{Which of the following best describes the term "ectomesenchyme":
{The bones of the adult skull form only by the process
|type="()"}
|type="()"}
- ectoderm derived from mesoderm
- &nbsp; intramembranous ossification
- epithelium derived from connective tissue
- &nbsp; endochondral ossification
- sensory placodal induction by mesoderm
- &nbsp; neither intramembranous or endochondral ossification
+ connective tissue derived from neural crest
- &nbsp; intramembranous and not endochondral ossification
- none of the above is correct
+ &nbsp; both intramembranous and endochondral ossification
|| The term "ectomesenchyme" refers to {{neural crest}} ('''ecto'''derm) forming connective tissue structures ('''mesenchyme''') in the head.
||Both intramembranous or endochondral ossification form different regions of the skull, the cranial vault and jaw forms by {{intramembranous ossification}} and the cranial base forms by {{endochondral ossification}}. Interestingly the lower jaw, which forms beside Meckel's cartilage of the first pharyngeal arch, forms by {{intramembranous ossification}} of the membrane surrounding the arch cartilage not by {{endochondral ossification}}.
 
- &nbsp; chondroblast cell replacement of osteoblast cells
{Which of the following best describes the buccopharyngeal membrane structure:
|type="()"}
- a ventral surface indentation in the early embryo head
- endoderm layer of the foregut
- ectoderm layer of the epidermis
- ectoderm and endoderm
- none of the above is correct
|| The most common site for an {{ectopic pregnancy}} is the uterine tube (tubal pregnancy).
 


{The secondary palate can be divided into two anatomical parts:
|type="[]"}
- &nbsp; the maxillary components of the first pharyngeal arch
|| Incorrect! This is the primary palate
- &nbsp; the frontonasal prominence
|| Incorrect! This is the primary palate
+ &nbsp; the anterior hard palate
|| Correct! - ossified (contributions from the maxilla and palatine bones).
+ &nbsp; posterior soft palate
|| Correct! - the posterior soft (muscular) palate.
