Question 8

In a ________ reflex, a sensory neuron synapses directly on a motor neuron.

Accepted Answer

The answer of In a ________ reflex, a sensory neuron...

Question 9

After stretching an intrafusal fiber, the next event is

Accepted Answer

After stretching an intrafusal fiber, there will be an increased firing of action potentials along the associated sensory neuron, leading to a reflexive contraction of the extrafusal fibers and an increase in muscle tension. This is the basis of the stretch reflex, which helps to maintain muscle tone and joint stability. The other answer choices are not accurate in describing the immediate effects of intrafusal fiber stretching.

Question 10

Question 12

Ten-year-old Tina falls while climbing a tree and lands on her back.Her frightened parents take her to the local emergency room where she is examined.Her knee jerk reflex is normal and she exhibits a negative Babinski reflex.These results suggest that

Accepted Answer

The knee jerk reflex and Babinski reflex are both tests of spinal reflexes, and normal results suggest that there is no damage to the spinal cord. Thus, Tina has suffered no damage to her spinal cord.

Question 15

A muscle at rest exerts no tension.Is this statement True or False? Explain your answer.

Accepted Answer

Normal muscles maintain a resting tension known as muscle tone.

Question 16

How does the stretch reflex protect a muscle?

Accepted Answer

The answer of How does the stretch reflex protect a...

Question 17

When there is a resistance to the movement produced by a given limb muscle,

Accepted Answer

When there is resistance to movement, the body compensates by increasing muscle tone and recruiting more motor units to overcome the resistance, thus enhancing the force generated by the muscle. This is a fundamental principle of how muscles respond to increased demands, ensuring that sufficient force is produced to move against the resistance.

Question 18

Name the components of a reflex pathway, and describe generally how a reflex works.

Accepted Answer

The answer of Name the components of a reflex pathway,...
