10/21/14 Nervous system: one of the eleven major body organ systems in animals; coordinates and controls actions of internal organs and body systems; receives and processes sensory information from external environment; coordinated short-term reactions to these stimuli. Cell body: the part that contains the nucleus and most of the cytoplasm and the organelles. Axon: sends messages away from the cell body to other neurons. Dendrite: short‚ highly branched fibers that carry signals toward the cell

The brain does most of the information processing‚ storing‚ thinking and remembering. c. What parts of your nervous system allowed you to move your muscles to write the answer? What did those parts do? Somatic nervous system: this portion of the peripheral nervous system carries messages to and from the sense organs‚ skin‚ and muscles. The somatic nervous system controls most of your muscles and sends signals from senses‚ such as touch and doing something like typing. When you think of something to

The autonomic nervous system (ANS) consists of three main anatomical divisions: sympathetic‚ parasympathetic and enteric nervous systems. The sympathetic (SNS) and parasympathetic (PNS) systems provide a link between the central nervous system and peripheral organs. The sympathetic nervous system originates in the spinal cord. Specifically‚ the cell bodies of the first neuron (the preganglionic neuron) are located in the thoracic and lumbar spinal cord. Axons from these neurons project to a chain

Measurement of Heart Rate for Autonomic Nervous System Abstract: The Autonomic Nervous System lab was designed to measure reaction times by using a variety of tests that affect the heart rate. These tests were the startle‚ stroop‚ Valsalva maneuver‚ diving reflex‚ and a test of our choice. The test our group chose to measure the heart rate in response to doing a trust fall to anticipate the stress right before the fall. To begin this lab we chose a participant‚ and then hooked their finger

We are exposed to stress daily and in a multitude of ways that may at first seem meaningless‚ such hearing someone begin to speak or seeing a movement in our peripheral vision. Although these events may seem mundane‚ our body reacts to even these small events by setting in motion the stress response. Schafer (2000) states that even while talking a person’s blood
