Nervous System Test

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

• axon

• synapse

• dendrite

• nucleus

A motor neuron sends impulses

• from the brain to a muscle or gland

• from the brain to a sensory neuron

• from the muscle to an interneuron

• from a sensory neuron to another sensory neuron

Afferent pathways carry impulses from the appendicular skeleton to the brain.  Which of the following would be considered the start of­ an afferent pathway?

• Motor neurons connected to the biceps

• Interneurons deep inside the brain and spinal cord

• Motor neurons in the quadriceps

• Sensory neurons in the dermis of the fingers.

The brain and spinal cord make up the

During a biology class, Olivia asked, "What are the two main divisions of the nervous system?"

• Central and Peripheral Nervous Systems

• Autonomic and Somatic Nervous Systems

• Sympathetic and Parasympathetic Nervous Systems

• Sensory and Motor Nervous Systems

Answer explanation

The two main divisions of the nervous system are the Central Nervous System (CNS), which includes the brain and spinal cord, and the Peripheral Nervous System (PNS), which connects the CNS to the rest of the body.

After integration and processing in the brain, impulses travel down the spinal cord and to the muscles via ________ neurons

• sensory

• motor

• sympathetic

• cerebral

This part of the neuron receives electrical impulses from other neurons.

• axon

• dendrite

• myelin sheath

• nucleus

After eating a hefty Thanksgiving dinner, you sit down with your family to watch the Egg Bowl. The Egg Bowl is the annual college football game between Ole Miss and Mississippi State. You hunker down on the couch with your second piece of pecan pie and think "Dang! my __________________ must be really active right now!"

• Sympathetic nervous system

• Parasympathetic nervous system

• Gobble Gobble

• How is Ms. State allowed to ring cowbells in their stadium when the NCAA has a "no artificial noisemaker" policy. This is not the answer, but it remains a valid point.

Which of the following bodily actions is controlled by the somatic nervous system?
