The story is told by Harrison Shepherd, an apparently unremarkable half-American, half-Mexican boy born to a peripatetic mother in 1920s rural Mexico. It is an admirably ambitious work spanning a fascinating period of history, but it lacks the strong characterisation that made The Poisonwood Bible such a success. It does not store any personal data.The Lacuna, her first novel for 10 years, takes in the Mexican revolution, the exile of Trotsky in Mexico City, the First World War and the communist witch-hunts in 1950s America.

Principles of Inheritance and Variation.New Questions and Answers and Forum Categories Fine cytoplasmic processes extend for a certain distance into the canaliculi and these canaliculi which are irregularly oval on the flat and biconvex on the edge radiate out from the lacunae.Īs osteoblast had numerous slender cytoplasmic processes, small cinaliculi extend from each lacuna out in the osseous matrix, osteocyte is separated by the matrix from each other and connects indirectly with each other by canaliculi. The osteocyte has got no active synthesizing properties. The cytoplasm of osteocyte is faintly stained with basic dye and contains lipid droplets, granules and also glycogen. This cell has small ovoid, highly chromatic nucleus. Thus the osteocyte remains trapped within the lacuna (small lake).
Osteoblast becomes trapped within its own secretory material-the matrix. It is the trapped or imprisoned osteoblast within the organic matrix. The cytoplasm has got affinity towards basic dye due to presence of a large amount of rough-surfaced endoplasmic reticulum with its associated ribosomes. For its important function of calcification, bone-forming osteoblast possesses a rich concentration of enzyme, alkaline phosphatese in the cytoplasm. The cell secretes the bone matrix and thus calcification takes place.
