{During embryonic disc folding in week 3 only the ectoderm layer folds ventrally left, right and above and below the notochord.
+
{Which of the following answers describes the human embryonic period:
 
|type="()"}
 
|type="()"}
- &nbsp; true
+
- &nbsp; the period before replacement of cartilage within the humerus by bone marrow begins
+ &nbsp; false
+
|| Correct! But not the only correct answer to appear here. In 1949 the embryologist George Streeter used the replacement of cartilage within the humerus by bone marrow as an arbitrary definition of the embryo to fetus transition. "If the onset can be recognized in a given specimen, that specimen is straightway classed as a fetus."
|| During folding in the third week all three germ cell layers (ectoderm, mesoderm and endoderm) fold together ventrally as described.
+
- &nbsp; a discrete entity that has not yet reached 8 weeks of development since the first mitotic division
 +
|| Correct! But not the only correct answer to appear here. This is part of the biological definition from the Australian National Health and Medical Research Council (NHMRC) discussion paper (2006).
 +
- &nbsp; the developmental period up to 8 post-ovulatory weeks
 +
|| Correct! But not the only correct answer to appear here. This is part of the biological definition from the Australian National Health and Medical Research Council (NHMRC) discussion paper (2006).
 +
- &nbsp; the period when more than 90% of the more than 4,500 named structures of the adult body have appeared
 +
|| Correct! But not the only correct answer to appear here. This is a historical definition ([https://www.ncbi.nlm.nih.gov/pubmed/400868 1979], [[Book - Developmental Stages In Human Embryos|1989]]) of the human embryonic period.
 +
+ &nbsp; all of the above are correct
 +
|| Correct! All of the above descriptions are correct descriptions of the human embryonic period.
  
{Which of the following is the most correct statement about the primitive streak:
+
{In human development, the first trimester is best described as:
 
|type="()"}
 
|type="()"}
- &nbsp; extends from the primitive node to the parachordal plate
+
- &nbsp; the period when organs begin to function
- &nbsp; is a primary inducer during organogenesis
+
|| Incorrect! The first trimester the period of organogenesis, when organs begin to develop.
+ &nbsp; is a site of migration of epiblast cells to form the mesoderm
+
+ &nbsp; the embryonic period and the beginning of the fetal period
|| The primitive streak is a site of migration of epiblast cells to form firstly endoderm and then the mesoderm.
+
|| Correct! The embryonic period finishes at 8 weeks ({{GA}} 10 weeks) and the beginning weeks of the fetal period, week 9-10 ({{GA}} 11-12 weeks).
- &nbsp; persists as the parachordal plate
+
- &nbsp; the least critical time of human development
 +
|| Incorrect! This is the '''most {{critical period}}''' of human development, where exposure to teratogens can lead to developmental abnormalities (anomalies, congenital).
 +
- &nbsp; the beginning of fetal sensory function
 +
|| Incorrect! Sensory function is dependent upon central nervous system development that occurs later in the fetal period. Note that while sensory components develop during the first trimester, many are not completed until the fetal period or postnatally.
 
- &nbsp; all of the above are correct
 
- &nbsp; all of the above are correct
 +
|| Incorrect! Clearly some of the options are not accurate descriptions of first trimester development. The correct answer is "the embryonic period and the beginning of the fetal period". The embryonic period finishes at 8 weeks ({{GA}} 10 weeks) and the beginning weeks of the fetal period, week 9-10 ({{GA}} 11-12 weeks).
  
 +
{Which of the following limb development processes has not completed by the end of the first trimester:

|type="()"}

+ &nbsp; ossification of the limb long bones
 +
|| Correct! Ossification of the limb long bones has not yet completed. [[Musculoskeletal_System_-_Limb_Development#Limb_Bone|Limb Bone Development Timeline]] and [[Musculoskeletal_System_-_Bone_Development_Timeline#Historic_Limb_Data|Historic Limb Data]].
 +
- &nbsp; rotation of the upper limb

|| Incorrect! The rotation of the upper limb occurred during [[BGDA_Practical_7_-_Week_8#Limbs|week 8]].

|| Incorrect! The apoptosis between the digital rays occurred during [[BGDA_Practical_7_-_Week_7#Limb_Development|week 7]].

BGDsmall.jpg

Here are a few simple Quiz questions that relate to Embryo to Fetus transition from the lecture and practical.

1

Which of the following answers describes the human embryonic period:

  the period before replacement of cartilage within the humerus by bone marrow begins
  a discrete entity that has not yet reached 8 weeks of development since the first mitotic division
  the developmental period up to 8 post-ovulatory weeks
  the period when more than 90% of the more than 4,500 named structures of the adult body have appeared
  all of the above are correct

2

In human development, the first trimester is best described as:

  the period when organs begin to function
  the embryonic period and the beginning of the fetal period
  the least critical time of human development
  the beginning of fetal sensory function
  all of the above are correct

3

Which of the following limb development processes has not completed by the end of the first trimester:

  ossification of the limb long bones
  rotation of the upper limb
  rotation of the lower limb
