Question 7

The crossed-extensor reflex integrating center is [dropdown 1] since several sensory neurons synapse with interneurons that synapse with motor neurons.The interneurons excite motor neurons in several segments which is known as a [dropdown 2] reflex.This is a [dropdown 3] since the motor information exits the opposite side of the body from the sensory input.At the neuromuscular junction,[dropdown 4] is released to [dropdown 5] the muscle that will extend.
Dropdown 1 choices:
polysynaptic
monosynaptic
Dropdown 2 choices:
reciprocal innervation
intersegmental reflex arc
Dropdown 3 choices:
contralateral reflex arc
ipsilateral reflex arc
Dropdown 4 choices:
acetylcholine
norepinephrine
Dropdown 5 choices:
inhibit
excite

Accepted Answer

1.polysynaptic
2.int
