responsible for higher level thoughts and consciousness
neural impulses are transmitted from one cell to another via a
a synapse composed of gap junctions, bidirectional and faster
neurotransmitter used by all preganglionic neurons in theANS and by postganglionic neurons in the parasympathetic system
myelin is produced by
short period of time in which no stimulus will create another action potential
carry signals to a muscle or gland
microfilaments are made of
detects orientation and movement of the head
rest and digest
junctions that are small tunnels connecting cells
neuronal cell bodies appear
sensory neruon cell bodies are located in the
transfer signals from neuron to neuron
