The skull is a bone protective cavity for the brain. [1] The skull is composed of three types of bone: cranial bones, facial bones, and ear ossicles. Two parts are more prominent: the cranium (pl.: craniums or crania) and the mandible. [2] In humans, these two parts are the neurocranium (braincase) and the viscerocranium (facial skeleton) that ...
Orange: Temporal bone (2) Green: Occipital bone (1) Red: Ethmoid bone (1) In human anatomy, the neurocranium, also known as the braincase, brainpan, or brain-pan, [ 1 ][ 2 ] is the upper and back part of the skull, which forms a protective case around the brain. [ 3 ] In the human skull, the neurocranium includes the calvaria or skullcap.
Researchers unearthed the skull of a previously unknown starling-sized bird species named Navaornis hestiae that was so well preserved they were able to digitally reconstruct its brain and inner ...
Cranial cavity. The cranial cavity, also known as intracranial space, is the space within the skull that accommodates the brain. The skull minus the mandible is called the cranium. The cavity is formed by eight cranial bones known as the neurocranium that in humans includes the skull cap and forms the protective case around the brain. The ...
The facial skeleton comprises the facial bones that may attach to build a portion of the skull. [ 1 ] The remainder of the skull is the neurocranium. In human anatomy and development, the facial skeleton is sometimes called the membranous viscerocranium, which comprises the mandible and dermatocranial elements that are not part of the braincase.
The brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system.
The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into: the cranium (8 bones: frontal, 2-parietal, occipital, 2-temporal, sphenoid, ethmoid), and. the facial bones (14 bones: 2-zygomatic, 2 ...
Cranial kinesis is the term for significant movement of skull bones relative to each other in addition to movement at the joint between the upper and lower jaws. It is usually taken to mean relative movement between the upper jaw and the braincase. [1] Most vertebrates have some form of a kinetic skull. [1]
