The Peripheral Nervous System
The Peripheral Nervous System Dr. Ali Ebneshahidi Peripheral Nervous System (PNS) – Consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves. – Serves as a critical link between the body and the central nervous system. – peripheral nerves contain an outermost layer of fibrous connective tissue called epineurium which surrounds a thinner layer of fibrous connective tissue called perineurium (surrounds the bundles of nerve or fascicles). Individual nerve fibers within the nerve are surrounded by loose connective tissue called endoneurium. Cranial Nerves Cranial nerves are direct extensions of the brain. Only Nerve I (olfactory) originates from the cerebrum, the remaining 11 pairs originate from the brain stem. Nerve I (Olfactory)- for the sense of smell (sensory). Nerve II (Optic)- for the sense of vision (sensory). Nerve III (Oculomotor)- for controlling muscles and accessory structures of the eyes ( primarily motor). Nerve IV (Trochlear)- for controlling muscles of the eyes (primarily motor). Nerve V (Trigeminal)- for controlling muscles of the eyes, upper and lower jaws and tear glands (mixed). Nerve VI (Abducens)- for controlling muscles that move the eye (primarily motor). Nerve VII (Facial) – for the sense of taste and controlling facial muscles, tear glands and salivary glands (mixed). Nerve VIII (Vestibulocochlear)- for the senses of hearing and equilibrium (sensory). Nerve IX (Glossopharyngeal)- for controlling muscles in the pharynx and to control salivary glands (mixed). Nerve X (Vagus)- for controlling muscles used in speech, swallowing, and the digestive tract, and controls cardiac and smooth muscles (mixed). Nerve XI (Accessory)- for controlling muscles of soft palate, pharynx and larynx (primarily motor). Nerve XII (Hypoglossal) for controlling muscles that move the tongue ( primarily motor). -
Palm Reading
Palm Reading Also known as palmistry or chiromancy, palm reading is practiced all over the world with roots in Indian astrology and gypsy fortune-telling. The objective is to evaluate a person’s character and aspects of their life by studying the palm of their hand. There is no substantiate evidence of correlation between palm features and psychological traits; palm reading is for entertainment purposes. Getting Started Which hand to read? There are two main practices: For males, the left hand is what you’re born with, and the right is what you’ve accumulated throughout your life. For females, it’s the opposite. Your dominant hand (the hand you use most often) determines your future and your other, non-dominant hand, is used to determine the past or hidden traits Take these into consideration when choosing which hand to read. Reading the Primary Lines of your Hand 1. Interpret the Heart Line This line is believed to indicate emotional stability, romantic perspectives, depression, and cardiac health. Begins below the index finger = content with love life Begins below the middle finger = selfish when it comes to love Begins in-between the middle and index fingers = caring and understanding Is straight and short = less interest in romance Touches life line = heart is broken easily Is long and curvy = freely expresses emotions and feelings Is straight and parallel to the head line = good handle on emotions Is wavy = many relationships, absence of serious relationships Circle on the line = sad or depressed Broken line = emotional trauma 2. Examine the Head Line This line represents learning style, communication style, intellectualism, and thirst for knowledge. -
Are Astrocytes Executive Cells Within the Central Nervous System? ¿Son Los Astrocitos Células Ejecutivas Dentro Del Sistema Nervioso Central? Roberto E
DOI: 10.1590/0004-282X20160101 VIEW AND REVIEW Are astrocytes executive cells within the central nervous system? ¿Son los astrocitos células ejecutivas dentro del Sistema Nervioso Central? Roberto E. Sica1, Roberto Caccuri1, Cecilia Quarracino1, Francisco Capani1 ABSTRACT Experimental evidence suggests that astrocytes play a crucial role in the physiology of the central nervous system (CNS) by modulating synaptic activity and plasticity. Based on what is currently known we postulate that astrocytes are fundamental, along with neurons, for the information processing that takes place within the CNS. On the other hand, experimental findings and human observations signal that some of the primary degenerative diseases of the CNS, like frontotemporal dementia, Parkinson’s disease, Alzheimer’s dementia, Huntington’s