Mechanoreceptors are receptors that can respond to which of the following stimuli?

• Shocks

• Intense heat (above 45°C)

• Irritating chemical substances

• All of the above.

If a gymnast is rotating in the air (without touching the mat) wants to orient themselves, which type of receptors do they use?

• Joint receptors.

• Vestibular receptors.

• Cutaneous receptors.

• Muscle receptors.

The vestibular system that is responsible of maintaining bodily balance is located in:

• The parietal lobe

• The inner ear

• The outer ear

• The brain stem

The connection between neurons, allowing the transfer of information from one to the other is called

• Myelin

• Action potential

• Synapse

• Neurotransmitter

What are the benefits of proprioception exercises

• Prevention of joint and ligament injuries

• Improvement of coordination and balance

• Improvement of muscle strength

• All of the above

• None of the above, there are no proprioception exercices

Articular receptors are:

• The nociceptors

• Ruffini, Pacini, and Golgi receptors

• Detectors for head movement

• None of the above

Cones are:

• Present at the periphery of the retina

• Very sensitive to high light intensities

• Allow to distinguish shades of gray

• All of the above

Choose the correct information

• The sensory receptors are stimulated by the stretching of the muscle itself

• The sensory receptors are stimulated by the contraction of the muscle itself

Sensory neurons:

• Transmit information from the sensory receptors to the CNS

• Transmit action potentials from the CNS to the skeletal muscle

• Transmit information from the PNS to the sensory receptors

Concerning intrafusal fibers

• They are responsible for generating muscle force

• They have a sensory role, informing the CNS about muscle lenght

• Both options are correct

• None of the above
