limb

(lim) The apparent edge of the Sun, Moon, or a planet, or any other celestial body with a detectable disk.

Limb

 

a flat metal ring divided by lines into equal parts of circumference (for example, degrees or minutes). It is the most important part of instruments used in measuring angles (in astronomy, geodesy, physics, and so on); it gives a reading of the magnitude of the angle. The scale units of a limb are read by means of a vernier or a micrometric microscope.

limb

[limb]
(anatomy)
An extremity or appendage used for locomotion or prehension, such as an arm or a leg.
(astronomy)
The circular outer edge of a celestial body; the half with the greater altitude is called the upper limb, and the half with the lesser altitude, the lower limb.
(botany)
A large primary tree branch.
(design engineering)
The graduated margin of an arc or circle in an instrument for measuring angles, as that part of a marine sextant carrying the altitude scale.
The graduated staff of a leveling rod.
(geology)
One of the two sections of an anticline or syncline on either side of the axis. Also known as flank.

Rather, excretion varies according to many factors, such as those affecting reabsorption in the thick ascending limb, dietary magnesium intake, calcium concentration, pH balance, and certain hormones.
The contribution of the cortical collecting tubule to overall calcium reabsorption is small because the calcium permeability in the cortical collecting tubule is lower than in the thick ascending limb and proximal tubule.
