The promise and limitations of using Stem Cell Therapy to treat spinal cord injury. First Name Last Name College Name Introduction Stem cell therapy, otherwise called regenerative drug, is the utilization of undeveloped cells or their subordinates to advance the reparative reaction of sick, useless or harmed tissues. Scientists search for foundational microorganisms in a research facility where these undifferentiated organ-isms are controlled to represent considerable authority in particular…

Essay Submission Assignment #1 1. Discuss the relationship between distribution of muscle fiber type and performance. How might exercise training modify or change a person’s fiber-type distribution? Muscle fibers can be categorized into two main properties, twitch and metabolic properties. The twitch properties consist of slow and fast twitch and metabolic properties consist of oxidative, oxidative/glycolytic and glycolytic (Beardsley, 2017). Slow twitch and fast twitch muscles fibers are…

June 23, 2016 Breakthroughs: Biomedical Research Yishi Jin, a renowned researcher, developed a study called "Neural Development and Axon Regeneration in C. elegans". Her research revolved around axon regrowth and the restoration of mature neurons, problems that arise quite frequently as we, both, age and face unfathomable and unexpected accidents. She utilized C.elegans as the model organism due to the similarities…

named one of the subtype of the nociceptors, and what are the one of four differences in those receptors? (2pts) 1) Mechanical. Thermal. or Polymodal. 2) Morphology of the peripheral ending. Sensitivity to stimulus energy. Diameter of the axon. Whether the axon has myelin or not. 3. Which transient receptor potential (TRP receptors) seem to be involved in the mechanical pain? (1pt) Mammalian TRPA1 channels seem to be involved in mechanical…

Cells Interacting: Astrocytoma in its cancerous form is a situation in which a malignant tumor starts in Astrocyte cells, which have the purpose of protecting nerve cells. As the tumor grows invasively into these cells, it presses on the nerve cells and other parts of the brain. Cancerous astrocytoma will grow very quickly, spreading into other sections of brain tissue. As it does this, it will start to push on the brain itself and stop it from functioning properly. …. Function: The…

The interactions with the taste receptor cells will produce an action potential that will induce an action potential in taste sensory neurons. A neuron has 3 main parts: the dendrite, the cell body, and the axon. Information will be able to move faster in bigger and myelinated axons. In sensory neurons, the action potential is trigger at the dendrite. Each neuron has a cell membrane that encloses each neuron. The cell membrane is semi-permeable which mean certain things can go in and out of…

white fatty covering, Glial cell which insulates and supports neurons. The messages that neurons carry are the nerve impulses called action potentials which travel down axons at different speeds. Neurons are so closely interweaved that it is difficult to see where one ends even with a microscope. These tiny gaps between the axon of the sending neuron and the dendrite or cell of the receiving neuron is called the synapses. Each neuron is a miniature decision-making device, reacting to signals it…

Phenylketonuria is an autosomal recessive disorder and a common metabolic cause of mental retardation. This inborn error of metabolism is characterized by a deficiency in phenylalanine (Phe) hydroxylase activity, due to mutations in the Phe hydroxylase (PAH) gene. Phenylalanine hydroxylase is responsible for converting Phe to Tyr and requires the cofactor tetrahydrobiopterin (BH4), molecular oxygen, and iron for its action (Blau et al., 2010). The reductant, BH4 is maintained in the reduced…

Important components of the neuromuscular junction where muscle innervation occurs include muscle and nerve fibres and motor end plates (Dhoot et al., 2013) whereas a neuron itself consists of a cell body or soma, axon, basal and apical dendrites (Megias et al., 2001). Neurons can be classified as excitatory or inhibitory based on their structure where excitatory neurons are typically pyramidal cells with one apical dendrite and multiple basal dendrites (Megias et…

the central nervous system due to its role in visual integration and function. The optic nerve transfers visual information from the retina to the vision centers of the brain via electrical impulses. Made of about 1.7 million retinal ganglion cell axons, or nerve cells, the optic nerve encompasses the first portion of the visual pathway: from the retina to the optic chiasm. Dimensions The optic nerve itself is a cylindrical structure. Approximately 50mm in length, it can be divided into 4 main…
