Question

What type of connections are formed between group Ia afferents and the alpha motor neurons that project antagonistic muscles that would cause flexion of the leg and thus prevent the myotatic reflex?

a. Excitatory connections
b. Inhibitory connections
c. Bipolar connections
d. Unipolar connections

Answer 1

The connections formed between group Ia afferents and alpha motor neurons that project antagonistic muscles and prevent the myotatic reflex are inhibitory connections.

Step-by-step explanation:

The connections formed between group Ia afferents and alpha motor neurons that project antagonistic muscles and prevent the myotatic reflex are inhibitory connections. Inhibitory connections decrease the activity of a neuron, which in this case would decrease the activity of the alpha motor neurons that would cause flexion of the leg. By inhibiting these motor neurons, the myotatic reflex is prevented and flexion of the leg is inhibited.
