a synapse composed of gap junctions, bidirectional and faster
tiny gaps between myelin are called
receive signals from a receptor that interacts with the environment
fight or flight
myelin is produced by
sensory neruon cell bodies are located in the
when the action potential arrives at the synapse, _______ ions are released
detects sound in the ear
The ____________ can be further subdivided into the somatic nervous system and the autonomic nervous system
postganglionic neurons of the sympathetic system use
detects orientation and movement of the head
cells in the eye that can distinguish color
short period of time in which no stimulus will create another action potential
another molecule within the cell that gets activated by a neurotransmitter to make changes, e.g. a G-protein
cells in the eye that dont distinguish color
unidirectional slower synapse
neural impulses are transmitted from one cell to another via a
neurotransmitter used by all preganglionic neurons in theANS and by postganglionic neurons in the parasympathetic system
transfer signals from neuron to neuron
opening of voltage gated sodium channels leads to
