An attempt is made to name most of the acupuncture points in the face and forehead region using anatomic nomenclature known to western medicine. All acupuncture points in the face and forehead region are located along terminal or cutaneous branches of the trigeminal nerve and the motor points formed between muscular branches of the facial nerve to the muscles of facial expression. It is believed such nomenclatures will be comprehensible to basic medical scientists and clinical practitioners who have knowledge of anatomical sciences.

To determine if the adrenal gland plays a role in the thymic involution which occurs spontaneously in "lethargic" mutant mice, three different studies were made. Morphological studies were made first to determine if there was an indication of histological changes in the adrenal glands. Next, serum levels of corticosterone were measured by radioimmunoassay. Finally, mice were unilaterally adrenalectomized to see if such treatment would improve various symptoms of "lethargic" mutants. Results of the studies showed that lipid granules in the cortical cells of "lethargic"mutants were greatly reduced in number during the time of spontaneous thymic involution, and the mutant mice had a significantly higher level of serum corticosterone than the normal controls. Mutant mice unilaterally adrenalectomized at 15 days of age showed a marked improvement in their condition and their mortality rate decreased. It is concluded that spontaneous thymic involution of "lethargic" mutants is probably associated with adrenocortical hypersecretion.

This is the sixth and final communication in a series describing acupuncture points by anatomic nomenclature. Most acupuncture points on the lateral and posterior surfaces of the lower limb are located along routes of the sacral plexus. These points belong to acupuncture meridians carrying "Yang energy" in the lower limbs. The meridians are traditionally known as the Urinary Bladder on the posterior surface of the lower limb, Gall Bladder on the lateral surface of the lower limb, and Stomach on the anterior surface of the leg and dorsum of the foot.

This communication is the fifth in a series of six publications describing acupuncture points by anatomic nomenclature. This article describes acupuncture points in the lumbar region of the posterior body wall, the inguinal and pelvic regions of the lower abdomen, and the medial surface of the thigh and leg. Acupuncture points in these regions are generally established by anatomic features of the lumbar spinal nerves. Nerve branches of the posterior primary rami of the lumbar spinal nerves and the lumbar plexus provide the anatomic basis for acupuncture points in these regions and are used to name the points accordingly.
