(The nervous system Louisa Idzal) The nervous system is all connected because it’s a web of nerve cells and fibers that all send nerve impulses throughout and between body parts. The nervous system is really important because it’s in charge of sending messages to the spinal cord and brain to and from all parts of the body. Main organs of the nervous system are Nervous Tissue, Brain, Spinal Cord, Nerves, Sense Organs, and the Cerebrospinal Fluid. The nervous tissue is the main tissue of the…

3. A. Cranial nerve involvement can be broken down into two portions. The anterior 2/3 of the tongue are innervated by the Chorda Tympani branch of the Facial nerve which is carried by the lingual nerve which branches off the mandibular branch of the Trigeminal nerve. Sensory component of the anterior 2/3 is maintained by the lingual nerve. The posterior 1/3 of the tongue is innervated by the glossopharyngeal nerve which supplies both sensory and taste. B. The human tongue contains multiple…

The study of psychology involves studying the mind and behaviour of people. Researchers test individuals based on questions they have about why people behave and think the way the do. Part of this, is how the brain works together to perform these day-to-day actions. However, there are many situations that challenge the performance of actions. A common challenge that occurs in middle ages people is the Alzheimer’s Disease. The Alzheimer 's Disease is a serious condition that affects the loss of…

The brain is an organ that serves as the center of the nervous system for most living things. There are only a few animals that do not have a brain like starfish or jellyfish. The brain is located in the head. It receives messages from other organs. The brain is the most complex organ. In a human, the cerebral cortex has more than a billion neurons. Each of these neurons are connected by synapses. These synapses are connected to several thousand other neurons. Neurons communicate with one…

Question #1. The brain has two hemisphere, the right and left side. Each hemisphere has it own function working different ways, but are connected by the corpus callosum to serve the body. The left hemisphere controls the right side of the body. The left side is more of the academic side and logical side. The left side is better at understanding language. Language as in being able to communicate with others (speaking). Also comprehending and reading. Left side is better at musical tempo like…

Virchow-Robin (VR) spaces or perivascular spaces of the brain refer to spaces that accompany the cerebral vessels as they pass from subarachnoid space into the brain parenchyma. A few evident perivascular spaces can be considered normal at any age but many visible perivascular spaces are not. The relevance of visible perivascular spaces to SVD is shown by their presence in increased numbers in patients with white matter hyper-intensities and with symptomatic lacunar ischemic stroke. The…

Introduction The statistics regarding the increase in ADHD rates in the United States over the past years are alarming. This issue is of great concern to not only adolescents but parents.

Our sensorimotor has many parts to function and manipulate what we want our body part to do. We simply must think and react to what are next move and in rapid millisecond either our hand or leg moves. As this occurs, our primary somatosensory cortex that’s located in our central sulcus has a full chart of information lined up for our function to travel all the way to our spinal cord and make a movement. As Agnosia damages the path of any function of either of the temporal lobe or cerebellum, it…

6) The monoamine theory of depression foresees the underlying pathophysiologic source for depression is the diminution of levels of norepinephrine, serotonin, and dopamine within the central nervous system (National Center for Biotechnology Information). Indication for this hypothesis is sustained with clinical trials and animal testing. Barchas, J., and Altemus, M.
