Document Summary

To the brain: afferent carries information from sensory receptors in skin to the brain. From the brain: efferent carries information from the brain to the neurons controlling leg muscles, causing a response. Axial/horizontal = on x-axis; view or the cut falls along the horizon; usually viewed looking down on the brain or from above. Sagital = y-axis; lengths from front to back, viewed from the side; a medial view. Coronal/frontal = frontal cortex; cut in the vertical plane, from the crown of the head down. Meninges: 3 layers: dura: (hard) tough double layer of fibrous tissue enclosing the brain in loose sack, arachnoid: (thin sheet of delicate connective tissue that follows the brain"s contours. Subarachnoid space space between pia and arachnoid layers; bring nutrients: pia matter: (soft) moderately tough membrane of connective tissue fibers that cling to the surface of the brain.
