Purpose and description
Enable an AI agent to recognise the nape as the posterior neck region, record its boundaries and observable state, and assess whether a proposed observation or contact concerns that region.
The nape is the posterior region of the neck, between the back of the head and the upper back.
It can be Locate and annotate the nape on a body representation using a stated boundary convention.; Record visible features while distinguishing obscured areas from observed absence.; Compare observations across time with head position, lighting and hair coverage documented.; Associate collars, straps or other items with their contact locations on the nape.; Route observations extending into the scalp, lateral neck or upper back to the corresponding regional models.; Determine the location, access and consent requirements for a proposed non-invasive observation or personal-care action..
Distinguishing features
The candidate region is on the posterior aspect of the neck, rather than the throat or side of the neck.
The candidate is a region of a body, rather than a detachable object or a single anatomical structure.
Its stated extent lies between the back of the head and the transition toward the upper back, with the boundary convention recorded.
A hairline may help describe its appearance, but hair coverage alone does not determine whether a location belongs to the nape.
References to underlying cervical structures count as relationships to the region, rather than making those structures synonymous with the nape.
Scope
+ Location at the back of the neck and relationships to the head, shoulders and remaining neck
+ Explicit conventions for upper, lower and lateral regional boundaries
+ Surface features such as skin, hairline, folds and visible markings
+ Changes in appearance and accessibility with head position
+ Reported local sensations and observed surface changes without diagnostic interpretation
+ Contact with clothing, equipment and permitted personal-care activities
- The neck as a whole, including its anterior and lateral regions
- The scalp and back of the head beyond the selected nape boundary
- The upper back and shoulders beyond the selected nape boundary
- Independent models of cervical vertebrae, muscles, nerves and other underlying structures
- Diagnosis and treatment of neck disorders or injuries
- Figurative meanings or unrelated uses of the word nape
Characteristics
- Bearing organism
- Reference to the individual organism and its species Anchors the region to a body and makes any extension beyond human usage explicit.
- Regional boundary convention
- Named anatomical convention or explicitly described upper, lower and lateral limits; unspecified Prevents observations made with different regional extents from being treated as directly comparable.
- Relationship to adjacent regions
- Connections to posterior head, lateral neck, shoulders and upper back Supports localisation and detects observations that cross into neighbouring regions.
- Head and neck position
- Neutral, flexed, extended, rotated, combined or unrecorded Provides context for the visibility of folds, landmarks and the exposed surface.
- Hair coverage
- Uncovered, partly covered, fully obscured or indeterminate; hairline description Distinguishes the anatomical region from the portion visible below or through hair.
- Observable surface state
- Localised descriptions of colour, texture, folds, markings and visible surface changes; not observed Allows changes to be recorded without assigning a cause or diagnosis.
- Reported local sensation
- Person's description, location and time, including explicit absence or unknown Keeps subjective reports distinct from externally observed features.
- Contact or coverage
- Contact with collar, strap, headwear, hair, hand or other identified item; duration if known Connects local observations and accessibility to specific contact conditions.

Regional identity and boundaries Establishes what the word nape identifies and how its extent is represented.
The nape is a named body region whose practical boundaries must be stated rather than inferred from an object outline.
Anatomical sense
Anchors the entry to the posterior neck sense and its bearing organism.
Posterior neck region
Treat the nape as a region at the back of the neck; retain the species and terminology context with each application.
- Does this use of nape identify the back of the neck, and which organism bears the region? definition
- Which anatomical or terminology source supports applying this name to the recorded species? provenance
Regional limits
Separates the nape from neighbouring head, neck and back regions.
Explicit boundary landmarks
Record the landmarks or descriptive limits used for the region, including uncertainty where adjacent regions merge.
- What landmarks define the upper, lower and lateral limits in this application? boundary
- Does the observation remain within those limits or extend onto the scalp, lateral neck, shoulders or upper back? boundary
Surface and hairline Describes the nape's visible surface and the hair coverage that affects its interpretation.
The visible area below the hairline can differ from the anatomical region, making coverage and surface localisation essential.
