The four groups are as follows in no specific order: Autocrine‚ paracrine‚ neurotransmitter‚ and endocrine. Neurotransmitter chemical messengers are let out by neurons where they are deposited into the synaptic cleft. Neurotransmitter chemical messenger travel short distance’s activating adjoining cells by triggering nearby cells. When my daughter gets on the stage to play her instrument she becomes nervous

Neurotransmitters are chemicals found in the synaptic vesicles which‚ when released‚ have an effect on the next cell. 13.The excitatory neurotransmitter causes the receiving cell to fire. 14.The agonists mimic or enhance the effects of a neurotransmitter on the receptor sites of the next cell‚ increasing or decreasing the activity of that cell. 15.The spinal cord is a long bundle

and Dendrites are both arm-like extensions from the cell body. Dendrites are short and extremely branched processes that function as the input regions of neurons. Axons are long branched processes that contain end bulbs‚ these bulbs secrete neurotransmitters‚ so axons function as the output. 3. What is myelin? How does the myelination process differ in the CNS and PNS? Myelin sheath is a fatty covering around long axons that protect it and help increase the speed of nerve impulse transmission

The Chemical Effects of Nicotine on the Central Nervous System and the Adrenal Medulla An Australian Health Survey conducted in 2011-2012 concluded that 3.1 million Australians are current smokers. (Australian Bureau of Statistics‚ 2013). This means that 14% of Australia’s population are current smokers compared to more than 40% in the 1980’s – a dramatic decrease with the smoking rate continuing to decline each year.
