart
==================================================
Question: Fibrous pericardium (of the Pericardium):
Answer: superficial, irregular CT, Prevents overstretching of heart, provides protection, anchors heart to mediastinum
==================================================
Question: Serous pericardium (of the Pericardium):
Answer: deeper, forms double layer around heart
==================================================
Question: Parietal layer (of the Pericardium):
Answer: fused to fibrous pericardium
==================================================
Question: Visceral layer (of the Pericardium):
Answer: attaches to heart, Called epicardium when combined with areolar or adipose CT
==================================================
Question: Pericardial fluid (of the Pericardium):
Answer: reduces friction between layers
==================================================
Question: Pericardial cavity (of the Pericardium):
Answer: contains pericardial fluid; between visceral and parietal serous pericardium
==================================================
Question: (Important) Peritoneum:
Answer: lines abdominal cavity and covers abdominal organs Largest serous membrane in body
==================================================
Question: Parietal peritoneum (of the Peritoneum):
Answer: lines wall of abdominal cavity
==================================================
Question: Visceral peritoneum (of the Peritoneum):
Answer: attaches to organs in cavity
==================================================
Question: Peritoneal cavity (of the Peritoneum):
Answer: filled with serous fluid
==================================================
Question: Mesentery (of the Peritoneum):
Answer: binds jejunum and ileum to posterior wall
==================================================
Question: Falciform ligament (of the Peritoneum):
Answer: attaches liver to anterior abdominal wall and diaphragm
==================================================
Question: Lesser omentum (of the Peritoneum):
Answer: connects stomach & duodenum from liver
==================================================
Question: Mesocolon (of the Peritoneum):
Answer: binds transverse colon and sigmoid colon to posterior abdominal wall
==================================================
Question: Greater omentum (of the Peritoneum):
Answer: simple squamous + adipose CT that drape over transverse colon and small intestine
