Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain digits as anatomical structures in humans and other animals, relay anatomical terminology and numbering, describe common injuries and conditions in general terms, and route personal medical questions to clinicians.

A finger or toe: one of the jointed extremities at the end of a hand or foot in humans and other tetrapods, with bones, joints, tendons, nails or claws and sensitive pads; digits are counted, named and numbered in anatomy, vary across species from five to fewer or fused forms, and are central to grasping, walking and touch.

What it is for: Grasping, manipulation, locomotion and touch.

It can be explain anatomy and numbering; compare digits across species; describe common injuries and conditions in general terms; route personal questions to clinicians.

Distinguishing features

Jointed extremity of the limb

Nails or claws and sensory pads

Numbered and named in anatomy

Species variation in number and form

What it looks like

A jointed projection at the end of a hand or foot, with a nail or claw and a sensitive pad.

Physical character

digits per hand or foot in humans: 5 digits - variation exists

phalanges per digit: 2 in the thumb and big toe, 3 in the others bones - humans

How it is recognised

Fingers and toes of humans; digits of other tetrapods

Numbered from the thumb or big toe

The term digit meaning a numeral is a different sense
