Chapter 8.1 1. List the four biological levels of organization in a human in order from most simple to most complex. Cells‚ tissues‚ organs‚ organ systems 2. Define the term “homeostasis”. The tendency of the body to maintain a relatively constant internal environment. 3. What does the term “feedback system” refer to with respect to homeostasis? A cycle of events in which a variable‚ such as body temperature‚ is continually monitored‚ assessed‚ and adjusted. 4. List the three components

between 10 to 100 billion neurons; each of which making 13 trillion connections with each other through electrochemical messages that allow people to respond to stimuli‚ from the environment or from internal changes in a person’s body. The neurons send these electrochemical messages through neurotransmission. Electrical impulses traveling down the axon (body) of a neuron‚ instigates the release of neurotransmitters‚ which travel over the synapse‚ which is the gap between two neurons. Once the neurotransmitters

1. Differentiate between the somatic nervous system and the ANS. Somatic nervous system includes all of the neural pathways (neurons) that result in voluntary actions‚ basically anything that you can tell your brain to do like move your arm or stick out your tongue. The autonomic nervous system includes all of the neural pathways that result in involuntary actions‚ like your brain telling your eyes to blink or your intestines to contract‚ basically anything that you cannot control. 2.

What is psychology? The scientific study of behavior and mental processes Development of psychology as a science Wilhelm Wundt founded the first psychology laboratory. Student of Wudnt ’s‚ E.B. Titchner named Wundt ’s approach structuralism. William James gave field an "American Stamp‚" invented functionalism Contemporary approaches to psychology Biological Approach (focus on the body) Neuroscience Behavioral Approach (behavioral responses and their environmental determinants) Psychodynamic

Nervous tissues are made up of two main types of cells: nerve cells/neurons and neuroglia. The main functions of nervous tissues are to react to stimuli and generate impulses to various organs in the body. http://www.occc.edu/deanderson/dennis-tutorial/dennis-jpeg/Nervous%20Tissue-low%20mag%20D-1%20copy Nerve cells and Neuroglia Neuroglia do not transmit nerve impulses themselves‚ but they are important to the neurons because they are responsible for supporting them by providing the nutrition

is to monitor stimuli occurring inside and outside the body‚ process and interpret this sensory input‚ and respond by activating effector organs. It consists of the Central Nervous System (brain and spinal cord)‚ and the Peripheral Nervous System (neurons that carry messages to and from the CNS). 2. Describe the composition and function of the cell body. How are xons and dendrites alike? How do they (structurally and functionally) differ? The nerve cell body contains the nucleus‚ rough ER

cell is a type of neuron which has two extensions. Bipolar cells are specialized sensory neurons for the transmission of special senses. As such‚ they are part of the sensory pathways for smell‚ sight‚ taste‚ hearing and vestibular functions They are found in the vestibulocochlear nerve‚ but reference to bipolar neurons is usually to cells in the retina. A unipolar cell is a type of neuron in which only one protoplasmic process (neurite) extends from the cell body. Most neurons are multipolar‚ generating

located in the cell membrane stimulating the receiver cell. The signals mention before are the two main ways of communication of neurons in your nervous system. Also ionic channels are seen that they stimulate and they activate the cell to send electrical signals through central nervous system. Epilepsy is known as a brain disorder in which clusters of nerve cells or neurons in the brain sometimes transmit signals in an abnormal way. There have been diagnosed more than 30 types of seizures‚ which generally

essential to living – these are called nerve cells. Nerve cells‚ also known as neurons‚ “are the basic information processing structures” (Stufflebeam). There are about 100 billion of these neurons in our nervous system and are the most essential cell in it. Located in brain as well as the spinal‚ there are different types of nerve cells; including: sensory neurons‚ motor neurons‚ and interneuron (Boeree). The neuron is a cell that is structured similarly to a common animal cell‚ but has a few things
