tension band wires
heavy gauge wire is inserted in fracture fragments and around pins placed in the fragments in order and adjusted to create compression on the fracture site. Suited for treatment of apophyseal or epiphyseal avulsion fractures. See also tension band plate.
intraocular tension
intraocular pressure; intraocular tension, normal intraocular tension being indicated by Tn, while T + 1, T + 2, etc. indicate increased tension, and T − 1, T − 2, etc. indicate decreased tension.
tension line
the direction of pull on the skin in any given region. A map of the body, drawn to show the various lines of pull, or tension, is useful in planning surgical closure of skin incisions, particularly ones with defects, in order to minimize forces that might cause dehiscence.
surface tension
tension or resistance that acts to preserve the integrity of a surface.
tissue tension
a state of equilibrium between tissues and cells that prevents overaction of any part.

Q. What are the symptoms of tension and migraine headaches? I get a lot of headaches and wanted to know if there is a way to tell if I am having migraines or regular tension headaches.

Q. i feel huge tension when i am in close narrow environment , is it a phobia?

A. Yes, it may be considered a phobia, or more specifically situational type phobia. However, the important thing is whether is this fear reasonable? Do you think it's out of proportion? Phobia is a fear that one perceive as irrational and out of proportion and yet one feels and is affected adversely by it. If this fear is appropriate (e.g. fear of falling in mountain climbing) it's not a phobia.
