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.
The motor cortex of the brain is a region in the posterior part of the frontal lobe that controls voluntary movement.Neurons in this region of the brain send signals down the spinal cord to the muscles to coordinate movements.he motor cortex works in harmony with the premotor areas in the frontal cortex to plan out and execute voluntary movement. It is made up of Betz cells, special neurons that send axons down into the spinal cord. These axons communicate with spinal neurons by synaptic transmission.
