Look Out Below: A Case Study on Bone Tissue Structure and Repair An elderly patient arrived at the emergency room unconscious after an accident in which a heavy overhead shelf struck her arm. Upon auscultation, a large open wound on her arm was evident with what appears to be bone tissue sticking out of the skin. She also has bruises covering her left shoulder, left wrist, and lower back. To determine the extent of her injuries the patient undergoes several x-rays, which reveal the following:
5. Most connective tissue, including bone, is highly vascular. Which anatomical structures in the patient’s compact bone house blood vessels?
6. What term is used to describe the addition of new bone tissue? Identify which bone cell is responsible for this process and explain how it occurs.
7. What makes up the organic and inorganic portions of the bone’s extracellular matrix (ECM)? 8. Describe the structure of an osteon.
Discussion:
Further diagnostic tests on the patient revealed a lack of estrogen and calcium. Elaborate on how these factors may have made the injury worse. In normal conditions, what would be the response to falling calcium levels? Post your response and respond to two of your classmates using at least 3-5 sentences to receive full credit (10 points).

What advantages might there be for infants to be born with more nerve cells (neurons) than they actually need or use?
Think of language, for example. When a human infant is born, he/she has to ability to learn to speak any language that humans speak however, as the infant grows and is exposed to one predominant language in his/her home, this becomes the language that the child learns to speak. The child sounds like other native speakers of his/her language. Later, if the person decides to take a foreign language in high school, he/she will most likely sound like a foreign speaker when speaking the newly learned language or for some students, learning a foreign language is a rather difficult task.
In later life, if a person has a cerebral vascular accident (CVA) or what people in the community call "a stroke", and this person speaks more than one language, after the CVA, she/he will more likely be able to speak basically the first language learned. The second, third, etc. languages the person learned, will typically be very difficult for this person.
Example: Elisita was born into a Spanish speaking family in Mexico . Her parents spoke only Spanish in the home, as did Elisita's siblings and other relatives. Very few of Elisita's neighbors spoke English therefore Elisita was never exposed to the sound of English as a baby/toddler. When Elisita was two years of age, her family migrated to Chicago, Illinois. At age five, Elisita was enrolled in a public school where she was exposed to the English language at least six hours per day. She learned to speak English quite well. When Elisita was age sixty-nine, due to uncontrolled high blood pressure, she suffered a cerebral vascular accident. With some speech therapy she was able to recover a great deal of her Spanish language skills, but her ability to speak English was impaired.

Please answer all parts of this question for both parts!!
Prompt:
In our study of the skeletal system this week it should be readily apparent to you how important synovial joints are in the normal function of the human body. This week you will pick two synovial joints to discuss. Pick one from each category below. For each selected joint you should provide the following information: the movements that are possible at that joint (use appropriate anatomical terminology), identification of the bones, bony features, and soft tissue structures (ligaments, tendons) that are involved in that joint, and a brief discussion of the associated clinical correlation provided for each. Your discussion of the clinical correlation MUST include a summary of the expected functional deficit that would be produced by the condition.
Choose two of the following synovial joints to discuss, one from each list:
GROUP 1
Knee - ACL tear
Hip - Labral tear
Elbow - “Nursemaid’s” elbow
Shoulder - Rotator cuff injury
GROUP 2
Metacarpal-phalaengeal joint - Osteoarthritis
Thumb - “Texter’s thumb”
Ankle - Ankle fracture
Jaw - TMJ syndrome
