Answer Thi Q. thank You The Nervous System edit) 1. The junction between one neuron and the next, or between a neuron and an effector is called: A) A synapse 8) A dendrite C) A neuotransmiter D ) A ventricle E) None of the above 2. A fast excitatory synapses follows this order A) (1) neurotransmiter released (2) diftused across the synaptic cleft to a receptor protein (3) binding of the transmitter opens pores in the ion channels and positive ions move in. B) (1) neurotransmitter released (2) diffused across the synaptic cleft to a receptor protein (3) binding of the transmitter opens pores in the ion channels and negative ions move in. С 1 neurotransmitter released 2, diffused across the synapte den to a receptor amino acid 3 b ing or the trans eer opens pores n the ion e annes and positive ons move n. D 1) diffused across the synaptic cleft to a receptor protein 2 neurotransmetter released ③ binding of the transmitter opens poes in the ion channels and poeme ont move in. E) None of the above 3. Resting potential is A) excess positive ions accumulate inside the plasma membrane B) excess negative ions acoumulate inside the plasma membrane C ) excess positive ions accumulate outside the plasma membrane D) both b & E) both a & 4. Sensory neurons have: A) A short dendrite and a long axon B ) A short dendrite and a short axon C) A long dendrite and a short axon D ) A long dendrite and a long axon E) Their axons and dendrites may be either long or shont 5blocks Acetylcholine receptor sites causing muscle relaxation. A) Novocain B) curare C ) Nicotine D) Nerve gases 6. Transmission across a synapse is dependent on the release of B ) synaptic vesicle C) neurons D ) receptor proteins 7. Motor neurons take messagos A) from the muscle fiber to the central nervous system B) away from the central nervous system to the central nervous system C) that are classified D ) away from the central nervous system to muscle fiber 8. The medulla oblongata helps to regulate which of the following: A) Breathing 8) Heartbeat C) Sneezing D ) Vomiting E ) All of the above 9. The nervous systems main components are what? A ) The Synapses and Sprinal cord B) The neurons and the synapses C ) The brain and the neurons D )The brain and the spinal oord 10. Explain what LTP does to enhance communication between two neurons, on the postsynaptic end More receptors, such as AMPA recoptors, are aoded and existing ones are sensized via phosphorylation Pendntic spine number and surface area is increased as wel 11. Explain what LTP does to enhance communication between two neurons, on the presynaptic end If the retrograde messenger theory is correct, presynaptic cells participate in the onhancement by increasing the probability of synaptic vesicle release. (Please remember the retrograde messenger is theoretical, I just thought it should be included here) The Nervous System edit) 1.
