 Here are a few simple Quiz questions that relate to Week 7 ({{GA}} week 9) from the lecture and practical.
-+++++ Replace template questions below +++++
 <quiz display=shuffle>
-{Which of the following best describes the term "ectomesenchyme":
+{The digits of the upper and lower limbs are separated during development of the hand and foot "paddles" by the process:
 |type="()"}
-- ectoderm derived from mesoderm
+- &nbsp; autophagy, that is a "programmed cell death"
-- epithelium derived from connective tissue
+|| Incorrect!
-- sensory placodal induction by mesoderm
++ &nbsp; apoptosis, that is a "programmed cell death"
-+ connective tissue derived from neural crest
+|| Correct! {{apoptosis}} is the term for "programmed cell death"
-- none of the above is correct
+- &nbsp; cell migration, that separates the developing digits
-|| The term "ectomesenchyme" refers to {{neural crest}} ('''ecto'''derm) forming connective tissue structures ('''mesenchyme''') in the head.
+|| Incorrect! {{cell migration}} is a developmental process, just not involved with digit separation by {{apoptosis}}
+- &nbsp; epithelial mesenchymal transition, that separates the developing digits
+|| Incorrect! {{epithelial mesenchymal transition}} is a developmental process, just not involved with digit separation by {{apoptosis}}
+- &nbsp; mesenchymal epithelial transition, that separates the developing digits
+|| Incorrect! {{mesenchymal epithelial transition}} is a developmental process, just not involved with digit separation by {{apoptosis}}
-{Which of the following best describes the buccopharyngeal membrane structure:
+{Which of the following statements about cleft lip is most correct
 |type="()"}
-- a ventral surface indentation in the early embryo head
++ &nbsp; cleft lip is failure of the maxillary prominences to fuse with the medial nasal prominences
-- endoderm layer of the foregut
+|| Correct! {{Cleft lip}} is failure of the maxillary prominences to fuse with the medial nasal prominences.
-- ectoderm layer of the epidermis
+- &nbsp; cleft lip is failure of the maxillary shelves to fuse with the medial nasal prominences
-+ ectoderm and endoderm
+|| Incorrect! Cleft lip is failure of the maxillary prominences to fuse with the medial nasal prominences. The maxillary shelves fuse during the early fetal period to form the palate.
-- none of the above is correct
+- &nbsp; cleft lip is failure of nasal septum to fuse with the maxillary prominences
-|| The buccopharyngeal membrane ({{oral membrane}}) consists of {{ectoderm}} and {{endoderm}} together. Endoderm layer of the foregut
+|| Incorrect!
- and ectoderm layer of the epidermis are partially correct. The ventral surface indentation in the early embryo head is the stomedeum, on the floor of which is located the {{buccopharyngeal membrane}}.
+- &nbsp; cleft lip occurs during the early fetal period
+|| Incorrect! {{cleft palate}} occurs during the early fetal period.
+- &nbsp; cleft lip occurs due to a single known teratogen
+|| Incorrect! Cleft lip is failure of the maxillary prominences to fuse with the medial nasal prominences. Cleft lip can occur in association with many genetic syndromes and mutations as well as due to known and unknown teratogenic effects.
+{Bone formation by endochondral ossification:
+|type="()"}
+- &nbsp; only occurs in the body
+|| Incorrect!
+- &nbsp; replaces mesoderm with bone
+|| Incorrect!
+- &nbsp; replaces mesenchyme with bone
+|| Incorrect!
++ &nbsp; replaces cartilage with bone
+|| The process of {{endochondral ossification}} replaces a skeletal cartilage template with bone.
+- &nbsp; replaces fibrocartilage with bone
+{One cardiac process occurring during week 7 is:
+|type="()"}
+- &nbsp; atrial septation
+|| Incorrect!
+- &nbsp; atrio-ventricular septation
+|| Incorrect!
+- &nbsp; ventricular septation
+|| Incorrect!
+- &nbsp; heart looping
+|| Incorrect!
++ &nbsp; valve formation
+|| The cardiac process occurring during week 7 is [[Intermediate_-_Heart_Valves|valve formation]] as well as aortic and pulmonary trunk septation.
