Also‚ there has been a disruptions of the sympathetic fibers of his autonomic nervous system therefore it can no longer stimulate the heart. Allen likely has spinal shock. 2.

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)

Chapter 2- Neuroscience and biological foundations Glial Cells (three types): Make up about 90% of the brain’s total cells. They also supply nutrients and oxygen‚ perform clean up tasks‚ and insulate one neuron from another so that their neural messages are not scrambled. Oligodedreocytes: helps to create the myelin sheath. Purpose speed up communication in the brain. Insulate axons. Makes Neural transmissions. Microglia: Special immune cells in the brain. They can detect unhealthy and damaged

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

This perspective shows the psychologist which areas of systems interact to influence behavior. Humans are biopsychosocial systems‚ in which biological‚ psychological‚ and social-cultural factors interact to influence our behavior. NEURAL COMMUNICATION 2-2: What are neurons‚ and how do they transmit information? Neurons are the basic components of the nervous system. The body uses these neurons in its electrochemical information system rather quickly. A neuron receives signals through its dendrites

Adrenergic medications affect the four receptors‚ a1‚ a2‚ B1 and B2. The sympathetic nervous system triggers the secretion of epinephrine and norepinephrine. Epinephrine is a hormone and norepinephrine functions as a hormone and neurotransmitter. First we will take a look at the Alpha 1 receptors. These Alpha 1 receptors cause vasoconstriction of vascular smooth muscles. They are located on the post synaptic membranes of effector organs‚ such as on gastral and urinary sphincters. Some are located
