Lesson Quiz Worksheet 26.1

Light, heat, and sound are examples of

• responses

• stimuli

• environments

Stimuli triggers signals in specialized cells called

• sensory neurons

• interneurons

• motor neurons

• glial cells

Signals coming from the sensory neurons are then passed on to the

• sensory neurons

• motor neurons

• glial cells

• interneurons

As signals are passed from the interneuron they are then passed to the

• motor neurons

• sensory neurons

• interneurons

• glial cells

Motor neurons enact a ______ by coordinating muscle movement.

• stimulas

• response

• dormancy

A small collection of interneurons, found in many invertebrates.

• cerebellum

• cerebrum

• ganglia

• motor neuron

• sensory neuron

The "thinking" region of the brain.

• cerebellum

• cerebrum

• ganglia

• motor neuron

• sensory neuron

The region of the brain that coordinates muscle movement.

• cerebellum

• cerebrum

• ganglia

• motor neuron

Brianna observes her pet cat. When the cat sees a moth flitting along a window pane, the cat attempts to bat down the moth with its paw.

What best describes the actions of the nervous system of the cat in this example?

• a stimulus without a response, and involving no other body systems

• a response without a stimulus, and coordinated with the muscular system

• a response to a stimulus that involves no other body systems

• a response to a stimulus that is coordinated with the muscular system

Darla is comparing the nervous systems of three animals: a jellyfish, which is a cnidarian; a grasshopper, which is an arthopod; and a mouse, which is a mammal. Which feature of the nervous system is different among the three animals?

• the degree of specialization among neurons, such as the formation of ganglia and a brain

• the presence of sensory neuron, interneurons, and motor neurons

• the use of the nervous system to respond to stimuli, such as a touch or odor

• the use of the nervous system to control muscels and other body systems
