Quiz #3 Josi Leger Neurons - Neurons are nerve cells that are located in the nervous system‚ the main function of the neurons is to send and transmit messages so that we may function and move. Dendrite – Are located on neurons and they look like tree shape stems‚ they are what sends the signals out from the neuron and they also receive signals along with sending electrical stimulations to the soma. Synaptic Gap – This is a small gap between the cell membrane and the synapse it separates the

INTRODUCTION TO PHYSIOLOGY AND HOMEOSTATIS PHYSIOLOGY 1.1 Intro to Physiology Physiology: the study of the functions of living things‚ how the human body works Two approaches explain the events that occur in body -purpose of the body process - mechanism in which the process occurs Physiologists view the body as a machine whose mechanisms of action can explained in terms of cause and effect sequences of physical and chemical processes. Physiology is closely related to anatomy: the

Neural & Synaptic Transmission The nervous system is made up of neurons and glila cells. Neurons are the basic communication links in the nervous system. Glila cell provide support for neurons and contribute to communication. Neurons normally transmit a neural impulse (an electric current) along an axon to a synapse with another neuron. The neural impulse is a brief change in neuron’s electrical charge that moves along an axon. It is an all-or-none event. Action potential triggers

What is Brain Chemistry? Brain chemistry or neurochemistry is the complex system which allows the brain to function with the use of chemicals known as neurotransmitters which move information around in the brain. Every person’s brain chemistry is slightly different‚ and a number of things can play a role in the levels of various neurotransmitters in the brain‚ and how those chemicals affect the brain’s function. It is believed that difference in brain chemistry may explain a variety of behavioral

The brain of an average human being contains 100 billion nerve cells or neurons. Billions more are found in other parts of the nervous system. Neurons come in all different sizes and shapes‚ but they all seem to be specialized to receive and transmit information. Neurons are made of neurons which contains chromosomes and genes‚ a cytoplasm which keeps the cells alive and a cell membrane that encloses the whole cell. Neurons are different from other cells because they have small fibers that branch

They are generally found in many of the body’s tissues such as within the cytoplasm of the cells of the heart‚ liver‚ muscle‚ and skin but the signs and symptoms of the disease are limited to the nervous system. The disease presents with epileptic seizures followed by progressive central nervous system degeneration beginning with myoclonic seizures‚ tonic-clonic seizures‚ focal occipital seizures‚ intellectual decline‚ severe motor and coordination deterioration‚ and constant myoclonus (Gentry‚

growth and development does occur. Following is a description of how the pathways of this intricate web are followed and the mistakes which happen when they are not. The impressive process of differentiation changes a single-cell into a complicated system of cells as distinct as bold and bone. Although embryonic development takes approximately nine months‚ the greatest amount of cellular differentiation takes place during the first eight weeks of pregnancy. This period is called embryogenesis. During
