With blurred vision and eyestrain we must look at the optic nerve within the brain. From there‚ what could be causing the difficulty breathing and weakness? It must be a neurological problem involved with the synaptic centers. Since Annie is having such problems when she is working out hard and just playing around

Sensory abnormalities‚ optic neuritis‚ motor symptoms‚ organ dysfunction‚ systemic symptoms‚ etc.‚ are some aspects of the body in which may be affected by MS and are a result of debilitating transmission of an action potential from nerve cells from the brain to the spinal chord due to the demyelination of the axon (Calabresi‚ 2011). MS is an incurable disease (Boppanna‚ Huang‚ Ito & Dhib-Jalbut‚ 2011). According to Kargiotis‚ Paschali‚ Messinis and Papathanaspolous (2010)‚ treatment

The Urinary System is a group of organs in the body concerned with filtering out excess fluid and other substances from the bloodstream. The substances are filtered out from the body in the form of urine. Urine is a liquid produced by the kidneys‚ collected in the bladder and excreted through the urethra. Urine is used to extract excess minerals or vitamins as well as blood corpuscles from the body. The Urinary organs include the kidneys‚ ureters‚ bladder‚ and urethra. The Urinary system works with

Hormone-secreting organs called endocrine glands secrete hormones directly into the extracellular fluid‚ where they diffuse into the blood. The nervous and endocrine systems overlap to some extent. Certain specialized nerve cells known as neurosecretory cells release hormones into the blood. The hormones produced by these cells are sometimes called neurohormones. Chemicals such as epinephrine serve as both hormones of the endocrine system and neurotransmitters in

HOW DOES THE STRUCTURE OF NEURONES REFLECT THEIR FUNCTION The neuron or nerve cell is the structural unit of the nervous system. It is able to transmit messages between the central nervous system (CNS) and all parts of the body. There are two basic types of neuron namely - the sensory neuron (afferent) and the motor neuron (efferent) (Bear et al.‚ 3rd edition). The sensory neurons (Fig. 1-1) are capable of transmitting the sensation of pain and consist of three major portions which are the dendritic

Nervous System- Nerve Impulse When a stimulus is strong enough‚ a nerve impulse is generated in an "all or none" response which means that a stimulus strong enough to generate a nerve impulse has been given. The stimulus triggers chemical and electrical changes in the neuron. Before an impulse is received‚ a resting neuron is polarized with different charges on either side of the cell membrane. The exterior of the cell is positively charged with a larger number of sodium ions present compared
