Cerebellum

My group did our dissections on the Frog, they belong to the Chordate phylum because of its endoskeleton, and their nerve cord that runs along the spinal cord and connects to their brains. This means that they have a central and peripheral nervous system. Back to their brains, they’re divided into three parts, the fore-brain, mid-brain and hind-brain. The fore-brain controls the frogs sense of smell (the Olfactory lobe), along with the cerebral hemispheres, and diencephalon. The mid-brain…

called the cerebrum. The cerebrum is divided into two cerebral hemispheres, which develop from the forebrain. The hemispheres have the cerebral cortex which contains ten billion nerve cells. Underneath is the brainstem, and behind that is where the cerebellum is. The outermost layer of the cerebrum is the cerebral cortex is divided…

sense to the brain. Motor neurons control the contraction and extension of muscles, and interneurons are neurons that communicate with and relay messages between neurons. The central nervous is made up the brain, which is made up the cerebrum, the cerebellum, and the brain stem which then can be divided into the medulla oblongata, the pons, and the midbrain. The cerebrum is responsible for conscious thought, learning, and thought. Also, this part of the brain can be divided into two hemispheres,…

While many teens think they can have just a few alcoholic beverages with no consequences, it is a proven fact that teens should not be drinking underage. 18 year olds and younger are not able to handle the responsibility of drinking alcohol and the risk factors that are associated with it. As a result, many teens can end up in life-threatening situations that could alter their lives forever. The drinking age should not be lowered to 18 because brain growth of teens that age are underdeveloped…

brain activity between the different conditions. They also measure the immediate early genes such as the egr-1 and c-fos in four brain regions: dorsomedial telencephalon (amygdala), dorsolateral telencephalon (hippocampus), pre-optic area and, the cerebellum. These four brain regions are known to have control in fear responses. In the experiments, they had size-matched males placed in a tank that was subdivided into two compartments in…

the brainstem and into the thalamus. It acts as a filter for some of the sensory messages, relaying important information to other brain areas, and controlling arousal. Then comes the cerebellum, also called the “Little brain”. It coordinates voluntary but unconscious movements like walking and speaking. The cerebellum helps judge time, discriminate sounds and textures, and control emotions. It also helps process and store memories for things that cannot be consciously recalled such as driving a…

and body organs. The part of the brain that are heavily damaged that is associated with drinking alcohol are the cerebral cortex that is responsible for our decision making and problem solving. Another areas of the brain that can be damaged is the cerebellum, which is responsible for the movement coordination, and then hippocampus, which is responsible for the learning and memorization. Besides the brain being damaged, major organs can be at risks as well that can cause major health issues from…

Were the human body compared to a machine by today’s standards, it would be considered something of a marvel that is far ahead of its time. In addition to bringing together multiple systems to work as one cohesive unit, it also has the ability to independently maintain relative amounts of consistency and constancy within and between these systems. Comparatively speaking, if a computer is infected by a virus the user typically has to manually diagnose and remove the virus, but if a person is…

should also need to look for serum immunoglobulin levels (IgE, IgA, IgG/IgM), and B/T cell levels of the patient. Low levels of these components indicate defects in humoral and cellular immunity. Other tests such as radiosensitivity assay, MRI of cerebellum, chest x-ray can be obtained if necessary (3). Prevalence and…

complicated motor functions, such as required changes in output forces or velocities, or motor response to visual or auditory input. Also, the basal ganglia and thalamus are important coordinating centers for goal­directed motor programs and patterns. The cerebellum allows for unimpeded movements of those motor programs. Motor programs are continuously adjusted throughout an action, made possible by constant afferent input about the movement taking place. Inputs to motor neurons may lead to…
