BGDsmall.jpg Here are a few simple Quiz questions that relate to Abnormalities in development from the lecture and practical.

{Cleft palate (palatoschisis) in humans occurs differently between the sexes and occurs more frequently in: |type="()"} +   females -   males || Cleft palate (palatoschisis) in humans has occurs in females (57%) more than in males (43%).

{The abnormality of a pharyngeal fistula refers to a: |type="()"} -   a cartilaginous developmental remnants -   a bony developmental remnants -   a cervical sinus defect +   a pharyngeal membrane defect -   a pharyngeal groove defect || 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.

{According to the "Ten most frequently reported Birth Anomalies" which form of clefting occurs more frequently? |type="()"} +   Cleft Palate -   Cleft Lip and Palate || "Ten most frequently reported Birth Anomalies" (2003-2004) Cleft Palate was number 7and Cleft Lip and Palate was number 10 on the list, cleft lip also occurred with another defect in 33.7% of cases.

{There are a number of skull abnormalities due to premature suture fusion. Which of the following clinical terms refers to premature cranial suture fusion: |type="()"} -   oxycephaly -   plagiocephaly -   caphocephaly -   trigoncephaly +   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? |type="()"} -   maternal rubella infection -   maternal goiter -   erythroblastosis -   maternal diabetes +   any of the above ||Any of the above conditions (maternal rubella infection, maternal goiter, erythroblastosis, maternal diabetes) could cause congenital deafness.

{Rubella infection during pregnancy may cause; |type="()"} -   congenital deafness -   congenital glaucoma -   cochlear duct damage -  corneal clouding +   any of the above ||Any of the above conditions can result from rubella infection during pregnancy. \
