    Incorrect

    • Where would one find pericytes around endothelial cells?

      Your Answer: Pre-capillary venules

      Correct Answer: Post-capillary venules

      Explanation:

      Pericytes release a wide variety of vasoactive agents which regulate the flow through the junction between endothelial cells.

    Incorrect

    • Which of the following statements is the most characteristic of primary Raynaud's phenomena?

      Your Answer: Anti-nuclear antibody is positive in 70% of cases

      Correct Answer: Fingers are symmetrically involved during an attack

      Explanation:

      A typical attack may last less than an hour but can also persist for longer. In primary Raynaud’s, attacks are more likely symmetric, episodic, and without evidence of peripheral vascular disease. Patients more commonly have a negative ANA and normal inflammatory markers. There should be no evidence of tissue gangrene, digital pitting, or tissue injury in primary Raynaud’s. In contrast, patients with secondary Raynaud’s will describe attacks that are more frequent, painful, often asymmetric and may lead to digital ulcerations.

    Incorrect

    • The main efferent input of the posterior pituitary gland comes from:

      Your Answer: Paracrine hormones secreted from the hypothalamus via pituitary portal veins

      Correct Answer: Paracrine hormones secreted from the hypothalamus via axons.

      Explanation:

      The posterior pituitary or neurohypophysis consists of a collection of axonal projections emerging from the hypothalamus. It releases hormones directly from these axonal endings into circulation; these hormones are oxytocin and vasopressin.

    • Where is thyroglobulin produced?

      Your Answer: Colloid

      Correct Answer: Thyrocytes

      Explanation:

      Thyroglobulin, or Tg, is a protein that functions as the precursor to thyroid hormones. It is synthesized by thyrocytes and then secreted into the colloid. It also functions as a negative-feedback regulator of thyroid hormone biosynthesis.
