PSU Bio 161 Test 3 Questions And Answers With
Complete Solutions | New Update
synapse - ANSWERS space between neurons, where the conversion from an
electrical signal to a chemical signal occurs
neruotransmitter - ANSWERS chemical messenger released at the end of a
nerve cell
presynaptic cell - ANSWERS neuron that sends message, gives off the electrical
signal
postsynaptic cell - ANSWERS neuron that receives message
voltage-gated calcium channels - ANSWERS A membrane protein forming a
pore that is permeable to Ca2+ ions and gated by depolarization of the
membrane.
EPSP - ANSWERS a.k.a excitatory postsynaptic potential, causes depolarization
of postsynaptic neuron
IPSP - ANSWERS a.k.a. inhibitory postsynaptic potential, causes
hyperpolarization of postsynaptic neuron
, summation - ANSWERS sum of all local potential chances at the synapses of a
postsynaptic cell
frequency of action potentials - ANSWERS interpreted in the brain as the
strength of the stimulus (stronger stimulus=more action potentials)
Forebrain - ANSWERS made up of the cerebrum and diencephalon, integrates
info to help regulate complex organ systems, integrates conscious thought
cerebrum - ANSWERS Largest part of the brain; responsible for voluntary
muscular activity, vision, speech, taste, hearing, thought, and memory.
diencephalon - ANSWERS thalamus, hypothalamus, epithalamus
midbrain - ANSWERS integrates info from special senses and movement
hindbrain - ANSWERS contains cerebellum, pons, and medulla; primitive
responses (heart rate, breath rate)
gyri - ANSWERS ridges of the brain
sulci - ANSWERS valleys of the brain
cerebellum - ANSWERS located at the rear of the brainstem, a large structure
of the hindbrain that controls fine motor skills.
