A
Human Design centers

Ajna center →

Also: Ajna

Human Design’s symbolic center for conceptualization and mental processing, not a neurological assessment.

Word origin, evidence & sources
Word origin · etymology
Sanskrit loanword in a modern compound.

Ājñā means command, order, or instruction. The name is borrowed from chakra terminology into the system's chart vocabulary.

How we know · epistemology
Symbolic center correspondence

This center is associated with concepts and mental processing in the teaching. Its definition is calculated from channels; it cannot establish intelligence, cognitive rigidity or the validity of a person's beliefs.

E
Human Design centers

Ego center →

Also: Heart center · Will center

Human Design’s symbolic will and material-resources center, counted among its four motors.

Word origin, evidence & sources
Word origin · etymology
Latin word adopted through psychology.

Ego is Latin for I. Human Design borrows the psychological self-word for its will-related center.

How we know · epistemology
Symbolic motor category

The system associates this motor center with will and material resources. Its channel-derived status does not measure cardiac function, moral character, financial competence or the strength of a person's commitments.

G
Human Design centers

G center →

Human Design’s symbolic center of identity, love and direction, not a measured anatomical structure.

Word origin, evidence & sources
Word origin · etymology
Modern letter-name within Human Design.

G is the center's established label. The cited teaching associates it with identity and direction; no unsupported expansion of the letter is asserted.

How we know · epistemology
Symbolic center correspondence

Identity, love and direction are themes assigned to this graph location. Its calculated status offers a contemplation prompt, not evidence about whether someone has a stable identity, can love or has a predetermined life direction.

H
Human Design centers

Head center →

Also: Head

Human Design’s symbolic inspiration and questioning center; its chart status does not measure the brain.

Word origin, evidence & sources
Word origin · etymology
Descriptive anatomical metaphor.

Head is the inherited English name for the upper body part. The chart places its pressure-center symbol at the head position.

How we know · epistemology
Symbolic center correspondence

Human Design assigns inspiration and questioning to this part of its graph. Channel rules determine its status, but that status does not measure brain activity or establish how often a person experiences ideas or uncertainty.

R
Human Design centers

Root center →

Also: Root

Human Design’s symbolic pressure and drive center, classified as a motor; chart labels do not diagnose stress.

Word origin, evidence & sources
Word origin · etymology
Ordinary English spatial metaphor.

Root names a plant's anchoring part, extended to a source or base. The chart applies the grounding metaphor at its lower end.

How we know · epistemology
Symbolic pressure and motor category

Pressure and drive are assigned themes, while channels determine the center's status. A defined or undefined Root does not establish a person's stress level, hormonal activity or ability to work under pressure.

S
Human Design centers

Sacral center →

Also: Sacral

Human Design’s symbolic response and sustaining-energy center; its definition is central to Generator classification.

Word origin, evidence & sources
Word origin · etymology
Anatomical adjective from sacrum.

Sacral refers to the sacrum, a name inherited from Latin os sacrum, sacred bone. The chart repurposes the anatomical location.

How we know · epistemology
Symbolic center and classification rule

Sacral definition has a decisive role in Generator classification. The structural result is checkable, while claims about sustainable energy or bodily responses are interpretive and cannot be read as measurements of physical capacity.

Human Design centers

Solar Plexus center →

Also: Solar Plexus

Human Design’s symbolic emotional center, treated as both a motor and an awareness center.

Word origin, evidence & sources
Word origin · etymology
Borrowed anatomical name.

Plexus is Latin for a braid or network; solar refers to the radiating, sun-like arrangement of the nerve network whose name is borrowed.

How we know · epistemology
Symbolic motor and awareness category

Human Design assigns emotional themes and priority in its authority hierarchy to this center. That chart rule does not assess emotional health or demonstrate a particular emotional rhythm in the person being described.

Human Design centers

Splenic center →

Also: Spleen center

Human Design’s symbolic instinct and present-moment awareness center; it is not a test of immune function.

Word origin, evidence & sources
Word origin · etymology
Anatomical adjective.

Splenic means relating to the spleen, from Greek splen through Latin. The diagram borrows the organ's name for a center.

How we know · epistemology
Symbolic awareness correspondence

The center's themes involve instinct and immediate awareness within Human Design. Its channel pattern does not test the spleen, immunity or the accuracy of an intuition; those are different kinds of claims from graph classification.

T
Human Design centers

Throat center →

Also: Throat

Human Design’s symbolic expression and manifestation center; connections to motors help determine type.

Word origin, evidence & sources
Word origin · etymology
Descriptive anatomical metaphor.

Throat is an inherited English body-part word. It names the diagram's expression center by its bodily location.

How we know · epistemology
Symbolic center and graph role

The teaching associates this center with expression, and its connections help classify type. A motor path is a property of the diagram; it does not directly measure communication skill or a person's capacity to make things happen.
