Document Summary
Midterm review questions: what are the 4 regions of the nervous system. Spinal, peripheral, cerebral, cerebellar/brainstem: what are the 3 main systems in the nervous system. Somatosensory, somatic motor, autonomic: where does the spinal cord start and end. Starts near l1-l2 foramen magnum and ends at the conus medullaris: when do the spinal nerves change routes. Above c7 they are superior, below c7 they are inferior (due to c8: purpose of cauda equina. Forms the spinal nerves of lumbar and sacrum: what tethers the sacrum/coccyx to the spinal cord. Filum terminalae (connective tissue: difference between gray and white matter. Gray matter consists of cell bodies and process information. White matter consists of myelinated neurons and axons and convey information: the cerebral cortex is covered in what. Gray matter: what are the cerebral lobes and their function.
