Introduction to histology and embryology;

1, histology and embryology is an important basic course. If you study hard, you will feel familiar with a lot of things you will learn in the future. It is divided into histology and embryology. Histology is clear and easy to understand, and exams account for a large proportion; Embryological examination accounts for a relatively small proportion.

This book consists of two parts. The first part is the outline of histology and embryology, and the second part is the real questions, which collect the real questions of postgraduate entrance examination in major universities and have reference answers and key points.

3. According to the teaching plan of the school, this course is 80 hours, including 68 hours of histology, 0/2 hours of embryology/kloc-,and the ratio of theory course to practice course is about 5: 4. Theoretical courses are mainly taught by teachers; Practice classes are conducted by observing specimens, watching slides and recording photos.

Abstracts of histology and embryology;

1. The basic tissue is a cell group composed of cells with similar morphology and structure and closely related functions. Human tissues can be divided into four basic tissues: epithelial tissue, connective tissue, muscle tissue and nerve tissue.

2. Epithelial tissue consists of a large number of closely arranged and regular cells and a small amount of intercellular substances. Epithelial tissue has the functions of protection, absorption, secretion and excretion. Most epithelial tissue covers the body surface, and the cavity surface of the organ is lined with cavities, which is called covered epithelium.

3. Epithelial cells show obvious polarity, that is, there are obvious differences in structure and function between the two ends of epithelial cells. The surface of epithelial cells facing the body surface or the cavity surface of cavity organs is called free surface; The surface opposite to the free surface is called the base surface.
