Fish’s consist of a diverse amount of species each known for their characteristics that set them apart from the rest. The characteristics that make the general understanding of a fish are, vertebrate, aquatic, Gills rather than lungs, paired limbs(fins) for locomotion, and are covered with scales. When we see fishes in aquariums we have an irresistible urge to tap the glass, and in doing so, a lot of the fishes get startled and move away performing a sequence of steps called an c-start used as…

Potassium channels (KC) are selective transmembrane proteins that allow K+ ions flow down an electrochemical gradient across cell membrane, thus controlling plasma membrane potential in both excitable and non-excitable cells (Szabo, Zoratti&Gulbins, 2010). Evolutionarily conserved KC family is one of the larges and most diverse of ion channels (Table1). Its diversity comes not only from a large number of genes coding for main subunits (over 80 mammalian genes). Many other processes such as…

neuropathy is a condition which impacts the peripheral nervous system and impacts the communication between the brain and spinal cord to the other areas of the body. Neuropathy can be caused by damage to the axons or the myelin sheath that provides a protective coating and a form of insulation to the axon. If the connections between the main brain and spinal cord are severed, there are certain symptoms that occur including miscommunication between muscles and the neurons that react to the…

2012 study of the California Rialto Police Department body-worn camera project, led by Chief of Police William Farrar, involved a random controlled trial in which half of the department’s 54 patrol officers were randomly assigned to wear the TASER AXON body-camera system. In total, the study assigned 988 shifts into 489 treatment and 499 control conditions over a 12-month period. The Rialto study tested the impact of the cameras on citizen complaints and police use of force incidents, comparing…

Thanks again to everyone who participated in last week’s Plains Area Leadership Conference! I enjoyed seeing everyone and spending some time visiting and listening to your concerns, as well as hearing your ideas for the future. ARS has always had a strong group of individuals leading our local organizations. It’s obvious after reflecting on the two days of the conference that we currently have extremely talented and dedicated individuals serving in key roles throughout the Plains Area. I was…

charge of the membrane potential in graded potentials depends on the strength of the stimulus. Action potentials are long-distance signals of axons only found at the pre-synaptic neuron and graded potentials are short-distance signals of dendrites and cell bodies found at the post-synaptic neuron. Graded potentials are not the nerve signals that travel along an axon, but influence their generation. Graded potential can be either depolarization or hyperpolarization. If threshold is reached,…

(TCO 5) Which of the following is CORRECT concerning REM deprivation? (Points : 5) REM deprivation results in long-term mental illness. REM deprivation only occurs among the elderly. REM deprivation leads to increased amounts of REM sleep on subsequent nights of sleep. REM deprivation can lead to visual impairments. Question 8.8. (TCO 5) The activation-synthesis hypothesis of dreaming states that _____. (Points : 5) the purpose of dreaming is to express…

needs to happen for me to feel a certain way or perform a certain action. In a neuron, it first has to have a certain amount of depolarizing ions for there to be an action potential. When that action potential is reached, charge can be sent through the axon (which is protected by the myelin shealth). As a charge goes through a neuron, vesicles that hold neurotransmitters (that are contained in the presynaptic terminal button) can be then released to the postsynaptic spine. After traveling…

During a concussion, there is a release of a metabolic cascade of neurotransmitters, which causes stretching of cell membranes and neuro axons (Shrey et al., 2011). Neurotransmitters are essentially the highways the brain uses to process information (Willis, 2010). Subsequently there is also an increase of potassium released into the brain tissue, which requires to body to use more energy to establish a balance; during which, there is a slowing of cerebral blood flow, and the brain must…

called alpha 4 integrin and this protein can be found on the surface of white blood cells (NIH, 2015). In addition, PML is a disease that targets myelin and myelin form a whitish sheath around nerve cells. Myelin sheath normally located around the axon of a neuron and it is an important function of nervous system. Also, myelin sheath protects the nerve cells and has a protein that affects the immune system (EMedicineHealth,…
