HKCEE Human Biology 2004 I Q2c Essays (p. 16-31) 12 Nerve impulses are electrical messages transmitted along nerve fibres at high speed. 1m When a nerve impulse arrives the ending of an axon‚ it stimulates the ending to release neurotransmitters. 1m The neurotransmitters diffuse across the synapse 1m and stimulate the dendron of the next neurone to generate a nerve impulse to continue the transmission. 1m Importance: This ensures nerve impulses travel in one direction only. 1m Most neurones have more

the connections between neurons in the brain‚ gain insight into the regulation of appetite and metabolism. The ARC and VMH has long been thought of as satiety centers. Studies that investigate the role of the arcuate nucleus in the hypothalamus‚ in regulating appetite and metabolism‚ have targeted two chemically identified neuronal types within the ARC: anorexigenic pro-opiomelanocortin (POMC) neurons and orexigenic neuropeptide Y (NPY)/agouti-related peptide (AgRP) neurons. The melanocortin α-melanocyte

the ability to recognize and share feelings of others‚ has been in our brains since the beginning of time. It was discovered by the Greeks which they called it ‚ “Empatheia” meaning‚ “in feeling.” Then a German psychologist named Robert Vischer in 1837 and he called it “Einfühlung‚” meaning “feeling into.”(Stueber‚ 2013) Vischer wrote a book called‚ “Über das opstiche Formgefühl: Ein Beitrag zu Aesthetik.”(Schott‚ 2015) In this book Vischer describes how empathy is based on sense perception such

Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

hero for that matter. A hero is a person who sacrifices something‚ but a hero doesn’t always have to sacrifice. Being a hero could be giving a homeless person food or money. A hero is a person that does something selfless. In the Messenger‚ Mattie sacrificed himself by healing the Forest for everything and everyone he loved. Even though humans or animals don’t have powers‚ the idea is the same. In the movie October Skies‚ Homer Hickam goes to work in the coal mines for money because

Overview Of Neuron Structural and Functional Properties and Electric Circuit Parameter Models from a Cellular Perspective. Neurons serve the purpose of receiving signals coming from neighbouring neurons; they assimilate these signals‚ and generate nerve pulses. They then conduct and transmit these nerve pulses to other neurons which are capable of receiving them. Neurons are the structural constituents of the brain. Typically‚ neurons are five to six orders of magnitude slower than silicon logic
