Marieb Ch7A Nervous System Overview Quiz

What is the main function of the nervous system?

• Transmitting signals and coordinating bodily functions

• Regulating body temperature

• Digesting food and absorbing nutrients

• Producing hormones

Name the two main divisions of the nervous system.

• Upper nervous system and lower nervous system

• Central nervous system (CNS) and peripheral nervous system (PNS)

• Brain and spinal cord

• Somatic nervous system and autonomic nervous system

What are the two types of cells that make up the nervous system?

• Muscle cells and bone cells

• Skin cells and hair cells

• Neurons and glial cells

• Red blood cells and white blood cells

Explain the difference between the central nervous system and the peripheral nervous system.

• The central nervous system is made up of the autonomic and somatic nervous systems, while the peripheral nervous system is made up of the sympathetic and parasympathetic nervous systems.

• The central nervous system is located in the arms and legs, while the peripheral nervous system is in the head and torso.

• The central nervous system consists of the brain and spinal cord, while the peripheral nervous system includes all the nerves outside of the central nervous system.

• The central nervous system is responsible for motor functions, while the peripheral nervous system is responsible for sensory functions.

What is anther name for the sensory division of the nervous system?

• efferent division

• afferent division

• autonomic division

• somatic division

What two systems is the efferent division of the nervous system broken into?

• somatic nervous system

• central nervous system

• autonomic nervous system

• peripheral nervous system

What is the purpose of the autonomic nervous system?

• To control involuntary bodily functions

• To control voluntary bodily functions

• To produce hormones

• To regulate body temperature

Which type of supporting cells are spiderlike phagocytes that monitor the health of nearby neurons and dispose of debris, such as dead brain cells and bacteria?

• microglia

• astrocytes

• ependymal cells

• oligodendrocytes

What are neurotransmitters and what role do they play in the nervous system?

• Enzymes that break down food in the digestive system

• Hormones that regulate blood sugar levels

• Proteins that provide structure to the nervous system

• Chemical messengers that transmit signals and play a crucial role in communication within the nervous system.

How does the nervous system coordinate the body's response to external stimuli?

• Digestion of food in the stomach

• Muscle contraction and relaxation

• Transmission of electrical signals between the brain, spinal cord, and peripheral nerves

• Release of hormones from the endocrine system
