A 26-year-old male went to the dentist to have a decayed mandibular 3^rd molar (wisdom) tooth extracted. The dentist explained he would likely experience considerable pain with the removal of the tooth and informed the patient that he was going to inject a “local” anesthetic to desensitize the tooth and associated soft tissues. When agreeing to the extraction, the patient asked that plenty of anesthetics be given because he was extremely sensitive to pain. The dentist inserted the needle through the mucous membrane on the inside of the patient’s mouth, where the needle came to rest near the lingula, a bony projection on the medial surface of the ramus of the mandible. In a few minutes, the patient verbalized that his gum, lip, chin, and tongue on the affected side were numb (anesthetized).

During the extraction procedure, the patient stated he felt pain; the dentist injected more anesthetic. The tooth was removed without further incident. As the patient was preparing to leave, he happened to look in the mirror. He was surprised to find

that he was unable to close his eye and lips on the affected side and that his mouth sagged on this side, particularly when he attempted to expose his teeth. He also noted that his ear lobule was numb. When he reported these unusual symptoms, the dentist explained that because of the large amount of anesthetic injected, other nerves in addition to those that supply the teeth had been anesthetized. He assured the patient that these effects would disappear in 3 to 4 hours.

1. State the name of the nerve supplying the mandibular molar and premolar teeth.

2. Why were the patient’s chin and lower lip also anesthetized?

3. When anesthetizing this nerve, what other nerve might be affected? Why was the tongue on the injected side also anesthetized?

4. What probably caused the patient’s facial paralysis and loss of sensation in his ear lobule?

Tissue perfusion includes oxygen and nutrient movement into all capillaries and waste and carbon dioxide movement out of capillaries to body tissues.

Group of answer choices

tunica interna (intima)
[ Choose ] This muscular layer is only found in capillaries this layer has elastic fibers & smooth muscle, which is regulated by the sympathetic nervous system this thick outer layer has fibers (elastic & collagen) that run parallel to the the vessel this layer is the only one found in all vessels; made up of simple squamous epithelium

tunica media
[ Choose ] This muscular layer is only found in capillaries this layer has elastic fibers & smooth muscle, which is regulated by the sympathetic nervous system this thick outer layer has fibers (elastic & collagen) that run parallel to the the vessel this layer is the only one found in all vessels; made up of simple squamous epithelium

tunica externa (adventitia)
[ Choose ] This muscular layer is only found in capillaries this layer has elastic fibers & smooth muscle, which is regulated by the sympathetic nervous system this thick outer layer has fibers (elastic & collagen) that run parallel to the the vessel this layer is the only one found in all vessels; made up of simple squamous epithelium

Question 8

What happens to blood pressure as blood moves away from the heart?

Group of answer choices

pressure decreases

pressure is held steady

pressure increases

Question 9

Please match the following vessels to their description:

Group of answer choices

arteries
[ Choose ] large lumens and valves characterized these vessels elastic conducting and muscular distributing vessels carry blood away from the heart major location of gas and nutrient exchange allow for alternative routes of blood flow

veins
[ Choose ] large lumens and valves characterized these vessels elastic conducting and muscular distributing vessels carry blood away from the heart major location of gas and nutrient exchange allow for alternative routes of blood flow

anastomoses
[ Choose ] large lumens and valves characterized these vessels elastic conducting and muscular distributing vessels carry blood away from the heart major location of gas and nutrient exchange allow for alternative routes of blood flow

Group of answer choices

True

False

Below are two diagrams of the anterior abdominal wall, depicting the relationships of the aponeuroses and musculature, either superior or inferior to the arcuate line. Your task is to download these diagrams, correctly identify BOTH images as being superior or inferior to the arcuate line, and annotate (label) the muscles and aponeuroses of the abdominal wall muscles in BOTH images.

Your diagram should be labeled, and should include arrows. Labels should only include the structure being denoted, not a sentence or more.

no extra information necessary, i.e. do not write paragraphs – all reasoning should be inferred through the labelling and arrows.

*can be drawn by hand (must be neat) OR a stylus OR using .ppt tools, Canva.com, etc.

ensure Accurate indication of images as superior and inferior to arcuate line and Correct identification of abdominal wall muscles

Business strategy

1. Identify or define the corporation’s vision based on the definitions in the textbook and using evidence from the research. Then, discuss if this vision may fail. Use the reasons for the vision to fail discussed in the textbook. Include all reasons in the discussion.
2. Identify or define the corporation’s mission based on the definitions in the textbook and using evidence from the research. Then, discuss if this mission is good and effective. Use the discussion in the textbook about the elements of a good and effective mission statement.  Include all elements in the discussion.
3. Create four strategic objectives for the corporation based on the criteria for creating meaningful objectives (SMART goals) in the textbook and using evidence from the research.

External environment

1. Identify three dimensions of the general environment, from those in the textbook, important for this corporation. Then, mention an example of each dimension based on the research, and explain why they are relevant.
2. Describe the industry in which your corporation operates using the SIC code. Then, identify forces of Porter in the industry of the company that you have selected and determine the level of power of each force (which force appropriates most of the industry profit?). Finally, discuss the level of power of each force using examples and/or evidence.

Integration

1. Create a SWOT matrix for the corporation. Provide examples or evidence of strengths, weaknesses, opportunities, and threats.
