Answer 1

week 3 to 8 most important development period

Question 2

gastrulation initiates:

Answer 2

embryonic period

Question 3

fertilization should take place in the:

Answer 3

Ampula of the uterine tube

Question 4

female egg is unarrested once:

Answer 4

fertilization

Question 5

within the zona palucida, the cells continue to divide and are called:

Answer 5

blastomeres (mercy)

Question 6

at time of implantation, the embryo is called:

Answer 6

blastocyst

Question 7

just before implantation, the embryo:

Answer 7

erupts from zona pallucida

Question 8

neurulation

Answer 8

refers to the folding process in vertebrate embryos, which includes the transformation of the neural plate into the neural tube. The embryo at this stage is termed the neurula.

Question 9

sclerotome

Answer 9

somite derivative: Embryology. the part of a mesodermal somite contributing to the development of the vertebrae and ribs.

Question 10

dermatome

Answer 10

somite derivative: A dermatome is an area of skin in which sensory nerves derive from a single spinal nerve root

Question 11

myotome

Answer 11

somite derivative: A myotome is the group of muscles that a single spinal nerve root innervates. Similarly a dermatome is an area of skin that a single nerve innervates.

Question 12

epimere

Answer 12

myotome derivative (somite derivative): the dorsal portion of a somite, from which are formed muscles innervated by the dorsal ramus of a spinal nerve.

Question 13

hypomere

Answer 13

myotome derivative (somite derivative): one of the ventrolateral portions of the fusing myotomes in embryonic development, forming muscles innervated by the ventral rami of the spinal nerves.

Question 14

dorsal ramus inervates:

Answer 14

epimere

Question 15

ventral ramus inervates:

Answer 15

hypomere

Question 16

lateral plate mesoderm:

Answer 16

the peripheral portion of intraembryonic mesoderm that is continuous with the extraembryonic mesoderm beyond the margins of the embryonic disc; it forms the somatic and splanchnic mesoderm between which develops the intraembryonic celom.

Question 17

somtapleuric

Answer 17

derived from the lateral plate mesoderm, and form the body wall

Question 18

splanchnopleuric

Answer 18

derived from the lateral plate mesoderm, and forms the guts

Question 19

intraembryonic coelom

Answer 19

In the development of the human embryo the intraembryonic coelom (or somatic coelom) is a portion of the conceptus forming in the mesoderm during the third week of development. During the third week of development, the lateral mesoderm splits into a dorsal somatic mesoderm (somatopleure) and a ventral splanchnic mesoderm (splanchnopleure). The resulting cavity between the somatopleure and splanchnopleure is called the intraembryonic coelom

Question 20

During the third week of development, the lateral mesoderm splits into a dorsal_______ and a ventral ______ The resulting cavity between the _______ and ________ is called the intraembryonic coelom

Answer 20

During the third week of development, the lateral mesoderm splits into a dorsal somatic mesoderm (somatopleure) and a ventral splanchnic mesoderm (splanchnopleure). The resulting cavity between the somatopleure and splanchnopleure is called the intraembryonic coelom

Question 21

somatic mesoderm on the ventral side of the developing embryo develops into the ________

Answer 21

septum transversus

Question 22

the _______ is angled back because it grew from ventral to dorsal as the embryo enlarges

Answer 22

diaphram

Question 23

the septem transversus grows from the ventral side of the developing embryo to divide the _______

Answer 23

intraembryonic coelom

Question 24

the ______ membrane that grow from the dorsal side to meet up with the septum transversum

Answer 24

pleuroperitoneal membrane

Question 25

pericardioperitoneal cavity is the area closed off by the:

Answer 25

septum transversum and the pleuroperitoneal membrane

Question 26

CDH:

Answer 26

The majority of CDHs occur on the left side. The hole allows the contents of the abdomen (stomach, intestine, liver, spleen, and kidneys) to go up into the fetal chest

Question 27

pleuropericardial folds

Answer 27

separates mediastinum from pleural cavities

Question 28

laryngotracheal diverticulum

Answer 28

the endodermal diverticulum from the floor of the caudal end of the primordial pharynx; it gives rise to the epithelium and glands of the bronchial tree. After this diverticulum separates from the foregut, it is referred to as a tube.
