Step by step
Solved in 3 steps
- List and describe the two types of cells found in the nervous system. Discuss, in detail, how neurons communicate with each other, including the role of neurotransmitters. Include a description of how different neurotransmitters mediate behaviors and cognitive processes. Watch this Sandrine Thuret’s “You can grow new brain cells. Here’s how” and Sebastian Seung’s “I am my connectome” and summarize, in detail, the main points. Discuss what each video tells us about the function of neurons in creating our thoughts and behaviors. What do you personally think are the most important ideas from each video? Why? Define the terms sensation and perception. Watch the “Do we see reality as it is?” and “Your brain hallucinates your conscious reality” videos and describe the main points of each video in detail. Discuss what the textbook says about how the brain constructs our perceptions of the world. With the information from the videos and textbook, how accurate or “real” do you think our…Which of the following statements regarding the functions of the nervous system is/are true? Check all that apply. Check All That Apply The nervous system is an organ system dedicated to control and coordination of body cells. The nervous system communicates via hormones. Sensory nerve endings transmit messages to the spinal cord and brain. The nervous system's major subdivisions are the CNS and PNS. The nervous system responds slowly and relies on the blood stream to carry its neurotransmitters.Which of the following statements about action potentials and information transmission in the synaptic cleft is FALSE? 1. Action potentials determine the amount of neurotransmitters that are released into the synaptic cleft 2.Action potentials ultimately result in more calcium leaving the target cell at the postsynaptic membrane 3. Action potentials determine the duration that neurotransmitters are released into the synaptic cleft 4. Action potentials ultimately result in more calcium entering the neuron at the axon terminal
- The overall word limit for this task is 500 words (+/-10%). You must cite the sources that you use in-text and provide a reference list. Question 1 (AC 2.1) Examine the diagram which illustrates how the body controls homeostasis. Input: Information sent along afferent pathway to Receptor (sensor) 2 Change detected by receptor 1 Stimulus: Produces change in variable Imbalance Control center Variable (in homeostasis) positivenegative-feedback-mechanisms/(accessed 06/01/20). Imbalance 4 Output: Information sent along efferent pathway to Effector 5 Response of effector feeds back to influence magnitude of stimulus and returns variable to homeostasis Image source: https://anatomyandphysiologyi.com/homeostasis- a) Receptors (sensors) form the first part of the control mechanism. What is a receptor? Provide an explanation then give one example of where a receptor is found, explaining its role is in monitoring homeostasis. b) Draw a simple summary diagram displaying the different levels of…We regularly make conscious decisions to make specific muscular movements. For example, when using the touch interface of your phone, you make a conscious effort to scroll up and down the screen using your finger. In contrast, there are many muscular movements that cannot be controlled voluntarily. For example, you cannot make your heart stop by thinking about it. Which of the following statements correctly identifies the parts of the nervous system that are involved in voluntary and involuntary actions, respectively? Select one: a. Motor neurons of the somatic nervous system and motor neurons of the autonomic nervous system b. Motor neurons of the autonomic nervous system and sensory neurons of the somatic nervous system c. Sensory neurons of the somatic nervous system and sensory neurons of the autonomic nervous system d. Sensory neurons of the peripheral nervous system and motor neurons of the autonomic nervous system1.) What is the general understanding of biological processes, including depolarization, nerve impulse transmission and synaptic transmission 2.) what is integrating a sense (ie. vision hearing etc.) into knowledge of reflex arcs and then arranging the events in order they would occur 3.) how an external substance would change the distribution of ions in a resting membrane and alter the electrochemical response 4.) identifying the names and locations of glands th
- Alcohol addiction is a condition in which a person experiencesdependent on alcohol and difficult to control its consumption. On the other hand, excessive alcohol consumption in the long term can cause disturbances in brain performance, including disturbances in memory, attention, coordination, and locomotion. How does alcohol affect the functioning of nerve cells and the central nervous system? What is the mechanism that occurs? Based on information from the literature, analyze what will happen to coordination and locomotion in someone who is addicted to alcohol and consumes large amounts of alcohol over a long period of time.The autonomous nervous system regulates involuntary functions of the body and can be subdivided into the sympathetic and the parasympathetic nervous system. Both of these systems control the same group of body functions, but have opposite effects on the functions they regulate. The sympathetic nervous system prepares the body for intense physical activity like the fight-or-flight response. The parasympathetic nervous system has the opposite effect and relaxes the body and inhibits or slows many high energy functions. Which of the following involuntary effects in the body are brought about by the sympathetic nervous system during a fight-or- flight situation? i. Increased salivation ii. Increased digestion ii. Loss of bowel and bladder control iv. Body shivering Сrying Pupil dilation B. i, iv and v V. vi. A. i, ii and vi C. iii, iv and vi D. iii and vMultiple sclerosis (MS) is a disorder that causes the destruction of myelin sheaths surrounding neurons. People with MS display many symptoms, including slurred speech, double vision, and poor muscle coordination. What is the direct effect of MS on nerve impulse transmission? Select one: The movement of impulses along neurons is slower than normal. Dendrites cannot be stimulated by acetylcholine, therefore impulses are not generated in neurons. The threshold level of stimulation for neurons is greater than normal. Axons cannot sectete acetylcholine, therefore impulses are not able to travel across synapses. O
