A Glial Cell is a non-neuronal cell that maintains homeostasis from myelin and it also provides support and it provides protection from neurons in the central nervous system. Glial cells also provide support and protection for neurons in the peripheral nervous system. Glial cells are known as being in large quantities in the central nervous system. Glial cells are very different form nerve cells. They differ in the way that they do not participate in synaptic interactions and electrical…

Important Pathways to recognize prior to understanding clinical complications and scenarios: Lingual Nerve Pathway: CNV3 → Lingual Nerve (+Chorda Tympani from Facial Nerve) →Submandibular Ganglion Inferior Alveolar Nerve Pathway: CNV3 Mandibular Nerve → Inferior Alveolar Nerve →Inferior Dental Nerves → Mental Nerve (+ Nerve to Mylohyoid) Lingual Artery Pathway: External Carotid Artery→ Lingual Artery → Sublingual Artery, Deep Lingual Artery, Dorsal Lingual Artery Inferior Alveolar Artery…

(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…

What does the term neroglia mean? What are the 4 types of neuroglia cells in the CNS? Discuss this in detail. Neuroglia is a group of cells, in the nervous tissue that supports neurons that keeps the nervous system functioning and together. The 4 types of neuroglis cells of the CNS: (1.) Astrocytes are cells that support and structure cells that is a barrier for the brain through blood. (2.) Microglial cells are cells that remove dirt and attack microbes. (3.) Ependymal cells are cells that…

Marfan syndrome (MFS) is a genetic disorder which affects the connective tissue of the body. MFS is autosomal dominant, with “approximately seventy five percent of people” diagnosed with MFS having a parent that has the disorder. The other “twenty five percent” of people with MFS have developed this disease through new gene mutation (NIH. National Human Genome Research Institute). This disease is not specific to gender, race or region, and is potentially life threatening. MFS affects multiple…

How one acts, thinks, or feels all come from the body’s nervous system. The nervous system is the body’s communication center that transmits thoughts and actions from the brain and spinal cord to a body part(s).The nervous system is made up of two parts- the peripheral nervous system and the central nervous system. The peripheral nervous system is a system outside the brain and spinal cord and it connects the central nervous system to the rest of the body. The central nervous system controls…

1. Neurons are the building blocks of the nervous system. Neurons communicate through synapses. The nervous system transmits all messages to the brain. The messaging process moves in one direction to the cell body, where the cell body transmits an electrical pulse to the neurotransmitter this creates an impulse. 2. Throughout the normal day you use multiple parts of your brain. An activity that uses more than ten parts of your brain at once is if you hold your hand over a flame. Your Frontal…

Excitotoxicity is a pathological process in which neurons are damaged or killed due to the excessive stimulation of certain neurotransmitters such as glutamate. This process of excitotoxic neuronal death is known to contribute to the pathogenesis of brain and/or spinal cord injury associated with multiple human diseases such as Amyotrophic lateral sclerosis (ALS). (2) ALS is a progressive neurodegenerative disease that involves both the upper and lower motor neurons. Glutamate excitotoxicity is…

A myloidosis (am-uh-loi-doh-sis) results from mutational folds of the immunoglobulin protein, forming a fibril. A fibril is a product of protein aggregation. It is still unknown what causes these fibrils to form, however scientists know that the folds are found in the light chains, also known as the Lambda chains. This specific immunoglobulinic amyloidosis is also referred to as AL or “primary” amyloidosis. AL amyloidosis is considered to be the most common type of systemic amyloidosis in…

Neuroscientists at the John Hopkins University School of Medicine were able to determine that a group of cells found in the adult brain remain highly active by transforming into insulating nerve fibers. These nerve fibers then formed scars that contributed to tissue repair when they were artificially inserted into a group of mice. Their work brings to light how these multifunctional cells communicate with one another in the central nervous system (CNS), also known as the brain and spinal cord.…
