The cranial nerves that have neural connections with the tongue include all except the
a. facial
b. trigeminal
c. trochlear
d. glossopharyngeal

c. trochlear

Explanation:

Tongue is a muscular organ essential for tasting, chewing, swallowing and speech. It is innervated by various cranial nerves.

CRANIAL NERVE V (TRIGEMINAL NERVE)

It is responsible for conducting sensory sensations (apart from taste) from the anterior 2/3rds of tongue.

CRANIAL NERVE VII (FACIAL NERVE)

It is responsible for the sensation of taste from anterior 2/3rds of tongue.

CRANIAL NERVE IX (GLOSSOPHARYNGEAL NERVE)

It is responsible for general sensation and gustatory perception (taste) from the posterior 1/3rd of tongue.

CRANIAL NERVE XII (HYPOGLOSSAL NERVE)

It is responsible for the movement of tongue.

QUESTION:

c. trochlear

This is the correct answer as this cranial nerve does not have neural connections with tongue. Trochlear nerve is cranial nerve IV and is responsible for innervating superior oblique muscle in the eye and controls eye movements.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

answer is d hope this
