Thus granule release can also be promoted by the ionophore A23187 (ref. 4) Periosteal reaction results when cortical bone reacts to one of many possible insults. Tu-mor, infection, trauma, certain drugs, and some arthritic conditions can elevate the perioste-um from the cortex and form various patterns of periosteal reaction (Fig. 1).

Fibrous cortical defects typically occur in children (usually 2-15 years), and indeed are one of the most common benign bony lesions, which combined with non-ossifying fibromas are seen in up to 40% of skeletally immature children/adolescents 3.

The cortical reaction is a method triggered during fertilization by cortical granules release from the egg, and it helps to prevent the multiple sperm from mixing

TMS can evoke directly measurable physiological responses that produce maps from only those cortical spots that are mandatory for the observed reaction. However, little is known about how contextual odors may lead to modulation of cortical processing in response to facial expressions.

Cortical granules contain a mixture of enzymes, including several proteases, which diffuse into the zona pellucida following exocytosis from the egg. Describe the cortical reaction. The cortical reaction occurs in fertilisation when a sperm cell unites with the egg's plasma membrane, (zona reaction).This reaction leads to a modification of the zona pellucida that blocks polyspermy; enzymes released by cortical granules digest sperm receptor proteins ZP2 and ZP3 so that they can no longer bind sperm, in mammals.

Cortical rotation's significance as a symmetry breaking event is underlined when we see what happens if we prevent it. Brief treatments of frog ( Xenopus laevis ) fertilized eggs with agents that affect microtubule polymerization prevent cortical rotation and result in a "ventralized" embryo - that is, it has ventral structures but lacks dorsal structures including those that would build a spinal cord.
