Cord blood

Walking is assisted by the brain, spinal cord, muscles, reflexes and receptors. The act of walking begins from brain and spinal cord which is the planning on how to walk. More precisely, it starts from the cerebral cortex. Cerebral cortex is the region of decision-making and it initiates voluntary response, in this case, the act of walking. Basal ganglia are also responsible for voluntary locomotion. It requires the knowledge of the body’s position in space (where am I walking to) and what…

syndrome causes complete paralysis with the exception of eye movement, however the patient is completely conscious and aware of surroundings (Pistoia et al., 2016). According to Pistoia et al., (2016), due to the disconnection of the cortex and spinal cord in…

environment. Neurons are known as the messengers of the body. They are the nerve cells that send messages through the nervous system, while the nerve impulses send coded electrical signals from the neuron. The motor neurons carry the brain and spinal cord impulses, to the muscles and the glands, while the sensory…

One of the major channels of the spinal cord is the spinothalamic tract; a sensory pathway. It conveys nerve impulses for sensing pain, warmth, coolness, itching, tickling, deep pressure, and crude touch. (Tortora, 2014-01-22, p. 461). Based on that description and as the name implies, information will travel from the region of stimulation on the skin to the CNS, ultimately landing at its destination at the thalamus; thus, making it an ascending pathway. This pathway is further divided into…

The Truth About ALS and CTE: Can They Be Stopped? Imagine being trapped inside your own body; powerless, unable to do anything on your own. Thinking about old memories and just wishing for the chance to relive those happy moments when you are capable of doing the simplest jobs on your own. That is exactly how a person feels when they have Amyotrophic Lateral Sclerosis or commonly known as Lou Gehrig's Disease. ALS is a fatal neurological disease that attacks the nerve cells, which control one's…

Lou Gehrig’s disease is also known as Amyotrophic Lateral Sclerosis (ALS). ALS is a disease that affects the nerve cells in the brain and the spinal cord. It is a progressive neurodegenerative disease, this eventually leads to death. The patients lose the ability for the brain to control muscle movement. Since most motor neurons are lost, the patients may eventually become completely paralyzed. Motor neurons can no longer send signals or impulses to the muscle fiber resulting in no muscle…

5 Spinal Bifida 1. Definition: • A birth defect that affects the neural tube. • The neural tube is the embryonic structure that ends up developing into the brain, spinal cord, and the tissue that surrounds and encloses them. In babies diagnosed with spinal bifida, the neural tube does not form correctly and is left open, causing defects. 2. What are the causes/risk factors: • Experts have not figured out what the exact cause of this disorder. Most think that the link is genetic or…

signals between different parts of the body. It has two components; the central nervous system and the peripheral nervous system. The nervous system is an intricate part of your body and life that 's made up of two separate systems, the brain, and spinal cord. During prenatal growth, the nervous system experiences many changes to gain its compound structure. The events of this early development include the growing of billions of neurons, axons, and the formation of thousands of…

motorneurons, which are situated in the spinal cord, and the frequency of the activity is most enhanced in 19 hpf embryos (Saint-Amant and Drapeau, 1998). Supraspinal input is not depended upon and neurotransmitters such as glutamate and glycine do not regulate this form of locomotor behaviour (Saint-Amant and Drapeau, 2001 cited in Downes and Granato, 2005).…

Introduction A vertebrate is characterized by the vertebral column as it is part of their axial skeleton. Its main function is to act as a communication pathway between the brain and the body of the vertebrate. Usually, vertebrates have a fixed number of vertebral column, but there are variations in the number of vertebral columns within the cetacean species. Dolphins are vertebrates and are one of the fastest swimming species due to their morphological stability. The morphology can determine…
