|---|---|---|---|---|---|
| Indeterminate cleavage | Indeterminate cleavage results in cells that can still develop into complete organisms. These create humans.
🗑
|
||||
| Cleavage | A zygote undergoes rapid mitotic cell divisions
🗑
|
||||
| Determinate cleavage | Determinate cleavage results in cells that are committed to differentiating into a certain type of cell.
🗑
|
||||
| Blastula | Blastulas are characterized by the presence of a hollow, fluid-filled inner cavity known as a blastocoel. It consists of a "trophoblast" and "inner cell mass"
🗑
|
||||
| Trophoblast | Trophoblast cells surround the blastocoel and give rise to the chorion and later the placenta
🗑
|
||||
| Inner cell mass | The inner cell mass protrudes into the blastocoel and gives rise to the organism itself.
🗑
|
||||
| Implantation | Planting an embryo into the endometrium, progesterone provides the fertile soil by promoting proliferation.
🗑
|
||||
| Gastrulation | The generation of three distinct cell layers
🗑
|
||||
| Archenteron | The cavity created by the deep invagination, which later develops into the gut
🗑
|
||||
| Blastopore | The opening of the archenteron. In deuterostomes, such as humans, the blastopore develops into the anus. In protostomes, it develops into the mouth.
🗑
|
||||
| Ectoderm | Attract-oderm:
Integument (including the epidermis, hair, nails, epithelium of the nose, mouth, and anal canal), lens of the eye, and the nervous system. Adrenal MEDULLA
🗑
|
||||
| Mesoderm | Means-oderm (get from place to place):
Musculoskeletal system, circulatory system, excretory system, gonads, muscular and connective tissue coats of the digestive and respiratory systems. Adrenal CORTEX
🗑
|
||||
| Endoderm | End-dernal (mouth ---> anus and lungs):
Epithelial linings of digestive and respiratory tracts and parts of the liver, pancreas, thyroid, bladder, and distal urinary and reproductive tracts.
🗑
|
||||
| Neurulation | Development of the nervous system.
🗑
|
||||
| Placenta | The organ where nutrient, gas, and waste exchanges occur.
🗑
|
||||
| Amniotic Fluid | A shock absorber during pregnancy and labor (similar to a car's airbags)
🗑
|
||||
| Yolk sac | The site of early blood vessel development
🗑
|
||||
| Chorionic villi | Grow into the placenta and support maternal-fetal gas exchange
🗑
|
||||
| Foramen ovale | Connects the right atrium to the left atria
🗑
|
||||
| Ductus arteriosus | Connects the pulmonary artery to the aorta to shunt leftover blood that doesn't go through the foramen ovale
🗑
|
||||
| Ductus venosus | shunts most of the left umbilical vein blood flow directly to the inferior vena cava. Thus, it allows oxygenated blood from the placenta to bypass the liver.
🗑
|
||||
| Umbilical arteries | (Away from the fetus)
Carry deoxygenated blood away from the fetus
🗑
|
||||
| Umbilical vein | (To the fetus)
Carry oxygenated blood to the fetus
🗑
|
||||
| First Trimester | Most of the organs have formed, the brain is fairly developed, and the embryo is referred to as a fetus
🗑
|
||||
| Second Trimester | The fetus grows. It begins to move around in the amniotic fluid, its face appears, and its toes and fingers elongate
🗑
|
||||
| Third Trimester | Continued rapid growth and further brain development. Antibodies are transported by highly selective active transport from the mother to the fetus.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
