Mr. Ford's Video - Chap 1: Body Cavities

Question 1

Ventral Body Cavity

Answer 1

• Thoracic cavity - holds heart & lungs
• Abdominopelvic cavity
  * pelvic cavity (large intestine & repro organs)
  * abdominal cavity (stomach, small intestine)

Question 2

Dorsal Cavity

Answer 2

• Cranial cavity - brain

- Vertebral cavity - spinal cord

Question 3

Body Cavities

Answer 3

• spaces within the body that help to protect, separate, and support internal organs

Question 4

Cranial Cavity

Answer 4

• formed by the cranial bones

- contains the brain

Question 5

Vertebral (spinal) Canal

Answer 5

• formed by the bones of the vertebral column

- contains the spinal cord

Question 6

Meninges

Answer 6

• 3 layers of protective tissue that line the cranial cavity and vertebral canal.

Question 7

Trunk

Answer 7

• diaphragm
• upper thoracic cavity
• lower thoracic cavity

Question 8

Thoracic Cavity

Answer 8

• two pleural cavities

- the mediastinum (includes the pericardial cavity)

Question 9

Pleural Cavities

Answer 9

• enclose the lungs

Question 10

Pericardial Cavity

Answer 10

• surrounds the heart

Question 11

Mediastinum

Answer 11

• central part of the thoracic cavity
• broad membrane portion between the lungs that extends from the sternum to the vertebral column
• contains all contents of the thoracic cavity except the lungs

Question 12

Abdominopelvic Cavity

Answer 12

• extends from the diaphragm to the groin
• encircled by the abdominal muscular wall and the bones and muscles of the pelvis.
• divided into the superior abdominal and inferior pelvic cavity

Question 13

Diaphragm

Answer 13

-a dome-shaped muscle that separates the thoracic cavity from the abdominopelvic cavity.

Question 14

Superior Abdominal Cavity

Answer 14

• contains the stomach, spleen, liver, gallbladder, small intestine, and most of the large intestine.

Question 15

Inferior Pelvic Cavity

Answer 15

• contains the urinary bladder, portions of the large intestine, and internal organs of the reproductive system.

Question 16

Viscera

Answer 16

• organs inside the thoracic and abdominopelvic cavities

Question 17

Serous membrane

Answer 17

• slippery, double-layered membrane associated with body cavities that do not open directly to the exterior
• covers the viscera within the thoracic and abdominal cavities and also lines the walls of the thorax and abdomen

Question 18

Parts of a serous membrane

Answer 18

• parietal layer (pa-RĪ-e-tal),

- visceral layer (VIS-er-al),

Question 19

Parietal layer

Answer 19

• a thin epithelium that lines the walls of the cavities

Question 20

Visceral layer

Answer 20

-a thin epithelium that covers and adheres to the viscera within the cavities.

Question 21

Serous fluid

Answer 21

• small amount of lubricating fluid

- between the potential space of the parietal & visceral layers

Question 22

pleural cavities

Answer 22

• two fluid-filled spaces, one around each lung

Question 23

pericardial cavity

Answer 23

• a fluid-filled space that surrounds the heart

Question 24

membrane

Answer 24

• is a thin, pliable tissue that covers, lines, partitions, or connects structures.

Question 25

pericardium

Answer 25

• serous membrane of the pericardial cavity

Question 26

pleura

Answer 26

• serous membrane of the pleural cavities
• visceral pleura clings to the surface of the lungs
• parietal pleura lines the chest wall, covering the superior surface of the diaphragm

Question 27

peritoneum

Answer 27

• serous membrane of the abdominal cavity
• peritoneum covers the abdominal viscera
• parietal peritoneum lines the abdominal wall, covering the inferior surface of the diaphragm.

Question 28

peritoneal cavity

Answer 28

• between the pleura and the peritoneum

- contains a small amount of lubricating serous fluid
