What else can I help you with?
Is Autonomic ganglia are motor ganglia only?
No, autonomic ganglia can contain both motor and sensory neurons. Motor neurons in autonomic ganglia innervate smooth muscle, cardiac muscle, and glands, while sensory neurons can detect stimuli within the autonomic nervous system.
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?
The thoracic region of the spinal cord lacks autonomic preganglionic neurons. Autonomic preganglionic neurons are found in the intermediolateral cell columns of the spinal cord at the thoracolumbar (T1-L2) and sacral (S2-S4) levels.
What are the two neurotransmitters that axon terminals of autonomic neurons release?
The two main neurotransmitters released by the axon terminals of autonomic neurons are acetylcholine and norepinephrine. Acetylcholine is predominantly released by parasympathetic neurons, while norepinephrine is released by sympathetic neurons.
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.
In a neuron where are voltage-gated calcium channels located?
Voltage-gated calcium channels in neurons are mainly located in the axon terminals, where they play a key role in mediating calcium entry upon depolarization. This influx of calcium triggers neurotransmitter release at the synapse, allowing for communication between neurons.
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
As part of which nervous system do postganglionic neurons release norepinephrine?
Sympathetic nervous system, which is part of autonomic nervous system.
Voltage regulated channels can be found where?
Voltage-regulated channels can be found in excitable cells, such as neurons and muscle cells, where they help regulate the flow of ions across the cell membrane in response to changes in membrane potential. These channels play a crucial role in processes like action potentials in neurons and muscle contraction.
