Head and neck anatomy through the circulatory system and by direct connection of neurons. Also, within the cranium, the pineal gland, which attaches to the thalamus, controls the body's 24-hour rhythms circadian rhythm through the release of melatonin. The pituitary gland secretes hormones that directly impact the body as well as hormones that indirectly control body functions because they activate other endocrine glands, such as the adrenal cortex (ACTH) and the thyroid gland (TSH).

Ciaccio's glands sometimes called "Wolfring's glands" after Polish ophthalmologist Emilj von Wolfring (1832-1906), who described them during the same time period as did Ciaccio. Another type of accessory lacrimal gland are "Krause's glands", which are smaller, more numerous than "Ciaccio's glands" and are found along the superior and inferior fornices of the conjunctival sac. Ciaccio's glands Ciaccio's glands or Wolfring's glands are small tubular accessory lacrimal glands ("glandulae lacrimales accessoriae") found in the lacrimal caruncle of the eyelid. They are located in the upper border of the tarsus, approximately in the middle between the extremities of the tarsal glands. Sometimes they are
