Nerve

consists of the brain and the spinal cord, whereas, the PNS consists of nerves outside the brain and spinal cord. The PNS connects the rest of the body to the CNS. The PNS are grouped into two categories, sensory (afferent) nerves and motor (efferent) nerves. Sensory nerves convey information from receptors to the CNS. Motor nerves convey information from the CNS to the muscles and the rest of the body. The motor (efferent) nerves are further divided into two; somatic system (voluntary control)…

into Central Nervous System (CNS) and Peripheral Nervous System (PNS). Central nervous system controls all important nerves inside the body enable the body to do its daily tasks. Peripheral nervous system is the system that control on the outside the brain and spinal cord. Both systems are requiring in the body for different functions. The central nervous system consists of the nerves in brain and spinal cord. The brain is responsible for organize and coordinate the information. Consciously and…

This disease is a result of of damage to your nerves which causes pain, numbness and weakness of hands feet, etc. these nerves send signals to your brain and information. Every nerve in your peripheral system has a specific function, so symptoms depend on the type of nerves affected. Signs/ factors: • Gradual onset of numbness and tingling in your hands and feet, which may spread upwards into your legs and arms • Sharp jabbing • Extreme sensitivity to touch • Lack of coordination and falling •…

A distal transhumeral amputation typically occurs above the elbow. Cheesborough et al. suggest preserving the humerus bone segment at an approximate length of 6 to 8 cm. In addition to the length they recommend fixating the humerus at a 70 degree angle with a metal plate to give the arm rotational and leverage control when using a prosthetic arm (Cheesborough et al.,2015). In addition the shape and length of the residual humerus bone allows for increased suspension of a prosthetic arm (Tintle…

arm from T1-T4. What nerves are responsible for sensation in this path? Answers: A. Medial Brachial Cutaneous and Lateral Antebrachial Cutaneous B. Intercostalbrachial and Axillary C. Medial Brachial Cutaneous and Intercostalbrachial D. Supraclavicular and Axillary E. Lateral antebrachial cutaneous and Radial Rationale for each answer: Answer: C. Medial Brachial Cutaneous and Intercostalbrachial Myocardial Infarction pain is thought to originate when visceral sensory nerve endings in the…

My eighty-four-year-old neighbor, Colette, has come to me to talk about how she is having eye complications after a recent fall to the head. After reviewing the symptoms, I think Colette has damaged her oculomotor nerve, cranial nerve IV. Furthermore, the inferior rectus is in charge of depressing, adducting, and laterally rotating the eye (Schuenke, Schulte, & Schumacher 2016). Similarly, the inferior rectus muscle positions the eye infraversion, dextrodepression, levodepression,…

signs of neurologic changes. The cranial nerve assessment includes assessing cranial nerve from 1 through X11, which have sensory, motor either somatic or parasympathetic, or have a mixed function. Olfactory Nerve (CN I)- the olfactory nerve serves the sense of olfaction or smell, Test is done with the use of non-noxious aromatic substances and check if able to smell and identify and mark if any abnormality noted. Optic Nerve (CN II): This is a purely sensory nerve, test each eye for visual…

1.0 Neural Tissue Engineering Nerve injury and loss are common clinical problems, that can cause significant affects to a patient’s overall quality of life: Whether within the Peripheral or Central Nervous Systems. Neural Engineering is a sub-discipline within Biomedical Engineering that utilizes engineering techniques to understand, repair, replace and even enhance the properties of the neural system. In the field of Neural Tissue Engineering, the practice has been greatly limited to the…

neurogenic bladder stands for a lack of bladder control due to a dysfunction of nerves affecting afferent or efferent signaling. These nerves carry messages between the bladder and spinal cord, and direct the holding and release of urine. When the nerves fail to function, the symptoms of neurogenic bladder develop, which is the condition that affects millions of people around the world. Function of the bladder Several nerve mechanisms regulate urine storage and bladder emptying. As urine fills…

coordination of the lips and palate. This indicates that Susan is likely experiencing mixed spastic-ataxic dysarthria due to lesions on the upper motor neurone pathway (Wilkinson and Lennox 2005) in the corticobulbar tract which innervates the cranial nerves and the cerebellum (Bethoux et al 2013). Lesions on the upper motor neurone pathway/ corticobulbar tract would typically cause the spastic symptoms that the client is showing e.g. slower rate of speech, increased muscle tone and imprecise…
