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.
Fortunately, most of the time having constantly sweaty hands is not a sign of a serious medical problem or illness. Rather, it just means that you have over active sweat glands, which is largely determined by your genetics. Over active sweat glands most often can occur in the feet, the palms of the hands, or the armpits. The medical term for over active sweat glands is hyperhidrosis.
