As part of which nervous system do postganglionic neurons release norepinephrine?
Sympathetic nervous system, which is part of autonomic nervous system.
A knee-jerk reflex employs motor neurons and what?
it employs sensory and motor neurons
What is a specialized cell that conducts impulses through the nervous system?
Neurons transmit and receive signals in the nervous system
Sensory neurons and motor neurons are connected by?
Interneurons
Nervous tissue is composed of cells called?
neurons
Which autonomic neurons release norepinephrine as a neurotransmitte?
Sympathetic postganglionic neurons release norepinephrine,
Where do sympathetic fibers originate?
The sympathetic motor neurons come from the thoracic through the lumbar region of the spinal cord.
When a preganglionic neuron innervates several postganglionic neurons it is called what?
divergence
Is acetylcholine the substance released by the axon terminals of both somatic motor neurons and postganglionic parasympathetic neurons?
True
Which organ consists of modified postganglionic neurons without dendrities or axons?
Adrenal Glands
Does the gray rami communicans contain fibers of a preganglionic or postganglionic neurons?
could be preganglionic
Which neurons are classified as an adrenergic fiber?
The neuron classified as an adrenergic fiber is the sympathetic postganglionic neuron.
What are the differences between preganglionic and postganglionic neurons?
You have a really good question. Studying the nervous system can be overwhelming and quit confusing. Preganglionic Neurons come from the CNS to the Ganglion ( mass of neuron cell bodies and dendrites) and Postganglionic neurons leave the ganglion and head toward the effector organ ( smooth muscle, glands, etc..).
Which nervous system subdivision is a chain of two motor neurons consisting of a preganglionic and a postganglionic neuron?
autonomic
As part of which nervous system do postganglionic neurons release norepinephrine?
Sympathetic nervous system, which is part of autonomic nervous system.
Where are post ganglionic neurons cell bodies located?
Postganglionic neuron cell body lies outside the CNS in an autonomic ganglion
Where do neurons originate from?
endocrine system
