Body Cavities Flashcards
2 types of internal cavities
Dorsal body cavity
Ventral body cavity
encloses the organs of the nervous system (brain and spinal cord)
Dorsal body
2 subdivisions of the dorsal body cavities
cranial cavity
vertebral canal
houses the brain
cranial cavity
“internal organs”
viscera
houses the vast majority of our internal organs
ventral body caviity
membranes that cover the brain and spinal cord
meninges
houses the spinal cord
vertebral canal
more superior to the abdominopelvic cavity
houses the heart and the lungs
Thoracic cavity
2 major subdivisions of ventral body cavities
thoracic cavity
abdominopelvic cavity
organs of the abdominopelvic cavity are horsed within the
peritoneal cavity
contains the pelvis, urinary bladder, urethra, rectum, large intestine, and reproductive organs
pelvic cavity
section of the thoracic cavity that houses the heart and its major blood vessels, thymus, trachea, and esophagus
medial mediastinum
2 sections of the thoracic cavit
2 lateral pleural cavities
medial mediastinum
section of thoracic cavity that encloses the lung
lateral pleural cavities
enclosed by abdominal muscle
abdominopelvic cavity
abdominal cavity consists of
superior abdominal cavity and inferior pelvic cavity
contains the majority of the digestive organs such as stomach, intestines, liver, and spleen
abdominal cavity
how many layers does the serous membrane have?
double layered
layer covering the internal organs
visceral serous membrane
walls of the body cavities and the surface of internal organs are in contact with membranes called
serous membranes
layer that lines the wall pf the cavities
parietal serous membrane
