What is neurocranium and viscerocranium?
The neurocranium is a protective shell surrounding the brain and brain stem. The viscerocranium (or facial skeleton) is formed by the bones supporting the face.
What is the viscerocranium?
The viscerocranium is a collection of bones that make up the face skeleton. It is named in contrast to the neurocranium (braincase), or the bones of the skull that accommodate the human brain.
What is neurocranium and Dermatocranium?
The neurocranium/chondrocranium includes the box that encloses the brain and the capsules surrounding the sense organs. It protects the brain. 2. The splanchnocranium is the visceral portion of the skull that supports the gills and contributes to the jaws. 3.The dermatocranium is the dermal bone that is believed to.
What are the 8 bones of neurocranium?
In humans, the neurocranium is usually considered to include the following eight bones:
- 1 ethmoid bone.
- 1 frontal bone.
- 1 occipital bone.
- 2 parietal bones.
- 1 sphenoid bone.
- 2 temporal bones.
How many bones are in viscerocranium?
Viscerocranium Bone Complex The viscerocranium includes six paired (zygomatic, maxillae, palatine, lacrimal bones and the inferior nasal conchae) and two unpaired bones (vomer & mandible). Viscerocranium, or facial skeleton bones ex situ & in situ.
Are there 22 or 28 bones in the skull?
The human skull is generally considered to consist of twenty-two bones—eight cranial bones and fourteen facial skeleton bones. In the neurocranium these are the occipital bone, two temporal bones, two parietal bones, the sphenoid, ethmoid and frontal bones.
What is a braincase?
Medical Definition of braincase : the part of the skull that encloses the brain — see cranium.
What differentiates chondrocranium splanchnocranium and dermatocranium from each other?
The chondrocranium, a cartilaginous neurocranium, protects the brain, otic, and nasal organs. The splanchnocranium is present as a continuous visceral skeleton, has a pharyngeal basket, and is branchial in function. The dermatocranium is present as a dermal head skeleton and varies depending on group.
Why is it called the neurocranium?
In human anatomy, the neurocranium, also known as the braincase, brainpan, or brain-pan is the upper and back part of the skull, which forms a protective case around the brain. In the human skull, the neurocranium includes the calvaria or skullcap….

How many bones are in the viscerocranium?
The viscerocranium or facial bones supports the soft tissue of the face. The viscerocranium consists of 14 individual bones that fuse together. However, the hyoid bone, ethmoid bone, and sphenoid bones are sometimes included in the viscerocranium.
What is the meaning of viscerocranium?
vis·cer·o·cra·ni·um. That part of the cranium derived from the embryonic pharyngeal arches; comprises the facial bones of the facial skeleton (under bone) and is distinct from that part of the cranium that forms the neurocranium (braincase). viscerocranium. the facial skeleton.
What are the three parts of the viscerocranium?
Elements of the viscerocranium were described following Hunt Von Herbing et al. The measurements were organized into three regions of the head: the anterior skull, or the viscerocranium, including the teeth; the midskull, near the orbits; and the posterior skull.
Is viscerocranium related to neurocranium commitment in rats subjected to nutritional manipulation?
Key words: Elasmobranchii; Rhinoptera; Viscerocranium. The authors found a higher commitment of viscerocranium in relation to neurocranium in rats subjected to nutritional manipulation.
What are the functional demands of viscerocranium?
Studies about viscerocranium must consider the functional demands (Miller & German) for example the demands related to the use of chewing musculature, that is important not only to guide the craniofacial growth but also to define new variable and parameters referred to feeding and possibly to nutrition.
