The Reflex Arc Reflex actions are the way the body responds rapidly to painful situations or the threat of painful situations. The reflex are is the mechanism by which the response occur The reflex arc is the name given to the pathway (or circuit) along which the initial stimulus and the corresponding response message travel There are five parts to a reflex arc: 1.) The Receptor‚ which receives the initial stimulus 2.) The Sensory (afferent) Nerve‚ which carries the impulse to the spinal cord or

and Physical Effects on Patellar Reflex May 8‚ 2014 Introduction The purpose of this experiment was to monitor our body’s reaction to stimulation and see how our nervous system‚ specifically the somatic nervous system can affect the patellar reflex. “The patellar reflex‚ also known as the knee jerk reflex is an example of a simple two neuron‚ monosynaptic reflex arc”(Marieb‚ Mitchell and Smith‚ 2014). We tested the strength of the knee reflex activity and whether it was affected

High Dive Part I – Write up 1. I first used the problems and the obstacles that were given‚ the cart‚ the Ferris wheel‚ location of the diver and time. All of these four of these constraints contributed to my four equations. On page 46 and 47‚ Homework 13‚ this is where everything comes together to make the final piece. This is basically my verification that I am supposed to have no more than four equations and no less. When having four equations I have to have four variables. This allows me to

It is very obvious that the team members of Rankin were all suffering from stress or even worst the burnt-out syndrome. Generally‚ stress is real and it is painful for everybody concerned. It damages the individual‚ the team and the business. If Rankin would watch out for it‚ address the problem

in. 2. Find a friend and test the patellar reflex. a. Which muscle contracted? The muscle that contracted is the quadriceps. b. What nerve is carrying the afferent impulse? The nerve that is carrying the afferent impulse is the sensory nerve of the femoral nerve. c. What nerve is carrying the efferent impulse? The nerve that is carrying the efferent impulse is the motor nerve of the femoral nerve. 3. Find a friend and test the plantar flexion reflex. a. Describe the response. The response to

Reflex acts were one of the first human reactions to being studied. Descartes was the first beginning a study model of reflex acts‚ this to be able to demonstrate that the body worked like any other machine. Another scientist in studying this phenomenon‚ Robert Whytt. He was a Scottish physicist and physicist. He inclined his research around action-reflex‚ differentiating voluntary and involuntary movements. Describing the pupil reflex to light (reflecting Whytt)‚ he further proposed that the arches

In this experiment‚ we are trying to find the effect of ERα in kisspeptin neurons‚ so we are going to investigate situations where ERα is present or absent. The model we use for this experiment is WT mice with ERα intact in kisspeptin neurons‚ and KERKO mice where ERα is knocked out in kisspeptin neurons. Then the researchers compare various features between WT mice and the knock-out mice 1. The first factor they compared between KERKO and WT mice is how is the presence /absence of the ERα

Mammalian Kidney Investigation Background Information: The kidneys are dark red bean -shaped organs that are a very important pair of organs that perform many functions. The kidneys have a convex side and a concave side. They are each about the size of a fist. The kidneys are located near the middle back of a human‚ just below the rib cage‚ one on each side of the spine. One kidney is located below the spleen on the left side of the body‚ whereas the other kidney is located just below the liver

The book uses the scuba diver analogy well in order to clarify the four different type of strategic thinkers. “Strategic thinking is the generation and application of business insights on a continual basis to achieve competitive advantage.(p156‚164)” The four types of strategic thinkers are Beach Bums‚ Snorkelers‚ Scuba Divers‚ and Free Divers.

most basic circuits is a reflex arc‚ which occurs rapidly in response to inputs from the sensory neurons and consist of only one or a few afferent and efferent cells. Such a response is very quick and automatic. Reflexes are among the oldest and most important features of nervous systems‚ because they allow animal to respond quickly to potentially dangerous events.
