change in length of the muscle is called a(n) ____________ contraction.
Question: Blood-brain Barrier - CORRECT ANSWER✔✔The supportive glial cells known as astrocytes
participate along with blood vessels to form a permeability barrier in the CNS, known as the
_____________ barrier.
Question: Threshold - CORRECT ANSWER✔✔If the local potential change at the axon hillock is high
enough, above ____________ value, the opening of more sodium channels will be triggered and an
action potential generated.
Question: Axon Hillock - CORRECT ANSWER✔✔The __________________ region of the neuron is found
at the junction where the axon leaves the cell body. It determines whether an action potential will be
sent down the axon.
Question: Brainstem - CORRECT ANSWER✔✔The _______________ connects the spinal cord to the
brain; it contains the medulla oblongata, pons, and midbrain and is involved in control of heart rate,
