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.
Certain conditions such as diabetes can cause damage to the nerves, resulting in pain, numbness, or tingling of the arms and legs. This phenomenon, known as peripheral neuropathy, can also sometimes cause finger pain. Infection of the skin or other tissues of the finger is a less common cause of finger pain. Carpal tunnel syndrome initially causes numbness and tingling in the hand, but as it progresses, it may cause cramping or burning in the fingers. Medically Reviewed by a Doctor on 2/2/2015.
