diabetic neuropathy could be ruled out since the patient is negative for diabetes per the Hgb A1C. Likewise‚ cervical radiculopathy could be ruled out since the patient is not undergoing any neck pain or stiffness and the MRI was negative for any pinched nerve to the C-spine. Medial Epicondylitis can be ruled out since the patient is not undergoing pain in the elbow. This condition witnessed in golfers‚ which the patient do not perform or play. Hematoma of the volar wrist could likewise be ruled out since

Definition The median nerve‚ which controls movement and feeling in the palm-side of the hand‚ runs from the forearm to the hand through the carpal tunnel in the wrist. The bottom and sides of this tunnel are formed by bones‚ and the top of the tunnel is covered by strong band of connective tissue called a ligament. Repetetive movement‚ or certain conditions such as pregnancy and arthritis‚ can cause swelling within the carpal tunnel. The swelling puts pressure on the median nerve and can cause numbness

increased action of the reflexes.1 Hyperflexia (exaggerated response) results from damaged or diseased motor areas in the CNS.2Hypoflexia is defined as a diminished function of the reflexes. Hypoflexia (inhibited response) results from degeneration of nerve pathways‚ voluntary motor control‚ and other factors.2 1.

The most common type of glaucoma is the open-angle type. Open-angle glaucoma (also known as primary open-angle and wide-angle glaucoma) is a type where there is fluid blockage in the eye and pressure builds up in the eye causing damage to the optic nerve. Closed-angle glaucoma is a much more serious situation. Closed angle occurs when fluid is blocked from draining out of the eye causing pressure to build in the front of the eye. This can be extremely painful and requires immediate medical treatment

head and the skin was reflected. The skull was nibbled avoiding damage to the brain. The brain was removed by releasing it gently from all its attachments from below and sides. Trigeminal ganglia were separated by cutting at the junction where the nerve enters into the brain stem. The brain was cleaned and washed with tap water followed by sterile water to remove excessive fixative materials. Olfactory bulbs were separated from the brain along with a small portion of the frontal pole. Cerebrum and

Session 9: The Nervous System - Assignment #2 PhysioEx Assignment : Exercise 3 Neurophysiology of Nerve Impulses Activity 1: The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Increasing the extracellular K+ causes the membrane potential to change to a less negative value because when K+ ions diffuse out across the membrane they are leaving behind a net negative charge. 2. Explain

Over the next decade‚ the most vibrant Wireless Power Transmission (WPT) markets will involve the contactless charging of portable and mobile equipment‚ in particular consumer electronics and electric vehicles. Today‚ development teams worldwide are stretching the boundaries of physics using available components to create systems that are able to compete with the efficiencies of wired solutions while offering the conveniences of wire free connections.

a simple nerve circuit. A stimulus‚ such as a light tap with a rubber hammer‚ causes sensory neurons (nerve cells) to send signals to the spinal cord. There‚ the signals are conveyed both to the brainand to nerves that control muscles affected by the stimulus. Without any brain intervention‚ these muscles may respond to an appropriate stimulus by contracting. Reflex tests measure the presence and strength of a number ofreflexes. In so doing‚ they help to assess the integrity of the nerve circuits
