The same substances diffusing from the ovum during its development in the uterus would continue to stimulate the follicle cells, and thus explain not merely their persistence, but their secretory activity. The ovum being no longer present in the ovary, the secretions would remain in the follicular cells, and the corpus luteum would be explained.
My explanation of this case is simply one of reflex action; that is, by a singular complication this follicle fell in the track of the glosso-pharyngeal, the pharyngeal-plexus, the external-laryngeal and the recurrent laryngeal nerves, which, as it were, sounded the alarm for retreat of the phonating muscles whose harmonious action was necessary to produce the medium G sharp.
In the wall of the follicle two layers are distinguished, the theca externa, which is more fibrous, and the theca interna, which is more cellular.
As these are pushed upwards by new ones formed beneath, they are compressed, and the shape of the follicle determines their cylindrical growth, the shaft of the hair. The medulla of the hair contains the pigment granules or coloring matter, which may be of any shade between a light yellow and an intense black. It is this that gives the great variety in color.
We have the odoriferous glands of sebaceous origin, and with them the prepuce of the clitoris which has been described as a kind of gigantic sebaceous follicle with the clitoris occupying its interior.
Upon the whole history of the evolution of each tooth, in the growth of the dental follicle and its walls, the fruition of the dentinal germ, the making of the enamel organ, the dental pulp, the cementum and the peridental membrane, the endocrines leave their mark. There are certain general statements about the teeth and the internal secretions that can be made.
A #boil# results when the infection is located in a hair follicle or sebaceous gland. A hard, painful, conical swelling develops, to which, so long as the skin retains its normal appearance, the term "blind boil" is applied. Usually, however, the skin becomes red, and after a time breaks, giving exit to a drop or two of thick pus.
Of the original feathers, one, the left central posterior covert, continued to grow till 13th July 1902, when it was 2 feet 9-1/2 inches long without the part contained in the follicle. All the feathers pulled out immediately commenced to grow again, except the last two pulled out 27th May and 13th July, which did not grow again till the following moulting season, in September.
After an interval of from six to ten days a soft white slough is discharged; this is known as the "core," and consists of the necrosed hair follicle or sebaceous gland. After the separation of the core the boil heals rapidly, leaving a small depressed scar.
The developing ovum within the uterus may, however, reasonably be supposed to give off something which is absorbed into the maternal blood, and this something would be of the same nature as that which was given off by the ovum while still within the ovarian follicle.
