Front

In the eye, which cells are responsible for grey-scale vision?

Back

Rod cells are responsible for grey-scale vision.

Front

In the eye, which cells are responsible for color vision?

Back

Cone cells are responsible for color vision.

Front

What type of reflexes include the secretion of saliva and changes in pupil size?

Back

Autonomic reflexes include these activities.

Front

What is the correct sequence of events for a nerve impulse?

Back

2. Sodium channels open and sodium ions diffuse in; 1. The membrane becomes depolarized; 4. Potassium channels open and potassium ions diffuse out; 3. The membrane becomes repolarized.

Front

What part of the neuron conducts nerve impulses away from the cell body?

Back

The axon conducts nerve impulses away from the cell body.

Front

Where are the centers for controlling vital activities like heart rate and breathing located?

Back

The centers are located in the medulla oblongata.

Front

What is the function of rod cells in the retina?

Back

Rod cells are responsible for vision in low light conditions and grey-scale vision.

Front

What is the function of cone cells in the retina?

Back

Cone cells are responsible for color vision and function best in bright light.

Front

What is the role of the autonomic nervous system?

Back

The autonomic nervous system controls involuntary bodily functions such as heart rate, digestion, and respiratory rate.

Front

What happens during depolarization of a neuron?

Back

During depolarization, sodium ions enter the neuron, making the inside more positive.
