ANATOMY IN A NUTSHELL. 431 



somatic, vasomotor, pilo motor, and secretory. K originates in the sympa- 

 thetic ganglion and passes along the recurrent branch to the vertebrae, ligaments, 

 spinal vessels, and dura mater of the cord. L originates in the sympathetic 

 ganglion and passes along the gray rami for a short distance then it leaves it to 

 pass to the vertebra?, intercostal and lumbar vessels. M originates in the sym- 

 pathetic ganglion and like all others that originate in this ganglion are called 

 rami efferentes. X originates in the sympathetic ganglion and pass to the gang- 

 lion above it or the ganglion below it. 



LESSON ( XXV II. 



"The gross anatomy of the cervical sympathetic gives no idea of its true 

 anatomical relations as revealed by physiological experiments and pathological 

 phenomena. The physiological connections as at present understood mar be 

 summed up as follows: 



1. Pupillo-dilator fibers pass by white rami communicantes from the 

 first, second and third thoracic nerves and ascend in the sympathetic cord to 

 the superior cervical ganglion to form arborizations round its cells. Thence 

 gray fibers pass to the Gasserian ganglion and reach the eye-ball by the ophthal- 

 mic division of the fifth and long ciliary nerves. 



2. Motor fibers to the involuntary muscles of the orbit and eyelids from 

 the fourth and fifth thoracic nerves follow a similar course. 



3. Yaso-motor-fibers to the head, secretory fibers to the submaxillary 

 gland, pilomotor fibres to the head and neck are derived from the upper thor- 

 acic nerves and reach their areas of distribution after a similar interruption in 

 the superior cervical ganglion. 



4. The accelerator fibers of the heart are derived from the upper tho- 

 racic spinal nerves, and end similarly in the middle and lower cervical ganglion 

 gray fibers in the cervical cardiac nerv< s completing the connection." — (Gerrish). 



" A patient with laceration of the cervix goes through five stages: (1) irri- 

 tation; (2) INDKiESTION; (3) .MALNUTRITION! (4) ANEMIA; (5) NEUROSIS. 



These stages will appear if the patient has a neuropathic constitution or 

 diathesis. 



"A general summary of the abdominal brain is: that (a) it presides over 

 nutrition; (b) it controls circulation: (c) i1 controls gland secretion; (d) it pre- 

 sides over the organs of g< n< ration; (e) it influences in a dominant, though not 

 an absolute control its peripheral visceral automatic ganglia." — (Byron Rob- 

 inson).

 The cortex of each hemisphere of tin brain is in communication with the 

 opposite half of the body by means of fibers conducting impulses to and from 

 it. These fibers maybe divided into two sets, according to the dir< ction of con- 

 duction : centrifugal, or motor, which conduct < xcitations from the cortex to the 

 various muscles of the body: and centripetal, or sensory, which convey excita-
