The first part of this lesson is dedicated to histology. We will deal with the respective cells of the four basic tissue types. You will also become more familiar with their various functions and their occurrence in the human body. Epithelial tissue, for example, separates individual areas of the body from each other or the organism as a whole from its environment. Connective and supporting tissue give the body shape and stability, while muscles enable movement and form the basis of various organ functions. The transmission of information is made possible by nerve tissue, so we will also look at the development and transmission of nerve impulses and their transmission from cell to cell. Only an understanding of the interplay between the different tissues makes it possible to understand the complex bodily functions of the human body.
In the second part of this lesson, you will learn the basics of human embryology, starting with the insemination of the ovum. Over several stages of cell division, precursors of various tissues mature, which later differentiate into the numerous tissue types. We will follow the individual stages of development through to the embryo.
At the end of this lesson, you will again be presented with a case report. This time you can expect an interesting case from neonatology.

In the previous chapter on cytology, you learned about the important basics of cytology. With this knowledge, you are well prepared for lesson 2, which deals with histology and embryology.
Histology is a branch of medicine and biology that deals with the structure and organization of tissues. Here it is the already known differentiated cells that form tissue by joining together. The so-called extracellular matrix is also involved here. These are protein structures that also provide additional stability and structure as "cement". Furthermore, inorganic compounds can be incorporated - as in bone tissue, for example. [1]
Embryology is the study of prenatal development, beginning with the fusion of the ovum with the sperm. The resulting cell then multiplies itself by dividing, forming complex tissue and a new organism as a whole. [1]
Learning goals
After completing this chapter, students will know and understand
- the development of the human organism from insemination of the ovum to the mature fetus
- the essential basics for the important field of reproductive biology
- the microscopically visualizable fine structure of the organs, connective tissue and their cells
