A&P: Nerve Pathways & Reflexes

Front

The nervous system processes information in which of the following general ways?

Back

Through sensory input, integration, and motor output

Front

Nerves are classified based on their function and structure. Which of the following is a correct classification of nerves? Sensory, Motor, and Mixed, Central, Peripheral, and Autonomic, Cranial, Spinal, and Visceral, Somatic, Autonomic, and Enteric

Back

Sensory, Motor, and Mixed

Front

Which of the following best describes the function of each part of a reflex arc? Options: Sensory neuron transmits impulses to the brain, motor neuron carries impulses to the muscles, and interneuron connects sensory and motor neurons.; Motor neuron transmits impulses to the brain, sensory neuron carries impulses to the muscles, and interneuron connects motor and sensory neurons.; Interneuron transmits impulses to the brain, sensory neuron carries impulses to the muscles, and motor neuron connects sensory and interneurons.; Sensory neuron transmits impulses to the muscles, motor neuron carries impulses to the brain, and interneuron connects motor and sensory neurons.

Back

Sensory neuron transmits impulses to the brain, motor neuron carries impulses to the muscles, and interneuron connects sensory and motor neurons.

Front

What is impulse processing dependent on?

Back

The organization of neurons in the brain and spinal cord

Front

Fill in the blank: Neurons in the CNS are organized into _______ with varying numbers of cells that work together.

Back

neuronal pools

Front

What effects can neuronal pools have on other pools or peripheral effectors?

Back

Both excitatory and inhibitory

Front

If the net input is excitatory but does not sum to the threshold potential, what will happen?

Back

There will be no nerve impulse.

Front

What is facilitation in the context of impulse processing?

Back

Facilitation is the increase release of neurotransmitter in response to a stimulus.

Front

Facilitation occurs in an excitatory presynaptic neuron upon repeated ________.

Back

stimulation

Front

Convergence in the context of impulse processing refers to:

Back

The merging of multiple signals into a single response.
