To test for stereognosis you would
- A. Have the person close his or her eyes, then raise the person's arm and ask the person to describe its location.
- B. Touch the person with a tuning fork
- C. Place a coin in the person's hand and ask him or her to identify it.
- D. Touch the person with a cold object
Correct Answer: C
Rationale: Stereognosis is the ability to perceive and recognize the form of an object using touch.

This assesses the sensory cortex's ability to interpret tactile sensations.
Compared with myelinated nerve fibres, non-myelinated nerve fibres:
- A. have a higher threshold for stimulation
- B. have a longer refractory period
- C. transmit impulses at a lower frequency
- D. all above
Correct Answer: D
Rationale: Non-myelinated nerve fibers have a higher stimulation threshold, longer refractory period, and lower impulse transmission frequency compared to myelinated fibers. These differences are due to the lack of saltatory conduction in non-myelinated fibers.
What part of a neuron is responsible for receiving information?
- A. axon
- B. terminal bre
- C. dendrite
- D. myelin sheath
Correct Answer: C
Rationale: Dendrites are the part of a neuron responsible for receiving information from other neurons. They are branched structures that extend from the cell body and contain receptors for neurotransmitters. When neurotransmitters bind to these receptors, they generate electrical signals that travel toward the cell body, initiating communication between neurons. Dendrites play a crucial role in integrating incoming signals and determining whether the neuron will fire an action potential.

- D. Vertebrae become more compressed with thinning of intervertebral discs
