Question

What are the transport proteins channels that are present in a neuron that trigger action potentials? A) Na/K pump B) Calcium pump C) Glucose transporter D) Acqauporin E) A and B AB) C and D Most of the organelles in a neuron are located in the A) dendritic region. B) axon hillock. C) axon D) cell body. E) axon terminals The steps below refer to various stages in transmission at a chemical synapse: 1. Neurotransmitter binds with receptors associated with the postsynaptic membrane. 2. Calcium ions rush into neuron's cytoplasm. 3. An action potential depolarizes the membrane of the axon terminal. 4. The ligand-gated ion channels open. 5. The synaptic vesicles release neurotransmitter into the synaptic cleft. Which sequence of events is correct? A) 1 rightarrow 2 rightarrow 3 rightarrow 4 rightarrow 5 B) 2 rightarrow 3 rightarrow 5 rightarrow 4 rightarrow 1 C) 3 rightarrow 2 rightarrow 5 rightarrow 1 rightarrow 4 D) 4 rightarrow 3 rightarrow 1 rightarrow 2 rightarrow 5 E) 5 rightarrow 1 rightarrow 2 rightarrow 4 rightarrow 3 The three main anatomical and functional divisions of the brain are the A) forebrain, midbrain, hindbrain B) frontal, parietal, occipital C) cerebellum, medulla oblongata, pons D) ventricles, meninges, nerve tracts E) hypothalamus, thalamus, pituitary The left and right sides of the cerebrum are Interconnected by the A) pons B) medulla oblongata C) corpus callosum D) thalamus E) cerebral cortex Receptors for fast pain A) transmit action potentials to the brain along the same neurons used by spinal neurons.
