Mental Scale

The mental scale, or mental, in snakes and other scaled reptiles refers to the median plate on the tip of the lower jaw. It is a triangular scale that corresponds to the rostral of the upper jaw. The reference to the term 'mental' comes from the mental nerve which addresses the chin and lower jaw in animals. In snakes, the shape and size of this scale is sometimes one of the characteristics used to differentiate species from one another.

Famous quotes containing the words mental and/or scale:

    ... in doing our psychology, we want to attribute mental states fully opaquely because it’s the fully opaque reading which tells us what the agent has in mind, and it’s what the agent has in mind that causes his behavior.
    Jerry Alan Fodor (b. 1935)

    I don’t pity any man who does hard work worth doing. I admire him. I pity the creature who does not work, at whichever end of the social scale he may regard himself as being.
    Theodore Roosevelt (1858–1919)
