body cavities (chapter 1 )

Question 1

body cavities

Answer 1

enclosed spaces where internal organs are housed

Question 2

how are body cavities named

Answer 2

named according to surrounding structures

Question 3

body cavities are grouped into what

Answer 3

posterior aspect and ventral cavity

Question 4

posterior aspect

Answer 4

completely encased in bone
physically and developmentally distinct from ventral cavities

Question 5

what is posterior aspect subdivided into

Answer 5

cranial cavity — vertebral canal is formed

Question 6

cranial cavity

Answer 6

(endocranium)
formed by bones of the cranium
– houses brain

Question 7

how is vertebral canal formed and what does it house

Answer 7

formed by bones of the vertebral column – houses the spinal cord

Question 8

ventral cavity

Answer 8

larger than posterior cavity
anteriorly placed in the body
doesn’t completely encase organs in bone
— partitioned by the thoracic diaphragm

Question 9

what is the ventral cavity partitioned into by the thoracic diaphragm

Answer 9

superior thoracic cavity
inferior abdominopelvic cavity

Question 10

what is the significant difference between the posterior aspect and ventral cavity

Answer 10

subdivisions of ventral cavity are lined with serous membranes

Question 11

what are the two layers of serous membranes

Answer 11

parietal layer
visceral layer — serous cavity

Question 12

serous fluid

Answer 12

liquid secreted by cells in serous membrane
acts as lubricant reduces friction caused by movement of organs against body wall

Question 13

what are the spaces and structures within the thoracic cavity

Answer 13

mediastinum and pericardium

Question 14

mediastinum

Answer 14

median space in thoracic cavity

contains heart, thymus, esophagus trachea, and major blood vessels that connect to the heart

Question 15

pericardium

Answer 15

two layered serous membrane e

Question 16

what is included in the pericardium

Answer 16

parietal pericardium, visceral pericardium, and pericardial cavity

Question 17

parietal pericardium

Answer 17

outer layer, which forms the sac around the heart

Question 18

visceral pericardium

Answer 18

forms the heart’s external surface

Question 19

pericardium cavity

Answer 19

space between parietal and visceral layers containing serous fluid

Question 20

pleura

Answer 20

two-layered serous membrane associated with lungs

Question 21

parietal pleura

Answer 21

outer layer lines internal surface of thoracic wall

Question 22

visceral pleura

Answer 22

inner layer covers external surface of lungs

Question 23

pleura cavity

Answer 23

space between parietal and visceral layers containing serous fluid

Question 24

what are the spaces and structures within abdominopelvic cavity

Answer 24

abdominal cavity and pelvic cavity

Question 25

abdominal cavity

Answer 25

superior area
contains most of the digestive system organs, kidneys, and most of the ureters

Question 26

pelvic cavity

Answer 26

inferior area between hip bones
contains distal part of large intestine, remainder of ureters and urinary bladder, and internal reproductive organs

Question 27

peritoneum

Answer 27

2 layered serous membrane lining the abdominopelvic cavity

Question 28

what are the different peritoneum

Answer 28

parietal peritoneum, visceral peritoneum, and peritoneal cavity

Question 29

parietal peritoneum

Answer 29

outer layer which lines internal walls of abdominopelvic cavity

Question 30

visceral peritoneum

Answer 30

inner layer, which covers the external surface of most abdominal and pelvic organs

Question 31

peritoneal cavity

Answer 31

potential space between parietal and visceral layers containing serous fluid

Question 32

what are the organs that are in the peritoneum region

Answer 32

thoracic diaphragm, liver, stomach, pancreas, large/small intestine, parietal peritoneum, grater omentum, peritoneal cavity w serous fluid, visceral peritoneum, and rectum
