In the white matter area of the medulla oblongata contains ascending and descending nerve tracks which cross the brain and spinal cord. The protrusions in the white matter forms the pyramids with corticospinal nerve connect the cerebrum with spinal cord which controls the movement of voluntary muscles. These nerve tracks cross the left side to the right side of the body. The medulla regulates the force and heart rate through the cardiovascular system and medullary rhythmic area of respiratory center controls the respiratory processes. Other functions are controlling reflexes for vomiting, swallowing, sneezing and coughing and hiccupping.
To better understand Biopsychology, one has to learn about the three most crucial parts, which are the brain, neurotransmitters, and the nervous system. The brain is in-charge for the cognition, senses, motor abilities, and feelings through its’ four lobes of the
Their journey is comprised of being transmitted through the spinal cord, past the medulla where they cross, through the thalamus, and finally to the parietal lobes, specifically the postcentral gyrus. Here, in the postcentral gyrus, the somatosensory cortex is located. Divided into primary and secondary, the somatosensory cortex houses neuron designated to specific locations of the body that they are responsible for detecting sensations
(Illegal drugs) Firstly, in the United States there are many different drugs such as cocaine, heroin, crack, ice, and marijuana, which are all illegal. Secondly, there are also some prescription drugs are also illegal and they are Prescription Depressant Medications, Prescription Stimulant Medications (Amphetamines) and Prescription Pain Medications (Opioids). On the other hand, however, the question that why these drugs are illegal also attracts many people’s attention a lot. Firstly, they are illegal as they are addictive, mind-devastating and sometimes can be lethal. They are found to be harmful both physically and mentally.
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.
Syn : means together. 2. haptein : to clasp . means to keep holding something together . (4) CHEMICAL SYNAPSE: DEFINITION: Chemical synapses are defined as : Biological junctions through which neurons signals can be exchanged To each other and to non neuronal cells such as in the muscles and The glands and they allow the neurons to form circuit in central nervous System. They are thus very important biological computations that underlie perceptions and thoughts.
In the context of addiction, one would be considered under these terms when over using drugs and alcohol, not just occasionally using them or being prescribed something. Addiction is a self inflicted disease which occurs when one initially decides to make the decision to immediate them. As a result of the usually voluntary act, the repetition of abusing the substance results in brain challenges. This is the basis of why these addictions are called diseases. The brain accumulates the need for the substance, eventually becoming not only a mental need but sometimes a physical need.
There are countless risks when it comes to the usage of these drugs. People can experience shortness of breath, dizziness, disorientation, sudden personality changes, and many others. They can turn a healthy individual into someone unrecognizable and self-destructing. The people that become addicted to these heavy drugs will often lose ties to family and only work towards getting the drugs, they can lose hope and start to feel worthless. There is no reason to let these drugs become legal.
It partakes in directing the volume and organization of liquid encompassing the cerebrum through particular transport procedures, and hence adds to homoeostasis of the focal sensory system (Peterson, 2012). The blood-brain barrier is a mechanism that controls the passage of substances from the blood into the brain. It lets essential metabolites, such as oxygen and glucose, pass from the blood to the brain and central nervous system. It is a cellular and metabolic barrier located at the capillaries in the brain that alters permeability, restricting the passage of some chemical substances from the bloodstream into the neural tissue, while allowing other substances to pass into the
