Document Summary

Stations 1 anatomical terminology and intro to meninges. Anatomical position standing erect with arms at the side and palms facing forward. Terms to remember: superior (cranial) top. Ipsilateral on same side, left wrist is ipsilateral to left arm: contralateral opposite sides of the body. Meninges three connective tissue membranes that lie external to the brain and spinal cord, they protect the brain, enclose and protect the blood vessels that supply the cns, and contain the cerebral spinal fluid. Falx cerebri splits the brain left versus right at the top, it lies in the longitudinal fissure, between the cerebral hemispheres. Falx cerebelli continuing inferiorly from the posterior part of the falx cerebri, also a vertical partition which along the cerebellum. Tentorium tents over the cerebellum (horizontal), it lies in the transverse fissure between the cerebrum and cerebellum. These are considered the infoldings of the dura mater. The major divisions of the central nervous system include: cerebrum, cerebellum, diencephalon, brainstem, spinal cord.
