The action potential travels down:
A. the dendrite.
B. the synapse.
C. the axon.
D. both the dendrite and axon.
The answer is option (C) the axon.
An action potential is a neural impulse. That is an electrical charge which travels down an axon.
The action potential travels down: A. the dendrite. B. the synapse. C. the axon. D. both...
7. Which of the following is conteet? A Synapse Axon-Dendrite-Terminal-Synapse B. Synapse-Dendrite-Axon-Terminal-Synapse C. Synapse-Terminal- Axon-Dendrite-Synapse D. Axon-Synapse-Dendrite Terminal- Axon 8. All experience, thoughts and feelings are electrical activity in some part of the brain True Faise 9. Sentory crossing, such as seeing a sound is called A Synergism B. Synesthesia C. Tolerance D. Tolergism effects 10. Effects of a drug that are not based on its chemical activity alone ure A. Specific B. Combined C. Targeted Nonspecific 11. The point...
While the classic synapse is one between an axon and a dendrite, axons can create synapses with any part of a neuron. The major kinds are axo-somatic (axon synapses with the soma of the post-synaptic neuron), axo-dendritic (the classic synapse), and axo-axonic (creates a synapse with the post-synaptic neurons axon). How do you think location of these synapses would affect the generation of an action potential?
What are the structure of nerve cell, synapse, neurotransmitter, axon, dendrite, receptor, gyri and Sulci?
The action potential travels down the cell's axon to initiate transmitter release at the presynaptic terminal. At the terminal, voltage-gated channels... a. allow potassium to rush into the cell, causing neurotransmitter release b. allow calcium to rush into the cell, causing a direct change in voltage in the next cell c. allow calcium to rush into the cell, causing neurotransmitter release d. allow calcium to rush out of the cell, causing neurotransmitter release
Which of the following parts of a neuron receive and process information? Cell Body Dendrite Synapse Axon Which of the following characteristics is common to oligodendrocytes and Schwann cells? Both from a myelin sheath around a single axon Both provide myelination Both can interact with multiple cells Both are located in the CNS
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...
Propagation of an action potential down an axon is produced by: capacitive depolarization produced by the current lowers the membrane potential regenerative increase in Na+ permeability depolarization due to opening of Na+ channels all of the above
Diagnostic clinical reasoning Action potentials are propagated down the length of an axon via both passive and active membrane properties. The rate at which the action potential travels is variable and depends on axon diameter and myelin. DIAGNOSTIC CLINICAL REASONING 5.2 G.B., Part Il Because of the damage to his myelin, he has sensory and motor impairments in his limbs. G.B.5: Light touch sensation is impaired throughout GB's and face. What types of neurons transmit sensory information from the periphery...
The resting membrane potential of a neuronal axon is -70 mV. When an action potential is triggered, Na+ ions move into the axon, which reverses the voltage, bringing it towards 0 mV. Which of the following is the correct term for this sequence of events? a. Repolarization b. Hyperpolarization c. Depolarization d. Hypopolarization e. Isopolarization
1. The main receptive surface of neuron at a synapse for nerve Impulse transmission is: a. Axon neurotransmitter receptors b. Dendrite neurotransmitter receptors C. Nissl bodies receptors d. Axon terminal receptors 2. Two types of cells in nervous system are: a. Axons & dendrites b. Motor and sensory neurons c. Neurons & neuroglia d. Schwann cells & microglia 3. Myelin is rich in : a. Lipids b. Carbohydrates c. Nucleic acids d. Salts 4. Synaptic knobs are at end of:...
