Where are specialized second order neurons of the sympathetic nervous system that release neurotransmitters into the bloodstream located?
In the adrenal glands
Where do second-order neurons synapse with third-order neurons?
ventral posterolateral nucleus of the thalamusthalamusin the thalamus
First order sensory neurons?
First order sensory neurons begin in the receptor, travel to dorsal/posterior gray horn of the spinal cord where they synapse with the second order sensory neurons.
What is third order neuron?
A second order neuron is the 2nd neuron to carry an order. The order could be a sensory stimulus or a motor stimulus. For e.g. in order to move a muscle, the order for that muscle to contract starts at the cerebral cortex in the somatomotor area. That is the first order neuron. The axon of the 1st order neuron will synapse with the 2nd order neuron at the level of the brain stem, which commonly decussate (crosses over) to the opposite side. In turn, the axon of the 2nd order neuron will descend along the spinal cord tracts where it will synapse with the 3rd order neuron. The 3rd order neuron is located in the ventral horn of the spinal cord, which will exit with the spinal nerve to supply the muscle.
What is the location for sensory neurons?
They can be found in the dorsal root ganglia, retina, peripheral vestibular organs, cochlea, and enteric nervous system. Then there are second order sensory neurons in the brain that form the basis of the 'sensory homonculus'.
Second order neurons of both specific and nonspecific ascending pathways terminate where?
Thalamus.
What is the medical term meaning chemicals released by neurons that stimulate other neurons muscles or glands?
A neurotransmitter is released by neurons in order to signal other neurons, muscles, or glands.neurotransmittersneurotransmitters
What is neurons associated with sensory receptor?
third order neuron
Do Second-order neurons of ascending sensory pathways always decussate.?
No! Only neurons of the specific (lemniscal) & non-specific (anterolateral) pathways decussate and sensation is therfore interpreted in the opposite cerebral hemisphere.Spinocerebellar ascending pathways transmit proprioceptive sensory stimuli to the same side of the cerebellum.
Did any ancient civilizations develop myths about tornadoes in order to explain how or why they occur?
They looked like neurons.
What testament is Mark in?
The Gospel of Mark is located in the New Testament. It is the second Gospel; in order they go Matthew, Mark, Luke and John.
Is a second order consumer a carnivore?
Second-order consumers feed on first-order consumers. An eagle is an example of a second-order consumer. Examples of first-order consumers are rabbits and mice.
