can develop is the loss of gastric parietal cells, which are responsible for the secretion of intrinsic factor, a protein necessary for absorption of vitamin B12 in the ileum. Vitamin B12 helps the body make healthy red blood cells and helps keep nerve cells healthy. It is found in animal foods, including meat, fish, eggs, milk, and other dairy products. Diseases, conditions, and lifestyle are factors that can influence the development of pernicious anemia. Pernicious anemia is more common in…

Every year about 42.5 million American adults suffer from a mental illness. Also 1 in every 10 children suffer from mental illness(¨The Rise¨). Mental illness affects younger generations more frequently than middle aged generations. Half of all chronic mental illness begin by the age of 14(¨Mental Health¨). Additionally, the rates of depression and anxiety among young people in America have been increasing steadily for the past 50 to 70 years. ¨When I first started working in depression 30 years…

The exact cause of the obliteration of the processusvaginalis is still unknown, but some studies reported that calcitonin gene-related peptide (CGRP), released from the genitofemoral nerve, may have a role in the fusion( Al Shareef , 2007). The prevalence of PPV is highest during infancy and declines with age(Osifo, 2008). The processus vaginalis typically obliterates around the 36th and 40th week of gestation. It is thought…

Overview A pituitary adenoma is a benign growth that occurs in the pituitary gland. Sometimes when the pituitary gland becomes covered with tumor-like growths it begins to secrete an excess of hormones. Though mostly benign, these tumors can still cause problems throughout the body. Definition & Facts The pituitary gland is located below the brain and above the nasal passages. This gland belongs to a system known as the endocrine system that includes the pancreatic gland, adrenal gland,…

system that regulates impulses, chemicals, and commands to the body through the Central Nervous System (CNS) or the Peripheral Nervous System (PNS). The CNS is composed of the brain, brainstem, and spinal cord while the PNS is composed of cranial and spinal nerves. The brain’s smallest unit of cells are called…

Five distinct clinicopathological entities have been described: intracranial lesion (solitary or multiple), diffuse leptomeningeal or periventricular lesions, vitreous/uveal deposits, intradural spinal cord lesion, and nerve seeking lymphoma (Neurolymphomatosis) (Batchelor, & Loeffler, 2015). Medical treatment: Aside from high-dose systemic methotrexate (MTX), there is little agreement on the best components of therapy for newly diagnosed PCNSL, and there is variation…

A person has about 5,000 taste buds or more, and each of these taste buds have 100 sensory cells that are most commonly stimulated by sugar, salt, and other acid. These sensory cells are the ones sending impulses to the cranial nerves, which can be found in the brainstem. It would then send the message to the thalamus going to the cerebral cortex that tells us what we just tasted. It may be a long process but it is obviously fast especially if we have tasted the food before…

function deficits. He has mild to moderate decreased executive cognitive ability. He has a mildly masked appearance of his face at rest. His face continues to symmetric at rest with good strength throughout his face. The remaining of his cranial nerve examination was within normal limits. He has good strength of his extremities. He has mild cogwheel rigidity of both wrists and minimal cogwheel rigidity of both elbows. He has minimally increased tone of his lower extremities, not true…

lectures became the highlight of the year, and made me really keen to learn more about the subject. I particularly enjoyed reading about complex somatosensory pathways, neurotransmission in the nervous system and the importance of the different cranial nerves. By the end of the summer, I had come to the decision that I wanted to pursue a career in neuroscience and research. I have always had a keen interest in biochemistry and genetics. I have a sister with Autism, which encouraged my curiosity…

Task One Explain the functions of the following The Temporal Lobe The temporal lobe is placed in the base of the cortex behind the temples. It is one of the four exceeding lobes in the cerebral cortex. The temporal lobe develops sensory information. It controls select listening and the data collected from the ears. Sound and speech is also created here. The temporal lobe conceives significant speech, including sounds and pitches. Long term and visual memories are stored here. The temporal…
