Read the following Case Study and answer the questions based on the information.
History of Present Illness: The patient has been noted to have some bright, red bleeding intermittently for approximately 8 months, initially presumable of a hemorrhoidal basis. She recently has had intensification of the rectal bleeding but no weight loss, anorexia, or obstructive pain. No significant diarrhea or constipation. Some low back pain, probably unrelated. Recent colonoscopy by Dr. Scoma revealed a large sessile (attached by a broad base) polyp, which was partially excised at the 20 cm level, showing infiltrating adenocarcinoma at the base. The patient is to enter the hospital at this time, after home antibiotic and mechanical bowel prep, to undergo sigmoid colectomy and possible further resection.

B. Swollen rectal veins
C. Ulcerative colitis
D. Malignant tumor of the colon
3. What procedure did she have recently that diagnosed her condition?
A. Visual examination of her large intestine
B. Removal of her sigmoid colon
C. Low anterior resection of the large intestine
D. Hemorrhoidectomy

Benzodiazepines are positive allosteric modulators at the GABA-A receptor. a) Describe how positive allosteric modulators affect receptor function. b) Discuss the mechanism of action of benzodiazepines and their effect on central nervous system (CNS) activity. c) GABA is also an agonist at GABA-B receptors, which are G protein coupled receptors that couple to Gi. Explain the signalling pathways that will be activated when GABA binds to the GABA-B receptor.

Factors increasing mobility of the joint:
- Bones:
- Capsule:
- Synovial membrane & bursae:
- Muscles:
- Accessory joints:
- Scapulo-humoral rhythm:
Factors maintaining stability of the joint:
- Labrum:
- Rotator cuff:
- Ligaments:
- Tendons:
When you talk about each factor, please focus on its role in either mobility and stability. For example, you don't have to describe the attachment of the capsule and the ligaments, but what is specific in the capsule to increase mobility, and how each ligament supports and stabilizes the joint. Another example about the rotator cuff muscles, you don't have to describe each muscle in detail, but how they are the most important factor in maintaining the stability of the joint.

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).
