Question

select the words and phrases in each blank to accurately complete the sentences.

1. the reflex that results in quick contraction of the same muscle stimulated is called the (click to select) reflex.
2. a reflex hammer striking the tendon is the (click to select) that triggers the (click to select).
3. the afferent neuron synapses with the (click to select) in the integrating center.
4. this makes it a(n) (click to select) reflex arc.
5. if we are using the patellar ligament as the example, the quadriceps muscles are the (click to select).
6. the antagonists will be inhibited. this is an example of (click to select).

effectors
efferent neuron
flexor (withdrawal)
interneuron
monosynaptic
polysynaptic
receptor
reciprocal inhibition
stimulus
stretch

Explanation:

1. The stretch reflex causes quick contraction of the stimulated muscle.
2. A reflex - hammer striking the tendon is a stimulus that triggers a reflex.
3. In the integrating center, the afferent neuron synapses with the interneuron (in polysynaptic reflexes) or directly with the efferent neuron (in monosynaptic reflexes). Here we assume a more general case with interneuron as a possible option.
4. A simple reflex arc with one synapse between afferent and efferent neurons is monosynaptic.
5. In the patellar reflex example, the quadriceps muscles are the effectors that produce the response.
6. When antagonists are inhibited during a reflex, it is an example of reciprocal inhibition.

Answer:

1. stretch
2. stimulus; reflex
3. interneuron
4. monosynaptic
5. effectors
6. reciprocal inhibition
