Acetylcholine has two types of receptors: muscarinic and nicotinic, these receptors are functionally and structurally different. Nicotinic receptors are ionotropic, meaning that ions flow through it when acetylcholine binds to it. It acts as a channel for the ions that cross it, especially sodium, and this causes the depolarization of the cell. There are two types of nicotinic receptors formed by different subunits, N1 are found in the neuromuscular junctions allowing muscle movement, and N2 is…

1. Discuss what a neuron is and the functions of its basic parts (dendrites, soma, axon, myelin sheath). A neuron is a nerve cell. There are about 10,000 specific types of neurons, but there are three most common neurons: sensory, motor, and interneurons. A sensory neuron sends signals to help your brain understand what is going on around you in your environment. Sensory neurons are what make up your senses, (smell, touch, see, taste, and hear.)…

mediators and enzymes also sensitize the nociceptors and stimulate A delta and C fibers, nerves that carry the pain signals. A constant influx of these mediators and enzymes cause the nerves to respond to lower levels of these chemicals, leading to an increased number of action potentials and thus an increased sensation of pain (Chapman, 2010). It has been postulated, “repeated stimulation of peripheral nociceptors produced changes in the dorsal horn neurons of the spinal cord... Epidural…

be banned The International Labor Organization estimates that more than 250 million children are involved in child labor. The definition of child labor is work done by children who under the age of 15. Most people think that childhood memory, potential and dignity of children are deprived by child labor. Additionally, it can have some impacts on child’s physical, mental and educational development (kweifio-okai 2015). But, in my opinion, child labor is necessary for poor families to survive,…

(NCBI Bookshelf .A service of the Nation Library of Medicine.)Astrocytes are mainly restricted to the brain and spinal cord. Their main function is to keep chemical environments for neuronal signaling balanced. Oligodendrocytes are our lipid-rich wrapping found in our nervous systems. Myelin has important effects on the speed of action potential conduction. Microglial cells are much smaller cells derived from hematopoietic stem cells. These cells have a lot in common with macrophage tissue. They…

The authors created the Accelerated Sensor of Action Potentials 1 (ASAP 1) using a green fluorescent protein source on the extracellular side of the plasma membrane to highlight the membrane potential changes as demonstrated by the fluctuation in the fluorescent brightness. Neuronal action potentials generated are monitored up to 200 Hz in frequency using this device. The general purpose of this experiment was to further understand information processing in the brain and how brain activity is…

However, I believe the ketogenic diet has so much potential and promise in the future of medicine for the reason that it does not come in a pill or a liquid medicine bottle. There is no long list of side effects, risk of overdose, or prescription needed with the ketogenic diet. We have become so attached…

occurring set of chemicals with vast potential toward a variety of applications. These toxins are produced by countless different species of animals: amphibians, insects, arachnids, and even birds, just to name a few. Neurotoxins, a specific class of toxins, act by impairing or artificially enhancing neurotransmission at the pre-synaptic or post-synaptic level (Camp & Gilbert, 2014, para. 1-5). Neurotoxins affect an animal’s central nervous system by disrupting the flow of action potentials.…

Important Vocabulary (highlighted in the handout): Stimulus, neurons, dendrites, neurotransmitters, axon, myelin, action potential, graded potential, transmembrane potential, neuroglia, cerebrum, spinal cord What is the central nervous system? It’s a system which consists of the nerves in the brain and spinal cord. This system only makes up about 3% of a human’s body weight but serves a vital function, gathering information about and reacting to its environment and any stimulus. Don’t Shoot the…

Our logic for choosing kinesin for developing CNS therapeutics is based upon our own research, which found that kinesins are transcriptionally upregulated during memory storage and that they are both necessary and sufficient to induce long-term memory storage (LTM) in the marine snail, Aplysia californica (Puthanveettil et al., 2008; Fig 1). Furthermore, other researchers have also discovered that an increase in specific kinesin function in the mouse forebrain improves working memory (Wong et al…
