GCSE Biology - Nervous System and Reflex Arc #58

The video explains how different parts of the body communicate through the nervous and endocrine systems. It focuses on the nervous system, detailing the structure and function of neurons, synapses, and the central nervous system. The video also covers reflex arcs, highlighting their role in rapid, automatic responses to stimuli.

What is the primary function of a nerve cell?

• To store energy

• To carry electrical impulses

• To produce hormones

• To digest food

Which part of the nervous system is responsible for processing sensory information?

• Peripheral nervous system

• Endocrine system

• Central nervous system

• Digestive system

What type of neuron carries information from receptors to the central nervous system?

• Interneuron

• Sensory neuron

• Relay neuron

• Motor neuron

What is a reflex arc?

• A method of hormone release

• A pathway for conscious thought

• A nerve pathway for unconscious reflexes

• A type of muscle contraction

In a reflex action, what role does the relay neuron play?

• It detects the stimulus

• It carries the impulse to the brain

• It transfers the impulse within the spinal cord

• It contracts the muscle
