16. A tap on the patellar tendon at the knee joint is used to test the knee-jerk reflex. All of the followings are incorrect, except ---------------------. A. This reflex involves relatively simple neuronal circuits B. The reflex starts with the 1a sensory neurons of the muscle tendon C. There is an inhibitory stimulus to the motor pool of the extensor muscle D. There is a stimulation of the excitatory interneuron of the flexor muscle E. Excitation of the flexor muscle fibers causes the knee extension

5) Lower motor neurons are _____________ neurons. A. multipolar B. bipolar C. unipolar D. anaxonic B. bipolar C. unipolar D. anaxonic

If an individual does training with only the right knee extensor muscles, it is common to see increase in strength in knee extension force for the right leg and an increase in strength in the knee extension force of the left leg (although the increase in force is typically not to the same extent as the force increase in the right leg) a.) True b.) False

2. You cut the axon of a single motor neuron innervating the biceps muscle. Which of the following is true?a. The biceps muscle will no longer be able to contractb. Only one muscle fiber in the biceps will be unable to contractc. All muscle fibers in the biceps innervated by that motor neuron will no longer be able to contractd. There will be no effect since each muscle fiber is innervated by multiple motor neurons 3. Which of the following will produce the LARGEST force of twitch contraction? Explain your answer.a. Stimulation of all alpha motor neurons in a muscleb. Stimulation of all alpha motor neurons plus all gamma motor neurons in a musclec. Both stimulations will cause a similar force of twitch contraction   4. A patient, like Ian Waterman, who has lost all muscle proprioceptor neurons. Which reflexes will be absent inthis patient? 5. You have found a new type of sensory neuron that senses ammonia. If this sensory neuron worked like thesensory neurons we studied in class, how…

35. Which of the following sentences is CORRECT? A. Intercalated disc is absent in smooth muscle and skeletal muscle B. The contraction of smooth muscle cells is slow, but they can remain contracted for long periods C. Cerebellar cortex is composed of outer molecular layer, central layer of Purkinje cells, and granule layer D. Ganglia are ovoid structures containing neuronal cell bodies and glial cells supported by connective tissue

Spasticity of the paralyzed muscles in UMN lesions is associated with :-a- inhibition of tendon jerksb- remarkable wasting of the musclec- clonusd- non of the above

Muscle spindles trigger the muscle to   a. lengthen.   b. relax.   c. shorten.   d. remain fixed.

Which of the following statements relating to the developmental aspects of muscles is false? a. All muscle tissue types arise from myoblasts b. Skeletal muscles become amitotic while smooth muscles regenerate throughout life c. Sarcopenia begins by age 30 and is irreversible d. Body strength per unit muscle mass is the same in both sexes  e. none of the above   Which of the following structures is located in the head region of the thick filament myosin? a. actin binding site b. ATP binding site c. ATPase enzyme d. all of the above e. none of the above
