The combination of unfamiliar sophistications of language and of an involved technical subject. Their suggestions have greatly added to the accuracy and usefulness of this book. In this book care has been taken to ensure that the text provides all the information necessary for an intelligent understanding of the essential features of the development of various organs and tissues of the h u m a n body.
To obviate as many of these as possible a number of eminent anatomists were requested to read through the text. The difficulty has increased from year to year as there has been.
Care has been taken not to compress too many facts into an involved sentence. New words are clearly explained. Experience has shown that the treatment of the subject in most of these books is way above the head of the average medical student in India. At the same time. Fetal Membranes. The Placenta. The Pancreas and Spleen. The Liver and Biliary Apparatus.
Alimentary System—II: Alimentary System—I: Urogenital System.
The Nervous System. Cardiovascular System. Veins Part 4: Fetal Circulation Part 5: Hypophysis Cerebri. The usual method of cell division. Genes are made of such strands of DNA. The process is called spermatogenesis. The gametes resulting from meiosis have the haploid number of chromosomes After that we call it a fetus.
It is called meiosis. They produce gametes. The ovary is the female sex organ or gonad. The process is called oogenesis. Daughter cells resulting from a mitotic division are similar to the parent cell. Spermatogenesis and oogenesis are together called gametogenesis. They are located on chromosomes. The fused ovum and sperm form the zygote. The various gametes formed do not have the same genetic content. The follicle gradually increases in size and finally bursts and expels the ovum.
This process of shedding of the ovum is called ovulation. The process of conversion of a spermatid to a spermatozoon is called spermiogenesis Fig. The corpus luteum is formed by enlargement and transformation of follicular cells. The cells of the theca interna produce oestrogens Fig.
Stages of spermatogenesis are summarized in Fig. The corpus luteum secretes progesterone. Spermatozoa are derived from rounded spermatids. The follicle has a cavity filled with fluid Fig. The menstrual cycle is also divided into the follicular phase in which changes are produced mainly by oestrogens. The most obvious feature is a monthly flow of blood menstruation. This part is shed off and there is bleeding. Just before onset of menstruation. The menstrual cycle is influenced by oestrogens.
Both phases are of roughly equal duration. It undergoes a series of divisions clevage.
The morula now becomes a blastocyst. Another cavity appears on the endodermal side. It is made up only of ectoderm and endoderm. These layers are the epiblast and the hypoblast. This mesoderm forms the connecting stalk. This is the amniotic cavity. They are soon separated from the latter by extraembryonic mesoderm. This is the yolk sac. It has an inner cell mass covered by an outer layer of cells.
Here ectoderm and endoderm are not separated by mesoderm. The fertilized ovum is a large cell. A line drawn through the prochordal plate and the primitive streak divides the embryonic disc into right and left halves. Cells of the hypoblast become flattened and line the yolk sac. Intra-embryonic mesoderm shows three subdivisions Fig. A cavity called the intra-embryonic coelom appears in it and splits the mesoderm into a somatopleuric layer in contact with ectoderm and a splanchnopleuric layer in contact with endoderm Fig.
A wide strip of ectoderm overlying the notochord becomes thickened and forms the neural plate Fig. These are the head and tail folds Fig. The ground substance of the umbilical cord is made up of Wharton's jelly derived from mesoderm. The umbilical cord develops from the connecting stalk. Cells of the primitive knot multiply and pass cranially to form a rod-like structure reaching up to the prochordal plate.
The mesoderm next to the middle line is called the paraxial mesoderm. The embryonic disc. The pericardial cavity is derived from part of the intra-embryonic coelom that lies cranial to the prochordal plate Fig. It is divisible into foregut. This is the notochordalprocess. Most of the notochord disappears. After formation of the head fold the pericardial cavity lies ventral to the foregut. Lateral folds also appear. The developing heart lies ventral to the cavity Fig.
The allantoic diverticulum arises from the yolk sac before formation of the gut Fig. It contains the right and left umbilical arteries. The cord is covered by amnion. The liver and the diaphragm develop in relation to the septum transversum. The notochordal process undergoes changes that convert it first into a canal and then into a plate.
This is the notochord. A strip of mesoderm between the lateral plate mesoderm and the paraxial mesoderm is called the intermediate mesoderm.
Remnants remain as the nucleus pulposus of each intervertebral disc. The septum transversum is made of intra-embryonic mesoderm that lies cranial to the pericardial cavity Figs 5. The intra-embryonic coelom later forms the pericardial. As a result of these folds.

After formation of the head fold. After formation of the tail fold. The mesoderm in the lateral part of the embryonic disc is called the lateral plate mesoderm. It undergoes segmentation to form somites. The fully formed placenta is about six inches in diameter and about g in weight. They consist of a central core of cytotrophoblast covered by syncytiotrophoblast. It can cause problems during child birth. It consists of trophoblast one layer of cells resting on extra-embryonic mesoderm.
This is called implantation. All substances passing from mother to fetus and vice versa traverse this membrane. The villi are surrounded by maternal blood. Fetal blood circulates through capillaries in villi.
Textbook Of Embryology
Enlargement of the amniotic cavity obliterates the extra-embryonic coelom. From inside out these are extra-embryonic mesoderm. These are the amniotic cavity. A placenta attached lower down is called placenta praevia. Further enlargement of amniotic cavity obliterates the uterine cavity.
Fused amnion and chorion called membranes bulge into the cervical canal during child birth and help to dilate it. As the placenta enlarges. Some bones are formed by direct ossification of membrane intramembranous ossification.
In the case of long bones the shaft or diaphysis is formed by extension of ossification from the primary centre of ossification. Somites undergo division into three parts. Skeletal muscle is derived partly from somites and partly from mesenchyme of the region. Epithelium lining most of the urogenital tract is derived from mesoderm. The myelin sheaths of peripheral nerves are derived from Schwann cells. Cardiac muscle is formed from mesoderm related to the developing heart.
Mesenchyme is made up of cells that can give rise to cartilage. These are: Epithelia lining external surfaces of the body. Neurons and many neuroglial cells are formed in the neural tube. Lymphocytes are formed mainly in lymphoid tissues. Epithelium lining the gut. In growing bone the diaphysis and epiphysis are separated by the epiphyseal plate which is made up of cartilage.
Blood cells are derived from mesenchyme in bone marrow. Most smooth muscle is formed from mesenchyme related to viscera. Growth in length of a bone takes place mainly at the epiphyseal plate.
An area where ossification starts is called a centre of ossification. Secondary centres of variable number appear for bone ends. Want to Read Currently Reading Read. Error rating book.

It also forms the cerebellum. Thirdly, almost every step in development has been shown in a simple, easy to understand, illustration. The fourth ventricle is the cavity of the rhombencephalon. The malleus and incus are derived from Meckel's cartilage.. From inside out these are extra-embryonic mesoderm.
