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.
Hyperhidrosis is a medical condition characterized by excessive sweating. People prone to sweaty palms may experience excessive sweating in other parts of the body. Sweaty palms may occur as a result of stress. Sweating is a device the body uses to help regulate its temperature. Excessive sweating may be caused by a myriad of health conditions.
