Several of the events that occur between the time a physician strikes apatient’s patellar tendon with a rubber hammer and the time the quadriceps femoris contracts (knee-jerk reflex) are listed below:(1) increased frequency of action potentials in sensory neurons(2) stretch of the muscle spindles(3) increased frequency of action potentials in the alpha motor neurons(4) stretch of the quadriceps femoris(5) contraction of the quadriceps femorisWhich of the following most closely describes the sequence ofevents as they normally occur?a. 4,1,2,3,5 c. 1,4,3,2,5 e. 4,2,3,1,5b. 4,1,3,2,5 d. 4,2,1,3,5
Identify the Golgi tendon reflex (which is an innate reflex) as (a) spinal or cranial, (b) somatic or visceral, (c) monosynaptic or polysynaptic, and (d) ipsilateral or contralateral.
Distinguish between the following types of reflexes:
A) Somatic vs. Visceral (autonomic) reflex
B) Monosynaptic vs. Polysynaptic reflex

- A friend who works in a research lab is conducting an experiment to study motor movement. First the animal undergoes spinal transection at T5. Then, the animal is trained to walk on a treadmill while supported. Finally, GABA antagonists are injected into the lumbar enlargement of the spinal cord. After treatment of the drug, what motor response would you expect? Question 5 options: A) The animal no longer has proper functioning of back or front legs while on the treadmill B) The animal no longer has coordinated movement of the front legs while on the treadmill C) The animal no longer has coordinated movement of the back legs while on the treadmill D) The animal can walk normally on the treadmill (with support)arrow_forwardWhat are the components of a reflex arc and what is the difference between a somatic motor reflex and a visceral reflex arc?arrow_forward(b) (1) Explain the term reflex action.

Myotatic (stretch reflex)b. Autogenic Inhibition (Golgi tendon organ reflex)c. Flexor Reflex 2) You stimulate an alpha motor neuron and measure the force of contraction in a control muscle from a mouse. You then add Substance X, a newly synthesized product from your organic chemists. You observe that there is adecreased force of contraction following the same type of motor neuron stimulation.a. Draw your experimental setup and what force you measure before and after administering Substance X.Hint: You’ll need to include something to stimulate the muscle and something to measure the force. Whatyou measure is force upon stimulation (mN, milliNewtons) before and after addition of X.b. Hypothesize one way that Substance X could be inhibiting muscle contraction.
