hand
Let an agent handle the hand by anatomy, function, laterality, hygiene and injury, routing medical questions to professionals.
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 handle the hand by anatomy, function, laterality, hygiene and injury, routing medical questions to professionals.
The prehensile end part of the human arm (and of some other primates), consisting of the wrist, palm, fingers and thumb, used for grasping, manipulation, touch and communication.
What it is for: Grasping, manipulating, sensing, gesturing and signing.
It can be wash hands to prevent infection; protect hands at work; rehabilitate after injury; use in sign language and gesture.
Distinguishing features
Opposable thumb
Fine motor control
Dense touch receptors
Handedness varies
What it looks like
Palm, four fingers and an opposable thumb joined at the wrist.
Physical character
bones: 27 bones - including wrist
grip strength (adult): about 20-60 kg - varies by sex, age and hand
How it is recognised
27 bones in the human hand
Left or right hand
Robotic hands are manipulators