dementia, primary cerebellar ataxias and amyotrophic lateral sclerosis, all of which affect the human species exclusively, may be due to astroglial dysfunction. This hypothesis is supported by observations that demonstrated that the killing of neurons by non-neural cells plays a major role in the pathogenesis of those diseases, at both their onset and their progression. Furthermore, recent findings suggest that astrocytes might be involved in the pathogenesis of some psychiatric disorders as well. Keywords: astrocytes; physiology; central nervous system; neurodegenerative diseases. RESUMEN Evidencias experimentales sugieren que los astrocitos desempeñan un rol crucial en la fisiología del sistema nervioso central (SNC) modulando la actividad y plasticidad sináptica. En base a lo actualmente conocido creemos que los astrocitos participan, en pie de igualdad con las neuronas, en los procesos de información del SNC. Además, observaciones experimentales y humanas encontraron que algunas de las enfermedades degenerativas primarias del SNC: la demencia fronto-temporal; las enfermedades de Parkinson, de Alzheimer, y de Huntington, las ataxias cerebelosas primarias y la esclerosis lateral amiotrófica, que afectan solo a los humanos, pueden deberse a astroglíopatía. -

Classification of Finger Posture in Drop Finger Due to Cervical Foraminal Stenosis: a Mini-Review
hysical M f P ed l o ic a in n r e u & o R J l e a h International Journal of Physical n a b o i t i l i a ISSN: 2329-9096t a n r t i e o t n n I Medicine & Rehabilitation Mini Review Classification of Finger Posture in Drop Finger Due to Cervical Foraminal Stenosis: A Mini-Review Mitsuru Furukawa1*, Michihiro Kamata2 1Department of Orthopedic Surgery, Murayama Medical Center, Tokyo, Japan; 2Department of Orthopedic Surgery, Keiyu Hospital, Kanagawa, Japan ABSTRACT Few reports have been published examining cervical foraminal stenosis as the cause of drop finger. This mini-review, therefore, will provide a summary of the findings of articles published on this topic, written in both English and Japanese. Cervical foraminal stenosis is difficult to diagnose from imaging findings alone; thus, physical examination findings are often needed to make a firm diagnosis. Numbness of the fingers, the extent of interscapular pain, and finger posture can be used to differentiate drop finger due to cervical foraminal stenosis from other diseases. It is crucial to provide sufficient explanation to the patient before a decompression surgery is performed because the recovery of muscle strength is often incomplete and the improvement may be small. Keywords: Drop finger; Cervical foraminal stenosis; C7 nerve root; C8 nerve root ABBREVIATIONS: RESULTS CFS: cervical foraminal stenosis; PION; Posterior Interosseous The search obtained three case reports, one clinical feature, and Nerve; ECR; Extensor Carpi Radialis; EDM; Extensor Digiti one surgical outcome from PubMed, whereas two case reports Minimi; EIP; Extensor Indicis Proprius and two reviews came from the Japan Medical Abstracts Society. -

A Touch-Cue system is a series of hand signals that are associated with consonant sounds; these hand signals are Speech Skills placed in different locations around the mouth to prompt sound production. Learning to speak is a process that develops gradually from The Touch-Cue System, presented in this book, has been adapted and modified infancy to 7 or 8 years of age. There are differences in the age at from several different sources to fit the needs of our preschool program. which children master particular speech sounds. It is important to This book was originally developed to help stimulate accurate production of error remember that learning to produce a speech sound correctly in all sounds in children with severe articulation delays, such as apraxia (motor planning words and phrases is a gradual process. It is common for children problems) and phonological processes (delayed patterns of speech). After utilizing not to produce all speech sounds correctly until age 7 or 8. the program in the classroom it became evident that it worked for more than just BY AGE: CHILDREN HAVE MASTERED THESE SOUNDS the severe children. Every child with articulation delays began to benefit from this multi-sensory approach. The book is set up to help teach parents how to use tactile, 3 ½ p, m, h, n, w, b, and vowels visual and auditory cues to stimulate accurate production of sounds. Hand signals 4 ½ k, g, d, t, ng, y are used as visual cues. -
