The retinohypothalamic tract (RHT) is a photic neural input pathway involved in the circadian rhythms of mammals.
 The origin of the retinohypothalamic tract is the intrinsically photosensitive retinal ganglion cells (ipRGC), which contain the photopigment melanopsin.
 The axons of the ipRGCs belonging to the retinohypothalamic tract project directly, monosynaptically, to the suprachiasmatic nuclei (SCN) via the optic nerve and the optic chiasm.
 The suprachiasmatic nuclei receive and interpret information on environmental light, dark and day length, important in the entrainment of the "body clock".
 They can coordinate peripheral "clocks" and direct the pineal gland to secrete the hormone melatonin.
Donkey Punch is a punch or cocktail made of 1 part rum, 3 parts orange juice, 2 parts ginger ale, 1 part pineapple juice and Grenadine syrup.
 The ingredients are poured into shaker filled with ice and shaken well befoure pouring it into a large glass filled with ice cubes.
 The ingredients can also be mixed together in a punch bowl and served with ice and orange slices floating on top.
Picon Punch, or simply Picon, is a highball cocktail made with an Amaro liqueur, soda water, grenadine, a splash of lemon, and a bit of brandy floating on top.
 The drink is identified as Basque, but was created by Basque immigrants in the U.S. and taken back to the Basque region in the Pyrenees.
 It is popular in Basque Restaurants and Bars in Boise and southern Idaho, in Bakersfield, California, and Northern Nevada.
The outer and inner segments of vertebrate retina rod photoreceptor cells contain phosducin, a soluble phosphoprotein that complexes with the beta/gamma-subunits of the guanosine triphosphate-binding protein, transducin.
 Light-induced changes in cyclic nucleotide levels modulate the phosphorylation of phosducin by protein kinase A.
 The protein is thought to participate in the regulation of visual phototransduction or in the integration of photoreceptor metabolism.
 Similar proteins have been isolated from the pineal gland and it is believed that the function of the protein is the same in both retina and pineal gland.
The Monkey Gland is a cocktail of gin, orange juice, grenadine and absinthe created in the 1920s by Harry MacElhone, owner of Harry's New York Bar in Paris, France.
The preorbital gland is a paired exocrine gland found in many species of hoofed animals, which is homologous to the lacrimal gland found in humans.
 These glands are trenchlike slits of dark blue to black, nearly bare skin extending from the medial canthus of each eye.
 They are lined by a combination of sebaceous and sudoriferous glands, and they produce secretions which contain pheromones and other semiochemical compounds.
 Ungulates frequently deposit these secretions on twigs and grass as a means of communication with other animals.
Monkey gland may refer to surgeon Serge Voronoff's technique of grafting monkey testicle tissue on to the testicles of men for purportedly therapeutic purposes.
 It may also refer to:
Monkey gland sauce is a restaurant item in South Africa.
 The tangy sauce is prepared in several manners, and may include a blend of fruit and spices.
 It is typically served with meats, such as steak, hamburgers, pork ribs or chicken.
 Several popular South African fast food chains serve a Monkey gland Burger.
Planter's Punch is an IBA Official Cocktail made of dark rum, several juices, grenadine syrup, sugar syrup, and Angostura bitters.
A mammary alveolus (plural: alveoli, from Latin "alveolus", "little cavity") is a small cavity or sac found in the mammary gland.
 Mammary alveoli are the site of milk production and storage in the mammary gland.
 Mammary alveoli cluster into groups called lobules, and each breast may contain 15–20 of these lobules.
 The lobules drain milk through the lactiferous ducts out of the nipples.

Question: Do both Planter's Punch and Monkey Gland contain grenadine?
Answer: yes
