Which division of the autonomic nervous system is characterized by short preganglionic and long postganglionic fibers?
The parasympathetic nervous system has long preganglionic and short postganglionic fibers
How do preganglionic fibers run?
Preganglionic fibers of the autonomic nervous system typically run from the central nervous system to an autonomic ganglion outside the central nervous system, where they synapse with postganglionic neurons. These fibers are part of the efferent pathway that transmits signals from the central nervous system to the peripheral organs and tissues.
Where do Preganglionic neurons develop from?
Preganglionic neurons develop from the neural tube during embryonic development. They are part of the autonomic nervous system and transmit signals from the central nervous system to the autonomic ganglia, where they synapse with postganglionic neurons.
What is the first motor neuron in an autonomic pathway called?
The first motor neuron in an autonomic pathway is called a preganglionic neuron. It originates in the central nervous system and synapses with a postganglionic neuron in an autonomic ganglion.
Which nervous system subdivision is a chain of two motor neurons consisting of a preganglionic and a postganglionic neuron?
autonomic
What is a preganglionic neuron?
A preganglionic neuron is a type of neuron located in the central nervous system that forms synapses with ganglionic neurons in the autonomic nervous system. It carries signals from the central nervous system to the ganglia, allowing for communication between the brain and the autonomic nervous system.
The motor pathway of the autonomic nervous system usually involves how many neurons?
The motor pathway of the autonomic nervous system typically involves two neurons: a preganglionic neuron that originates in the central nervous system and a postganglionic neuron that extends to the target tissue or organ.
What nerve do the preganglionic fibers travel through?
The preganglionic fibers of the autonomic nervous system travel through the cranial nerves (in the head) and the spinal nerves (in the rest of the body). They synapse with postganglionic neurons in autonomic ganglia before reaching their target organs.
What nervous system innervates cardiac and smooth muscles and glands?
They are controlled by the autonomous nervous system.== ==
What kind of Eye muscles are controlled by the autonomic nervous system?
intrinsic eye muscles are controlled by the autonomic nervous system
As part of which nervous system do postganglionic neurons release norepinephrine?
The postganglionic neurons release norepinephrine as part of the sympathetic nervous system. These neurons are part of the autonomic nervous system that controls the body's fight-or-flight response.
What describes the parasympathetic division of the autonomic nervous system?
The autonomic nervous system.
