uestion : You are at a basketball game and the arena is packed; the crowd is evenly split between fans of the two teams. At one point‚ the referee makes a call. Half of the fans yell insults; the other half of the fans shout their approval. The event reminds you of the topic of today’s lecture in psychology class. What was the likely topic of the lecture? Student Answer: bias experiments psychoanalysis extraneous variables Instructor Explanation: Chapter 1

cartilage (the substance that lines the joints between bones and gives structure to the nose and the external ears). C) Nervous tissues consist of neurons and glial cells. Neurons are individual cells that generate and conduct electrical signals‚ or nerve impulses‚ around the body. Nervous tissues support the information-processing functions of neurons in various ways. D) Muscle Tissues account for most of the body mass of vertebrates. They consist of elongated cells that contract to generate forces

It is a short extension of the cell body And send signals toward the cell body and the cell body conducts nerve impulses which in the transmission of the nerve impulses from the region to the other cell. The axon is a single extension carries the message to the next neuron‚ which controls all of the nerves. The nerve impulse is response of the neuron. There are 3 classes of neurons: sensory neurons‚ motor neurons‚ and interneurons. Neurons are also called nerve

brain contains an estimated 1011 (100 billion) neurons. Each neuron may communicate with thousands of other neurons in complex information-processing circuits. Recently developed technologies can record brain activity from outside the skull. One technique is functional magnetic resonance imaging (fMRI)‚ which reconstructs a 3-D map of the subject’s brain activity. The results of brain imaging and other research methods show that groups of neurons function in specialized circuits dedicated to different

1.) Name and describe the function of each part of a neuron. What is a neuron? The neurons are the basic elements of our nervous system. You can call them specialized cells in which includes the units of info-development in our brain‚ are very responsible for the perception and the transportation of information. Each part of the neuron has a very important role providing information in the whole body. The most important parts of a neuron are: a cell body‚ dendrites‚ and an axon. • Cell Body‚ also

Nikki Hayes Bonus assignment April 17‚ 2012 Acetylcholine Acetylcholine better known as ACh is a neurotransmitter that is produced by cholinergic neurons. Nerves that rely on Ach are classified as cholinergic nerves. Acetylcholine is found in both the peripheral nervous system and the central nervous system. Acetylcholine can also be found in the autonomic nervous system and is the only neurotransmitter used in motor division of the somatic nervous system. In the peripheral nervous system
