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
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.
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.
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. Usage will only increase and the treatment will become more difficult because the drug will be so readily available. It is an unnecessary cycle that can be
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
Furthermore, minors could get their hands on marijuana, leading to it disrupting their brain growth. Finally, marijuana would increase safety issues for the state, because it affects the way people 's CNS(central nervous systems) works. One of the reasons marijuana should not be legalized is because it is a gateway drug. NYLN(2015) says that
The hypothalamus communicates to each lobe differently. The hypothalamo-hypophyseal tract system is the specific way the hypothalamus communicates with the posterior lobe of the pituitary gland. It is a nervous system connection with direct connecting neurons. The neurons are located in the hypothalamus and then axons extend down to the posterior lobe of the pituitary gland. The neurons produce hormones that slide down the axons and end up in the posterior lobe.
9. Describe the areas and major functions of the primary motor cortex. The primary motor cortex, or M1, is one of the principal brain areas involved in motor function. M1 is located in the frontal lobe of the brain, along a bump called the precentral gyrus.
The medulla oblongata is located between the pons and spinal cord. This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure. The midbrain is involved in functions such as vision, hearing, eye movement, and body movement. The pons are involved in motor control and sensory analysis. For example, information from the ear first enters the brain in the pons.
The nervous system has many significant functions such as direction of your movements, focusing of the eyes, pain sensory, contraction of the muscles allowing your heart to pump sending blood and oxygen to all your vital organs and removing harmful toxins. Your brain is the control centre of the body. The most largest and complex part of the brain is the cerebrum, the centre of learning. This controls the way you use language, feel emotions and think. It is divided into two sides which are connected together by nerve bundles called the corpus callosum.
