Without it, we wouldn't be able to process information, move our limbs, or even breathe. 435. The majority of head injuries involve falls. The pterion is located approximately two finger widths above the zygomatic arch and a thumb’s width posterior to the upward portion of the zygomatic bone. The corpus callosum is a thick tract of fibrous nerves that serve as a kind of switchboard enabling the brain's hemispheres to communicate with one another. The middle cranial fossa is divided at the midline by the upward bony prominence of the sella turcica, a part of the sphenoid bone. Ask below and we'll reply! Label the Parts of a Sheep Brain. Lateral to either side of this bump is a superior nuchal line (nuchal = “nape” or “posterior neck”). The nasal septum consists of both bone and cartilage components (Figure 15; see also Figure 9). Like any good command center, there is a structure to the brain and its operations that help it carry out its basic functions. It extends from the lesser wings of the sphenoid bone anteriorly, to the petrous ridges (petrous portion of the temporal bones) posteriorly. The walls of each orbit include contributions from seven skull bones (Figure 14). Whereas the cerebral cortex is the cerebrum's outer layer made up of gray matter, and is responsible for thinking, motor function and information processing; the corpus callosum is the cerebrum's inner core, made up of white matter, with four parts of nerve tracts connecting to different parts of the hemispheres. A view of the lateral skull is dominated by the large, rounded brain case above and the upper and lower jaws with their teeth below (Figure 3). Check out 59 medical programs available for high school students. The most posterior is the sphenoid sinus, located in the body of the sphenoid bone, under the sella turcica. The heart pumps blood in and out of the body through the carotid and vertebral arteries. The 5 Strategies You Must Be Using to Improve 160+ SAT Points, How to Get a Perfect 1600, by a Perfect Scorer, Free Complete Official SAT Practice Tests. The ethmoid bone also contains the ethmoid air cells. The anterior lobe and the vermis together are known as the spinocerebellum. The gyri and sulci create the wrinkles we traditionally associate with the brain./ Bruce Blaus/Wikimedia Commons. It is much smaller and out of sight, above the middle concha. Unlike the other two areas, this one gets data directly from a sensory nerve, the vestibular nerve. The cerebellum is responsible for voluntary movements, coordination, balance, posture, muscle tone, and cognitive functions. It joins the frontal bone to the right and left parietal bones. 99 These layers protect the brain from being displaced; separate the cerebrum from the cerebellum; transfer food and waste from the brain to the body; and clean the brain's fluid to keep it running. 3D redering of a human brain. If you want more of a challenge, include anatomical parts, such as the brain stem and cerebellum. These are the medial pterygoid plate and lateral pterygoid plate (pterygoid = “wing-shaped”). The forebrain, midbrain and hindbrain serve as regions that make finding the various parts of the brain easier./ BruceBlaus/Wikimedia Commons. Figure 13. Isolated Mandible. Label the structures of the brain. It consists of three structures: the midbrain, pons and medulla oblongata. It results from a failure of the two halves of the hard palate to completely come together and fuse at the midline, thus leaving a gap between them. The curved, inferior margin of the maxillary bone that forms the upper jaw and contains the upper teeth is the alveolar process of the maxilla (Figure 12). Feb 5, 2020 - Side View Of Brain Labeled .

In the adult, the skull consists of 22 individual bones, 21 of which are immobile and united into a single unit. Each of the paired zygomatic bones forms much of the lateral wall of the orbit and the lateral-inferior margins of the anterior orbital opening (see Figure 2). It is protected by the skull's singular occipital bone. The largest of the conchae is the inferior nasal concha, which is an independent bone of the skull. The inferior nasal concha is an independent bone of the skull. Located inside this portion of the ethmoid bone are several small, air-filled spaces that are part of the paranasal sinus system of the skull.
