Nervous System Practice Questions

Front

What are photoreceptors and where are they primarily found?

Back

Photoreceptors are specialized cells that detect light and are primarily found in the retina of the eye.

Front

What are the three main parts of the nervous system?

Back

The three main parts of the nervous system are the brain, spinal cord, and nerves.

Front

What is the function of nociceptors?

Back

Nociceptors are sensory receptors that respond to potentially damaging stimuli, resulting in the sensation of pain.

Front

What does 'Motor Output' refer to in the nervous system?

Back

Motor Output refers to the signals sent from the nervous system to muscles or glands to elicit a response.

Front

How do motor neurons function in a reflex arc?

Back

Motor neurons transmit signals from the spinal cord to the effector (muscle or gland) in a reflex arc.

Front

What is the role of sensory neurons in the nervous system?

Back

Sensory neurons carry signals from sensory receptors to the central nervous system (CNS) for processing.

Front

Define integration in the context of the nervous system.

Back

Integration is the process by which the CNS processes sensory information and determines an appropriate response.

Front

What is the difference between the central nervous system (CNS) and the peripheral nervous system (PNS)?

Back

The CNS consists of the brain and spinal cord, while the PNS includes all the nerves that branch out from the CNS.

Front

What are the main types of neurons in the nervous system?

Back

The main types of neurons are sensory neurons, motor neurons, and interneurons.

Front

What is a reflex arc?

Back

A reflex arc is a neural pathway that controls a reflex action, involving sensory neurons, interneurons, and motor neurons.
