    Hormones responsible for the homeostasis of blood calcium levels are PTH and

    • Calcetonin

    • Serotonin

    • Myosin

    • Acetylcholine

    Correct Answer
    A. Calcetonin
    Explanation
    Calcetonin is the correct answer because it is a hormone responsible for the homeostasis of blood calcium levels. It works by inhibiting the activity of osteoclasts, which are cells that break down bone tissue and release calcium into the bloodstream. This helps to lower blood calcium levels and maintain a balance in the body. PTH, or parathyroid hormone, is another hormone involved in the regulation of blood calcium levels, but it works by increasing the activity of osteoclasts to release more calcium into the bloodstream.

    Rate this question:

  • 22. 

    Slightly moveable joints are called...

    • Gomphosis

    • Diarthroses

    • Synarthroses

    • Amphiarthroses

    Correct Answer
    A. Amphiarthroses
    Explanation
    Amphiarthroses refers to slightly moveable joints. This type of joint allows for limited movement and is characterized by the presence of cartilage or fibrous tissue between the bones. Unlike synarthroses (immovable joints) and diarthroses (freely movable joints), amphiarthroses provide some flexibility and allow for small movements, such as in the vertebral column or the pubic symphysis. Gomphosis, on the other hand, is a type of joint found only in the teeth, where they are firmly anchored in the sockets.
