what means in front of when using anatomical directional terms
Anatomical terms of location Anterior refers to what is in front (from Latin ante, meaning "before") and posterior, what is to the back of the subject (from Latin post, meaning "after").[10] For example, in a dog the nose is anterior to the eyes and the tail is considered the most posterior part; in many fish the gill openings are posterior to the eyes, but anterior to the tail.
Sleeping positions The Indian Vastu Shastra and Chinese Feng shui systems describe favorable and unfavorable geographical directions (north, south, east, west) for sleeping. Vastu Shastra suggests not to sleep towards North for people living in Northern hemisphere and not towards South in case of Southern Hemisphere. Blog by Sadhguru (Isha Foundation) quotes, "East is the best direction. North-east is okay. West is alright. South, if you must. North, no. This is true as long as you are in the northern hemisphere – sleeping with your head towards any side except north is okay. In the southern hemisphere, don’t put your head to the south."[11]
