address this question: “Propose a possible explanation on why the light caused depolarization of the off-center ganglion cell?” we first have to describe the structure of the center -surround in the receptive fields of retinal. In the receptive field‚ there are cone photoreceptors that communicate with On and Off center bipolar cell and finally On and Off center ganglion cells that carry the action potential to the cortex. When light comes to the retina (eyes) it causes closing of channels in the

the functional role of amacrine cells in retinal dynamics. In this thought paper I will argue that together with the bipolar and ganglion cells‚ the amacrine cells operate in a parametric system similar to the feedback and feedforward systems found in motor control. In order to determine the role of the amacrine cells they needed to determine the method of bipolar convergence and divergence in ganglion cells. When stimulated individually‚ two different bipolar cells were able to elicit distinct post

him or her having Sickle Cell Disease. What this is is it’s a disease that is genetically inherited and it involves the red blood cells. Mutations in the HBB gene cause this disease. This disease is inherited in an autosomal recessive pattern‚ which means both copies of the gene in each cell will have mutations. The parents of offspring with an autosomal recessive gene each carry one copy of the mutated gene. The blood cells form an abnormal crescent shape (normal cells are in a disk form). The

Functions of the cells The functions of cells are shown in the body which is comprised entirely of cells. Every cell also has its own or more than one job to do. The cell membrane The cell membrane also known as the - plasma membrane. It consist of two layers of a fatty type substance. Its function is to protect the inside and the outside of the cell by allowing certain substances into the cell‚ while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some
