Physiological changes essay Many changes happen to an older person’s body as they age. Internal and external changes bring about fresh challenges to staying healthy. The physiological changes include gastrointestinal changes‚ muscular and skeletal system changes‚ as well as changes in organs. Along with these issues‚ senses begin to diminish. Everyday tasks become increasingly more difficult. Simply moving around during daily routines becomes difficult with age. These changes can cause secondary

Two major types of literature are Poetry and Prose "Poetry A poem is defined as a composition written in verse (although verse has been equally used for epic and dramatic fiction). Poems rely heavily on imagery‚ precise word choice‚ and metaphor; they may take the form of measures consisting of patterns of stresses (metric feet) or of patterns of different-length syllables (as in classical prosody); and they may or may not utilize rhyme. One cannot readily characterize poetry precisely. Typically

PHYSIOLOGICAL PSYCHOLOGY Physiological psychology focuses on the relationship between our biological makeup and our behaviour and experiences. This area of psychology can be very convincing. For example we do know that the structure of our nervous system (including our brains) and the action of chemicals can have an effect on our behaviour. Some physiological psychologists take a reductionist argument to answer the above question. That is‚ they argue that behaviour and experiences can

Experiment 4: Conductivity of electrolyte solutions (Dated: October 29‚ 2009) I. INTRODUCTION Pure water does not conduct electricity‚ but any solvated ionic species would contribute to conduction of electricity. An ionically conducting solution is called an electrolyte solution and the compound‚ which produces the ions as it dissolves‚ is called an electrolyte. A strong electrolyte is a compound that will completely dissociate into ions in water. Correspondingly‚ a weak electrolyte dissolves

Upper motor neurons and lower motor neurons act to carry nerve impulses from the brain out to the muscles in the body. Upper motor neurons supply input to the lower motor neurons. They do this by either synapsing directly to lower motor neurons‚ or by synapsing with a local circuit neuron‚ which then synapses with a lower motor neuron. The upper motor neurons originate in the motor region of the cerebral cortex or brainstem. The neurons from the cerebral cortex are important for planning‚ initiating

summation Summation can be defined as the method which neurons use to communicate with each other‚ determining if the cumulative postsynaptic potential in the neuron is enough to pass the threshold for firing. There are two types of summation‚ spatial summation and temporal summation. Both types of summation are similar in that they work to strengthen the EPSP of a neuron‚ meaning they help create more postsynaptic potential so that neurons are more likely to fire. Spatial summation and temporal

in the body is extremely large. There are many different forms of fluid throughout the body‚ such as blood‚ urine‚ hormones‚ cerebral spinal fluid‚ water‚ albumin‚ and bile. The fluids that make up the body are required for homeostasis. There are many different functions of body fluids such as transporting nutrients‚ waste and gases‚ transforming food into energy and generate electrical activity to power body functions. Physiologic Fluid Compartments The major fluid compartments in the body are intracellular

carried out over more than 30 years at the University of California at Berkeley‚ suggest that perception cannot be understood solely by examining properties of individual neurons‚ a microscopic approach that currently dominates neuroscience research. We have found that perception depends on the simultaneous‚ cooperative activity of millions of neurons spread throughout expanses of the cortex. Such global activity can be identified‚ measured and explained only if one adopts a macroscopic view alongside
