What this covers

Sample questions

Which bone cell breaks down bone tissue during remodeling?

  1. Osteoblast
  2. Osteocyte
  3. Chondrocyte
  4. Osteoclast
Show the answer

D. Osteoclast

Osteoclasts resorb (break down) bone. Osteoblasts are the easy mix-up: they build new bone matrix. Osteocytes are mature cells that maintain bone, and chondrocytes are cartilage cells.

Which type of muscle tissue is striated and involuntary?

  1. Smooth muscle
  2. Skeletal muscle
  3. Voluntary muscle
  4. Cardiac muscle
Show the answer

D. Cardiac muscle

Cardiac muscle has striations but is not under conscious control. Skeletal muscle is also striated, which makes it tempting, but it is voluntary. Smooth muscle is involuntary and has no striations.

Which neurotransmitter is released at the neuromuscular junction to trigger skeletal muscle contraction?

  1. Acetylcholine
  2. Serotonin
  3. Dopamine
  4. Norepinephrine
Show the answer

A. Acetylcholine

Motor neurons release acetylcholine at the neuromuscular junction. Norepinephrine is the tempting choice because it is a major neurotransmitter of the sympathetic system, but it does not act at the skeletal muscle motor end plate.
