Splanchnocranium

The splanchnocranium, or splanchnocranium, is the part of the skull that develops from the second gill arches. This part of the skull is an important part of the skull as it is involved in the formation of the lower jaw.

The splanchnocranium is located on the underside of the skull, under the lower jaw. It consists of two parts: upper and lower. The upper part of the splanchnocranium is called the vomer, and the lower part is the mandibular bone.

The vomer is part of the upper jaw and is involved in the formation of the upper part of the face. The mandibular bone is part of the lower jaw and is responsible for its development.

The development of splanchnocranium begins in the embryonic period and continues after birth. During this process, the vomer and mandibular bones develop from the second branchial arches, which are found on the neck.

As the vomer and mandibular bones begin to develop, they join together to form the lower jaw. The mandible is an integral part of the face and is involved in chewing, swallowing and speech.

In general, the splanchnocranium is an important element of the skull, which is involved in the formation of the lower jaw and face. It develops from the second branchial arches and is associated with other parts of the skull such as the temporal bones and the occipital bone.

The splanchnocranium is the part of the skull that develops from the second gill arches and represents the lower part of the jaw. It is an important component of the skull and plays an important role in the formation of the face and jaw system.

The splanchnocranium consists of several elements, including the mandible, the hyoid bone, the lower part of the occipital bone, and the lower part of the sphenoid bone. The lower jaw consists of two parts - the body and the ramus, which are connected together by a joint. The hyoid bone is part of the lower jaw and connects it to the hyoid bone. The lower part of the occipital bone forms the bottom of the jaw fossa and is the basis for the development of the lower jaw. The lower part of the sphenoid bone is the front part of the skull and forms its lower wall.

The development of splanchnocranium begins at 12-14 weeks of intrauterine development and continues until birth. After birth, the splanchnocranium continues to develop and forms into the lower jaw, which is the main organ of the maxillofacial region.

The upper jaw develops from the first branchial arch, and the lower jaw develops from the second branchial arch. The mandible is one of the most important structures of the body, as it enables speech, chewing, swallowing and breathing.

Thus, the splanchnocranium is an important part of the skull, the development of which begins in the early stages of development and forms the lower jaw.

Splanchnocranchium (splanchnocraniiu'm) is a part of the skull (Fig. 139), which is the postmental section of the metasesal 2nd cervical vertebra, developed from one of the lower gill bones of fish. On the diaphyra there are also processes of the splanchocranium, which differ from the unpaired upper branchial sections in a different orientation of the internal row of structures.
