Remember that the choroid plexus is the specialized capillaries that make the cerebrospinal fluid. Dura Mater Outermost layer of the meninges. Composed primarily of tough, white connective tissue. A thin, netlike membrane located between the dura and pia maters. It spreads over the brain and spinal cord.
Subarachnoid space lies between the arachnoid mater and pia mater.
The pia mater is attached to the surfaces of the brain and spinal cord. Lateral spinothalamic tract Conduct the sensory impulses of pain and temperature Anterior spinothalamic tract Conduct the sensory impulses of touch and pressure Spinocerebellartracts Conduct sensory impulses from the trunk and legs to the cerebellum that are necessary for balance and coordination Descending Corticospinal tracts Conduct motor impulses from the brain to the spinal nerves to skeletal muscles. Control voluntary movements Reticulospinal tracts Conduct motor impulses from the brain to the muscles and skin. Control muscular toneand activity of the sweat glands. Rubrospinal Carry motor impulses from the brain to skeletal muscles and are involved with muscular coordination and the control of posture Table 6.
