Question

match the nerve tracts in column a with the descriptions in column b. place the letter of your choice in the space provided.
column a
a. corticospinal
b. fasciculus gracilis
c. lateral spinothalamic
d. posterior spinocerebellar
e. reticulospinal
column b

1. ascending tract to the brain to interpret touch, pressure,

and body movements

1. descending tract whose fibers conduct motor impulses to

sweat glands and muscles to control tone

1. descending tract whose fibers conduct motor impulses to

skeletal muscles

1. ascending tract to the cerebellum necessary for

coordination of skeletal muscles

1. ascending tract to the brain to give rise to sensations of

temperature and pain

Explanation:

• Corticospinal (a): It is a descending tract. Its main function is to conduct motor impulses to skeletal muscles.
• Fasciculus gracilis (b): An ascending tract. It transmits information related to touch, pressure, and body movements to the brain for interpretation.
• Lateral spinothalamic (c): An ascending tract. It is responsible for carrying sensations of temperature and pain to the brain.
• Posterior spinocerebellar (d): An ascending tract. It is necessary for the coordination of skeletal muscles as it sends information to the cerebellum.
• Reticulospinal (e): A descending tract. Its fibers conduct motor impulses to sweat glands and muscles to control tone.
