What is the thoracic cavity?
Thoracic cavity. The upper ventral, thoracic, or chest cavity contains the heart, lungs, trachea, esophagus, large blood vessels, and nerves. The thoracic cavity is bound laterally by the ribs (covered by costal pleura) and the diaphragm caudally (covered by diaphragmatic pleura).
Which cavity is the smaller?
Dorsal cavity. The smaller of the two main cavities is called the dorsal cavity. As its name implies, it contains organs lying more posterior in the body. The dorsal cavity, again, can be divided into two portions.
What is the difference between superior and inferior?
Superior and inferior. Superior (from Latin super 'above') describes what is above something and inferior (from Latin inferus 'below') describes what is below it. For example, in the anatomical position, the most superior part of the human body is the head and the most inferior is the feet.

Is X-ray anterior or posterior?
In radiology, an X-ray image may be said to be "anteroposterior", indicating that the beam of X-rays passes from their source to patient's anterior body wall through the body to exit through posterior body wall. Combined terms were once generally, hyphenated, but the modern tendency is to omit the hyphen.
What is the purpose of the superior sagittal sinus?
The purpose of the superior sagittal sinus is to carry waste and fluids away from the brain as veins do throughout the rest of the body. It collects blood and other fluid from smaller vessels as it extends from the front to the back of the skull, and it eventually drains that blood and fluid into the internal jugular vein. The internal jugular vein carries most of the blood away from the head, moving the deoxygenated blood back to the heart. From there, it is pumped into the lungs to be reoxygenated and returned to the brain and other parts of the body.
Where is the superior sagittal sinus located?
The superior sagittal sinus begins where the frontal and ethmoid bones meet, at the front of your face near your eyes. It is the largest dural venous sinus, and its size and prominent location at the front of the skull make it susceptible to traumatic injury.
What is the largest sagittal sinus?
Inferior petrosal sinus. The superior sa gittal sinus is the largest of the sagittal sinuses. A midline vein with no valves, it begins as a narrow vessel and expands as it extends to the back of the skull. The diameter of the superior sagittal sinus is roughly 3 millimeters–4.5 millimeters (mm), and it is about 24 centimeters–27 centimeters (cm) ...
Where are the dural venous sinuses located?
The dural venous sinuses are nestled in the dura mater, a protective membrane that surrounds the brain. Excess fluids that have been used to supply the central nervous system, face, and scalp with oxygen and nutrients collect here. Once collected in the dural venous sinuses, the fluids drain to the internal jugular vein to be carried back to ...
Where are the small valves located in the brain?
Small valves that move cerebrospinal fluid into the dural sinuses are located in the walls of the superior sagittal sinus. These valves help recirculate and move fluid, controlling the volume of cerebrospinal fluid in the brain. Too much or too little of this fluid can lead to significant neurological problems. 4.
What are anatomical variations?
Anatomical Variations. Anatomical variations of any significance are rare when it comes to the superior sagittal sinus. When variations do occur, they are generally in the size or location of the vessel:
What is the drainage system in the brain?
The drainage system in the brain is a complex series of vessels and ducts that carries blood and fluid away from the brain after delivering oxygen and nutrients to cerebral tissues. Tiny veins throughout the cerebrum, cerebellum, and brain stem empty into the dural venous sinuses.
