treat mild to moderate hypertension. Mode of action: Reserpine inhibits the ATP/MG2+ pump responsible for packaging neurotransmitters into vesicles in the presynaptic neuron. This causes the free neurotransmitters to be degraded by MAO‚ leading to a reduction in catecholamines. 2. Increased neurotransmitter release into the synapse. Drug: Black Widow Venom Pharmacology: Neurotoxin. Mode of action: Alpha-latrotoxin (a-LTX) is the three-dimensional protein toxin unique to widow spiders. This protein

Role of Brain in Cognitive Functions Cathy Moyer-Larsen Role of Brain in Cognitive Functions Cognitive brain functions enable the ability of the brain to attain information in a meaningful way. Cognitive psychology is what happens in the mind. Two important conditions concerning the ability to use cognitive brain functions is the current mood and health (Willingham‚ 2007). Cognitive functions originate in the part of the brain called the cerebrum. Majority of brain mass is in the cerebral

other molecules on synapse and synapse transmission. The synapse is the small gap separating two neurons‚ the presynaptic neuron (neuron that carries the impulse to the synapse‚) and postsynaptic neuron (neuron that carries the impulse away from the synapse.) It separates the axon terminals of the presynaptic neuron from the postsynaptic neuron. The synapse is made of three major parts: a presynaptic neuron‚ a postsynaptic neuron‚ and a synaptic cleft. The presynaptic neuron contains the neurotransmitters

There are three major brain divisions. They are the cerebrum‚ the brainstem‚ and the cerebellum. The cerebrum contains 40% of the weight of the brain and is founded in the superior part of the brain. This portion of the brain has many functions and lobes which perform certain functions. The frontal lobe is involved with “activating and controlling both fine and complex motor activities.” This involves speech. It is also involved with the executive functions‚ such as reasoning and rationalizing‚ among

The most basic similarity is that all living things are composed of one or more cells. This is known as the Cell Theory. • our knowledge of cells is built on work done with microscopes • English scientist Robert Hooke in 1665 first described cells from his observations of cork slices
