|what are neurons||neurons are specialized cells that transmit nerve impulses|
|Cells of the nervous system are known as?||nerve cells or neurons|
|What are nerve cells or neurons specialized for?||They are specialized to carry messages through electrochemical processes|
|The human brain has approximately how many nerve cells or neurons?||approximately 100 billion|
|What is the size of neurons?||some neurons are 4 micros wide, and the bigger neurons are 100 microns wide|
|Neurons are surrounded by a _______||cell membrane|
|Neurons have a _________ that holds the genes||neuron|
|Neurons have specialized cells called ________ that bring electrical signals to the cell body||dendrites|
|How do neurons communicate with each other?||Through electrochemical process|
|What are the two competing views on neurons?||The nervous system as a reticulum and the neuron doctrine|
|what is the view of the neuron doctrine?||the neuron doctrine regards each neuron as an individual component that communicates with the target cell through contiguity rather than continuity|
|what does the proponents of the reticular theory believe?||they believe that neurons are physically continuous with one another forming an interrupted notwork|
|Who proposed the theory about neural circuit organization?||Santiago Ramon|
|What does the functional polarity theory state?||it states that information flows in one direction through most neurons|
|The main part of a neuron is called?||soma or cell body|
|At the end of the axon is the _____||axon ending|
|what is between the axon ending and the dendrite of the next neuron||a synapse or synaptic gap or synaptic cleft|
|what are node of Ranvier||short lengths where the myelin sheath is interrupted and and axonal membrane is exposed|
|what are myelin sheath||myelin sheath is the insulating covering around the axon|
|what is a bipolar neuron||it is a neuron that has two neurites|
|Give an example of bipolar neuron||retinal cells and olfactory epithelium cells|
|what is a unipolar neuron||it is a neuron that has one neurite|
|what is a multipolar neuron||it is a neuron that has three or more neurites, the most common type of neuron|
|Give an example of multiple neurons||spinal neurons, pyramidal neurons, purkinje cells|
|what is a neurotransmitter||it is a chemical that is stored in the synaptic versticles|
|what are pseudounipolar cells?||Pseudounipolar cells are cells that have two axons rather that an axon and dendrite. One axon extend to spinal cord and the other to the skin or muscle|
|Give an example of pseudounipolar cells||dorsal root ganglion cells|
|What are the parts of a neuron?||dendrite, axon, cell body|
|An axon conducts nerve impulses _____ from the cell body||away from the cell body|
|what are sensory neurons?||sensory neurons are neurons that detect the environment|
|what are the major selective advantages provided by sensory neurons?||Increase stimulus sensitivity.Faster effector cell response. Stronger behavioral response|
|How does sensory neurons provide stronger behavioral response?||Multiple effector cells are influenced|
|How do sensory neurons transmit their impulses?||sensory neurons transmit their information towards the central nervous system. From dendrites to axons to CNS|
|what are neurons that transmit sensory information called?||afferent neurons|
|what is the function of afferent neurons?||afferent neurons transmit information from sensory organs or tissues to the CNS or brain|
|What is the function of Efferent neurons?||Efferent neurons transmit information from CNS to other parts of the body|
|what are interneurons?||Interneurons connect other neurons allowing for effective communication between neurons|
|what is the function of motor neurons?||motor neurons directly or indirectly control the contraction and relaxation of muscles|
|Motor neurons are also called?||motorneurons or efferent neurons|
|What is the function of the efferent neurons?||efferent neurons carry information from the CNS to muscle and other systems|
|Motor neurons carry electrical signals to ______||muscle|
|where are interneurons found?||Interneurons are found in the spinal cord and the brain|
|Interneurons are also called _____||associated neurons, relay neurons, connector neurons, local circuit neurons|
|what are interneurons?||Interneurons are neurons that form connections between other neurons|
