Definition Reflex tests are simple physical tests of nervous system function. Purpose A reflex is a simple nerve circuit. A stimulus‚ such as a light tap with a rubber hammer‚ causes sensory neurons (nerve cells) to send signals to the spinal cord. There‚ the signals are conveyed both to the brainand to nerves that control muscles affected by the stimulus. Without any brain intervention‚ these muscles may respond to an appropriate stimulus by contracting. Reflex tests measure the presence and

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

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

spinal nerves and the spinal cord‚ include: 1- extensor reflex: leg proprioceptors trigger limb extension 2- myotatic (stretch) reflex: muscle stretch is resisted by reflex contraction of the muscle 3- withdrawal (flexion) reflex: limb flexes to withdraw from a noxious stimulus A spinal reflex is a stereotyped‚ automatic motor reaction to an input signal. The monosynaptic myotatic stretch reflex is the most crucial reflex for the maintenance of the erect body posture in humans.

The Brain and Reflex Behaviors The growth of the brain is a lifelong process fundamental to physical‚ cognitive‚ and emotional development. Building of the brain The functions of the brain and the reflexes derive from the central nervous system. The central nervous system is located in the brain and the spinal cord‚ which is a bundle of nerves running through the backbone. The nervous cord in spine then branches out into a peripheral network of nerves extending to every part of the body

* | * Moro reflex - The Moro reflex is often called a startle reflex because it usually occurs when a baby is startled by a loud sound or movement. In response to the sound‚ the baby throws back his/her head‚ extends out the arms and legs‚ cries‚ then pulls the arms and legs back in. A baby’s own cry can startle him/her and begin this reflex. This reflex lasts about five to six months. * Grasp reflex - Stroking the palm of a baby’s hand causes the baby to close his/her fingers in a grasp
