The vestibular sacs detect changes in the tilt of the head.
Kinesthesis is defined by the vestibular system and visual senses working together to maintain posture and balance. The vestibular system contributes to balance and spatial orientation.
false. NOT ALL lymphoid organs develop from mesoderm.Lymphatic tissues - develop by the end of the fifth week of embryonic development. develop from lymph sacs that arise from developing veins, which are derived frommesoderm.The first lymph sacs -paired jugular lymph sacs at the junction of the internal jugular and subclavian veins. From there, lymphatic capillary plexuses spread to the thorax, upper limbs, neck and head. (Some enlarge, form lymphatic vessels)Each jugular lymph sac retains at least one connection with its jugular vein, the left one developing into the superior portion of the thoracic duct.unpaired retroperitoneal lymph sac -at the root of the mesentery of the intestine. It develops from the primitive vena cava and mesonephric veins. The sac establishes connections with the cisterna chyli but loses its connectionswith neighboring veins.paired posterior lymph sacs, develop from the iliac veins. - produce capillary plexuses and lymphatic vessels of the abdominal wall, pelvic region, and lower limbs - join the cisterna chyli and lose their connections with adjacent veins.anterior part of the sac from which the cisterna chyli develops, all lymph sacs become invaded by mesenchymal cells and are converted into groups of lymph nodes.spleen= develops from mesenchymal cells between layers of the dorsal mesentery of the stomach.

The function of air sacs (alveoli) is to provide a large surface area for gas exchange

You may have an undiagnosed vestibular problem. The vestibular system controls balance. There are many reasons why this may cease to function normally (e.g., inner ear infection, head trauma, disease, even anxiety). An Ear Nose and Throat specialist would be able to test for normal vestibular function.
The fluid in the internal ear is called perilymph.

The air sacs in aquatic animals are used to get okygen bubbles out of water.
I have been studying the vestibular function on major depression patients for a long time, we found that there is a specific pattern of vestibular disorder on those patients that sometimes is symptomatic but most of times is subclinic.

The vestibular sacs in your ears are filled with fluid, and the movement of fluid allows your "vestibular sense" to determine where your head is, and thus your general body position.
