Exam 11: Introduction to the Nervous System Nervous Tissue

Ciliated ependymal cells:

Where are neuronal pools located?

The influx of positive charges makes the membrane potential more positive and is known as:

Receptors on a postsynaptic CNS neuron bind glutamate.Describe how the postsynaptic neuron responds.

What type of ion channel in neurons is always open?

A series of measurements with a voltmeter show a neuron's membrane potential becoming more negative,from - 70 mV to - 85 mV.This neuron is experiencing a:

Which number on the graph represents when voltage-gated sodium channels are open?

What is more likely to promote an action potential?

Neurons are responsible for sending and receiving signals referred to as action potentials while neuroglial cells serve a variety of supportive functions.

During depolarization,the membrane potential becomes more positive.

Which type of fiber has the largest diameter?

What is the most metabolically active part of a neuron?

The presence of a synaptic cleft between cells is characteristic of:

Which of the following is NOT a function of neurons?

The conducting region of the neuron is the:

Using the information provided in this graph,which statement best summarizes the activity in this neuron?

Neuronal pools are collections of:

Describe the type of neural circuit that controls skeletal muscle movement.

What type of synapse must have receptors to transmit signals?

Discuss the two main factors to influence conduction speed of an action potential.
