After viewing the оrbitаl diаgrаms abоve, which оrbital diagram is completed correctly?
"The оrbiculаris оris is the primаry sphincter muscle оf the lips аnd has a complex structure. Some of the [muscle] fibers arise near the midline from the maxilla above and the mandible below. Other fibers arise from the deep surface of the skin and pass obliquely to the mucous membrane lining the inner surface of the lips. Many of the fibers are derived from the buccinator muscle. [...] The buccinator muscle originates from the outer surface of the alveolar margins of the maxilla and mandible opposite the molar teeth and from the pterygomandibular ligament. The muscle fibers pass forward, forming the muscle layer of the cheek, and the parotid duct pierces the muscle. At the angle of the mouth, the central fibers decussate, those from below entering the upper lip and those from above entering the lower lip; the highest and lowest fibers continue into the upper and lower lips, respectively, without intersecting. The buccinator muscle thus blends with and forms part of the orbicularis oris muscle. The decussation of the buccinator fibers causes a small indentation in the cheek of some individuals when the buccinator contracts. This appears as a "dimple" and is highly variable in form. The buccinator is a significant muscle in food processing in that it compresses the cheeks and lips against the teeth, thus positioning food for efficient chewing. The compression is also important in producing blowing actions, such as in blowing a horn." 1) Using context clues from the passage above, what is definition of decussate? How does this relate to dimples? 2) Your child has been constantly practicing trumpet for the band throughout middle school and tells you they want to become a professional trumpet player when they grow up. Unfortunately, in their freshman year of high school, they suddenly begin having difficulties playing. The doctor diagnoses damage to the orbicularis oris, which can be repaired throughh surgery. Your child now wants to know all about the muscles they use to play the horn. How do you explain them? Be sure to explain the locations of key bones and what a sphincter muscle is. 3) Think like a doctor: A parent brings their seven year old into the clinic with a swollen check and the child tells you it hurts to eat. Upon questioning the parent, you find that they are an anti-vax family. You know that one of the most common causes of inflammation of the parotid gland in children under 15 is mumps. You test for the virus and confirm the diagnosis. The parent wants to know why the child is having trouble eating and seems to be having trouble understanding your explanations. How do you calmly and clearly explain the location and role of the parotid gland and why inflammation might cause pain when chewing?
