Connective tissue(CT) is one of the four basic types of animaltissue, along with epithelial tissue, muscle tissue, and nervous tissue. It develops from the mesoderm. Connective tissue is found in between other tissues everywhere in the body, including the nervous system. In the central nervous system, the three outer membranes (the meninges) that envelop the brain and spinal cord are composed of connective tissue. They support and protect the body. All connective tissue consists of three main components: fibers (elastic and collagenous fibers), [1]ground substance and cells. Not all authorities include blood[2] or lymph as connective tissue because they lack the fiber component. All are immersed in the body water.
The cells of connective tissue include fibroblasts, adipocytes, macrophages, mast cells and leucocytes.
The term "connective tissue" (in German, Bindegewebe) was introduced in 1830 by Johannes Peter Müller. The tissue was already recognized as a distinct class in the 18th century
Holidays in the country.
Summer is my favorite time of the year. Summer holidays are the longest. This year I spent my summer holidays in the country. Most of the time I walked, cycled, spent time with my friends. When the weather was hot, we went to the river. In the evenings, I helped my mother water the beds in the garden. I liked my summer holidays very much.
ПЕРЕВОД: Каникулы в деревне.
Лето — мое любимое время года. Летние каникулы самые длинные. В этом году я провел летние каникулы в деревне. Большую часть времени я гулял, ездил на велосипеде, проводил время с друзьями. Когда погода была жаркая, мы ходили на реку. По вечерам я маме поливать грядки в саду. Мне очень понравились мои летние каникулы.
