Chapter 48 Nervous Systems Lecture Outline Overview: Command and Control Center The human brain contains an estimated 1011 (100 billion) neurons. Each neuron may communicate with thousands of other neurons in complex information-processing circuits. Recently developed technologies can record brain activity from outside the skull. One technique is functional magnetic resonance imaging (fMRI)‚ which reconstructs a 3-D map of the subject’s brain activity. The results of brain imaging and other

These systems function interdependently to enable an individual run successfully in a race immediately the pistol shoots (Oleksy‚ 2010).

Spinal Cord Motor Activity Classification of Reflexes " 1- Somatic reflexes : that you are aware of them 2- Autonomic Reflexes : that control visceral organs. Examples of spinal reflexes‚ involving spinal nerves and the spinal cord‚ include: 1- extensor reflex: leg proprioceptors trigger limb extension 2- myotatic (stretch) reflex: muscle stretch is resisted by reflex contraction of the muscle 3- withdrawal (flexion) reflex: limb flexes to withdraw from a noxious stimulus

the affective state a person is currently experiencing (or expressing for strategic purposes in social interaction). This assumption appears reasonable given that most affective states involve physiological reactions (e.g.‚ changes in the autonomic and somatic nervous systems)‚ which in turn modify different aspects of the voice production process. For example‚ the sympathetic arousal associated with an anger state often produce changes in respiration and an increase in muscle tension‚ which influence

Chapter 3 The Biological Bases of Behavior Communication in the Nervous System * Nervous Tissue: The Basic Hardware * Neurons are individual cells in the nervous system that receive‚ integrate‚ and transmit information. * The soma‚ or cell body‚ contains the cell nucleus and much of the chemical machinery common to most cells. * Dendrites are the parts of a neuron that are specialized to receive information. * The axon is a long‚ thin fiber that transmits signals

Abstract When deciding on a career many people consider the type of work‚ the hours involved‚ and the salary; what they fail to consider is the stress factor. A fact that is not taught in school is that different types of careers involve different levels and types of stress. However‚ not all stress is bad‚ some stress is actually good‚ and the human body requires a certain amount of stress to get motivated. The bad stress is called distress when it reaches dangerous levels. The good stress is called
