Lipids are made up of carbon‚ hydrogen and oxygen (phospholipids also contain phosphate) and are found in a wide variety of organisms from bacteria to eukaryotes where they perform a wide variety of useful functions. This essay will expand on these functions to describe the role of lipids. There are several types of lipid including triglycerides‚ steroids‚ waxes and phospholipids. Triglycerides are made up of three fatty acids combined with glycerol by an ester linkage meaning they are predominantly

black eye. In response to this‚ I underwent surgery for the Vagus Nerve Stimulator to be implanted in my chest. It is connected to wires that are wrapped around the nerve‚ which connects to the brain. It sends electrical impulses to the brain to interrupt the occurrence of a seizure. It gradually worked as they adjusted the device‚ and now I have not had a seizure in a long time. On the other hand‚ it stings when it sends the impulse‚ I cough‚ and lose my voice for a few minutes. The only real inconvenience

The depolarisation and repolarisation that takes place within a cell from that occurs gives rise to voltage of waveforms. With the human body each cell at this present time is generating electrical impulses like a voltage generator‚ which is a basic source of all the bioelectric potentials. With these bioelectric potentials they produce ionic voltages produced by the coordination of electrochemical activity within numerous cells. When the cells are in line the charges tend to migrate through the

cytoplasm are contained in the cell body. The axon starts from the cell body‚ dividing into smaller branches and then ends at the nerve terminals. The dendrites also branch from the cell body‚ receiving information from the other neurons. Axons from other neurons forms synapses at their ends‚ which cover the cell body and dendrites.(Myers‚ 2013)Neurons send messages by passing impulses through their axons. The axons have different lengths. They range between a fraction of an inch and three feet or more. A

Critically assess Descartes ’ three arguments for his claim that mind and body are distinct. The concept of Mind-Body dualism is one that has its roots in early classical philosophy‚ with both Plato and Aristotle setting out strong arguments for this philosophy of the mind. The most famous proponent of this theory though is the “father of Modern Philosophy”‚ René Descartes. This belief fundamentally stems from the appearance of humans having both mental and physical properties‚ properties which

retina. It must then pass through the inner layers of the retina to reach the photoreceptive layer of rods and cones. 2. When the photoreceptors are stimulated they transmit impulses to the bipolar cells that project to the ganglion cells of retina. 3. The axons from the ganglion cells converge at the optic disc to form optic nerve which enters the cranial cavity through the optic foramen. At the optic disc these axons acquire a myelin coat from oligodendrocytes of the CNS. 4. The optic chiasm is formed

Senses What are the human senses and how do they work? The human senses are faculties by which the human body perceives external stimulation. Humans have senses to help them experience the world around them. The five main senses are sight‚ hearing‚ taste‚ smell and touch. Each of these five senses consists of organs with a specialized structure that has receptors for specific stimulation. These receptors are linked to the nervous system and therefore the brain. Sight Sight is the sense

commonly used in literature when describing the neurological disease that is MS. MS is a disease of the central nervous system caused by a degeneration of the myelin sheath that insulates the nerves who’s function are to carry nerve impulses around the body. This inevitably results in dysfunction of neurological impulses and therefore neurological symptoms. (Goodman & Samkoff 2014) It is described as being an immune mediated disease with both genetic and environmental factors influencing its development
