Alpha motor neuron

1. The Jendrassik maneuver played a major role on the patellar reflex. One of the prevailing hypotheses has to deal with the alpha-gamma co-activation theory. It states that the alpha motor neurons activates the motor tone, which leads to the spindles providing feedback to the brain. This process is done by the gamma motor neurons, who are in charge of controlling the stimulation of the cerebellum. Also, both the alpha and gamma motor neurons meet at the same effector muscles. Furthermore, when the extrafusal fibers of the muscle spindle contract, the intrafusal fibers change length in correlation to the muscle tone to activate the feedback to the brain, which is done by the gamma neurons. The feedback process is performed by afferent neurons located in the spinocerebellar tract, in which they relay the message to the central nervous system regarding the length and tension of the muscle fibers.…

This bond that the soldiers formed helped them to survive, and helped the men of Alpha Company to cope with the war after they returned to the United States. "The bond that men form with each other in the heat of battle is incomprehensible to those who have not experienced warfare for themselves...You make close friends. You become part of a tribe and you share the same blood - you give it together, you take it together." (O'Brien, 192) This bond of friendship helps the men of Alpha…

Case Study: Hereditary Canine Spinal Muscular Atrophy Genetic Background Hereditary canine spinal muscular atrophy (HCSMA) is proven to be an autosomal-dominate disease that affects most noticeably the Brittany spaniel (Pinter MJ, Waldeck RF, Wallace N, & Cork LC, Motor Unit Behavior in Canine Motor Neuron Disease, 1995). HCSMA originated as a spontaneous mutation in the Survivor Motor Neutron gene found in the purebred Brittany spaniel population (Ericsson. A & Rubin. C, 2012). Due to the…

is a loss of motor neurons in the brain and spinal cord, this disease is incurable therefore leading to paralysis and death. The particular two studies discussed will be based on how biomarkers (a tool used by scientist to determine the biological pathways and the progress of the disease) can help find a cure for ALS by creating an effective drug and most importantly early detection. Mice were used as a transgenic model once they had SOD1 G93A gene mutation they discovered the mice developed…

All throughout grade school, I have learned how African American men greatly influenced our society. Mr. Andrew Young, Mr. Thurgood Marshall, and Mr. Jessie Owens are all prime examples of men who were essential to the growth and development of the African American race. These men have played a large role in breaking social constructs within our communities. They are prominent figures in history, and furthermore, members of Alpha Phi Alpha Fraternity, Incorporated. The majority of the men I…

As many of you probably haven’t heard of the Divine Nine which consist of 9 different African American fraternities and sorority organizations which has been a pivotal part of African American history and culture since the early 20th century. Which are the Alpha Phi Alpha Fraternity, Alpha Kappa Alpha Sorority, Kappa Alpha Psi Fraternity, Omega Psi Phi Fraternity, Delta Sigma Theta Sorority, Phi Beta Sorority, Sigma Gamma Rho Sorority, and Iota Phi Theta Fraternity. In the early 1900s, African…

The main composition of this group is religion being a church group. We all go to Antioch community church and consider ourselves either Christians or Jesus Followers. This was an intentional result from careful recruiting at Sunday service or by ways of socialization or assimilation once a person starts to attend the Lifegroup or Section. I know when I first started to attend Lifegroup; I was not a devoted Christian. I believed in God and Jesus, but practiced no rituals or norms associated with…

Alpha Males: Natural Born Leaders There are several movie characters that hold great standing, but then, they are fewer characters that possess a reputation that is erected on just moments that would reflect on how I feel about myself; Robert DeNiro is that person whose on-screen body language makes him a natural born leader, and the mannerisms help to boost his alpha male persona, which propels his characters to another level. Furthermore, he captures the personalities that he is projecting,…

were this way were before the war broke out. Before the war broke out there was balance between dark and light, we were a thriving pack of 34 wolves and growing but then the darkest pack in the forest the Demons took over our land killing all of our members including the alpha female, male, and the beta female now I’m the only alpha left in the pack, now 6 of us left, my beta Max, the protector Jordan, and the 3 omegas, Thunder, Winter, and Fall. My parents were the alphas before they were…

increasing in different career fields, which is why knowing how to correctly use technology is beneficial to professionals. Communication is a skill needed to work with your employer and others, such as students to successfully complete tasks and cater to students’ needs. In student affairs, possessing the skill “student conduct” is important because you are working day-to-day with students. The skill “personnel management” would be beneficial for senior student affairs officers when managing…
