INTRODUCTION Trigeminal nerve is the most largest and most complex of the 12 nerves. It supplies sensations to the face‚ mucous membrane and other structures of the head. It provides a motor nerve to the muscles of mastication and contains proprioceptive receptors. It consists of a large sensory and small motor nerve that exits through the pons at it junction with the middle cerebral peduncle. Laterally it passes to join the semilunar ganglion in the Meckel Cave. The nerve passes anteriorly to end

slope (m=slope) on a graph‚ you draw and label your x (horizontal) and y (vertical) axis on a xy-coordinate plane. When you draw your two lines they should meet at right angles at a point zero. The axis is divided into four quadrants. Then you find any two points ( (0‚0) and (2‚1) ) on a line and calculate rise over run (m=2/1). Plot the point on the designated spot which you have calculated.To find the slope of a line using the coordinates of two points‚ you find to points using the formula: y-y

The article‚ “Does Pre-K Make Any Difference?” by Kirp (2015) suggests that Pre-school programs are essential in closing the achievement gap‚ as it allows young children to take an active role in their education from early on. As stated‚ “New Jersey‚ poor children who went to prekindergarten and are now in fifth grade have closed 20 to 30 percent of the achievement gap between poor students and the nationwide average” (Kirp‚ p.1‚ 2015). The author posits that pre-kindergarten programs are beneficial
