It is what you see on the outside of the brain and its actually very thin and wrinkly. The cerebral cortex is actually made up of four lobes as well. The four lobes of it are the frontal lobe, occipital lobe, parietal lobe, and the temporal lobe. We will start by talking about the frontal lobe. The frontal lobe is the lobe directly behind your forehead and it plays a role in thinking, memory, and decisions.
Nomenclature of intervertebral disc is such that it takes the name of the vertebra cephalad to it. The disc between L4 and 5 will be called L4 disc. Dorsal root ganglion (DRG) is present at the level of the intervertebral foramina and it is in the confines of the foramina. Three branches arise distal to the DRG- Ventral ramus, Dorsal ramus and sinuvertebral nerve. The ventral ramus is the most prominent and most important branch and it supplies the structures ventral to the neural canal.
The acetabular cavity consists of the peripheral articular lunate surface and the non-articular acetabular fossa in the center. The articular surface is enlarged by a fibrocartilaginous articular labrum. The lunate surface is crescentic and medially is has the acetabular notch through which the intrascapular ligament of the femoral head emerge and joins the femoral head to the acetabular fossa.
Environmental factors tend to modify the inputs received by the sensory pathway. The developing brain is most vulnerable to these alterations and interacts with the environment to modify its neural circuitry. In addition to other sensory stimuli, auditory stimulation can also act as external stimuli to provide enrichment during the perinatal period. There is evidence that suggests that enriched environment in the form of auditory stimulation can play a substantial role in modulating plasticity during the prenatal period. The molecular mechanisms of various changes in the hippocampus following sound stimulation to effect neurogenesis, learning and memory are described.
Hind brain (Rhombincephalan) the hind brain contain the brain stem and the medulla oblongata (Myelencephalon) form by the anterior thickening of basal plate and posterior alar plate separated by sulcus in the fourth ventricle. The hind brain continues to form the spinal cord. As like cerebrum, cerebellum has fissured mass in the posterior cranial fossa attached with brain stem by three pairs of peduncles. From the base of the brain stem the 12 pairs of cranial nerves are arising. The motor nuclei of the IX, X, XI and XII cranial nerves line in the fourth ventricle is formed by the basal plate neurons.
We 're going to talk about these five parts, which are key players on the brain team: cerebrum (say: suh-REE-brum) cerebellum (say: sair-uh-BELL-um) brain stem pituitary (say: puh-TOO-uh-ter-ee) gland hypothalamus (say: hy-po-THAL-uh-mus) The Biggest Part: the Cerebrum Brain CerebrumThe biggest part of the brain is the cerebrum. The cerebrum makes up 85% of the brain 's weight, and it 's easy to see why. The cerebrum is the thinking part of the brain and it controls your voluntary muscles — the ones that move when you want them to. So you can 't
INTRODUCTION Anatomy and Physiology of Angiocentic Glioma The most complex part of the body is the brain. It controls muscles movement, behavior, senses and all other functions of the body. The gray matter or cerebral cortex in the brain is the place where all the information is processed. Meanwhile, the cerebral lobe is the main source of intellectual activities. The nerve fibers in the two hemisphere of the cerebral lobe cross over and causing the right side of the cerebrum to control left side of the body and left side of the cerebrum to control right side of the body.
The frontal sinus is therefor able to communicate with, and drain its contents into the ostiomeatal complex because of the connection between its frontonasal duct (recess) and the ethmoidal infundibulum. The uncinate process, which forms the anterior and medial limitation of the hiatus semilunaris and the ethmoidal infundibulum (respectively), is a thin, crescent shaped, bony leaflet that emerges from the ethmoidal labrynth
This is related to the damage of the motor cortex which is located in the frontal lobes. The motor cortex is a band of neurons located at the back of each lobe in the brain. The neurons are responsible for the movements of voluntary muscles. It communicates to the body by sending out signals to the nervous system, specifically the peripheral. Phineas Gage's case study was important because it provided great detail of the brain, specifically about the frontal lobes, and how they work.
