Herring bodies

Herring bodies 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 Herring bodies rather than just read about it. In short: Herring bodies or neurosecretory bodies are structures found in the posterior pituitary. They represent the terminal end of the axons from the hypothalamus, and hormones are temporarily stored in these locations.

Key takeaways

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

Reference excerpt

Herring bodies or neurosecretory bodies are structures found in the posterior pituitary. They represent the terminal end of the axons from the hypothalamus, and hormones are temporarily stored in these locations. They are neurosecretory terminals. Antidiuretic hormone (ADH) and oxytocin are both stored in Herring bodies, but are not stored simultaneously in the same Herring body. In addition, each Herring body also contains ATP and a type of neurophysin. Neurophysins are binding proteins, of which there are two types: neurophysin I and neurophysin II, which bind to oxytocin and ADH, respectively. Neurophysin and its hormone become a complex considered a single protein and stored in the neurohypophysis. Upon stimulation by the hypothalamus, secretory granules release stored hormones into the bloodstream. Fibers from supraoptic nuclei are concerned with ADH secretion; paraventricular nuclei with oxytocin. This anatomical structure was first described by Percy Theodore Herring in 1908.

Worked examples

Example 1 — a first encounter with Herring bodies

Start with the simplest possible case. Write down what Herring bodies 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 Herring bodies 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 Herring bodies 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 Herring bodies

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