Neuromuscular blocking drugs were first used by South American Indians on their arrows to paralyze their prey. During that time neuromuscular drugs were called curare. They were first written about in a letter by a chronicler‚ employed by the Court of King Ferdinand and Queen Isabella‚ in 1516. In the 18th century Edward Bancroft‚ a physician‚ brought samples of curare back from South America and Sir Benjamin Brodie showed how small animals could be left alive after being injected with curare and

The sensory process begins as the ear senses the crack of the bat as it strikes the ball. The information received by the ear is received by the temporal lobe which alerts that an action has taken place which begins the transmission of neural messaging. Next‚ a dendrite at the receiving end of neuron cell will take the initial transmission and carry it forward to the body of the cell. Once the dendrite has received enough information the process will continue by undergoing a nerve impulse sending

Neuro- is nerves and transmitter can send waves that carry a signal. In other words‚ a neurotransmitter is sort of like a mail man‚ although in this case instead of being called a mail man‚ it is called a chemical messenger. Like a mail man‚ a chemical messenger can transmit signals or codes from one neuron to another. And the way that this takes place is by synapses. There are two synapses that have two different names that are allowing these neurons to communicate or send messages to one another

I.Abstract Guillain-Barre Syndrome (GBS) is an auto-immune disease that is rare but can lead to paralysis of limbs and the diaphragm. Ventilatory failure is commonly seen in patients with progressing diseases. The causes of GBS syndrome is unknown‚ however a few culprits are being studied. The most common explanation for GBS is the demyelination of the peripheral nervous system. Other causes in question include flu vaccinations and certain bacteria such as Campylobacter Jejuni. Patients diagnosed

regulation of smooth muscle and cardiac muscle. In the central nervous system acetylcholine is believed to be involved in the sleep-wake cycle‚ learning‚ memory‚ and mood. Acetylcholine is synthesized from choline and acetyl coenzyme A through the action of the enzyme choline acetyltransferase and becomes packaged into membrane-bound vesicles. After the arrival of a nerve signal at the termination of an axon‚ the vesicles fuse with the cell membrane‚ causing the release of acetylcholine into the synaptic

The History of Cell Theory As we all probably know today‚ every single living being is made up by cells the building blocks of life. As much as we would like to take this fact for granted‚ we cannot help but acknowledge and remember the works and discoveries of earlier scientists which all contributed to our today’s understanding of the cell theory. The cell theory being; all living things are composed of one or more cells‚ cells are organisms’ basic units of structure and function‚ and cells

Short Term Memory After reading several articles on short term memory‚ I noticed mostly everyone defines it differently. The most frequent definition is a system for temporarily storing and managing information required to carry out complex cognitive tasks such as learning‚ reasoning and comprehension. It is involved in selection‚ initiation and termination of information - processing functions such as encoding‚ storing‚ and retrieving data. Short term memory is the little thing that completely
