The spinal cord is the major conduct through the body which motors and sense information traveling between the brain and body. The spinal cord is divided by 5 nerves segments which are: 8 nerve roots (C1-C8), 12 Thoracic nerve roots (T1-T12), 5 lumbar nerve roots (L1-L5), 5 sacral nerve roots (S1-S5), and the coxis nerve root. Conforming to Saab, C. Y. (2006), The Spinal Cord, Philadelphia: Chelsea House, a spinal cord injury is a trauma that may result in loss of sensation or motor function or…
disease. This is because, Lou Gehrig, a famous New York Yankees baseball player, was unfortunately diagnosed with amyotrophic lateral sclerosis and died in 1941. ALS is a detrimental condition that begins with the degeneration of motor neurons in the spinal cord, brain stem, muscles, and cerebral hemispheres (Martini, Nath, & Bartholomew, 2015). Motor neurons are nerve cells which act as conducting units and essential communication links between the nervous system and the voluntary muscles of…
ever noticed early enough for anything to be done, as the first onset of symptoms (slurring of speech, muscle weakness, cramping) are often ignored. The symptoms are caused by the motor neurons in the muscles not receiving signals from the brain or spinal cord due to neuron death in those areas.. Due to the tissue death, muscles begin to atrophy and harden. This causes swallowing and breathing to be more difficult; the most common cause of death is respiratory failure, most likely caused by…
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 cord’s lower neurons to be sent out to the motor neurons in the rest of the body. In patients with ALS, both of the…
Introduction When you walk in to “unknown territory”, with the aim to perform, goal setting is incredible important and useful. It first and foremost creates clarity of what I want to achieve, but it also allows me to explore different perspectives of how I best can achieve this goal. My goals for CP to have been as following: - I am building a practice of 20 public practice members by the 23.Desember.2016, through referrals and health talks. - I am motivating my patients by providing…
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 central and peripheral nervous system. This tissue conducts nerve impulses and is composed of neurons. The brain sends messages to the spinal cord the peripheral nerves all over the body that serve to control organs and muscles. The spinal cord is a…
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…
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…
the brain and the spinal cord, the central nervous system is one of the three parts of the nervous system in human body. This system is responsible for information and action processing. It coordinates the response to a stimulus by integrating sensory information and responding properly in the environment. The brain, as the control center of human body, interprets the sensory information (sight, sound, smell, taste and touch) from all parts of the body. On the other hand, the spinal cord is in…
through the process of repetitive learning. After a focal brain injury, the degree of damage to the corticospinal tract correlates to the ability to recover motor function. If the pathway from the primary motor cortex to the motor neurons in the spinal cord is disrupted, secondary motor areas of the brain will be recruited. Secondary motor areas are less numerous and less excitatory; therefore, they will contribute to motor recovery, but will not provide exact substitutions for projections…
