Yes,they can be found that is the first order neurons .Hence leisions in the lateral medulla produce Horners syndrome.
The pupil is innervated by sympathetic and parasympathetic fibers. Pupillary dilation is mediated by a three- neuron sympathetic pathway that originates in the hypothalamus.
The first order (central) neuron descends caudally from the hypothalamus to the first synapse in the cervical spinal cord (C8-T2 level-also called the ciliospinal center of Budge). The descending sympathetic tract is in close proximity to other tracts and nuclei in the brainstem.
The second order (preganglionic) neuron destined for the head and neck exits the spinal cord and travels in the cervical sympathetic chain through the brachial plexus, over the pulmonary apex and synapses in the superior cervical ganglion. The superior cervical ganglion is located near the angle of the mandible and the bifurcation of the common carotid artery.
The third order (postganglionic) neuron for the orbit enters the cranium within the adventitia of the internal carotid artery into the cavernous sinus. Here the oculosympathetic fibers exit the internal carotid artery in close proximity to the trigeminal ganglion and the sixth cranial nerve and join the 1st division of the trigeminal nerve to enter the orbit. The fibers (long ciliary nerve) innervate the dilator muscles of the iris and the Müller's muscle in the upper and lower lid.
The vasomotor and sudomotor fibers to the face exit the superior cervical ganglion and ascend in the external carotid artery.
Pupillary constriction is produced by parasympathetic (cholinergic) fibers that travel with the third cranial (oculomotor) nerve
What else can I help you with?
Is epinephrine converted to nor epinephrine in the sympathetic system?
Yes, epinephrine is converted to norepinephrine in the sympathetic nervous system by the enzyme phenylethanolamine N-methyltransferase (PNMT), which is found in the adrenal medulla. Norepinephrine acts as a neurotransmitter in the sympathetic nervous system.
Where is the cardiac regulatory center found?
medulla oblongata
What body cavity is the ascending aorta found?
Ascending aorta, arch of aorta and the descending aorta are located in your thoracic cavity.
What structure is part of the brainstem?
The main parts of the brain stem are the medulla oblongata (myelencephalon), pons (part of metencephalon), and midbrain (mesencephalon). There are also many other structures such as various nuclei and neuronal pathways.
Which quadrant is the abdomen is the descending colon located?
The descending colon is primarily located in the left lower quadrant of the abdomen. It extends downward from the transverse colon and continues into the sigmoid colon. In some cases, a portion of the descending colon may also be found in the left upper quadrant, depending on individual anatomy.
Is epinephrine converted to nor epinephrine in the sympathetic system?
Yes, epinephrine is converted to norepinephrine in the sympathetic nervous system by the enzyme phenylethanolamine N-methyltransferase (PNMT), which is found in the adrenal medulla. Norepinephrine acts as a neurotransmitter in the sympathetic nervous system.
What parts of the nephron is found in the renal medulla?
Most nephrons (85%) are contained withing the renal cortex. The remaining 15% are called juxtamedullary nephrons and their glomeruli are close to the corticomedullary border. Their loops of Henle are found within the renal medulla.
Are the glomerulus the glomerular capsule and the proximal convoluted tubule all located within the medulla region of the kidney?
Renal Papilla are found in the medulla, but the glomerulus is found in the renal cortex.
Is the medulla found in African American hair?
no it is not.
Is the respiratory center a group of neurons in the thalamus?
The control center of the respiratory are found in the medulla and pons. Medulla or medulla oblongata and pons are part of the brainstem.
Where is the cardiac regulatory center found?
medulla oblongata
What part of the renal tubules can be found in the medulla of the kidney?
The renal medulla is the innermost part of the kidney. The renal medulla is split up into a number of sections, known as the renal pyramids
Where is cerebellum found?
the cerebellum is found at the back of the head, that means it is above the medulla.
Is one of the functional centers found within the medulla oblongata?
True
What is indirect evangelism?
Leaving tracts and religious pamphlets where they may be found and read.
Nephrons renal cortex renal medulla and Bowman's capsule are found where?
in the kidneys
Where could a support group for those with reflex sympathetic dystrophy be found?
"To find a support group for those with reflex sympathetic dystrophy, you can try the Reflex Sympathetic Dystrophy Syndrome Association, where they can help you fully."
