The arachnoid mater covering the brain is referred to as the arachnoidea encephali, and the portion covering the spinal cord as the arachnoidea spinalis.. The arachnoid and pia mater are sometimes considered as a single structure, the leptomeninx, or the plural version, leptomeninges. (Lepto- from the Greek root meaning thin). Similarly, the dura in this situation is called the pachymeninx.
Sweaty Hands Excessively sweaty hands are caused by the condition known as hyperhidrosis. Palmer (palm of the hand) hyperhidrosis is caused by a hyperactive sympathetic nervous system causing sweat glands in the hands to produce an excessive quantity of sweat.
People usually tend to sweat more when the temperatures are warm, when they practice exercises or when being put in the response to some specific situations that make them angry, embarrassed, nervous or afraid. In fact, some of the common causes of sweaty hands can include stress, nervousness, anxiety and depression. People experiencing this condition are more likely to have overactive sweat glands . Excessive sweating of the palms can result in some certain types of infections including bacterial and fungal infections or even the irritation of the skin .
