Neuron Transmission

• Response time of a neural pathway is considered.

  The human body is a nice, warm, constant temperature but if the body gets really cold signal transmission slows down. A few things outside the neuron that could have an effect are other neurons.

• Chemical and Electrical synapses properties in the CNS.

  In this type of synapse, information is sent unidirectionally from the pre-synaptic neuron to the post-synaptic neuron, and those cells do not touch.

• Neuron and synapse structure and function

  It serves to allow the message to jump from 'sausage' to 'sausage', allowing much faster transmission of the message than would occur if it had to travel along the axon itself. Most neurons have a myelin coating.

• Specific ascending pathways

  The cell body of a second order neuron is located in the nucleus cuneatus or nucleus gracilis. The axon of the second order neuron crosses to the opposite side of the medulla and enters the medial lemniscus.

• Neuroanatomical Structure & Function, Synapses and Addiction

  SYNAPSES: The functional junction between the dentritic region of one neuron and the axon of another nerve cell (neuron) is known as synapse. It helps in passing nerve impulses in one direction across the neuron.

• How do postsynaptic potentials affect behavior

  For example, too much transmission may occur when the neuron fires in the absence of a stimulus or when too many neurotransmitters attach to the receptors on the far side of the synapse (the postsynaptic receptors).

• Myelin and the Myelination Process in CNS and PNS

  It is at these nodes that the action potential jumps along the axon making transmission velocities very high. CNS: Oligodendrocytes participate in myelination in the CNS.

• Process of Neurotransmitter Release

  The Neuron The neuron is a nerve cell, an electrically excitable basic unit of animals that includes us, humans.
