Justin Partridge Amanda Palffy Heather Quadir 10/7/10 Problem Set – Connective Tissue 1. When a person reacts to an allergen, IgE antibodies are secreted from lymphocytes. The IgE antibody binds to receptors on mast cells, causing degranulation, synthesis of leukotirenes, and the release of histamines. This leads to increased mucous production, bronchial constriction, and blood vessel dilation. Fluid will, therefore, concentrate in the nasal cavity and there will be a buildup of mucous causing the “stuffed up” symptom. 2. The reserves of white fat would remain around the body’s core and vital organs. This is because white fat is heavily vascularized and functions to store energy, insulate, and pad the body. The vital organs are most important and therefore it would be most crucial to maintain energy (breakdown of lipid droplet into fatty acids), heat, and padding around them. 3. Osteoclasts function to degrade bone. As new bone grows osteoclasts breakdown old bone in order to maintain space within the bone for bone marrow. Bone marrow is important because it creates erythrocytes in the blood and also produces immune cells for the body. If osteoclastes are defective, bone marrow will be reduced and production of erythrocytes and immune cells will be inhibited, resulting in fewer defenses against infection and anemia. 4. Normal bone lengthening takes place at the epiphyseal growth plate of long bones where a cycle of cartilage growth, matrix formation and calcification of cartilage occurs to successfully lengthen bones. This cellular cycle is known as endochondral ossification.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
