The Human Nervous System Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What are the two main components of the nervous system?

Central nervous system (CNS) – The spinal cord and the brain.

Peripheral nervous system (PNS) – Carries information to and from the CNS.

What are neurones and what is their function?

Neurones (nerve cells) are specialised cells adapted to carry electrical impulses throughout the body.

How are neurones connected and what allows them to communicate?

Neurones are connected by a network through dendrites and axons, which are insulated by the myelin sheath with nodes that allow them to communicate.

What is the sequence of the path through the nervous system?

Stimulus → receptor → coordinator (CNS) → effector → response.

What is the role of receptors in the nervous system?

Receptors detect stimuli and send electrical impulses along neurones to the central nervous system for coordination.

What are effectors and what do they do?

Effectors are parts of the body, such as muscles or glands, that produce a response to a stimulus.
