be grouped together to form nerves, which are the primary organizational structures in one major branch of the nervous system, the peripheral nervous system. This is in contrast to the central nervous system, which consists of the brain and spinal cord. The peripheral nervous system can be sub divided into the somatic and autonomic nervous systems, the latter of which can be further sub divided into the sympathetic and parasympathetic nervous…
The defining characteristic of ALS is the death of the upper and lower motor neurons in the brain, brain stem, and spinal cord of the brain. Prior to their destruction, motor neurons develop protein components in their cellular bodies and axons. These components are often combined with and combining one of the proteins associated with ALS: SOD1, TDP-43, or FUS. These components…
Imagine being stuck in a body that cannot move, or even manage to form words. People suffering from Amyotrophic Lateral Sclerosis (ALS, Lou Gehrig’s disease) deal with these debilitating symptoms every day, until they eventually pass away. ALS is a fairly common disease, with more than 12,000 people in the United States experiencing it and 15 people being diagnosed with it every day (“Fact Sheet,” 2014). Researchers are desperately searching for a cure, or even an effective treatment for the…
acidic protein (GFAP), cellular hypertrophy, and development of a pronounced stellate morphology (Lee et al., 2000; Liu et al., 2000; Messing and Brenner, 2003). Both beneficial and detrimental elements of astrogliosis have been described. In spinal cord injury (SCI), the stellate processes of astrocytes interdigitate to form a dense plexus that creates a physical and molecular barrier to nerve regeneration (Fitch and Silver, 2008; Ridet et al., 1997). Chronic demyelinated plaques in multiple…
and Symptoms ALS stands for Amyotrophic Lateral Sclerosis, also known as Lou Gehrig's disease. According to the ALS association they describe the disease as "a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord." This awful disease takes over from the outside in. The disease begins by affecting the body's voluntary muscles such as a person's arms or legs. Cramping and twitching of the muscles can occur as they begin to diminish. While the outer…
injury/possibilities • Unconsciousness - This occurs if the casualty is not responding to Aid being performed • Disorientation - Is caused when the casualty is unaware or unable to understand or respond clearly • Loss of feeling - This may occur if the spinal cord has been damaged. This may result in short or long term damage to the casualty • Loss of control of limbs - Due to brain or spinal damage the casualty may not be able to have direct control of the function of their limbs • Sever…
axial skeleton, 80 bones that comprise the head, neck, and trunk Theappendicular skeleton, 126 bones that form the extremities. Functions • The skeletal system provides protection for many of the vital organs, such as the heart, brain, and spinal cord. • The skeleton provides support for the soft tissues so that erect posture and the form of the body can be…
(Amyotrophic Lateral Sclerosis) is a degenerative disease that affects the neurons responsible for voluntary muscle control. Motor neurons are responsible for movement and to cause movement need to receive electrochemical messages from the brain and spinal cord(the central nervous system). When the brain sends a message to the rest of your body telling it how to move, the message first starts in the brain. These neurons in the brain, called upper neurons, then send the message to the spinal…
track of the baby’s heart rate began setting off an alarm. I glanced over and knew that this had turned into a dire situation. The doctor rushed in and checked my cervix. “That is the cord. Not the baby” A feeling of pure panic filled the room. I knew it was a cord prolapse. She tried to push the umbilical cord back up into me, but the baby’s heart rate dropped again. She looked at my husband and yelled “Ryan, push that red button on the wall now!” I knew what was about to happen, but I…
explain a few things. All truths are parallel! Why does the Bible mention the umbilical cord? Unlike like humans, there is nothing that God mentions in His word that is unnecessary. Most Bible translations unmistakably refer to the umbilical cord as the navel or navel string. When the Bible talks about the umbilical cord it is often with a dual meaning. In the natural, throughout a woman's pregnancy the umbilical cord functions as the connection between the baby and the placenta, which is a…
