The term cranium can be ambiguous, in that it can refer to the neurocranium, or the neurocranium and the Facial skeleton It seems MA uses 'neurocranium' as a synonym for chondrocranium. Note there are currently some structures part of both viscero and neurocranium - ethmoid, zyogomatic, ... MA:0000317 Subdivision of skeletal system that surrounds and protects the brain. Includes the skull base, sensory capsules and the central part of the skull roof. TAO:0001580 The cartilaginous parts of the neurocranium undergo endochondral ossification in most species; ossification has been lost in cartilaginous fishes, but the cartilaginous condition of the skull of lampreys is considered to be primitive (Kardong, 1995)[PMID:11523816]. The neurocranium arises from paraxial mesoderm in the head (first five somites and the unsegmented somitomeres rostral to the first somite) and from ectoderm via the neural crest. In Chondrichthyes and other cartilaginous vertebrates this portion of the cranium does not ossify; it is not replaced via endochondral ossification[WP].
