Medial medullary syndrome This involves the hypoglossal nucleus 2.5 mg tadalafil sale erectile dysfunction guilt in an affair, corticospinal tract and medial lemniscus generic tadalafil 5 mg overnight delivery best erectile dysfunction doctor in india. The lateral medullary syndrome is more likely to cause sensory symptoms, and the medial medullary syndrome more likely to cause motor syndromes: look again at Section 1. Since this presents as a disorder of the muscles of speech and swallowing, it is at first sight similar to a bulbar palsy, but being an upper motor neuron lesion, it is caused by a lesion on the opposite side. It is immediately above the lateral fissure, deep to the pterion, usually in the dominant hemisphere (normally the left). The main function of the glossopharyngeal nerve is the sensory supply of the oropharynx and posterior part of the tongue. Its other functions are the motor supply to stylopharyngeus; con- veying parasympathetic fibres part of the way to parotid gland and sensory supply from the carotid sinus, carotid body, and (sometimes) skin of the external acoustic meatus and tympanic membrane. Sensory fibres to pharyngeal plexus supplying mucosa of pharynx and posterior tongue. Thick line: parasympathetic fibres from inferior salivatory nucleus (ISN) to otic ganglion for parotid gland, and branchiomotor fibres to stylopharyngeus. Arterial components of the third arch form part of the common and internal carotid arteries thus explaining the carotid sinus innervation. Sensory fibres, including taste, from oropharynx, posterior tongue and carotid body chemoreceptors. The glossopharyngeal nerve (IX) 85 Branchiomotor fibres: from nucleus ambiguus to stylopharyngeus. Preganglionic axons from inferior salivatory nucleus to auricu- lotemporal nerve and otic ganglion. From variable portion of skin in external ear, axons pass in tympanic branch to main trunk of IX. Place a finger on the anterior part of the tongue (V) and then the posterior part (IX) to demonstrate this. The gag reflex is mediated by the glossopharyn- geal (afferent limb) and the vagus (efferent limb). It also transmits cutaneous sensory fibres from the pos- terior part of the external auditory meatus and the tympanic membrane. It supplies the gut tube as far as the splenic flexure of the trans- verse colon (roughly), and the heart, tracheobronchial tree and abdominal viscera. These fibres, though, are by no means essential to life, whatever others may tell you, since they can be cut, as in vagotomy. And do you suppose heart surgeons reconnect vagal branches during transplant operations? Its name reflects both its wide distribution and the type of sensation it conveys (Latin: vagus – vague, indefinite, wandering). In and below foramen are two sensory ganglia: jugular and nodose, containing cell bodies of sensory fibres. Auricular branch passes through canal in temporal bone and conveys sensory fibres from external acoustic meatus and tympanic membrane. The vagus nerve (X) 87 Nucleus of solitary tract From skin of EAM and tympanic membrane Sensory from pharynx and upper larynx Nucleus ambiguus (branchiomotor) Motor to pharynx Dorsal motor nucleus (parasympathetic) Sensory and branchiomotor fibres in recurrent laryngeal nerves X continuing to thorax Subclavian artery (right side), and abdomen ligamentum arteriosum (left side) Fig. Gives pharyngeal branches, and superior laryngeal nerve which has internal (sensory above vocal cords) and external (cricothyroid) branches. Both ascend between trachea and oesophagus to laryngeal muscles (not cricothyroid) and sensation of larynx below vocal cords, trachea, oesophagus. Enters abdomen through oesophageal hiatus in diaphragm as anterior and posterior trunks and 88 Glossopharyngeal, vagus and accessory nerves contributes fibres to abdominal viscera and to coeliac, superior mesenteric and myenteric plexuses. Branches pass in lesser omen- tum alongside lesser curvature of stomach to innervate pyloric antrum (nerves of Latarjet), and to give hepatic branches. Structures derived from these include the pharyngeal and laryngeal cartilages and muscles. The sixth arch artery on the left gives rise to the ductus arteriosus (ligamentum after birth) around which the left sixth arch nerve, the recurrent laryngeal, is caught when the artery descends. The sixth arch artery on the right degen- erates, so the right recurrent laryngeal nerve is related to the most caudal persisting branchial arch artery, the fourth, which becomes the right subclavian. The motor function of the vagus in the neck is branchiomotor (special visceral motor): motor function in the thorax and abdomen is parasympathetic (general visceral motor). Dorsal motor nucleus of vagus (DMNX) in medulla gives pregan- glionic axons to innervate heart and thoracoabdominal viscera (foregut and midgut). Cell bodies of postganglionic neurons are generally in wall of destination organ, for example cardiac, myen- teric plexuses. The vagus nerve (X) 89 Somatic sensory fibres: to sensory nuclei of the trigeminal nerve From posterior wall of external auditory meatus and posterior por- tion of external surface of tympanic membrane, fibres pass in auricular branch of X to main trunk in jugular foramen. Taste fibres from epiglottic area, visceral sensory fibres from hypopharynx, larynx, oesophagus, trachea, thoracoabdominal vis- cera and aortic baro- and chemo-receptors. This develops from heart tubes formed by angiogenetic cells initially found in the wall of the yolk sac, from which the gut tube develops.

