well as adds curvature to the spine. Occasionally tumors develop on the brain or spinal cord. Half of the people with NF1 also inhibit learning disabilities. The less common disorder‚ NF2‚ characterizes itself by multiple tumors on cranial and spinal nerves. Hearing loss will nearly inevitably occur in the early teens for people with NF2. Genetic Cause [pic] Most commonly Neurofibromatosis is passed on by family members through genes. However‚ 30 to 50% of newly diagnosed people have no family

• Diagnosed HIV Stage 4 on treatment (LTE) • CMV retinitis • Central facial palsy (flattening of R nasolabial fold) - paresis of the lower half of one side of the face - damage to upper motor neurons of the facial nerve. - The facial motor nucleus has dorsal and ventral divisions that contain lower motor neurons supplying the muscles of the upper and lower face‚ respectively. The dorsal division receives bilateral upper motor neuron input (i.e. from both sides

identify neurologic changes by performing a bedside assessment. A proper bedside assessment includes: vital signs‚ pupillary responses‚ posturing response‚ hand grasp‚ muscle strength and symmetry‚ sensory evaluation‚ and an evaluation of the cranial nerves (Crimlisk & Grande‚ 2004). A registered nurse may also be asked to help a physician perform neurologic tests. These include superficial cutaneous reflexes‚ deep tendon reflexes‚ and vestibular reflexes (Crimlisk & Grande‚ 2004). Superficial

1. White matter is found on the outside or surface of the cord. It connects the cord and the brain and is made up of nerve fibres. White matter contains motor fibres which run down from the motor centre of the brain‚ the cerebrum and the cerebellum to the motor cells of the cord Sensory fibres also run up the cord from the sensory cells of the cord to the sensory centre of the brain. 2.

neighbor I would say it is very likely that she has damaged her oculomotor nerve. The oculomotor nerve innervates both the inferior rectus muscle and the levator palpebrae superioris. The inferior rectus muscle allows the eye to depress and abduct‚ if there were an injury to the oculomotor nerve it could cause the eye to retain this position. The levator palpebrae superioris allows the eyelid to elevate and damage to the nerve here would cause the inability to fully lift her right eyelid (Drake‚ Richard

use of Nerve agents‚ and to a larger extent Chemical Weapons‚ is illegal according to United Nations Resolution 687 which passed in 1991. The production‚ stockpiling‚ and use of these weapons were banned by The Hague Convention of 1899 and the Geneva Protocol of 1925. All Nerve agents are fatal to the human body in the same way. Some are more potent‚ and some remain on the battlefield longer than others. Many factors play a role in how long a Nerve agent remains on the battlefield. Nerve agents come

Sciatic Nerve pain in your lower back that sometimes radiates down your leg and you find it impossible to sit down comfortably? Relief is on the way! The Sciatic Nerve is actually three nerve endings that exit the base of your spinal column‚ then travel across your buttocks and down the backs of your legs. Along this path your Sciatic Nerve passes through several thick muscles. When these thick muscles‚ like your Hamstrings or Piriformis Muscle tighten up‚ they can swell and press on the nerve which
