Nervous System is made up of specialized cells called ____________ , neurons or nerve cells, They store information and carry messages within the nervous system and between other body systems, Neuron or nerve cells, Neuron is divided into how many parts?, 3 parts, What are the 3 parts of the neuron?, 1. cell body 2. dendrite 3. axon, What is the main part of the neuron, cell body, The cell body contains ___________, which houses the neuron's genetic information, nucleus, These are the branchlike extensions on the cell body, dendrites, These receive messages from other neurons, dendrites, ________________ travel along the dendrite to the cell body., nerve impulses, True or False. Neurons only have one dendrite, False, True or False. Neurons can have more than one dendrite, True, An _______________ extends from the cell body and often gives rise to many smaller branches before ending at nerve terminals, axon, This carries electrical messages away from the cell body and passes them to other cells, axon, Axons are wrapped with _______________, a fatlike substance that accelerates the transmission of nerve impulse along axons, myelin sheath, True or False. Neurons can be classified based on the direction in which they send information to and from the body, True, What are the 3 sensory neurons?, 1. sensory neuron 2. motor neuron 3. interneuron, This type of Neuron that sends information from the environment toward the brain and spinal cord, sensory neuron, This type of neuron that carries messages away from the brain or spinal cord to your muscles or glands causing them to react or move, motor neuron, This type of neuron that sends information between sensory neurons and motor neurons; most interneurons are located in the CNS, interneuron, Your neurons are like ______ spread all over your body to transmit information. , wires, True or False.
