Cleavage by Tauqeer Ahmad
The document summarizes the process of cleavage in early embryonic development. It describes how the zygote undergoes rapid cell divisions called cleavage to form a solid ball of cells called a morula. The morula then develops a fluid filled cavity called a blastocoel, forming the blastocyst stage. Within the blastocyst, the cells arrange into two layers - an inner cell mass that will become the embryo, and an outer trophoblast layer that will provide nutrition and allow implantation in the uterus.

It describes the embryonic and fetal periods, the stages of development including fertilization, cleavage, gastrulation, and organogenesis. Key events like formation of the three germ layers and development of the placenta, amnion, chorion, and allantois are summarized. The roles of hormones and growth of the major organs by the third trimester are highlighted. Birth and the role of oxytocin in labor are briefly mentioned.
Early embryonic devlpmnt
Embryonic development begins with fertilization forming a zygote, which undergoes rapid cell division through cleavage. This forms a hollow ball of cells called a blastula. The blastula then undergoes gastrulation where the cells rearrange into three germ layers - ectoderm, endoderm, and mesoderm. Organogenesis then transforms these germ layers into complete organs through a series of organized processes.
Other patterns of organization
This document discusses different levels of biological organization, including unicellular, diploblastic, and triploblastic. It describes the three main patterns of triploblastic organization: acoelomate, pseudocoelomate, and coelomate. The presence or absence of a body cavity distinguishes these patterns and provides advantages like more room for organs and improved gas exchange.
Zygote 2
The document summarizes the key stages of embryonic development from fertilization to differentiation of organs. It begins with fertilization, where the genetic material from sperm and egg cells combine to form a zygote. The zygote then undergoes cleavage, forming a solid ball of cells called a morula. Further cleavage results in blastulation and the formation of a hollow ball of cells called a blastula or blastocyst. During gastrulation, the blastula undergoes differentiation into three embryonic layers - ectoderm, endoderm, and mesoderm. Neurulation follows, forming the neural tube from neural folds. Finally, organogenesis occurs as organ rudiments develop and differentiate into mature organs.

The zygote is a single eukaryotic cell formed by the fusion of an egg and sperm cell, containing a combined genome to form a new individual. It undergoes cleavage, forming a solid ball of cells called a morula. Further divisions form a hollow ball of cells called a blastula or blastocyst, containing an inner cell mass. During gastrulation, the blastula undergoes differentiation into three germ layers - ectoderm, endoderm and mesoderm. This forms the basic structure of the embryo, which then undergoes organogenesis and differentiation to develop specialized organs and tissues.

1) Fertilization occurs when a sperm fuses with an egg, forming a zygote. The zygote undergoes cell division and develops into a blastocyst over about a week.
2) The blastocyst implants in the uterus and undergoes gastrulation and neurulation, forming the three germ layers and establishing the basis for the nervous system.
3) Development continues with the formation of organs and tissues over nine months until birth, when contractions push the baby through the birth canal.
Cleavage to Three Germ Layers
The document describes cleavage, which is the repeated division of the zygote into blastomeres without growth. In humans, cleavage occurs in the fallopian tube and results in a solid ball of cells called a morula. The morula undergoes cavitation to form a blastula with an inner cell mass and outer trophoblast cells. The blastula implants in the uterus and the inner cell mass then undergoes gastrulation to form the three germ layers - endoderm, ectoderm, and mesoderm - which develop into various tissues and organs.

Embryology seminar
Embryology is the study of prenatal development to understand how anatomical structures form. The major events of the first week include conception, formation of the zygote, cleavage into blastomeres, formation of the morula and blastocyst. The blastocyst undergoes implantation in the endometrium between days 6-7. This involves apposition, adhesion, penetration and invasion. The trophoblast differentiates and the inner cell mass forms the embryo proper. During the embryonic period from weeks 4-8, the three germ layers form and all major structures and organs develop. By the end of the embryonic period at 8 weeks, the embryo has distinct human form and features.
Cleavage 1
This document discusses cleavage, the process by which a fertilized egg undergoes cell division to form a multicellular embryo. It describes key terms related to cleavage such as furrow, morula, blastula, blastocoel, blastocyst, blastomere, and gastrula. It explains different types of cleavage including holoblastic, where the cleavage furrow extends through the entire egg, and meroblastic, where cleavage is incomplete. Within these categories are subtypes like radial, spiral, bilateral, discoidal, and superficial cleavage that describe the orientation and extent of the cell divisions. Factors like the amount and distribution of yolk in the egg influence the cleavage pattern.

