Functions of the Nervous System

After eating a meal, your stomach stretches and sends signals to your brain. The brain responds by slowing down movement and initiating digestion. What two systems are mainly working together here?

• Nervous and skeletal

• Nervous and muscular

• Nervous and digestive

• Nervous and integumentary

A student notices their heart rate increases when they’re nervous before a presentation. Which systems are interacting in this response?

• Muscular and skeletal

• Nervous and circulatory

• Respiratory and integumentary

• Excretory and digestive

During exercise, the nervous system helps regulate breathing rate and posture. Which two systems are being regulated directly?

• Respiratory and skeletal

• Respiratory and muscular

• Muscular and circulatory

• Endocrine and digestive

The nervous system detects a sudden change in blood pressure and signals the blood vessels to dilate. This is an example of interaction between:

• Nervous and excretory systems

• Nervous and circulatory systems

• Nervous and digestive systems

• Nervous and skeletal systems

Why is the nervous system critical in maintaining homeostasis?

• It transports hormones throughout the body.

• It provides nutrients to cells.

• It detects changes and coordinates appropriate responses.

• It delivers oxygen to tissues.

A person touches a hot stove and quickly pulls their hand away. What body systems are interacting here?

• Nervous and endocrine

• Nervous and skeletal

• Nervous and muscular

• Nervous and circulatory

The hypothalamus helps regulate body temperature by triggering sweating or shivering. Which system works directly with the nervous system here?

• Circulatory

• Digestive

• Muscular

• Integumentary

When someone experiences dehydration, the brain sends a signal to increase thirst. This is an example of:

• Circulatory system control

• Voluntary behavior

• Sensory system error

• Nervous system maintaining internal balance

A person sees a ball flying toward them and catches it. Which best describes this process?

• Only the muscular system is used.

• Only the sensory receptors respond.

• The brain interprets sensory input and triggers a motor response.

• Reflex behavior is executed without brain involvement.

During digestion, which role does the nervous system play?

• Breaking down nutrients

• Absorbing food in the intestines

• Controlling the movement of food through peristalsis

• Secreting bile from the liver
