Nerve

There are four main tissue types in a human’s body which are connective, epithelial, muscular, and nerve tissue. Connective tissue has the largest amount amongst the tissue types and the most distributed of the tissues. Epithelial tissue covers the body surface and forms the lining for most internal cavities. The skin is an organ made up of epithelial tissue which protects the body from dirt, dust, bacteria and other microbes that may be harmful (“Exploring Four Types of Tissues,” 2016). There are

Erb’s Palsy Amanda Metrikin 5/11/16 Pediatrics Erb’s palsy is a form of brachial plexus palsy. Brachial plexus palsy occurs when nerves in the brachial plexus get damaged and signals cannot travel in their normal pattern from the brain to the arm muscles. This causes paralysis (palsy) or weakness in the arm (brachial) region, as well as atrophy of the deltoid, biceps, and brachialis muscles. About two out of every 1,000 babies have this condition and it often occurs during

Nerve Functions The glossopharyngeal nerve is the ninth (IX) cranial nerve. It is an ipsilateral mixed nerve, meaning it has both sensory and motor components. Sensory: Conveys sensations from posterior third of the tongue and the outer ear such as taste (specifically bitter and sour tastes), pressure, pain, and temperature. This nerve also plays a role in regulating blood pressure and respiration. Motor: The motor portion of this nerve initiates reflexes such as swallowing and gagging, as well

cord (Albright, A.L., 1995). James’ excess production of excitatory impulses originates in the golgi tendons of organs and muscle spindle, a specialised sensory receptor in the muscle (Albright, A.L., 1995). The impulse then passes through afferent nerves into the spinal cord and releases excitatory neurotransmitters. In contrast, the lack of ability to generate inhibitory impulses suggest that the regions of the brain responsible for the generation of inhibitory impulses including the basal ganglia

States have LEMS. This disease is an autoimmune disease in which the immune system attacks the body’s own healthy tissues. The immune system attacks neuromuscular junctions, which are the areas where a person’s nerves and muscles connects. This then affects the way muscles and nerves communicate and make it difficult to move muscles. LEMS

lack in connection between the nerves and muscles. The two parts of the brain affected by spastic cerebral palsy are the cerebral motor cortex and the white matter. The cerebral motor cortex is responsible for movement, hearing, speech, thinking, visual processing etc. Therefore if the cerebral motor cortex is damaged then all those previously listed may be affected. White matter is responsible for transmitting signals to the body, consequently if it is damaged, nerve signals are interrupted. (Common

chloride. When in combination with adrenaline it also contains sodium metabisulphite. Preparations with fentanyl contain fentanyl citrate (AstraZeneca Ltd., 2015). Indications Bupivacaine hydrochloride is indicated for local anaesthesia; this includes nerve block, infiltration, epidural (with fentanyl) and intrathecal (spinal) anaesthesia and analgesia (MIMS, 2013). Generally a single-shot injection is administered, however, to achieve prolonged anaesthesia and post-operative analgesia, the drug can be

So far, I have told you the good news, the bad news is that his arm will probably never gain the same movement it once had. The nerves in his arm can never be attached the same as they were before once they have been severed the way your sons have been. This unfortunately means he might have a little bit of trouble from this arm throughout his lifetime. The movement in his arm, forearm

formation and reformation of these cross bridges is what is known as cross bridge cycling and is what is responsible for repeated muscle contraction in the same sarcomere. Muscle contractions only occur when they receive action potentials from nerve cells called motor neurons. These motor neurons synapse directly onto muscle cells- sometimes even innervating multiple muscle cells. If there is a need for stronger contraction, motor neurons can be recruited to aid in the increase of muscle contraction

is formed by various interconnected networks, called plexuses, of enteric neurons, glial cells, and axons (Widmaier et al. 2014). The majority of these nerve cells are found within two different arrangements of ganglia (Fig. 1): the myenteric (Auerbach’s) plexus and the submucosal (Meissner’s) plexus (Furness 2006; Guyton and Hall 2006). The nerve cells’ axons either synapse with additional neurons in the plexus or innervate the smooth muscle of digestive organs (Furness 2006). Neural activity in
