Inferior longitudinal muscle of tongue

Inferior longitudinal 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 Inferior longitudinal muscle of tongue rather than just read about it. In short: The inferior longitudinal muscle of tongue is an intrinsic muscle of the tongue. It is situated on the under surface of the tongue between the genioglossus and hyoglossus.

Key takeaways

Inferior longitudinal 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 Inferior longitudinal muscle of tongue to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

The inferior longitudinal muscle of tongue is an intrinsic muscle of the tongue. It is situated on the under surface of the tongue between the genioglossus and hyoglossus. It is innervated by the hypoglossal nerve (cranial nerve XII). Its contraction shortens and thickens the tongue.

Structure The inferior longitudinal muscle of the tongue is an intrinsic muscle of the tongue. It is thin and oval in cross-section. It is situated between the paramedian septum, and the lateral septum. It extends from the root to the apex of the tongue. Posteriorly, some of its fibers attach onto the body of the hyoid bone. Anteriorly, its fibres blend with those of the styloglossus, hyoglossus, and genioglossus to form the ventral area of the tip of the tongue.

Innervation The inferior longitudinal muscle of the tongue is supplied by the hypoglossal nerve (CN XII).

Function Contraciton of the inferior longitudinal muscle of the tongue shortens and thickens the tongue.

Worked examples

Example 1 — a first encounter with Inferior longitudinal muscle of tongue

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

In research: Inferior longitudinal 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 Inferior longitudinal 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: Inferior longitudinal 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 Inferior longitudinal 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.
