Case Study 1
Amy was preparing dinner for her family. As she went to pull the pot off the stove, she touched the burner accidently. When this happened she instantly pulls her finger away and without delay she feels pain. Amy pulled her finger away as a reflex because the burner was hot. This unconscious effort was caused by a combination of five neurons called reflex arc. The reflex arc consist of the receptor, sensory neuron, interneuron, motor neuron, and effector. The motor neuron was responsible for sending information from her finger to her peripheral nervous system. According to the text, the motor neuron transmits an immediate response through the ventral root to the effector organ (Ireland, 2012). The motor neuron carried a signal to Amy 's finger. This receptor neuron is an efferent neuron. Efferent neurons are found in the central nervous system and they are primarily responsible for getting information from the other neurons and then spreading nerve impulse to the responding muscles or glands .
The spinal cord is the key method of communication between the body and the brain. Sensory information go into the spinal cord through the dorsal root and is move to an upward region heading in the direction of the brain. Motor impulses produced in the brain are passed through the downward regions of the spinal cord to the nerves of the body. Reflexes are remarkably fast responses to sensory stimuli, running through the spinal cord from the dorsal root directly to the ventral root and bypassing the brain. This caused Amy to move her finger quickly. Incoming sensory information is transported to an connected neuron in the deepest portion of the spinal cord and then directly to a motor neuron. The reflexes generates to a lif...

... 's neurologist needs to prescribe him a dopamine agonist as treatment because its purpose is to restore appropriate balance of the neurotransmitters dopamine and acetylcholine by increasing levels of dopamine. Dopamine agonists medication that directly mimic dopamine 's activity in the brain and can help treat Glen 's motor symptoms. It is very important to advice Glen 's children to be genetically tested for this disease because usually those at risk for early onset have a family history of it. Early detection of Early Onset Parkinson 's comes with the hope that the debilitating symptoms can be delayed. Additionally, life style changes could be made and it would allow for more aggressive treatment. A positive result may cause loss of job, lack of promotion, and possibly denial of insurance coverage, other worries include financials and care giving (Ireland, 2012).

- Skeletal muscles have the ability to contract whether it be voluntary or involuntary. Purves (2008) describes the motor unit which is comprised of an a motor neuron and striated muscle fibres. These motor units are distributed within the muscle and are responsible for providing the force that is required for generating movement and posture. Purves (2008) explains that the contraction of skeletal muscles is initiated by lower motor neurons (LMN) located in the spinal cord and brain stem. There are two types of LMN’s, gamma motor neurons and alpha motor neurons.... [tags: Neuron, Nervous system, Somatic motor system]

- Fine motor skills, one of the area’s Justin scored low on seems to be connected to ADHD and DCD. Being an observer and administering this ASQ to Justin, my observations of Justin and his attention span and hyperactivity lead me in the direction of not thinking it is necessarily he is incapable of preforming some of the tasks, but that he finds it difficult to concentrate. “ADHD is characterized by persistent symptoms of inattention, impulsivity, and hyperactivity, affecting 3 to 5% of school-age children....

- There are many situations in which one may not consider it “evil” because one did not think he or she did anything wrong; however, it depends on how the victim views the situation. One night, my friends and I decided that we should work on a chemistry lab report together. Someone in my friend’s lab class asked for help, so my friend, Bob, went to go talk to him outside of our hall. One guy in my group suggested that we should lock Bob out, and so we did. Bob did not realize that he was locked out until after he was done speaking with the guy from his lab class.... [tags: English-language films, American films, BDSM]

- According to the lab manual, for the report we are supposed to create two graphs, one with all the points and the second one with only the points in the linear range. As my first graph had all the points in the linear range, no second graph has been created.

- Water is a charged or polar molecule (H+ - O- - H+) that is always moving across cell membranes. Scientists theorize that this is possible because it is such a small molecule or because there are special gap or pores that allow water movement through the cell membrane. The predominant direction of water flow is determined by the concentration of the solutes (non-water molecules) inside and outside of the cell. Water molecules will show a new movement from an area of higher water concentration (& lower in solutes) to an area of lower water concentration (& higher in solutes).... [tags: Lab Report]

- Al-Majed et al. and Nix et al. focused on electrical stimulation and the effects on the regeneration of motor neurons unlike Geremia et al. who questioned the effect of electrical stimulation on sensory neuron regeneration. The same experimental design and simulation protocol was used in both studies. The experimental design and stimulation protocol that was first used in Al-majed et al. offered strength to both the study itself as well as for the Geremia et al. study. The methods and protocol were detailed and comprehensive enough to be reproduced by Geremia et al.... [tags: Action potential, Nervous system, Axon, Neuron]

- Vadim Kavalenko - The focus of our 4th quarter in 9th Grade Science was chemistry. We spent a lot of time in the lab seeing first hand how chemical reactions occur, and continued to focus on the lab report writing process. Our lab and projects included a melting point lab, flame test lab, a pennies to gold lab, and a hydrogen gas lab. Next year students in 10th grade at HIS will study biology. Vadim has made definite progress this year as he has solved his problems with not completing assignments.... [tags: Chemical reaction, Chemistry, Experiment]

- The purpose of the final unknown bacteria lab was to gain a better understanding of what our bacteria was and be able to state what our organism was and why we believe it to be that organism. This final lab report will encompass labs 9 through 13. There were five labs that were conducted in this lab report. The purpose of lab 9 was to use different biochemical tests to identify microorganisms. These tests test for a microorganisms ability to utilize various carbohydrates, broths, and starches, as sources of nutrients and energy.... [tags: Bacteria, Agar plate, Enterococcus faecalis]

- ... The test tubes were labeled as follows: A. Milk and lactase, B. Milk and water, C. Sucrose and lactase, and D. Sucrose and water. We then label our four micropipettes using a sharpie as: milk, lactase, sucrose, and water. Paper towels to rest the micropipettes may be an efficient way to keep the area clean and the micropipettes, and a timer to keep track of time. The four glucose strips to determine the results at the end of the experiment are by far the most important, and of course a lab bench to place the test tubes on....

- Purpose The purpose of this lab was to see firsthand the diffusion of a substance across a selectively permeable membrane. Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration until both concentrations are equal, or as you could more professionally call it, equilibrium. This concept is one that we have been studying in depth currently in Biology class. Procedure We separated into groups of two each, making sure that we had the following materials for the lab: graduated cylinder, plastic sandwich bag, starch solution, twist tie, 500-mL beaker, iodine solution, and a pair of goggles and an apron (for the person handling the iodine solut...
