Quick explanation
Explain how ciliary muscles and suspensory ligaments change the shape of the lens during accommodation
- This point belongs to The human nervous system, especially The eye (biology only).
- You need to be able to explain how ciliary muscles and suspensory ligaments change the shape of the lens during accommodation.
- The key ideas to know are lens, accommodation, and suspensory ligaments.
- 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 The eye (biology only) to exam-style questions, flashcards, and revision notes for The human nervous system.
Quick student answer
How do you explain ciliary muscles and suspensory ligaments change the shape of the lens during accommodation?
Direct answer
In Biology, this page helps you answer questions about ciliary muscles and suspensory ligaments change the shape of the lens during accommodation within The human nervous system. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are ciliary muscles and suspensory ligaments.
Key terms
- ciliary muscles: Muscles that control the shape of the lens during accommodation by contracting or relaxing.
- suspensory ligaments: Fibrous strands that connect the ciliary muscles to the lens, helping to change its shape for focusing.
Common trap
Ciliary Muscles and Suspensory Ligaments Function: Remember that when focusing on near objects, ciliary muscles contract, causing the lens to become thicker, while suspensory ligaments loosen. For distant objects, ciliary muscles relax and suspensory ligaments tighten, making the lens thinner.
