The oldest, and most commonly used, is the USDA Zone Hardiness map which calculates 11 zones and tells what level of winter cold a plant could experience in a location. Seattle falls into zone 8b with expected winter minimums of 15 to 20.
Motor cortex. (Redirected from Secondary motor cortex) The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements. Classically the motor cortex is an area of the frontal lobe located in the posterior precentral gyrus immediately anterior to the central sulcus.
An overview of the primary motor cortex function tells us that various regions of the cerebral cortex are involved in planning of the voluntary motor functions in the human body.The primary motor cortex function also includes the subsequent processes like controlling and executed the planned motor action.he primary motor cortex function is to generate the neural impulses that are required for the execution of the motor activities in the human body. The other parts are grouped under the category of secondary motor cortex and these include the posterior parietal cortex, premotor cortex and supplementary area cortex.
