  1. Defend or Refute. A plasma membrane is a key regulator for homeostasis of a liver cell  (hepatocyte) but not an osteocyte.
    Refute. Plasma membrane is a key regulator for homeostasis of all cells as it controls the flow in and out of the cell.

  8. Excluding erythrocytes and neurons, consider tissue in a livestock. Defend inclusion of the word plasma in plasma membrane.
    The plasma membrane is fluid and flexible, and can change shape and allows a flow in and out of the cell.

  16. Define Serosa including at least two structural features of serosa. Excluding functions.
    • Single cell thickness.
    • Avascular.
  17. What are the functions of a serosa membrane.
    • Lubricate organ to prevent adhesion.
    • Start of lymph system.
  18. What is the serous membrane for the Heart and Spinal Cord?
    Pia Mater
  19. What is the serous membrane for the heart?
    pericardium
  20. What is the serous membrane for the lungs?
    Pleura
  21. What is the serous membrane for the internal abdominal muscle kidney and reproductive system?
    Parietal Peritoneum
  22. What is the serous membrane for the digestive system liver and spleen?
    Visceral Peritoneum
  23. What is the serous membrane for the intestines?
    Mesentary Connective Peritoneum
  24. What is the serous membrane that stores fat?
    Omental Connective Peritoneum.
  25. Describe the events that would result in an umbilical hernia.
    The parietal peritoneum does not close adequately after birth and the intestine moves from the abdomen into the peritoneal cavity.
  26. Consider Longitudinal growth of bone. Name two cells that exert an active role in this process and describe functions for each.
    • Chondrocyte- Parent cells for cartilage.
    • Osteoblast- Calcifies matrix and becomes incorporated into bone as an osteocyte.
  27. Consider Longitudinal growth of bone. Describe the effects of thyrocalcitonin in osteogenesis.
    it helps with the incorporation of calcium into the inter-cellular matrix.
  28. Consider Longitudinal growth of bone. Defend or Refute. Osteolysis exerts a critical effect during appositional growth of bone. Explain.
    DEFEND. Osteolysis creates grooves for periosteum and endosteum to fold in and bring osteoblasts for osteogenesis.
  29. Name four distinct components of the axial skeleton.
    • Skull
    • Vertabrea
    • Ribs
    • Sternum

    Dorsal sacrum, and ventral pubis
  34. Part of a breeding soundness or prebreeding exam for a heifer might include measuring area of the pelvic canal. What anatomical landmarks are used to measure horizontal dimension?
    Laef and Right shaft of ilium
  35. Part of a breeding soundness or prebreeding exam for a heifer might include measuring area of the pelvic canal. Define and describe the broad ligament.
    it is the connective peritoneum that supports the reproductive tract.
  36. Part of a breeding soundness or prebreeding exam for a heifer might include measuring area of the pelvic canal. Defend or Refute. Within the anterior and posterior appendicular skeleton, most joints are synovial. Explain.
    In limbs, most joints have a cavity, which means they are synovial.
  37. Part of a breeding soundness or prebreeding exam for a heifer might include measuring area of the pelvic canal. What aspect of the skeleton are reference points or locations to score body condition in beef cattle.
    • Ribs
    • Lumbar vertebrae

  39. Defend or Refute. If the bone was the rib, the layers would be exactly the same as in the arrow question. Explain.
    DEFEND. All bones have the same layers.
  40. At any instant of time, name the living cells that are inside compact bone of a live animal.

    • Erythrocyte (RBC)
    • White Blood Cells
  41. For homeostasis of calcium, what are the sources of calcium that might be used to sustain homeostasis? For each source describe any active processes required to retrieve the calcium.
    • Calcium in blood is where homeostasis is determined as it is not a source.
    • Muscle - Calcium is readily available to blood
    • Bone - Calcium must be dissacociated from bone with digestion (osteolysis)
    • Diet - With help from Vitamin D3, calcium is absorbed from diet into the blood.
