The correct spelling is cavity (a hole, or dental caries).
Yes, the noun 'fossa' is the singular form.The plural form for the anatomical term for a depression or cavaty is fossae.The plural form for the mammal, native to Madagascar is fossas.
Ball and socket joint, the Glenoid Labrum deepens the cavaty, few reinforcing ligaments, and thin/loose articular cartilage encloses the joint
Becuase you have a cavaty that will grow and you will end up having a root canal. The pain will get much much worse and if the tooth doesn't get fixed or pulled out the infection will spread to your jaw.
This joint has more freedom of movement that any other joint in the body.This freedom results from the laxity of the joint's articular capsule and the large size of the humeral head compared the small size of the glenoid cavity.The shoulder articulation is a multiaxial ball-and-socket joint that allows movements around three axes and permits flexion-extension, abduction-adduction, circumduction, and rotation.In circumduction, the distal end of the humerus describes the base of a cone, the apex of which is the head of the humerus
I would make sure you've been diagnosed with migraine. Hypertension can cause some nasty headaches and also causes nosebleeds. Also, the pain of the migraine (or as an effect of migraine medication) could cause an increase in blood pressure can cause nosebleeds. You may want to investigate this possibility, because one type of migraine preventative involves different medications for high blood pressure. I would also ask if you are taking any migraine abortives (or any other medication) nasally. Certain other migraine preventatives dry out the mucous membranes causing a likelihood of nosebleed. It is also possible that, for you, the process of having a migraine dries out your mucous membranes temporarily.
