Which statement about muscle contraction is correct?
Iron and fats bound to actin play a critical role in muscle cell contraction and relaxation.
Thin filaments stretch, whereas thick filaments stay the same length.
A typical muscle fiber at rest contains enough ATP for millions of contractions.
Thick filaments stretch, whereas thin filaments stay the same length.
Neither thin nor thick filaments change in size, although the area of overlap between them increases.
Which of the following is a true statement regarding a reflex response?
It is a conscious response to painful stimuli.
The response is carried out solely by the peripheral nervous system
It requires a sensory neuron, an interneuron, and motor nerves.
Pain receptors in the skin send a message to the brain to initiate motor movement.

While sitting quietly watching television, you suddenly hear the sound of glass breaking. Which of the following is responsible for your resulting rapid heartbeat?
ANS - autonomic nervous system
PNS = peripheral nervous system
parasympathetic division of the ANS
central nervous system (CNS)
sympathetic division of the ANS

The gray matter of the cerebral cortex, where most higher-level thinking occurs, is composed mostly of __________.
myelinated axons of neurons
cranial nerves
sensory neuron cell bodies

"Volume is determined by the amplitude of a sound wave. The greater the amplitude of a sound, the more vigorous the vibrations of the fluid in the cochlea. Prolonged exposure to very loud sounds can irreversibly damage the hair cells of the cochlea."
Sitting too close to the amplifiers at a concert may
damage the pinnae
affect the alignment of the semicircular canals
cause the hammer to damage the anvil and stirrup bones
cause fluid leakage from the cochlea
damage the hair cells in the ears
