Quick explanation
Describe Pacinian corpuscle and retinal photoreceptor function
- This point belongs to Response and homeostasis official content, especially Nervous coordination.
- You need to be able to describe Pacinian corpuscle and retinal photoreceptor function.
- The key ideas to know are receptor, retina, and Pacinian corpuscle.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Nervous coordination to exam-style questions, flashcards, and revision notes for Response and homeostasis official content.
Quick student answer
What is the primary function of Pacinian corpuscles?
Direct answer
Pacinian corpuscles are mechanoreceptors that primarily detect pressure and vibration.
Key terms
- Pacinian corpuscle: A type of mechanoreceptor that detects pressure and vibration.
- Retinal photoreceptor: A cell in the retina that converts light into electrical signals, including rods and cones.
Common trap
Confusing the functions of different types of receptors: Remember that Pacinian corpuscles specifically detect pressure and vibration, while other receptors may detect touch or temperature.
