couple of centuries our knowledge of the nervous system has increased rapidly. As there were developments in the technology and techniques that are used to study the nervous system. Previous to the discovery of the neuron there were many rival theories about the arrangement of the nervous system. The two leading scientific groups leading the research labelled themselves as ‘The Reticularists’ and ‘The Neuronists’. The Reticularists theory was that ‘the nervous system consisted of a large network of tissue

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 of a feedback system and describe each briefly. A sensor that detects a change in

In addition‚ it will show how the primary biological foundations of psychology are linked to behavior such as‚ brain‚ central nervous system‚ peripheral nervous System‚ and genetics/evolution. Behavioral Theory Behavioral psychology‚ also known as behaviorism‚ is a learning theory established on the notion that behaviors are gathered by conditioning. Conditioning develops from influenced of the

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.

1. What is a neuron? o The individual nerve cell‚ comprised of the axon‚ dendrites‚ and cell body. 2. How many neurons in the nervous system? o 86 billion 3. Function of cell body‚ dendrites‚ and axons. o Cell body: Contains the nucleus and other major components. o Dendrites: Branch out from the cell body and receive messages from other neurons. o Axons: Carries messages away from the cell body to the dendrites. 4. Define polarization/depolarization. o Polarization: Resting state of neuron

useful information about our body and what it is made up of and how it works. The nervous system which is made up of the sensory and control apparatus consisting of a network of nerve cells that control our body functions. There are two main nervous systems: Central Nervous System and the Peripheral Nervous system. Your central nervous system (CNS) consists of your brain and spinal cord. Where as the Peripheral Nervous system (PNS) consists of sensory neurons running from stimulus receptors that inform

particular body system. I decided to focus on the neurological system and to do my research on cerebral palsy. The nervous system is a delicate body system made up of many parts and has many functions. The nervous system has three main functions- sensory‚ integration‚ as well as motor. There are two components or the nervous system (the central and peripheral nervous system) as well as two subdivisions (the autonomic or involuntary and the somatic or voluntary nervous system) that are complex

1.An extensive network of specialized cells that carry information to and from all parts of the body is called the nervous system. 2.The basic cell that makes up the nervous system and which receives and sends messages within that system is called a neuron. 3.The long tube-like structure that carries the neural message to other cells on the neuron is the axon. 4.On a neuron‚ the branch-like structures that receive messages from other neurons are the dendrites. 5.
