SCI is an unexpected and devastating disease‚ which is caused by direct mechanical damage to the spinal cord and usually leads to motor and sensory dysfunction subject to the condition of injury. SCI is one of the major causes of death and disability in clinical situations. SCI brings enormous psychological and economic burdens to individual family as well as the whole society as a whole. (1‚2‚3‚4‚5) In the United States there are approximately 282‚000 people suffering from SCI and an average growth

specialised neurons that produce and release ADH into the body‚ ADH is manufactured in the cell body within these cells‚ lying in the hypothalamus. ADH flows through the axon into the terminal bulb in the posterior pituitary gland‚ where it is stored until needed. When neurosecretory cells are stimulated‚ action potentials are sent down their axons releasing ADH‚ which enters the blood capillaries running through the posterior pituitary gland then is transported around the body acting on cells of collecting

Mammalian Physiology Homework on Drug Mechanisms 1. Release and degradation of the neurotransmitter inside the axon terminal. Drug: Reserpine Pharmacology: Most often used to treat mild to moderate hypertension. Mode of action: Reserpine inhibits the ATP/MG2+ pump responsible for packaging neurotransmitters into vesicles in the presynaptic neuron. This causes the free neurotransmitters to be degraded by MAO‚ leading to a reduction in catecholamines. 2. Increased neurotransmitter release

neurotransmitters and cause neurons to fire. Antagonists are a second type of drug. These attach to receptor sites on a neuron to stop its ability to fire. Finally‚ a third type of drug is a reuptake inhibitor. These drugs work by attaching to axon branches so that the axon terminal cannot suck up the leftover neurotransmitter in the synapse‚ thus creating an excess of the

PSY 101 Review Sheet #1 Chapters 1-3 1. What does psychology study? Psychology is the scientific study of behaviors and mental processes. Behaviors include all outward or overt actions and reactions‚ mental processes include all internal covert activities of the mind. The goals of psychology are to describe‚ explain‚ predict‚ and control the behaviors and mental process of both human and animals. 2. Explain Structuralism. Structuralism is the study of the structure of the mind. It’s based
