Purpose and description
Enable an AI agent to recognise an adrenal gland, record its anatomical and endocrine state, and identify what evidence and professional authority are needed before acting on it.
An adrenal gland is a paired endocrine organ in mammals, located near the upper pole of a kidney in humans, whose cortex produces steroid hormones and whose medulla produces catecholamines.
It can be Associate imaging, laboratory and pathology observations with the correct gland, compartment and time.; Compare gland and lesion measurements longitudinally with their acquisition methods preserved.; Organise evidence of cortical and medullary function while retaining uncertainty about laterality.; Identify missing context that prevents interpretation of a hormone measurement or structural finding.; Record clinician-authorised surveillance, sampling or intervention and track subsequent anatomical and endocrine changes..
Distinguishing features
Identification requires adrenal anatomy or tissue evidence; proximity to a kidney alone does not establish adrenal identity.
In the mammalian scope, the organ combines a steroid-producing cortex and a catecholamine-producing medulla, unlike the kidney or a typical lymph node.
A cortical zone, medullary lesion or adrenal-derived tumour is a component or pathological entity, not automatically a complete adrenal gland.
An individual gland has a side and organ-level continuity; a bilateral hormone measurement usually cannot identify which gland produced the measured output.
Adrenal tissue outside the usual location requires an explicit distinction between an ectopic gland, accessory tissue and a lesion.
Scope
+ Organ identity, laterality, location and relationship to the contralateral gland
+ Cortical zones, medulla, vascular supply and tissue integrity
+ Adrenal hormone production and its regulation
+ Structural abnormalities and evidence of altered endocrine function
+ Effects of observation, sampling, medication and procedures on the gland
- Kidney anatomy and urinary function beyond relationships needed to locate the gland
- Complete hypothalamic, pituitary and systemic endocrine models
- Standalone models of adrenal hormones as chemical substances
- Full disease models for adrenal insufficiency, hormone excess and adrenal tumours
- Whole-organism taxonomy, population ecology and conservation status
- Autonomous diagnosis, prescribing or procedural treatment decisions
Characteristics
- Species and developmental stage
- Species identifier; fetal, neonatal, juvenile or adult stage with age Anatomical organisation and interpretation of endocrine findings depend on species and development.
- Laterality and organ presence
- Left or right; present, absent, partially resected or uncertain Keeps observations attached to the correct gland and supports assessment of remaining adrenal tissue.
- Position and anatomical relationships
- Location relative to kidney, major vessels and surrounding structures; evidence modality Supports identification and procedure planning without equating location with tissue identity.
- Size and measurement basis
- Dimensions in mm; volume in mL when available; modality, method and date Allows defensible comparison over time while distinguishing whole-gland measurements from lesion measurements.
- Compartment and cortical zone
- Cortex, medulla, mixed or unresolved; cortical zone when supported Connects tissue observations to the appropriate secretory role and pathological possibilities.
- Hormone assessment
- Analyte-specific concentration or excretion units, specimen, assay, collection time and reference interval Prevents hormone values from being interpreted without their measurement conditions.
- Functional assessment
- Adequate, deficient, excessive, mixed or indeterminate; hormone axis and supporting evidence Separates endocrine performance from anatomical appearance.
- Regulatory and medication context
- Relevant regulatory measurements, physiological conditions and medication exposures Observed secretion can reflect external regulation or medication effects rather than intrinsic gland disease.
- Lesion characteristics
- Presence, compartment, focality, dimensions, imaging or pathology descriptors and diagnostic certainty Supports lesion tracking without assuming that a mass is malignant or hormonally active.
- Contralateral gland and intervention history
- Linked opposite gland; dated surgery, irradiation, injury or relevant treatment An individual gland's significance depends partly on the condition of the other gland and previous interventions.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
Adrenal identity and anatomy Establishes which organ is represented and how its parts are situated.
Adrenal identity cannot be reduced to a structure above a kidney or a hormone result.
Organ identification
Anchors the gland to a subject, species, side and anatomical location.
Individual gland boundary
Distinguishes a complete gland from paired adrenal function, accessory tissue and adjacent structures.
