{Which of the following best describes the term "ectomesenchyme":
{Cleft palate (palatoschisis) in humans occurs differently between the sexes and occurs more frequently in:
|type="()"}
|type="()"}
- ectoderm derived from mesoderm
+ &nbsp; females
- epithelium derived from connective tissue
|| Cleft palate (palatoschisis) in humans has occurs in females (57%) more than in males (43%).
- sensory placodal induction by mesoderm
- &nbsp; males
+ connective tissue derived from neural crest
- none of the above is correct
|| The term "ectomesenchyme" refers to {{neural crest}} ('''ecto'''derm) forming connective tissue structures ('''mesenchyme''') in the head.


{Which of the following best describes the buccopharyngeal membrane structure:
{The abnormality of a pharyngeal fistula refers to a:
|type="()"}
|type="()"}
- a ventral surface indentation in the early embryo head
- &nbsp; a cartilaginous developmental remnants
- endoderm layer of the foregut
- &nbsp; a bony developmental remnants
- ectoderm layer of the epidermis
- &nbsp; a cervical sinus defect
- ectoderm and endoderm
+ &nbsp; a pharyngeal membrane defect
- none of the above is correct
|| A pharyngeal fistula refers to a pharyngeal membrane defect, a tract extends from pharynx (tonsillar fossa) beween the carotid arteries (internal and external) to open on side of neck.
|| The most common site for an {{ectopic pregnancy}} is the uterine tube (tubal pregnancy).
- &nbsp; a pharyngeal groove defect

+ &nbsp; Cleft Palate
|| "[[Template:10Victorian Anomalies03-04|Ten most frequently reported Birth Anomalies]]" (2003-2004) Cleft Palate was number '''7'''and Cleft Lip and Palate was number '''10''' on the list, cleft lip also occurred with another defect in 33.7% of cases.
- &nbsp; Cleft Lip and Palate
{There are a number of skull abnormalities due to premature suture fusion. Which of the following clinical terms refers to premature cranial suture fusion:

- &nbsp; plagiocephaly
- &nbsp; caphocephaly
- &nbsp; trigoncephaly
+ &nbsp; craniosynostosis
|| Craniosynostosis is the premature cranial suture fusion, results in an abnormal skull shape, blindness and mental retardation. Oxycephaly (tower skull) results from premature coronal suture synostosis. Plagiocephaly results from asymmetric coronal suture synostosis, incidence is approximately 1 in 300 live births. Caphocephaly results from premature sagittal suture synostosis. Trigoncephaly (wedge skull) results from metopic suture synostosis.
{Which of the following would cause congenital deafness?

||Any of the above conditions (maternal {{rubella}} infection, maternal goiter, erythroblastosis, {{maternal diabetes}}) could cause congenital deafness.

- &nbsp; congenital deafness
- &nbsp; congenital glaucoma
- &nbsp; cochlear duct damage
- &nbsp;corneal clouding

||Any of the above conditions can result from {{rubella}} infection during pregnancy.
{Malformations of auricles may be associated with:
