Answer:

The correct answer is D. The seventh cranial nerve is the facial nerve.

Explanation:

The facial nerve is a mixed cranial nerve, that is, it contains both sensory and motor fibers, present in mammals including humans in which it forms the seventh cranial nerve. Being a cranial nerve, it emits two fibers, one that runs on the right side of the face and the contralateral on the left. It starts of the brain stem, just between the brainstem and the medulla and controls the facial expression muscles, as well as the taste in the previous two thirds of the tongue. It also supplies parasympathetic preganglionic innervation to various nerve nodes in the head and neck.

REY [17]

Answer:

Faith, according to the Bible, is not blind. More than half of the verses in the book of Hebrews are dedicated to explaining reasons and evidence to accept the new covenant in Jesus Christ. Nor is faith gullible, or senseless. Instead, godly faith is exemplified by trust. That trust is based on what we know of God, relying on Him for the things we do not know. In particular, godly faith looks forward, from an eternal perspective, and produces obedience, even in the face of hardship. God takes what we cannot see, or cannot understand, and uses it to make good on His word. Since faith relies on what we've seen of God, and trusts Him for the future, it becomes the "assurance of things hoped for, the conviction of things not seen" (Hebrews 11:1–3).
