Vertical muscle of tongue

Vertical muscle of tongue 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 Vertical muscle of tongue rather than just read about it. In short: The vertical muscle of the tongue is an intrinsic muscle of the tongue. Its fibers extend from the upper to the under surface of the tongue.

Key takeaways

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

Reference excerpt

The vertical muscle of the tongue is an intrinsic muscle of the tongue. Its fibers extend from the upper to the under surface of the tongue. It is innervated by the hypoglossal nerve (cranial nerve XII). Its contraction flattens, widens and elongates the tongue.

Anatomy The vertical muscle of the tongue is an intrinsic muscle of the tongue. It is found only at the borders of the forepart of the tongue.

Structure Fibres of the vertical muscle of the tongue are arranged in an almost vertical direction, and intersect the transversely oriented fibres of the transverse muscle of tongue. Fibers of the vertical muscle of the tongue extend from the upper to the under surface of the tongue.

Innervation The vertical of the tongue is innervated by the hypoglossal nerve (CN XII).

Function Contraction of the vertical muscle of the tongue flattens, widens and elongates the tongue.

Worked examples

Example 1 — a first encounter with Vertical muscle of tongue

Start with the simplest possible case. Write down what Vertical muscle of tongue 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 Vertical muscle of tongue 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 Vertical muscle of tongue 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 Vertical muscle of tongue

In research: Vertical muscle of tongue 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 Vertical muscle of tongue 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: Vertical muscle of tongue is common in secondary-school and first-year university syllabi. It links to neighbouring topics Muscle stubs, Muscles of the head and neck, Tongue, so understanding it makes those chapters shorter.
In everyday life: Look for Vertical muscle of tongue 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.
