Obturator crest

Obturator crest is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Obturator crest rather than just read about it. In short: The anterior border of the superior pubic ramus presents a sharp margin, the obturator crest, which forms part of the circumference of the obturator foramen superiorly and affords attachment to the obturator membrane. The obturator crest extends from the pubic tubercle to the acetabular notch.

Key takeaways

Obturator crest belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Obturator crest to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Obturator crest from memory before moving on to harder problems.

Reference excerpt

Worked examples

Example 1 — a first encounter with Obturator crest

Start with the simplest possible case. Write down what Obturator crest claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Obturator crest before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Obturator crest ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Obturator crest

In research: Obturator crest appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Obturator crest in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Obturator crest is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bones of the pelvis, Musculoskeletal system stubs, Pubis (bone), so understanding it makes those chapters shorter.
In everyday life: Look for Obturator crest outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
