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

A nerve cell; the basic building block of the nervous system. The bushy‚ branching extensions of a neuron that receive messages and conduct impulses toward the cell body. The extension of a neuron‚ ending in branching terminal fibers‚ which messages pass to other neurons or to muscles or glands.

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

inform the central nervous system of the position and movement of the various parts of the body. Each stretch receptor consists of specialized muscle fibers and the terminal branches of sensor neurons. The muscle fibers and sensor neuron endings are very closely associated and are encased in a sheath of connective tissue. Visceral receptors monitor the conditions of the internal organs. Most responses to their stimulation by an organ are carried out by the autonomic system. Several visceral

Nicotine. Nicotine is a toxic colorless or yellowish oily liquid ‚ which is the chief active constituent of tobacco. It also acts as a stimulant in small doses ‚ but in larger amounts it blocks the autonomic nerve and skeletal muscle cells. The autonomic nerve is the part of the nervous system responsible for control of the bodily functions not consciously directed‚ such as breathing‚ the heartbeat‚ and digestive processes. Addiction is a condition that results when a person ingests a substance

striated. Furthermore‚ it has slight similarities to the smooth muscles‚ because its contractions are not under conscious control. On the other hand this type of muscle is highly specialised. It is under the control of the autonomic nervous system‚ however‚ even without nervous imput contractions can occur due to cells called pacemaker cells. Cardiac muscle is highly resistant to fatigue due to the presence of a large number of mitochondria‚ myoglobin and a good blood supply allowing continuous aerobic

to long term (just a few months or possibly forever) becomes distorted and the brain is unable to store long term memories or knowledge anymore [2‚ 12]. Effects on Motor Control A serious consequence of drinking is damage to the central nervous system (CNR). When a person decides they want their body to perform an action‚ the CNR sends a signal to the brain which will relay this information to the part of the body needed to perform the action. Since alcohol is a depressant of the CNS‚ it
