motorium|məʊˈtɔərɪəm|
[mod.L., f. mōtōrius moving, f. L. mōt-, stem of movēre to move: cf. -ory1.]
1. Psychol. Collectively, the centres in the brain concerned in the function of voluntary muscle; that system of the body capable of initiating and putting into effect muscular movement.
1885J. Ross Handbk. Dis. Nervous Syst. 73 The central ends of the individual sensory mechanisms are unified by a collective centre—the sensorium commune—which is the general centre of nervous connections on the afferent side. It may also be supposed that the individual motor centres are unified by a general centre of nervous connections which may be regarded as a motorium commune. 1900Dorland Med. Dict. 398/1 Motorium, (1) a motor center; especially the common center of motor influences; (2) the motor apparatus of the body. 1924R. M. Ogden tr. Koffka's Growth of Mind 80 The optical sensorium and motorium can not be regarded as two independent pieces of apparatus, since for many types of performance they constitute a unitary organ. 1959S. Koch Psychology II. 76 For certain purposes, in dealing with transactions with the physical world (walking, performing a motor task, driving a car, etc.), the motorium may be considered to be the muscular apparatus of the organism. Even in such cases, however, it may prove to be useful to consider tools as a part of the motorium.
2. Zool. A cytoplasmic structure in some ciliate protozoa forming the centre of the neuromotor apparatus.
1914R. G. Sharp in Univ. Calif. Publ. Zool. XIII. 83 We now come to the description of what is believed to be the most interesting structure in the anatomy of this organism [sc. the protozoan Diplodinium ecaudatum]... The possibility of this structure functioning..as a neuromotor apparatus is suggested and..the designation neuromotor apparatus will be used, and its constituent parts will be described as a motorium or motor mass. 1926G. N. Calkins Biol. Protozoa ii. 104 Certain special types of cytoplasmic kinetic elements such as myonemes, motorium, and conductile fibers, are characteristic of the ciliates. 1940L. H. Hyman Invertebrates I. iii. 65 All these fibrils may center in a small body, the motorium. 1966New Scientist 3 Nov. 242/1 Another interesting feature of Euplotes is that, as Taylor first noticed in 1920, some of the cirri are connected by a system of minute fibrils to a structure near the front of the animal. This he called the motorium. |
