One important difference between autonomic neurons and somatic neurons is the presence of?
Autonomic neurons control signals to and from the brain to smooth and cardiac. Whereas Somatic neurons control the signals to and from the skeletal system and brain.
Autonomic ganglia contains what?
Autonomic ganglia contain the cell bodies of motor neurons.
Which autonomic neurons release norepinephrine as a neurotransmitte?
Sympathetic postganglionic neurons release norepinephrine,
Which spinal region lacks autonomic preganglionic neurons?
Cervical Region
Can atomic neurons be sensory or afferent neurons?
I believe you mean autonomic neurons (part of the ANS) and yes, they can be sensory neurons. Sensory neurons are the same as afferent neurons--meaning they carry signals towards the CNS. Think as afferent as 'approaching'. Anyhow, these neurons sense the conditions of your visceral organs and whatnot. Other wise it would have no information to judge for what signals to send. So yes, autonomic neurons consist of both sensory (afferent) and motor (efferent) neurons.
What innervates involuntary effectors glands smooth or cardiac muscle?
autonomic neurons
What are the two neurotransmitters that axon terminals of autonomic neurons release?
Nonepinephrine and acetylcholine
In contrast to the somatic nervous system the autonomic nervous system?
has two motor neurons
The motor pathway of the autonomic nervous system usually involves how many neurons?
1000
Where are neurotransmitters released by neurons?
The axon terminal, into a synapse.
What does the dorsal root ganglion contain?
Autonomic ganglia contain the cell bodies of motor neurons.
Is an ankle jerk reflex somatic or autonomic?
Ankle jerk is somatic. It is the reflex action, in which the afferent. connecting and the efferent neurons are involved. Autonomic nerves do not supply the striated muscles.
