Nervous System and Brain Functions

What is the main function of the nervous system?

• To produce hormones that regulate bodily functions.

• To receive stimuli from the environment, process that information, and coordinate responses.

• To transport oxygen and nutrients throughout the body.

• To provide structural support to the body.

What is the role of sensory neurons?

• Sensory neurons relay impulses from sense organs to the brain.

• Sensory neurons transmit signals from the brain to muscles.

• Sensory neurons are responsible for processing emotions.

• Sensory neurons regulate body temperature.

What is an interneuron?

• Interneurons connect sensory and motor neurons and process information within the brain and spinal cord.

• Interneurons are responsible for transmitting signals from the brain to the muscles.

• Interneurons are a type of sensory neuron that detects external stimuli.

• Interneurons are specialized cells that produce hormones in the body.

What is the role of motor neurons?

• Motor neurons transmit impulses from the brain to muscles, causing movement.

• Motor neurons are responsible for processing sensory information.

• Motor neurons help in the formation of memories in the brain.

• Motor neurons regulate the body's temperature.

What are neurons?

• Specialized cells that transmit nerve impulses throughout the body.

• Cells that store energy in the body.

• Cells that produce hormones in the body.

• Cells that protect the body from infections.

What is the importance of vision in animals?

• Vision helps animals navigate their environment, find food, and avoid predators.

• Vision is primarily used for communication between animals.

• Vision is not important for most animals.

• Vision only helps in identifying other animals.

How does the brain process information?

• By interpreting signals received from sensory neurons and coordinating appropriate responses.

• By storing information in long-term memory without any processing.

• By randomly selecting responses based on previous experiences.

• By ignoring sensory input and focusing on internal thoughts.

What is the function of the brainstem?

• It regulates emotions and memory.

• It controls basic life functions such as breathing, heart rate, and blood pressure.

• It processes visual and auditory information.

• It is responsible for higher cognitive functions like reasoning and problem-solving.

What is the role of the cerebellum?

• The cerebellum coordinates muscle movements and maintains balance and posture.

• The cerebellum is responsible for processing visual information.

• The cerebellum regulates emotions and memory.

• The cerebellum controls the body's immune response.

What is a synapse?

• A type of neurotransmitter that carries signals between neurons.

• The small gap between two neurons where communication occurs.

• A structure that protects the neuron from damage.

• A type of brain cell that supports neuron function.
