Considering the nervous system‚ please briefly explain how the electrically excitable membrane changes its electric potential. In other words‚ how is the cell membrane excited? At the surface of the cell membrane‚ there are three classes of gated channels exist‚ chemically gated or ligand-gated channels‚ voltage-gated channels‚ and mechanically gated channels. Originally‚ at the resting membrane potential‚ most of the gated channels are closed. However‚ when these gated channels open‚ the movement of

Nerve and neuron sound similar to most people‚ but they are two different components of the body (Martini‚ 375). Nerves are found only in the peripheral nervous system‚ while neurons are found in the brain‚ spinal cord‚ and peripheral nerve (Martini‚ 375). Neurons are nerves cells that are specialized for intercellular communication (Martini‚ 375). A neuron is composed of a cell body‚ dendrites and axon (Marieb‚ 376). A nerve is a bundle of axons or dendrites that is wrapped in connective tissues

information to and from all parts of the body. Neuron: the basic cell that makes up the nervous system and that receives and sends messages within that system. Dendrites: branchlike structures that receive messages from other neurons. Soma: the cell body of the neuron responsible for maintaining the life of the cell. Axon: tubelike structure that carries the neural message. Glial cells grey fatty cells that provide support for the neurons to grow on and around‚ deliver nutrients to neurons‚ produce myelin

1. Explain the role of neurotransmitters in formation of drug addiction. As we can see from the video assigned to us this week‚ dopamine is a neurotransmitter that plays a role in the brain’s response to the presence of drug abuse. Dopamine is responsible for movement‚ regulation of heart rate‚ motivation and how a person perceives an experience either being painful or pleasurable. Pain causes for dopamine levels to drop whereas pleasurable responses increase dopamine levels. All drugs that become

Duchenne muscular dystrophy‚ familial colon cancer‚ breast cancer and many more. Once the human genome is mapped‚ the next logical step is gene therapy‚ in which a missing gene is added or a defective one is removed. One of the main issues to consider when discussing genetic engineering in humans is the fact that altering the genes of human embryos often creates problems. Genetic correction of one defect can create other new defects. One of the latest developments in the field of genetics has been
