The cortical reaction is a crucial process in fertilization, occurring shortly after a sperm penetrates the egg. It involves the release of enzymes from cortical granules in the egg's cytoplasm, leading to changes in the egg's membrane that prevent polyspermy, ensuring that only one sperm fertilizes the egg. This reaction also helps to initiate early developmental processes, contributing to the formation of the fertilization membrane. Overall, the cortical reaction is vital for successful reproduction and the proper development of the embryo.

What is periderm in secondary growth?
Secondary growth in cortical region forms secondary cortex inside and periderm outside the cortical cambium

What types of cells make up cortical region?
The cortical region primarily consists of neurons, which are the main cells responsible for processing information in the brain. Additionally, glial cells such as astrocytes and oligodendrocytes provide support and insulation to neurons in the cortical region.

polyspery
What are cortical deficits?
Lacunar strokes LACK cortical deficits. Exactly what are cortical symptomes, I do not know. =-(
What is cortical thickening on femur?
Cortical thickening on the femur refers to the increased density or thickness of the outer layer of bone in the thigh bone. This can be a result of conditions like osteopetrosis, chronic overload from physical activity, or healing response to stress fractures or other injuries. It can be seen on imaging studies like X-rays or CT scans.
What is the function of the cortical artery?

Which vessels supply the cortical tissue of the kidney with blood?
cortical radiate arteries
What does cortical defect mean in medical terms?
A cortical defect is an abnormality in the outer shell.
What is the function of the cortical reaction?
The cortical reaction is a process that occurs in fertilization where the released enzymes and calcium ions cause changes in the egg's zona pellucida to prevent polyspermy, the entry of multiple sperm into the egg. This helps ensure that only one sperm fertilizes the egg, which is essential for successful development.
What is the definition of cortical?
Cortical-- Regarding the cortex, or the outer layer of the brain, as distinguished from the inner portion.
What is the treatment for cortical atrophy of the brain?
There is no treatment for cortical atrophy of the brain; just support and nursing care.
What part of the brain is the cortical structure?
The outer layer of the brain is the cortex and would be referred to as a cortical structure.
