Questions and Answers (Verified Answers)




What is the major cause of membrane depolarization?

influx of sodium ions

The neuroglia forming the myelin sheath around neuron fibers in the PNS are:

Schwann cells

The resting membrane potential is characterized by

high potassium and protein inside the cell, and high sodium and calcium outside the cell

Inside an activated cell

Na+ and Ca++ are higher in concentration than in the resting state

An action potential

is propagated by opening of voltage-gated sodium channels

What is saltatory conduction in a neuron? Is it fast or slow?

Saltatory conductions describes how an action potential jumps node to node in a myelinated fiber. It is
fast.

The substance released at axonal endings to propagate a excitatory postsynaptic impulse is called a(n)

neurotransmitter

When a postsynaptic neuron receives repeated stimuli in a short time, this causes

temporal stimulation

An excitatory neurotransmitter secreted by motor neurons innervating skeletal muscle is

acetylcholine

A neural circuit with input traveling along several pathways for integration by several CNS systems and
providing several responses is a

parallel processing circuit

Brain wave amplitude

, reflects the number of neurons firing synchronously

What characterizes the fourth stage of sleep in the sleep cycle?

EEG pattern is dominated by delta waves; skeletal muscles are relaxed; arousal difficult

Fact memory

ability to learn specific information

Activation of the reticular activating system results in

wakefulness

Which controls the autonomic nervous system?

hypothalamus

Which stimulates inspiration?

pons apneustic center

Which is innervated by the somatic nervous system

skeletal muscle

The site of origin of the preganglionic fibers of the parasympathetic nervous system is the

brain stem and the sacral region of the spinal cord

All preganglionic axons of the autonomic nervous system release

the same transmitter as the one released by parasympathetic postganglionic axons

Which provides the ultimate control for the sympathetic nervous system?

hypothalamus

Potentially damaging stimuli that result in pain are selectively detected by

nociceptors

Which type of receptors frequency of sensory neuron action potentials increases with the generator
potential and stimulus amplitude?

tonic

Which skin receptors detect texture and vibrations?

Meissner's corpuscles

When a skin area's two-point threshold is large, that skin has

low sensory acuity

How does a gustatory cell respond to sour tastes?
