The central nervous system, which is includes the brain and the spinal cord, processes and coordinates all incoming sensory information and outgoing motor commands, and it is also the seat of complex brain functions such as memory, intelligence, learning, and emotion. The peripheral nervous system includes all neural tissue outisde of the central nervous system. It is responsible for providing sensory, or afferent, information to the central nervous system and carrying motor, efferent, commands out of the body's tissues. Voluntary motor commands, such as moving muscles to walk or talk, are controlled by the somatic nervous system, while involuntary motor commands, such as digestion and the heart, are controlled by the autonomic nervous system. The autonomic nervous system is further divided into two systems. The sympathetic nervous system, sometimes called the "fight or flight" system, increases alertness, stimulates tissue, and prepares the body for quick responses to unusual situations. In contrast, the parasympathetic nervous system, somestimes called the "rest and response" system, conserves energy and controls sedentary activities, such as digestion. http://www.v-com.com/erichubscherpfisite_023.htm Thu, 15 Nov 2007 13:45:47 GMT Eric Hubscher This bicep muscle is attached to the bone via tendons. The bones, seated on cartilage, rotate about the joint and are held into place by ligaments. http://www.v-com.com/erichubscherpfisite_023.htm Thu, 15 Nov 2007 13:45:47 GMT Eric Hubscher Limbs move in a controlled manor through tension. In this example, in order for the bicep to contract and move the arm from the elbow to the hand inward, the tricep muscle relaxes (elongates). This allows the bicep muscle to contract and move the arm about the joint. If however the tricep and bicep muscles would contract at the same time, the lower arm would not move. Meaning, both muscles would be trying to move the arm in opposite directions at the same time. Impossible. Result would most likely be a muscle cramp. http://www.v-com.com/erichubscherpfisite_023.htm Thu, 15 Nov 2007 13:45:47 GMT Eric Hubscher It Is The Transverse Abdominis That Really Matters ! http://www.v-com.com/erichubscherpfisite_023.htm Thu, 15 Nov 2007 13:45:47 GMT Eric Hubscher
