Chapter 3. Module 3.1 the concept of the Synapse

Question 0

Reflex arc

Answer 0

The circuit from sensory neuron to muscle response

Question 1

Synapse

Answer 1

A specialized gap between neurons

Question 2

Temporal summation

Answer 2

Repeatitive stimuli within a brief time have a cumulative effect

Question 3

Unlike action potentials, which are always depolarizations, graded potentials may be either depolarizations (excitatory) or Hyperpolarization ( inhibitory)

Answer 3

..

Question 4

A graded depolarization is known as

Answer 4

Excitatory post synaptic potential (EPSP)

Unlike an action potential, an EPSP decays over time and space; that is, it’s magnitude fades rapidly

Question 5

Spatial summation

Answer 5

Several synaptic inputs originating from separate locations combine their effects on a neuron

Question 6

Inhibitory postsynaptic potential IPSP

Answer 6

Temporary Hyperpolarization of a membrane

Increases the negative charge within the cell

Question 7

Spontaneous firing rate

Answer 7

A periodic production of action potentials even without synaptic input