- Which subject, species and side does this gland belong to, and what evidence establishes its identity? provenance
- Does the record represent a whole gland, a remnant, accessory adrenal tissue or only a suspected adrenal-region structure? boundary
Compartments and vascular relations
Represents internal organisation and connections relevant to viability and access.
Cortex, medulla and vessels
Records demonstrated compartments, cortical zones and vascular relationships without inferring unseen anatomy.
- Which cortical zones and medullary structures are demonstrated, and by what imaging or tissue evidence? provenance
- What arterial, venous or neighbouring-organ relationships affect this gland's perfusion or procedural access? boundary
Adrenal secretory function Separates cortical steroid output from medullary catecholamine output.
The two compartments require different observations, interpretations and functional assessments.
Cortical steroid function
Organises evidence concerning glucocorticoids, mineralocorticoids and adrenal androgens.
Axis-specific cortical output
Treats each cortical hormone axis separately and distinguishes systemic results from gland-specific evidence.
- Which steroid analytes or metabolites were measured, with what specimen, assay, units and collection conditions? measurement
- Does the evidence describe combined adrenal output or support attribution to this individual gland? boundary
Medullary secretory function
Organises catecholamine and metabolite evidence associated with adrenal medullary activity.
Medullary output attribution
Keeps biochemical evidence separate from claims about its anatomical source.
- Which catecholamines or metabolites were measured, and what collection conditions and reference intervals accompany them? measurement
- What evidence attributes an abnormal result to this gland rather than another source or a measurement confounder? provenance
Regulation and functional reserve Places adrenal measurements within regulatory signals, physiological demand and test conditions.
A hormone concentration alone does not establish autonomous secretion or the capacity to meet demand.
Regulatory inputs
Connects cortical and medullary activity to their relevant regulatory pathways.
Axis-specific regulatory context
Separates ACTH-related regulation, renin-angiotensin and potassium context, and sympathetic influences.
- Which regulatory pathway is relevant to the hormone finding, and what concurrent measurements or observations describe it? definition
- What medication exposure, time of day, posture, acute stress or illness could alter the observed result? provenance
Dynamic response and reserve
Records responses to documented testing and changes in physiological demand.
Interpretable functional response
Preserves the protocol and interpretive basis of stimulation or suppression testing.
- If dynamic testing was performed, what protocol, sampling times, assay and interpretation criteria were used? measurement
- What can the result establish about combined adrenal capacity, and what remains unresolved about this gland alone? boundary
Structural and pathological state Tracks tissue integrity, lesions and the certainty of pathological interpretations.
Structural abnormalities and endocrine abnormalities may occur independently and must be evaluated separately.
Morphology and tissue integrity
Describes gland shape, size and evidence of focal or diffuse tissue change.
Documented adrenal change
Records observed enlargement, atrophy, haemorrhage or other tissue changes with their evidential limits.
- What whole-gland or tissue changes are observed, and which modality and date establish them? measurement
- Are serial observations sufficiently comparable to support a claim of growth, resolution or tissue loss? measurement
Lesion characterisation
Separates lesion location and behaviour from diagnostic labels.
Lesion origin and functional status
Tracks anatomical origin, secretory evidence and diagnostic confidence as distinct properties.
- What evidence supports cortical, medullary, metastatic, extra-adrenal or unresolved origin? provenance
- What independently supports the lesion's functional status and its benign, malignant or indeterminate classification? provenance
Adrenal observation and intervention Connects proposed actions and completed interventions to gland-specific evidence and remaining function.
Sampling or altering adrenal tissue can have endocrine consequences that depend on both glands.
Assessment and action readiness
Records the clinical question, decision authority and unresolved prerequisites for an action.
Justified adrenal action
Makes surveillance, additional testing and invasive procedures reviewable against their intended purpose.
- What unresolved question would the proposed imaging, biochemical test, sampling or procedure answer? action
- What endocrine evaluation, risk assessment and responsible clinician authorisation are documented before an invasive action? action
Post-intervention adrenal state
Tracks residual tissue and endocrine consequences after treatment or injury.
Remaining tissue and endocrine support
Links the treated gland, contralateral gland and documented follow-up requirements.
- What adrenal tissue remains on each side after the intervention, and what evidence describes its function? measurement
- What clinician-directed hormone support, monitoring and reassessment plan is recorded? action
