Divisions of the Nervous System - 🧠 ANSWER ✔✔
Label the structures and supporting cells of a neuron - 🧠 ANSWER ✔✔
Connect the structures and supporting cells of a neuron to its functions - 🧠
ANSWER ✔✔Receptive region when stim is received at dendrites, then
conducting region where signal travel through, the secretory region to
release neurotransmitters
Explain the differences between resting, local, and action potentials. - 🧠
ANSWER ✔✔The resting potential tells about what happens when a
, neuron is at rest. An action potential occurs when a neuron sends
information down an axon, away from the cell body.
a transient depolarizing or hyperpolarizing shift of the membrane potential
in a localized area of the cell. Local potentials result from the current flow
due to localized change in ion channels that alter permeability to one or
more ions.
Describe how neurotransmitters carry messages between neurons - 🧠
ANSWER ✔✔when action potentials reach the end of an axon (the axon
terminals), they stimulate the release of neurotransmitters. These chemical
messengers carry a message from the sending neuron across a synapse to
receptor sites on a receiving neuron.
Predict what will happen when given postsynaptic potentials are received
together - 🧠 ANSWER ✔✔Spatial summation occurs when multiple
presynaptic inputs each stimulate the postsynaptic neuron at the same
time. Both types of summation result in a depolarization of a higher
magnitude that when only on excitatory input occurs
