Post-legged

Post-legged 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 Post-legged rather than just read about it. In short: Post-legged describes a condition in which the joints in an animal are not set correctly. When an animal is post-legged, the leg joints are far too straight, with almost no bend in the legs.

Key takeaways

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

Reference excerpt

Post-legged describes a condition in which the joints in an animal are not set correctly. When an animal is post-legged, the leg joints are far too straight, with almost no bend in the legs. Four-legged animals must have some bend in the hocks, otherwise the hooves would wear unevenly, and this may result in lameness, or at least a rougher gait. The animal will not stand squarely on the ground, and this also increases the possibility of injury to the animal. When an animal is post-legged, the animal will have a much higher risk of lameness, perhaps even permanent. This means the animal can hardly move at all, and results in an extremely stressed animal. This may also result in the animal not being able to move to food, and could be life-threatening. Also, since the animal is in such pain, it may be so stressed that it won't calve well, and it will not produce good quality milk, -or any milk at all- in a cow. Animals with a problem in their leg joints are recommended to be removed from the breeding line, as this condition will only pass on, and cause much pain and suffering to the young of this species. Also, animals with an incorrect joint placement such as this will not do well in the ring at agricultural shows. This condition may affect cattle, horses, sheep, and many other livestock animals.

Worked examples

Example 1 — a first encounter with Post-legged

Start with the simplest possible case. Write down what Post-legged 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 Post-legged 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 Post-legged 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 Post-legged

In research: Post-legged 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 Post-legged 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: Post-legged is common in secondary-school and first-year university syllabi. It links to neighbouring topics Livestock, so understanding it makes those chapters shorter.
In everyday life: Look for Post-legged 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.

Frequently asked questions

What is Post-legged in simple terms?

Post-legged describes a condition in which the joints in an animal are not set correctly. When an animal is post-legged, the leg joints are far too straight, with almost no bend in the legs.

Why does Post-legged matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Post-legged?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
