What are the Facial Bones? Did you know that the face is made up of multiple bones and not just one large bone? Matter of fact, the face consists of 14 facial bones (6 paired and 2 unpaired). The 14 bones are: two zygoma/zygomatic bones, two lacrimal bones, two inferior nasal conchae bones, two palatine bones, two maxilla bones, two nasal bones, one vomer bone, and one mandible bone ( Kelley & Petersen, 2013, p. 49 ). The irregular sizes and shapes of these facial bones are fused together and articulates with joints that form different cavities, sinuses, and structures of the face. The facial bones serve as structural framework for the face, protect and provide support for vital organs and vessels of the face and skull, and aid in the movements and motion of the face and mouth ( Facial Bones – List of Names, Anatomy, & Labeled Diagram , 2022) .  Now let's learn more about these facial bones: Maxilla (or maxillary) (2/paired) : the largest, immovable facial bones that forms...

The adrenal glands are retroperitoneal structures and are located superior to the kidneys. They are part of the endocrine system, and its main purpose is to produce hormones that aid in metabolism, regulating stress, and other functions of the body (Pulse Radiology Institute, n.d., slide 14).  The adrenal glands also consist of the adrenal cortex (outer layer that produces dozens of adrenocortical steroids/corticosteroids) and the adrenal medulla (the inner layer that is responsible for the hormones epinephrine and norepinephrine, or flight-or-fight response) (Kelley & Petersen, 2013, pgs. 444-445).  Diagram of the adrenal glands (G, 2023) How to Identify the Adrenal Glands in an Image Unlike the easy recognizable structure of ...
