What Causes Optical Illusions? Optical illusions are how the eye sees the illusion. Most people now believe that seeing optical illusions has to do with perspective‚ or the way you look at something. The concept of optical illusion was first used by the Greeks. They built their temples so that the roof was slanted. This gave the illusion that the temple was actually standing straight. We get used to how things are supposed to be‚ and sometimes our brain gets the wrong message. Our brain puts

and to prevent further injuries. For example. if the subject touches a hot boiling kettle their initial reactions steps are: 1) somatic receptor received stimuli a "danger" stimul 2) afferent nerve senses signals to CNS 3) integrate information to decide what to do next 4) efferent nerve carry motor impulse ti muscle 5) effectors then will quickly remove hand away from kettle to aggravate anymore pain. In contrast‚ slow reaction time may come with unaffordable consequence. the given example is not

Krabbe disease is a disorder inherited from parents‚ which destroys the myelin coat of nerve cells throughout the nervous system and the process is called demyelination. Demyelination inhibits the transmission of nerve impulses and that hinders the communication of the brain and the body and that results in disability (Mayo Foundation for Medical Education and Research‚ 2016). Dr. Knud. H.Krabbe diagnosed this disorder in 1916 (Arizona Board of Regents‚ 2015). Krabbe disease is a body recessive disorder

Receptor cells sense the taste and pass on the message to attached nerve cells. The more you have‚ the more sensitive you are to the taste. tongue- pushes food together into a bolus for swallowing.

Connective Epithelial‚ and muscular tissues. From Tissues to organs Cells combine to form tissues and tissues combine to form organs. Cells combine to form four primary tissues: - Epithelial tissue - Connective tissue - Muscle tissue - Nerve tissue BACKGROUND:A tissue is a group of cells that have a similar shape and function. Different types of tissues can be found in different organs. In humans‚ there are four basic types of tissue: epithelial‚ connective‚ muscular‚ and nervous

the myelin sheath. A many-layered white‚ lipid and protein covering produced by the neuroglia that is called the myelin sheath surround the axons of most neurons. The sheath electrically insulates the axon of a neuron and increases the speed of nerve impulse conduction. Axons with such a covering are said to be myelinated whereas those without it are said to be unmyelinated. Two types of neuroglia produce myelin sheaths: neurolemmocytes and oligodendrocytes. In the PNS‚ neurolemmocytes form myelin

There are many ways in which substances can move across the cell membrane and in which then helps in the function of the body (cells‚ tissues and organs) overall. There are 3 processes that a substance can move across the membrane‚ theses are diffusion (simple and facilitated)‚ osmosis and active transport. Both diffusion and osmosis are passive processes‚ which mean they do not need energy to occur‚ whereas active transport does require energy. All three processes are involved in many functions
