Biological Basis of Behavior William James- mental activity is also physiological activity Neuron- basic unit of the nervous system *Each neuron is a living cell with a nucleus and other parts common to all cells. Three main parts of the neuron: 1. Dendrites: the receiving part of the nucleus 2. Cell body (Soma): The processing part Electrochemical Transmission 3. Axon: the transmitting part Normal habit change: Doing the same behavior over and over again (same neurons being used over and over)

Three functions of the nervous system: • receive information; input • integrate information with past experiences; processing • Guide actions; output. Brain can adjust the impact

similar to those of benzhexol. It also has weak antihistaminic and local anaesthetic properties. Antimuscarinic drugs are defined by‚ A Dictionary of Nursing (2008) as those inhibiting the action of acetylcholine‚ a neurotransmitter in the parasympathetic nervous system. These drugs relax smooth muscle‚ decrease the secretion of saliva‚ sweat and digestive juice‚ and dilate the pupil of the eye. As mentioned already orphenadrine is used as the hydrochloride in the symptomatic treatment of parkinsonism

If it tasted good it was all right for her. Her lack of anxiety (worry) about the diet kept her fit. For a good digestion you need to be perfectly relaxed in what we are eating. Only then‚ the parasympathetic nervous system will help us in good digestion. We should never worry about our diet system when we start to eat. On the other hand if we eat in fear and tension body refuses to co-operate and would suffer from cancer

If your mind interprets a stressful event as an emergency threat‚ it triggers an immediate response in the autonomic nervous system. Your stress response kicks in and activates the sympathetic nervous system (SNS). Your body is flooded with hormones that heighten the senses‚ increase heart rate and blood pressure‚ and focus the brain’s activity. The parasympathetic nervous system (PNS)‚ which is responsible for physical relaxation and emotional calm‚ becomes overwhelmed by this sympathetic response

Chapter 2 Outline The Biological Perspective Neuron A specialized cell transmitting nerve impulses; a nerve cell Dendrites Dendrites are treelike extensions at the beginning of a neuron that help increase the surface area of the cell body and are covered with synapses Soma The soma is the cell body of a neuron. Axon The Axon of a neuron is a singular fiber that carries information away from the soma to the synaptic sites of other neurons (dendrites and somas)‚ muscles‚ Glial

The division of the autonomic nervous system affected‚ that’s causing Nick’s GI symptoms is the parasympathetic system. E. Autonomic reflexes adjust heart rate‚ force of ventricular contraction‚ and blood vessel diameter. (how blood pressure is controlled) F.
