Preterm birth, also known as premature birth, is the birth of a baby at less than 37 weeks gestational age. These babies are known as preemies or premmies. Symptoms of preterm labor include uterine contractions which occur more often than every ten minutes or the leaking of fluid from the vagina.
The cerebral cortex plays a key role in memory, attention, perception, awareness, thought, language, and consciousness. The human cerebral cortex is 2 to 4 millimetres (0.079 to 0.157 in) thick. In large mammals, the cerebral cortex is folded, giving a much greater surface area in the confined volume of the skull.n the human brain more than two-thirds of the cerebral cortex is buried in the sulci. The cerebral cortex is gray matter, consisting mainly of cell bodies (with astrocytes being the most abundant cell type in the cortex as well as the human brain as a whole) and capillaries.
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.
