The meninges (from the Greek meninx, meaning membrane) cover and protect the brain and spinal cord. The meninges have three layers: 1) the dura mater, 2) the arachnoid, and â¦ 3) the pia mater. The dura mater is the outermost layer covering the central nervous system.he innermost layer of the meninges is the pia mater. The pia mater is firmly attached to the neural tissue of the spinal cord and brain. Cerebrospinal fluid fills the space between the pia matter and the arachnoid membrane. Most of the blood vessels that supply blood to the central nervous system are in the pia mater.
According to Aristotle, tragedy has six main elements: plot, character, diction, thought, spectacle (scenic effect), and song (music), of which the first two are primary.
The dialogue helps move the action of the play along. â¢ Music/Rhythm: While music is often featured in drama, in this case Aristotle was referring to the rhythm of the actors' voices as they speak. â¢ Spectacle: This refers to the visual elements of a play: sets, costumes, special effects, etc.
