The cerebellum is located behind the pons and the upper part of the brain stem, and it sits right below the main part of the brain. The cerebellum is nicknamed the “little brain” for its appearance. It has similarities in appearance with the brain, only smaller in stature; hence the nickname. The cerebellum is divided into two hemispheres, or two halves. “It is a relatively small portion of
The amygdala is known for its ability to regulate emotion and influence on stress hormones for memory (lumen). For example if someone has arachnophobia and sees a big spider the stress hormones caused by the appearance of spiders causes you to remember that exact moment. Whenever there is a moment where a person is stressed, it tends to be retained within long and short-term memories because of its severity on the brain. The hippocampus is involved in memory because it is used to recall information and also transfers new information into long-term memory (lumen). Not only does the hippocampus recalls information; but, also gives memories meaning and connect them to other means through the cortical regions of the brain (lumen). The cerebellum controls things like procedural memory, motor learning, and classical conditioning. Things that are day to day movements such as blinking your eye is controlled by your cerebellum; you perform the movement without realizing it, because you are used to it (lumen). The brain is a very complex organ that is being utilized all-day and even while you are asleep and processing important
The cerebrum is the largest part of the brain and is located at the front and top of the head. There are four parts of the cerebrum; the inferior frontal gyrus, the dorsolateral frontal cortex, the frontal gyrus, and the motor cortex. Each of the four parts, in their own way, help recall the memory of the song and it’s lyrics.
The first part of the brain that I had chosen that helps carry out the activity I had chosen was the cerebellum. The cerebellum plays a major part in being able to accomplish taking a shower. The cerebellum makes taking a shower possible because this part of the brain maintains your balance and muscle coordination. For example, if you were taking a shower you would need to keep your balance while washing yourself. But you would also need to be able to bend over to grab your shampoo and wash your hair.
After many studies scientist have found that humans might be one of the most unique species in the world. There are multiple reasons why we are unique, and their are multiple reasons why they made us our own species, and own category. We are considered Homo sapiens or humans. Humans can feel emotions because of how our brain functions, the experiences we just went through,and the choices we made to get to the experience, and that’s why we are considered humans.
The brain is a complex organ made of several parts, each with a specific function. The cerebellum is the part of the brain that is involved in motor control such as maintaining physical balance, thereby allowing a person to be in control of his/her body movements. It also coordinates voluntary muscle movements like walking by controlling the timing at which different muscles work together to produce accurate movement in a particular body part. Because of its involvement in motor control, damage to the cerebellum will result in difficulty in moving body parts and keeping maintaining physical balance. Muscles will not work properly together and a person 's movement will be exaggerated. The hypothalamus is another part of the brain that is situated below the thalamus. This small structure, which is often referred to as the thermostat of the body helps regulate body temperature, amount of fluid in the
The principal arteries of supply to the head and neck are the “two common carotids; they ascend in the neck and each divides into two branches. One is the external carotid, supplying the exterior of the head, the face, and the greater part of the neck and two the internal carotid, supplying to a great extent the parts within the cranial and orbital cavities” (Common). Coronary Arteries are the network of arteries that encircles the heart to provide its blood supply. The two primary coronary arteries, the right coronary artery and the left coronary artery, branch from the aorta as it arises from the left ventricle. The left coronary artery is significantly larger and supplies the left heart. The left subclavian artery branches directly from the aorta, the largest artery in the body. The aorta curves above the heart before running down the front of the backbone. “The brachiocephalic artery, also known as the brachiocephalic trunk or innominate artery, is much shorter than the aortic arch and splits into two to form the right subclavian artery and the right common carotid
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.
discovered an unusual extra lobe sat adjacent to the Limbic system. They were uncertain as to
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
Furthermore, the regulation of the respiratory center can be modified in response to inputs from other brain regions, receptors in the peripheral nervous system, and other factors (chemoreceptors, voluntary control, etc.) in order to preserve the homeostasis of breathing. The respiratory center comprises of dispersed clusters of neurons located near the brain stem that modify the breathing muscles of the thorax by transmitting nerve impulses from centers in the brain which signals either contraction or relaxation (absence of nerve impulses). The respiratory center can be divided into two sections: the medullary respiratory center in the medulla oblongata and the pontine respiratory group (or pneumotaxic area) in the pons. The medullary respiratory
overridden by the cortex. We can gather that the most complex behaviors in highly developed species such as mankind itself are associated with the cortex. The cerebral cortex is made up of tightly packed neurons and is the wrinkly outermost layers that surrounds the brain. The cortex is divided into four different lobes, the frontal, parietal, temporal, and occipital. It is responsible for higher thought processes including speech, and decision making which respectively is the equivalent to
The small saphenous vein (SSV) is a superficial vein in the leg. It originates from the lateral side of the dorsal venous arch passes behind the distal end of the fibula and up the back of the leg to penetrate deep fascia and join the popliteal vein posterior to the knee . This vein is considered the second largest blood vessel in the leg. Like most of the superficial leg veins, this vein features smooth muscle cells in its adventitia and the inner media . Also SSV is in danger of becoming distended or having thrombosis . On the other hand, internal thoracic artery (ITA) arises as a major branch of the subclavian artery in the neck, it passes posterior to the clavicle and the large veins in the region and anterior to the pleural cavity.
Many psychologists, professors and other researchers have studied the mechanism and explanation of having a left-handed trait among a few individuals. The brain hemisphere division of labor is the most accepted theory about the left-handedness of a person. (Broca, 1960) proposed that the handedness of a person can be associated by the brain hemisphere division of labor.
The hippocampus anatomically is located in the temporal lobe of the human brain on the medial surface deep inside the uncus. It is a major component of the limbic system. Its name is derived from a Greek word which means “Sea horse”. The curved shape of the hippocampus resembles a ram’s horn and hence Cornu Ammonis (CA). The medial part below the CA forms the dentate gyrus. The hippocampus is differentiated from other cortical areas in the brain due to its archicortical architecture and highly laminar organization. The Cornu Ammonis is subdivided into CA1, CA2 and CA3 region with CA3 proximal to the dentate gyrus. Sometimes the polymorphic layer of the dentate gyrus is regarded as the CA4 region.
