There are several key differences in the reflex pathways of the somatic and autonomic systems. Select all of the true statements below. Interneurons are only in the somatic reflex. Skeletal muscles are only in the somatic reflex. Pre-Ganglionic neurons are only in the autonomic reflex. Motor neurons are only in the autonomic reflex. Question 2 Which of the following is a feature specific to the autonomic nervous system? Synapse in the central nervous system. Acetylcholine. Sympathetic chain ganglia. Excitation of skeletal muscles. Nicotinic receptors.

In the knee-jerk reflex, $a .$ spinal interneurons inhibit the motor neuron of the antagonistic muscle. $b$. activity in the stretch receptor neuron causes contraction of the leg flexor muscles. $c .$ the cell body of the motor neuron is in the dorsal horn of the spinal cord. $d$. action potentials in the sensory neuron release inhibitory neurotransmitter onto the motor neurons. $e .$ the sensory neuron forms a monosynaptic loop with the motor neuron to the antagonistic muscle.
Which of these is not characteristic of a monosynaptic reflex? Includes an interneuron All statements are characteristic of a monosynaptic reflex Is a fast process includes two neurons Has one synapse
