Homologous
(gcide) | Homologous \Ho*mol"o*gous\, a. [Gr. ? assenting, agreeing; ? the
same + ? speech, discourse, proportion, ? to say, speak.]
Having the same relative position, proportion, value, or
structure. Especially:
(a) (Geom.) Corresponding in relative position and
proportion.
[1913 Webster]
In similar polygons, the corresponding sides,
angles, diagonals, etc., are homologous. --Davies &
Peck (Math.
Dict.).
(b) (Alg.) Having the same relative proportion or value, as
the two antecedents or the two consequents of a
proportion.
(c) (Chem.) Characterized by homology; belonging to the same
type or series; corresponding in composition and
properties. See Homology, 3.
(d) (Biol.) Being of the same typical structure; having like
relations to a fundamental type to structure; as, those
bones in the hand of man and the fore foot of a horse are
homologous that correspond in their structural relations,
that is, in their relations to the type structure of the
fore limb in vertebrates.
[1913 Webster]
Homologous stimulus. (Physiol.) See under Stimulus.

homologous
(wn) | homologous
adj 1: having the same evolutionary origin but not necessarily
the same function; "the wing of a bat and the arm of a
man are homologous" [ant: analogous, heterologic,
heterological, heterologous]
2: corresponding or similar in position or structure or function
or characteristics; especially derived from an organism of
the same species; "a homologous tissue graft" [ant:
autologous, heterologous] |

Homologous stimuli
(gcide) | Stimulus \Stim"u*lus\, n.; pl. Stimuli. [L., for stigmulus,
akin to L. instigare to stimulate. See Instigare, Stick,
v. t.]
1. A goad; hence, something that rouses the mind or spirits;
an incentive; as, the hope of gain is a powerful stimulus
to labor and action.
[1913 Webster]
2. That which excites or produces a temporary increase of
vital action, either in the whole organism or in any of
its parts; especially (Physiol.), any substance or agent
capable of evoking the activity of a nerve or irritable
muscle, or capable of producing an impression upon a
sensory organ or more particularly upon its specific end
organ.
[1913 Webster]
Note: Of the stimuli applied to the sensory apparatus,
physiologists distinguish two kinds: (a) {Homologous
stimuli}, which act only upon the end organ, and for
whose action the sense organs are especially adapted,
as the rods and cones of the retina for the vibrations
of the either. (b) Heterologous stimuli, which are
mechanical, chemical, electrical, etc., and act upon
the nervous elements of the sensory apparatus along
their entire course, producing, for example, the flash
of light beheld when the eye is struck. --Landois &
Stirling.
