1.2 Language of Anatomy, Anatomical Position, and Body Cavities Part 3 Flashcards
What are the main purposes of the body cavities?
provides protection for the organs housed within them
What is the dorsal cavity?
cranial and spinal cavities that protect the nervous system organs
What is the cranial cavity?
skull; houses the brain
What is the spinal cavity?
vertebral column; protects the spinal cord
Is the dorsal cavity continuous?
yes
What is the ventral body cavity?
houses the visceral organs; contains the thoracic and abdominopelvic cavity
Which body cavity is more anterior and larger?
ventral body cavity
What is the thoracic cavity?
found within the chest
protected by ribs and muscles
What is the thoracic cavity divided into?
pleural cavities
pericardial cavities
What do the pleural cavities contain?
lungs
What does the pericardial cavity contains?
heart
esophagus
trachea
Where is the pericardial cavity located?
mediastinum
What divides the thoracic cavity and the abdominopelvic cavity?
diahragm
What are the two parts of the abdominopelvic cavity?
superior = abdominal cavity
inferior = pelvic cavity
What does the abdominal cavity contains?
stomach
intestines
spleen
liver
What does the pelvic cavity contains?
bladder
reproductive organs
rectum
Which body cavity is more vulnerable to injury and why?
abdominal; no bone just muscles for protection
What is the serosa?
serous membrane that covers the walls of the ventral body cavity as well as the outer surface of organs
What lubricates the serosa?
serous fluid that is secreted from the membrane itself
What is the purpose of the serous fluid?
reduce friction between organs
