Exploring the Nervous System: Key Concepts and Functions

This video provides an overview of the nervous system, explaining its role in controlling daily activities through electrical signals. It divides the system into the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which connects the central system to the rest of the body. The peripheral system is further divided into the somatic system, controlling voluntary movements, and the autonomic system, managing involuntary processes like heart rate and digestion.

What is the primary function of the nervous system?

• To filter waste from the body

• To pump blood

• To digest food

• To control daily activities by sending electrical signals

Which two main groups is the nervous system divided into?

• Somatic and Autonomic

• Central and Peripheral

• Sympathetic and Parasympathetic

• Brain and Spinal Cord

What does the central nervous system consist of?

• Heart and Lungs

• Nerves and Muscles

• Skin and Bones

• Brain and Spinal Cord

What is the role of the peripheral nervous system?

• To connect the central nervous system to the limbs and organs

• To control digestion

• To filter waste from the body

• To regulate blood pressure

Which system controls voluntary muscle movements?

• Somatic Nervous System

• Autonomic Nervous System

• Sympathetic Nervous System

• Parasympathetic Nervous System

What do sensory neurons do?

• Control digestion

• Regulate heart rate

• Carry information from the nerves to the central nervous system

• Carry information from the brain to the muscles

Which system controls internal body processes like blood pressure and breathing?

• Autonomic Nervous System

• Somatic Nervous System

• Peripheral Nervous System

• Central Nervous System

What does the sympathetic nervous system do during emergencies?

• Regulates digestion

• Slows down the heart rate

• Controls voluntary movements

• Springs into action

When does the parasympathetic nervous system work?

• When you are running

• When you are eating

• During emergencies

• When the body is at rest

How do the sympathetic and parasympathetic systems often work?

• Independently

• In opposite ways

• Together

• Randomly
