Ulnar nerve

Clinical signs are caused by damage to the grey matter and white matter of the spinal cord. Pain, temperature, vibration, proprioception and dermatomal sensations all may be diminished, which will depend on the exact area of the cord or nerve-root which is compromised. Patients may also complain urinary urgency, hesitation and frequency but infrequnetly of urinary incontinence and retention. Fecal incontinence is very rearly present. Decreased tendon reflexes (hyporeflexia), muscle weakness and…

Where is David? Common Cycling Injuries Are there common cycling injuries? "My right knee just started hurting about 4 days ago. I am having sharp pains on the lateral side of my knee. I had to bike the last couple days with just my left leg, which (wasn't a good thing)! Hopefully it will be better tomorrow!" David Shirley, taking a few days off in Portland, Oregon. Asking the question implies the answer; of course cycling has its list of common injuries, which are amplified when a cyclist…

Symptoms including weakness and wasting of hand muscles, and numbness in the hand. Disputed TOS is caused by injury to the nerves in the brachial plexus. The most prominent symptom of the disorder is pain and other symptoms include weakness and fatigue. Venous is generally rare that affects men and women equally. The cause of this type of TOS remains unknown but often develops…

from plastic and usually have small sensors to track electrical nerves within a limb, but with developed technology, prosthetics can do so much more. Prosthetics have developed to detect certain signals, and in order to prepare an individual for prosthetics, stimulations are used. Stimulation signals get sent to the three major nerves that usually carry sensory signals from the hand to the brain: the median, ulnar, and radial nerves. This stimulation is composed of balanced current flows in…

and medical treatment for patients. "Medical specialists are doctors who have completed advanced education and clinical training in a specific area of medicine (their specialty area) (Webmdcom, 2015)." For example: "A patient suffering from ulnar nerve compression in the right arm will receive treatment from a Neurologist; a doctor who specializes in the diagnosis and treatment of the brain, spinal cord, nervous system diseases, such as multiple sclerosis, Alzheimer's disease, headaches,…

The anatomy of the human body is constantly being studied and new information on ourselves will continue to be revealed as we research more and more. There are many structures and systems in the human body that allow us to function, the human foot and hand for example. The hand and foot are a symbol for the ability to work for many people. Without these structures on the human body, the human race would not have had the ability to be where it is today. But what makes up the hand and foot,…

system(PNS) consists of all cranial, and spinal nerves in the body. The nervous system and especially the brain, are the most complex organs in humans. The brain allows cognitive thought, control of skeletal muscles, and it controls a myriad of other involuntary actions inside the body (from making the heart beat, regulating internal heat/ph/sugar levels, to digestion, sleeping, and many more functions required for life). The spinal cord, and all the body’s nerves transmit: sensory…

the middle third of humerus ,embracing the deltoid insertion. In addition it also had attachement to the adjoining part of the lateral intermuscular septum. Its fibers ran vertically and terminated in a thick tendon to be inserted onto the ulnar tuberosity. Fibers of the deep head could be seen arising from the anterormedial and anterorlateral suaface of the distal third of the humerus. In addition fibers were seen to be attached to the medial and lateral intermuscular…

tingling, depression, excessive thirst, heat/cold intolerance, frequent urination and urinary urgency. On examination of the wrist, range of motion is restricted with palmar flexion, dorsiflexion, ulnar deviation, radial deviation, supination and pronation. Movements are painful with dorsiflexion, ulnar deviation, radial deviation, supination and pronation. There is tenderness to palpation noted over the anatomical snuffbox, scapholunate articulation and triangular fibrocartilage complex. There…

In this experiment, we investigated electrically stimulated nerves n the forearm to display recruitment, summation, tetanus and conduction velocity of action potentials. Muscle are either directly joined to the bone or connected by tendons, which by definition are resilient bundles of collagen fibers. Motor nerves innervate the fibers of the skeletal muscles, which is controlled voluntarily. The action potential in a muscle fiber allows for an increase in the influx of calcium causing what we…
