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.
The most common diseases to cause excessive sweating are diabetes and hyperthyroidism. Diabetes mellitus is a disease of poor glucose (sugar) control. Over time, diabetes disrupts the proper function of the ANS. Diabetes is also associated with obesity, which itself can cause excessive sweating. An easy way to find out if you have diabetes is to have your blood glucose (sugar) checked by your primary doctor with a simple blood test.
