Sensory neurons send information from the body’s tissues and sensory organs inward to the brain and spinal cord‚ which process the information. Motor neurons carry outgoing information from the central nervous system to the body’s tissues.Interneurons in the central nervous system communicate internally and intervene between the sensory inputs and the motor outputs. The axons of some neurons are encased by a myelin sheath‚ which helps speed their impulses. A neural impulse‚ or action

How do the different perspectives in psychology compare and contrast? Slide 2: Psychology Comes from two Greek words… psyche‚ meaning “life” or “self” logos‚ referring to reasoning and logic Slide 3: Psychology’s Roots Psychology Study of behavior and mental processes aims to describe and

I. Title – The Effect of Volume on Heart Rate II. Problem/Research question – Your heart rate can be affected and changed using a variety of things. One thing that can cause your heart rate to change is the volume of audio. How does the volume of an audio track affect your heart rate? If the volume of an audio track is increased‚ the number of hearts beats per minute will increase as well. III. Variables – ❖ Independent Variable ➢ The volume of the audio track ❖ Dependent

signal-transducing molecules ("second messengers"messengers") in the post-synaptic cells (Cooper‚ Bloom and Roth 1996). Nine compounds -- belonging to three chemical families -- are generally believed to function as neurotransmitters somewhere in the central nervous system (CNS) or periphery. In addition‚ certain other body chemicals‚ for example adenosine‚ histamine‚ enkephalins‚ endorphins‚ and epinephrine‚ have neurotransmitter-like properties‚ and many additional true neurotransmitters may await discovery.

communication systems in the brain The Nervous System and the Endocrine System Nervous System: extensive network of nerve cells that carry messages in pulses of electrical and chemical energy throughout the body. This is the network that first comes to your rescue by accelerating you heart and tensing your muscles for action. Endocrine System: a slower acting communication network that sends a follow up message that supports and sustains that support the emergency response initiated by the nervous system
