lamina alaris (medicine) and metal point (sh)


lamina alaris (medicine)


lamina alaris -->
alar lamina of neural tube


The dorsal division of the lateral walls of the neural tube in the embryo; it gives rise to neurons relaying afferent impulses to higher centres; in the adult such neurons compose the sensory nuclei of the spinal cord and brainstem.

Synonym: lamina alaris, alar plate of neural tube, dorsolateral plate of neural tube, lamina dorsalis, wing plate.


metal point (sh)




or silverpoint

Method of drawing with a small sharpened metal rod
of lead, copper, gold, or most commonly silver
on specially prepared paper or parchment.

Silverpoint produces a fine gray line that oxidizes to a light brown; the technique is best suited for small-scale work. It first appeared in medieval Italy and achieved great popularity in the 15th century. Albrecht Durer and Leonardo da Vinci were its greatest exponents. It went out of Fashion in the 17th century with the rise of the graphite pencil but was revived in the 18th century by the miniaturists and in the 20th century by Joseph Stella.
