with a sensory experience. This begins when the sensory receptors receive energy from a particular stimulus‚ which trigger receptor cells. The physical energy is converted into electrochemicals‚ then passes along sensory nerves‚ to the central nervous system where the brain receives the energy as a detailed message. However‚ not all physical energy produces a sensation. A minimum intensity‚ termed absolute threshold‚ must be achieved in order to produce a sensation. Perception takes place when the

A bipolar cell is a type of neuron which has two extensions. Bipolar cells are specialized sensory neurons for the transmission of special senses. As such‚ they are part of the sensory pathways for smell‚ sight‚ taste‚ hearing and vestibular functions They are found in the vestibulocochlear nerve‚ but reference to bipolar neurons is usually to cells in the retina. A unipolar cell is a type of neuron in which only one protoplasmic process (neurite) extends from the cell body. Most neurons are multipolar

Test 01 - Introduction Receptor cells use chemical transmitters to communicate with relay cells or afferent nerve fibers. In all sensory systems‚ accessory structures modify‚ in some way‚ the stimulus going to the receptor surface. Receptors are electrically polarized cells and therefore have a resting membrane potential. Stimuli produce‚ in the appropriate receptors‚ a change in the electrical properties that is known as the receptor or generator potential. The two ways in which sensory stimuli

Per the Center for Disease Control and Prevention (CDC)‚ “Benzene works by causing cells not to work correctly. For example‚ it can cause bone marrow not to produce enough red blood cells‚ which can lead to anemia. Also‚ it can damage the immune system by changing blood levels of antibodies and causing the loss of white blood cells.” (CDC‚ 2013) The extend of benzene poisoning depends on length of exposure‚ preexisting medical conditions‚ route‚ and amount. At the Love Canal‚ there was over 6‚900

builds from biological molecules‚ which are organized into complex structures referred to organelles‚ which are also one of the properties of cells. Within this complex system‚ life can be understood as many descending levels. From molecules‚ organelles are formed‚ organelles create cells‚ cells make up tissue‚ tissues are part of systems and organs and from organs organisms are formed. This hierarchy of biological organization makes up our ecosystem and describes the web of complex interactions. This
