year notes USABO Exam Questions And Answers axon hillock - ANS the cone-shaped area on the cell body from which the axon originates -trigger zone hyperopia - ANS A condition in which visual images come to a focus behind the retina of the eye and vision is better for distant than for near objects -- called also farsightedness. axon hillock has high concentration of what voltage gated pumps - ANS sodium and potassium how to calculate membrane potential - ANS the outs...

Action potentials are first generated at the axon hillock because this is where a high concentration of _______ are located. a. non-gated K+ channels b. voltage-gated Na+ channels c. transporters d. Na+/K+ pumps - ANSWER b

When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. - ANSWER TRUE Briefly explain why the action potential flows only from the axon hillock to the terminal web. - ANSWER During the course of an action potential there is a refractory period that makes sure the action potential can't trigger backwards by the use of caps on gated sodium channels. The caps close and keeps the action potential flowing in one direction. How do the glial cells (i.e., m...

NSC 3361 Exam 1 Questions and Answers All Correct Sequence of transmission at chemical synapse - Answer-1. Action potential travels down axon to axon terminal. 2. Voltage-gated calcium channels open and Ca2+ enters. 3. Synaptic vesicles fuse with membrane and release transmitter into the cleft. 4. Transmitter binds to post-synaptic receptor, causing EPSP or IPSP. 5. May bind to the presynaptic autoreceptors, decreasing release. 6. Neurotransmitter is inactivated by degradation or reuptak...
