neurohypophysis
Very Low FrequencyTechnical (Medical, Biological)
Definition
Meaning
The posterior lobe of the pituitary gland that stores and releases hormones produced by the hypothalamus.
The neurohypophysis is a neuroendocrine structure composed of neural tissue that acts as a storage and release site for vasopressin (antidiuretic hormone) and oxytocin, hormones crucial for water balance, blood pressure regulation, and reproductive functions like childbirth and lactation.
Linguistics
Semantic Notes
The term is almost exclusively used in technical medical and biological contexts. It is a compound of 'neuro-' (relating to nerves or the nervous system) and 'hypophysis' (the scientific term for the pituitary gland). Its meaning is highly specific and not used metaphorically.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. Both varieties use the same term in technical contexts.
Connotations
Identical in both dialects. It is a precise anatomical term.
Frequency
Extremely rare in non-specialist language in both regions. Its frequency is identical and confined to specialist literature.

Never used.
Academic
Exclusively used in advanced medical, neuroscience, and endocrinology texts and research papers.
Everyday
Virtually never used. A general speaker would say 'pituitary gland' or 'back part of the pituitary'.
Technical

Examples
By Part of Speech
adjective
British English
- neurohypophyseal dysfunction
- neurohypophyseal hormone secretion
American English
- neurohypophyseal disorder
- neurohypophyseal axis
Examples
By CEFR Level
- The doctor explained that the problem might be in the part of the brain called the pituitary gland, specifically its posterior lobe.
- Oxytocin and vasopressin are synthesized in the hypothalamus but are stored and secreted by the neurohypophysis.
Learning
Memory Aids
Mnemonic
Link the 'neuro' part to 'neuron' (nerve cell) and 'hypophysis' to 'under-growth' (pituitary gland). Think: the 'nerve-related under-growth' at the base of the brain.
Conceptual Metaphor
A STORAGE AND DISTRIBUTION CENTRE for brain-made hormones. It is a 'warehouse' for the hypothalamus.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calques. The correct Russian equivalent is 'нейрогипофиз' or 'задняя доля гипофиза'.
Common Mistakes
- Confusing it with the entire pituitary gland (hypophysis).
- Using it in non-scientific contexts.
- Mispronouncing it, e.g., stressing the wrong syllable.

FAQ
Frequently Asked Questions
No. The neurohypophysis is specifically the posterior lobe of the pituitary gland. The pituitary gland (hypophysis) consists of two main parts: the adenohypophysis (anterior lobe) and the neurohypophysis (posterior lobe).
The two primary hormones are oxytocin, which is involved in childbirth and social bonding, and vasopressin (also called antidiuretic hormone or ADH), which regulates water balance and blood pressure.
It is a standard term in endocrinology, human anatomy, physiology, neuroscience, veterinary medicine, and related biological sciences.
In most technical contexts, yes, 'posterior pituitary' is the most common and functionally equivalent synonym. 'Neurohypophysis' is the more precise anatomical/embryological term.
