Describe the events at the axon terminal that cause one neuron to release a neurotransmitter onto another. - The action potential travels down the axon and gets to the axon terminal, which causes calcium to enter the axon terinal, which causes the release of the neurotransmitter by exocytosis into the synaptic cleft. The post synaptic neuron, dendrite opens voltage gated channels and allow Na+ in and K+ out. A hypothyroid individual shows no increase in metabolic rate when injected with TSH...

A nurse conducting a physical assessment is observing the client's balance and performing tests to determine the client's sense of equilibrium. Which cranial nerve is the nurse assessing? 1. Cranial nerve II 2. Cranial nerve IX 3. Cranial nerve VII 4. Cranial nerve VIII - Answer 4. Cranial nerve VIII Cranial nerve VIII is the acoustic nerve. Hearing tests are performed to assess the cochlear portion of this nerve. Tests to assess equilibrium, such as observation of the client's bal...
