HintAnswer
the _____ carries the action potential to the synapse
in order to create an action potential, the stimulus must be greater than the
myelin is produced by
responsible for contracting force in muscle as well as phagocytosis and cytokinesis
the_________ receives a signal to be transmitted in the neuron
neuronal cell bodies appear
when the voltage gated potassium channels open leads to
microtubules are made of
detects sound in the ear
unidirectional slower synapse
cells in the eye that dont distinguish color
The ____________ can be further subdivided into the sympathetic nervous system and the parasympathetic nervous system
fight or flight
receive signals from a receptor that interacts with the environment
The ____________ can be further subdivided into the somatic nervous system and the autonomic nervous system
when the action potential arrives at the synapse, _______ ions are released
transfer signals from neuron to neuron
major portion of cilia and flagella arranged in a 9+2
another molecule within the cell that gets activated by a neurotransmitter to make changes, e.g. a G-protein
short period of time in which no stimulus will create another action potential
HintAnswer
Brain and spinal cord
rest and digest
myelinated axons appear
cells in the eye that can distinguish color
sensory neruon cell bodies are located in the
neurotransmitter used by all preganglionic neurons in theANS and by postganglionic neurons in the parasympathetic system
junctions that are small tunnels connecting cells
neural impulses are transmitted from one cell to another via a
opening of voltage gated sodium channels leads to
tiny gaps between myelin are called
where is the action potential generated
responsible for higher level thoughts and consciousness
The sodium potassium pump moves
postganglionic neurons of the sympathetic system use
microfilaments are made of
cellular junction that acts as a fluid barrier around cells
junction that joins two cells at a signle point
a synapse composed of gap junctions, bidirectional and faster
carry signals to a muscle or gland
detects orientation and movement of the head