Germ Layers Ppdf
The document discusses the formation of germ layers from the fertilized ovum through the blastocyst stage. Key points include:
1) Cleavage of the ovum leads to the formation of the morula with an inner cell mass and outer trophoblast layer. Further development creates the blastocyst containing an inner cell mass surrounded by fluid.
2) The inner cell mass of the blastocyst gives rise to the three germ layers - endoderm, ectoderm, and mesoderm. The trophoblast gives rise to extraembryonic structures.
3) Structures that form include the amniotic cavity, yolk sac, and extraembryonic mesoderm which
BIO420 Chapter 01
The document summarizes key stages in animal development from fertilization through organogenesis. It begins with fertilization and cleavage, followed by gastrulation where the three germ layers (endoderm, mesoderm, ectoderm) are formed. During organogenesis, organs develop from the germ layers. Metamorphosis may also occur to transition organisms like frogs from immature to sexually mature forms. Examples are provided of developmental processes in frogs and other model organisms like fruit flies and plants. Cell behavior and patterning during these stages are also discussed.
Fertilization and Development
Internal fertilization involves the male releasing sperm into the female reproductive tract, increasing chances of fertilization. After fertilization, the zygote undergoes cleavage and develops into a morula, blastula and gastrula. The gastrula forms the three germ layers - ectoderm, endoderm and mesoderm - which give rise to the organs of animals. In humans, the blastocyst implants in the uterus and develops a placenta and umbilical cord to exchange gases and nutrients with the mother.
Cleavage: Definition, types, and mechanism
Early embryonic development involves a series of key stages:
1. Cleavage - The fertilized egg undergoes rapid, synchronized cell divisions without growth to form a solid ball of cells called a morula.
2. Blastulation - Cell divisions continue and a fluid-filled cavity called a blastocoel forms, establishing polarity and transforming the morula into a hollow ball of cells called a blastula.
3. Gastrulation - Cells migrate and rearrange through morphogenetic movements to form the three primary germ layers - ectoderm, endoderm, and mesoderm - establishing the body plan of the embryo.
pre natal development
The document discusses the stages of prenatal human development. It is divided into 3 primary stages: the germinal stage from conception to implantation, the embryonic stage from weeks 2-8, and the fetal stage from week 9 until birth. The germinal stage involves fertilization, cleavage, blastulation and implantation. The embryonic stage includes formation of the embryonic disc, gastrulation, neurulation and organogenesis as major organs begin to form.
Embryology-Part-1 (1) (1).pdf NBBVVVVHJM
Embryogenesis refers to the development of an embryo. Key events include fertilization where an egg and sperm fuse to form a zygote, cleavage where the zygote rapidly divides through mitosis, gastrulation where the single-layered blastula reorganizes into three germ layers, and organogenesis where organs develop. Embryology is the study of developmental events during the prenatal stage including descriptive, comparative, experimental, chemical and teratology approaches. The development of the placenta begins with implantation of the blastocyst in the endometrium and formation of the decidua and chorionic villi for nutrient exchange.
Gastrulation
Gastrulation is the process by which the three germ layers (ectoderm, mesoderm, endoderm) are formed in the embryo through cell movements. In amphibians, cells from the blastula's outer layer invaginate and involute to form the inner layers. The blastocoel is replaced by the archenteron. In birds, the epiblast and hypoblast layers are initially formed; the epiblast gives rise solely to the three germ layers. Gastrulation rearranges cells into layers that will develop into tissues and organs.

The document summarizes the key stages of fertilization and embryonic development in humans. It describes:
1) Fertilization occurring when the sperm fuses with the ovum in the fallopian tube to form a zygote, which undergoes cell division over several days to become a morula and then a blastocyst.
2) The blastocyst implants in the uterine wall and the trophoblast develops to form the placenta, while the inner cell mass forms the embryo and its structures.
3) It outlines the major developmental milestones from weeks 3-31, including organ formation, growth of limbs and senses, and increasing activity of the fetus.

Cleavage is the repeated mitotic division of the zygote that results in a multicellular mass of smaller cells called blastomeres. It begins immediately after fertilization and continues as the zygote passes through the uterine tube. During cleavage, the zygote undergoes a series of divisions, developing from a 2-cell stage to a 4-cell stage and so on. By the 16-cell stage it has formed a structure called a morula, which then develops a fluid-filled cavity to form a blastocyst containing an inner cell mass and outer trophoblast cells. Implantation occurs when the blastocyst attaches to the uterine wall around 6-7 days after fertilization.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Gastrulation.docx
- 1. Gastrulation – Embryology / Biology gastrula Definition The gastrula is the embryo stage that follows the blastula. It forms a shape having a hollow cup-shapethat has three cell layers. For more clear and detailed, visit https://oke.io/wmoWpjIc Overview of Gastrula Gastrula is the early multicellular embryo that consists of germinal layers from which the body's a number of organs are formed later. The development of gastrula happens from the blastula that is a single- layered hollow ball of cells. The structure of the blastula is formed becauseof the repeated cleavage or cell division of the fertilized egg. Following the cleavage, there is a duration of development where the motion of cells occurs. A multicellular organism typically has a concentric arrangement of bodytissues. The three sorts of embryonic cell layers additionally recognized as the germinal layers that form these grownup tissues. The ectoderm is the outer layer, whereas the mesoderm is the middle layer, and the endoderm is the innermost layer. In the process ofgastrulation, the blastula cells reshuffle to form the three germinal
- 2. layers that later form various bodyorgan systems. In gastrulation, there is an invagination or an inward motion of the blastula cells. Hence the spherical embryo gets transformed to form the double-walled cup that is also recognized as gastrula. The blastula's involuted phase that lines the double-walled cup's interior forms the mesoderm and the endoderm, whereas the remaining cells on the cup's exterior create the ectoderm. The ectoderm is additionally known as the outer layer that forms the pores and skin overlaying of the animal and also its sense organs and nervous system.
