Elements 1 Neurons: The Basic Elements of Behavior Introduction to Psychology 101 Elements 2 The Basic Elements of Behavior The human body is a tremendous creation that is quite capable of performing a multitude of multifaceted movements and thoughts. In addition to its’ ability to move and think‚ the human body also allows numerous senses to become involved throughout ones daily routine. A person’s ability to think‚ remember‚ and experience emotion are all results of the body’s

occur. At the start my lab partner was calm resulting in the blood pressure to be around 125/59 with 55 beats per minute. The second time we did it‚ the numbers were fairly similar 126/59 and 62 beats per minute. At the beginning there is no action potential occurring or the pacemaker is not racing to make the heart beat quicker because the body is not using much energy since it is basically at a resting state. You can detect the heart beats by using the QRS EKG method where each one can represent

Information * The Neuron at Rest: A Tiny Battery * The resting potential of a neuron is its stable‚ negative charge when the cell is inactive. * The Action Potential * An action potential is a very brief shift in a neuron’s electrical charge that travels along an axon. * The absolute refractory period is the minimum length of time after an action potential during which another action potential cannot begin. * The All-or-None Law * The neural impulse

March 26‚ 2013 Lecture -The function of the eye is to convert photons of light into action potentials (nerve impulses). -The inner layer is a nervous tunic (made out of nerve cells)=retina. -Refraction: Bends light. -The purpose of the cornea and the lens is to take an object and focus every little detail of the object on the retina on the back of the lens. Upside down and backwards. -When light goes through medias‚ it bends. -Lens are suspended by ligaments behind the pupil. Suspensory ligaments

A. Tonic Spiking Most neurons are excitable‚ that is‚ they are quiescent but can fire spikes when stimulated. To test this property‚ neurophysiologists inject pulses of dc current via an electrode attached to the neuron and record its membrane potential. The input current and the neuronal response are usually plotted one beneath the other‚ as inFig.1(a).Whiletheinputison‚theneuroncontinuestofireatrain of spikes. This kind of behavior‚ called tonic spiking‚ can be observed in the three types of cortical

TOPIC 6‚ 11‚ & OPTION H: HUMAN HEALTH AND PHYSIOLOGY Digestive System Includes all the structures that are concerned with bringing food into the body to provide for the needs of the body’s cells. Each cell in an organism relies on a continuous expenditure of energy. Fats‚ carbs‚ and proteins are broken down during cellular metabolism and the energy derived from them is used to make ATP. The digestive system deals with: Ingestion‚ which is the bringing of nutrients into the body. Mechanical
