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.
Many rheumatic conditions and diseases may cause finger bumps. Osteoarthritis, the most common form of arthritis, often affects the hands. When it does so it often is associated with local inflammation of the distal inter-phalangeal joints (DIP or last row) and proximal inter-phalangeal joints (PIP or next to last row).out may cause inflammation of the interphalangeal joints of the fingers. When this occurs, it may be indistinguishable from a flare of osteoarthritis. Middle-aged (post-menopausal) or elderly women on diuretic therapy are particularly prone to developing this. Gout may also cause soft tissue bumps.
