- The following image sequence represents the proper order of neurological impulse in the reflex arc. True or falseGive a labeled illustration of a simple reflex arc with its components of the patella tendon tap reflex/knee jerk reflex.Subject: Anatomy and PhysiologyReflexes are often used for diagnosing disorders of the nervous system and locating injured tissues in the body. Describe 2 somatic reflexes and explain the reason why these reflexes can cease to function or function abnormally. Use 4-7 sentences for each. Separate your answer in paragraphs.
- Background: A doctor conducted a patellar tendon (aka knee jerk - covered in lecture, assigned reading, and laboratory) reflex test on a patient. To do so, she tested the patient's knee-jerk reflex by hitting the patient's patellar tendon with a rubber hammer. For this patient, the doctor observed that hitting the tendon caused no knee jerk reflex at all, even after many attempts. Normally, a patient will kick her lower leg after the hammer hit on the tendon. However, the doctor could stimulate contraction of the quadriceps leg muscles using a stimulating electrode that applied a voltage across the muscle. 1) During the examination, the patient got nervous. His heart rate increased. Which of the following would increase heart rate? Group of answer choices a)An increase in parasympathetic neural stimulation to the pacemaker node of the heart b)An increase in sympathetic neural stimulation to the pacemaker node of the heart c)An increase in acetylcholine release by motor neurons…Background: A doctor conducted a patellar tendon (aka knee jerk - covered in lecture, assigned reading, and laboratory) reflex test on a patient.

The doctor, with further analysis, determined that the receptor membranes of the stretch receptors were operating correctly.To do this, she carefully inserted an electrode into a stretch receptor's membrane, near to the location on the membrane where receptor proteins are located. She measured a change in voltage while hitting the tendon with the hammer. With further testing, the…This is a type of signal in the brain that changes when we do an action/movement or when we see someone else do an action/movement:
- A gymnast is able to maintain a steady posture while on a balance beam. In order to maintain balance, the gymnast would need to see the balance beam and determine where her feet are touching it. She would need to control the muscle contractions in her body to ensure she doesn’t fall off the beam. The regions of the brain numbered above that are involved directly in maintaining balance are Answer, Answer, Answer, and Answer. Record your answer in descending (highest to lowest) order.Order the steps of the reflex arc. Hammer hits the patellar tendon. 1 2 3 4 5 Sensory neuron sends signal Stimulus at the receptor Motor neuron sends signal Response occurs at effector Integration neuron (center) processes signals Leg kicks out at the kneeReflex theory can be defined as: a chain of action thought to be triggered by some external stimulus that resulted in an observable movement response.