CHAPTER 13 With a Little Help from My Family and Friends A faithful friend is the medicine of life. In this chapter, I want to encourage you to pursue an active social life, not only by maintaining the rela- tionships you have developed over the years, but by continuing to forge new relationships—with relatives with whom you have lost contact and with aquaintances you meet who share your interests. Many people with Parkinson’s retire from a busy career only to discover that their need to interact with others, which had pre- viously been satisfied by their spouses, children, and coworkers, is now met by only a few close family members. In some cases, the spouse, too, has passed away; in others, the children live at some distance. Unhappiness is intensified when one or two individu- als alone bear the entire responsibility of meeting the social and emotional needs of the person with Parkinson’s and that responsi- bility becomes too much for them. Even if your family has been torn apart by grudges or misunder- standings, don’t be afraid to make the first move. Love and accept your family members as they are, and you will enjoy their love and acceptance. Regardless of how small or large, your family and your spouse’s family are important parts of your emotional sup- port network. But my sisters, Doris and Donna, and my sister-in-law, Linda, are also very special friends. Whether we sisters are giggling like children, shopping the sales, just quietly talking, or even having an argument, we know that we can turn to one another with our serious problems. The first real tragedy that we shared was the death of Donna’s fifteen-month-old child when she was struck by a car. Although they live at some distance, they have been very helpful, even coming down to help me with housecleaning. They never fail to invite me to join them in activities or outings at appropriate times. Whenever 154 living well with parkinson’s he and his wife, Linda, came to Bangor, they appeared on our doorstep, asking us to eat out with them. Whenever we go to those same restaurants now, we can’t help remembering our meals and the good times with George and Linda. His death has left a great void in my life, as did my father’s death earlier, but I still feel Dad’s and George’s love for me as I call on the memory of their wisdom, humor, and words of comfort. A special bond with him was formed when I lived with Doris and her family (while Blaine was away in the service), and I spent a great deal of time with my infant nephew. Recently, I wrote a letter to him explaining the bond I felt, which he understood and said that he felt, too. When they were young, Donna brought them to visit for four or five days at a time, and we enjoyed many things together, espe- cially crafts, picnics, excursions, and games. We couldn’t afford expensive gifts in those days, but I made and assembled very decorative gift boxes, which my nieces looked for- ward to every year. All of Donna’s girls became interested in crafts, an interest they attribute to those early craft sessions, and they now come down to visit with their own children. When you are reestablishing old ties, remember that relation- ships take time to develop. For example, when my sisters and I went off to school and later married, we couldn’t afford many long-distance telephone calls, but we wrote long letters to keep one another up-to-date on our lives, and we visited often. Main- tain your correspondence with your relatives, telephone them, visit and invite them to visit you, go on excursions and eat out with a little help from my family and friends 155 together, celebrate birthdays and holidays together. Be interested in their activities and successes, and be supportive in their times of trouble or discouragement. In addition to relatives, you need to include many friends in your support network. There were the neighbors, Dana and Mary, and Marge and Ervin, whose lives meshed with ours when our children became so close that it was hard to tell which were theirs and which were ours. Whenever we need to get away, we drive down to New Hampshire or Connecticut to spend a weekend with one couple or the other. Every few days she calls to say that she is going out, and I am welcome to come along. She is the kind of friend who will rearrange her schedule, if she can, to help me. We found new friends in our church in Hampden and others through Blaine’s work, even before he started teaching. Be very deliberate about keeping in touch with your old friends, and make time to see them each week or as often as possible.