Hairline and visibility
Records how hair exposes or obscures the posterior neck.
Coverage independent of boundary
Represent hairline position and hair coverage as surface descriptors, rather than substituting them for regional limits.
- Where is the visible hairline relative to the selected nape landmarks? measurement
- Which parts of the nape are obscured by hair or hairstyle rather than absent from the region? boundary
Local surface description
Localises visible features within the posterior neck region.
Mapped surface features
Describe folds, markings and surface changes by location, extent and observation conditions without inferring their cause.
- Where is each feature relative to the posterior midline, hairline and selected lower boundary? measurement
- What feature extent is observable, in millimetres when a valid scale is available? measurement
Posture and local observation Places observations of the nape in their positional and temporal context.
Head position affects the presentation of the posterior neck, while local sensations require attribution to the person reporting them.
Position-dependent appearance
Records posture when interpreting visible contours and access to the nape.
Comparable observation position
Attach head position and viewing direction to observations so apparent differences can be assessed in context.
- Was the head neutral, flexed, extended or rotated when the nape was observed? measurement
- Were viewing direction and head position sufficiently consistent to compare the recorded folds or contours? measurement
Local reports and changes
Distinguishes reported sensations from observed changes at the nape.
Attributed regional observations
Record what was seen or reported, by whom and when, without treating regional localisation as evidence of an underlying cause.
- Is the recorded feature directly observed, reported by the person or copied from another account? provenance
- Is the reported sensation confined to the nape or described as extending into adjacent regions? boundary
Contact and care context Represents items and permitted activities that touch, cover or expose the nape.
Collars, rear straps, hair and personal-care activities interact with this specific region and affect its accessibility.
Wearable contact
Maps clothing and equipment contact onto the posterior neck.
Nape contact footprint
Identify where an item touches or covers the nape and whether that relationship changes with position.
- Which part of the collar, strap or other item contacts the nape, and where is that contact located? boundary
- Does the contact location or coverage change during the person's observed head movement? measurement
Observation and personal care
Defines the regional access and permission context for non-invasive activities.
Permitted nape access
Represent the intended observation or care activity, its target area and the person's permission before exposing or touching the region.
- What observation, washing, grooming or other non-invasive activity is intended at the nape? action
- What consent and movement of hair, clothing or equipment are needed to access the intended area? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.
Check these first
Recalled without web access and unsourced; every item is a lead to verify.
- The anatomical sense is assumed because no sense was recorded; nape is a body region, not a device or tool.
- The term is also used in animal anatomy, particularly bird plumage descriptions.
- Precise boundaries and measurement landmarks depend on the anatomical or practical convention being used.
- Which of these check these first hold for the sense of nape this model covers, and on what evidence? provenance
Real-world use
Recalled without web access and unsourced; every item is a lead to verify.
- Anatomical descriptions use the nape to locate features on the back of the neck.
- Hairdressing uses the nape as a reference area for hairlines and haircut shaping.
- Garment fitting uses the nape as a reference point for some back-length measurements.
- Bird identification uses nape plumage colour and markings as distinguishing features.
- Which of these real-world use hold for the sense of nape this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- neck - The neck includes the entire region connecting the head to the trunk; the nape is its posterior part.
- occiput - The occiput is the back of the head, above the nape.
- cervical spine - The cervical spine is the vertebral column within the neck; the nape is a body region rather than a skeletal structure.
- upper back - The upper back belongs to the trunk below the neck; the nape belongs to the posterior neck.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of nape this model covers, and on what evidence? provenance
What the second pass must settle
- Which authoritative anatomical convention should define the nape's upper, lower and lateral boundaries for this registry?
- Does vr.tr.nape intend human anatomy only, or should it include species-specific uses of nape in other animals?
- Does an existing Vercy neck or anatomical-region model already own this concept, requiring a link instead of a separate publication?
- What depth, if any, should the regional model own beyond the surface, and how should underlying structures be related without duplicating their models?
- Which landmark and posture conventions provide sufficiently repeatable nape observations across individuals and recording sessions?
