GENERAL HISTOLOGY

Detailed explanation-1: -Schwann is most famous for his contributions to the cell theory . Schwann concluded three things that became vital components of the cell theory. First, Schwann concluded that both plants and animals were composed of cells.

Detailed explanation-2: -The classical cell theory was proposed by Theodor Schwann in 1839. There are three parts to this theory. The first part states that all organisms are made of cells. The second part states that cells are the basic units of life.

Detailed explanation-3: -His research led to the discovery of the cell that produces the myelin sheath that envelops the axon. In honor of his contribution, this was later eponymously named the Schwann cell [3, 7, 9]. He also found that during embryonic development individual cells unite to form the muscle fiber [10].

Detailed explanation-4: -In it Schwann declared that “All living things are composed of cells and cell products". He drew three further conclusions about cells, which formed his cell theory or cell doctrine. The first two were correct: The cell is the unit of structure, physiology, and organization in living things.

Detailed explanation-5: -Matthias Jacob Schleiden was a German botanist who, with Theodor Schwann, cofounded the cell theory. In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure.
