Supraglenoid tubercle

Supraglenoid tubercle 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 Supraglenoid tubercle rather than just read about it. In short: The supraglenoid tubercle is a region of the scapula from which the long head of the biceps brachii muscle originates. It is a small, rough projection superior to the glenoid cavity near the base of the coracoid process.

Key takeaways

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

Reference excerpt

The supraglenoid tubercle is a region of the scapula from which the long head of the biceps brachii muscle originates. It is a small, rough projection superior to the glenoid cavity near the base of the coracoid process. The term supraglenoid is from the Latin supra, meaning above, and glenoid, meaning socket or cavity.

Clinical relevance

Biceps tendonitis Biceps tendonitis originates on the long head of the biceps brachii at the supraglenoid tubercle in 30% of cases. The main symptom is generally anterior biceps instability, but the disease can also be characterized by chronic anterior shoulder pain which radiates towards the lateral part of the elbow. In cases of biceps tendinitis, steroids can be injected fluoroscopically at the supraglenoid tubercle to reduce pain associated with the pathology.

Avulsion The supraglenoid tubercle ossifies separately from the rest of the scapula, so may not be as strong as the rest of the bone. It can be pulled off (avulsed), often after an excessively strong contraction of the biceps brachii. This may also cause a fracture of the surrounding parts of the scapula, particularly the glenoid cavity. This may also occur in horses. This type of bone fracture is quite rare.

Worked examples

Example 1 — a first encounter with Supraglenoid tubercle

Start with the simplest possible case. Write down what Supraglenoid tubercle 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 Supraglenoid tubercle 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 Supraglenoid tubercle 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 Supraglenoid tubercle

In research: Supraglenoid tubercle 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 Supraglenoid tubercle 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: Supraglenoid tubercle is common in secondary-school and first-year university syllabi. It links to neighbouring topics Musculoskeletal system stubs, Scapula, so understanding it makes those chapters shorter.
In everyday life: Look for Supraglenoid tubercle 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.
