a) axon b) axon hillock c) dendrites d) soma Which part of a neuron receives stimulation from its environment or from another neuron? a. myelin b. dendrite c. axon d. terminal button What functional class of neuron carries impulses away from the CNS to muscles or glands? What is ...
What is the function of dendrites in a neuron? What initiates an action potential on a muscle cell? Describe an action potential and what it causes at the axon terminal. 1. Explain how graded potentials and action potentials are different. 2. On which part of...
In turn these alterations are summed at the nerve cell's axon hillock and, if above a threshold, yield an action potential spike in the axon of the downstream neuron. If quantum measurement is necessary for experiencing qualia, then anesthetics may act by "freezing" post synaptic ...
A neuron is a cell of the nervous system that is electrically excitable. Neurons have a very specialized cell shape, including a central cell body (or perikaryon), multiple short cell extensions called dendrites, a single long cell extension called the axon, and a swellin...
Axon hillock. c. Dendrites. d. Soma. Describe the function of the following structures of a neuron: a. Axon. b. Dendrite. c. Cell body. Which part of a neuron conducts an impulse toward the soma? What are the three basic parts of neurons? A neuron has three ...
What happens on the neuron level when you forget something? What is the function of neurotransmitters? If it helps, think about the neurotransmitter, acetylcholine. Their function is to: A. be released from the end of the axon (the axon bulb) to move across the gap/s...
What does myelin do for neurons? A. Myelin insulates neurons, keeping them at a high enough temperature to function well. B. Myelin prevents the conduction of electricity from the axon hillock to the axon terminal. C. Myelin traps sodium ions in the ax ...
Question: What is the main functional unit of the nervous system? a. Neuroglia b. Neuroblast c. Neurotransmitter d. Neuron The Nervous System The nervous system is a system in the human body which is highly complex and divided into two main portions wh...
What is the basic unit of the nervous system? a. the brain b. the neuron c. the nerve d. the nerve impulse On which part of the neuron Na+ voltage-gated channels are numerous? a. Axon hillock b. Dendrites c. Axonal terminal d. Soma e. None of the choices ...
Which structure carries incoming impulses towards the nerve cell body? A. Axon hillock. B. Axon. C. Dendrite. D. Synaptic knobs. Which structure is not part of a neuron? A. soma B. glial C. dendrite D. axon What cells form the myelin sheath of the peripheral nervous system?
