CDS Anatomy & Physiology Fundamentals 4

Question 1

Which of the following best describes the role of the thalamus in sensory processing relevant to pain management in disability care?

Accepted Answer

It acts as a relay station routing sensory signals to the appropriate cortical areas

Answer

The thalamus is the primary sensory relay center of the brain, routing incoming sensory information including pain signals to the relevant cortical regions.

Question 2

When documenting a client's muscle weakness as 'flaccid paralysis,' the disability specialist understands this indicates damage to the:

Accepted Answer

Lower motor neurons in the spinal cord or peripheral nerves

Answer

Flaccid paralysis results from lower motor neuron damage, causing loss of muscle tone, reflexes, and voluntary movement in the affected area.

Question 3

The rotator cuff is a group of four muscles that stabilize the shoulder joint. Which of the following is NOT one of the rotator cuff muscles?

Accepted Answer

Deltoid

Answer

The deltoid is a large shoulder muscle but is not part of the rotator cuff; the four rotator cuff muscles are supraspinatus, infraspinatus, teres minor, and subscapularis.

Question 4

A disability specialist is reviewing a client's chart noting 'T10 complete SCI.' Which functional level should the specialist expect the client to have?

Accepted Answer

Full upper extremity function with paraplegia below the umbilicus

Answer

A complete T10 spinal cord injury results in full upper extremity function but paraplegia with loss of sensation and motor function below approximately the umbilicus.

Question 5

The process by which neurons strengthen their synaptic connections based on repeated activation is known as:

Accepted Answer

Long-term potentiation

Answer

Long-term potentiation (LTP) is the strengthening of synaptic connections through repeated stimulation, forming the cellular basis of learning and neuroplasticity after injury.
