Ch 25 Neurological

Question 1

Upper motor neurons

Answer 1

• descending motor fibres that are located within the CNS

Question 2

Lower motor neurons

Answer 2

• mostly in the PNS

- movement must be translated into action by lower neurons

Question 3

5 parts of deep-tendon reflex arc

Answer 3

1. an intact sensory nerve (afferent)
2. a functional synapse in the cord
3. an intact motor nerve fiber (efferent)
4. neuromuscular junction
5. a competent muscle

Question 4

Parts assessed routinely for people being monitored for neurological deficit

Answer 4

1. LOC
2. Motor function
3. Pupillary
4. Vitals

Gait patterns: Steppage

Answer 7

slapping quality

Question 8

Gait patterns: Waddling

Answer 8

weak hip muscles, hip drops

Question 9

state the types of reflex response you would expect to see with an upper motor neuron lesion versus a lower motor neuron lesion
