Answer and explanation;
1) CN III (Oculomotor) -Ciliary muscles
2) CN VII (Facial) -Lacrimal glands
3) CN X (Vagus) -Thoracic and abdominal viscera
4) Pelvic Splanchnic Nerves -Most pelvic viscera
Explanation;
The oculomotor nerve is the third of 12 pairs of cranial nerves in the brain. This nerve is responsible for eyeball and eyelid movement.
-Facial nerves; Sensory fibres are concerned with taste via the taste buds at the front of the tongue. Motor fibres control secretion of tears via the lacrimal glands and saliva via the sublingual salivary glands as well as facial expressions via some of the muscles of facial expression.
Vagus nerve; Stimulates voluntary muscles that effect swallowing, coughing and speech (conscious control).Stimulates the contraction and relaxation of smooth muscle in the gastrointestinal tract. (unconscious control).
Given what we know, we can confirm that the statement in the question is in fact true, by the end of the eighth week, the embryo is only 1 inch long and weighs just 1 gram.
<h3>What else do we know about the
embryo in this time frame?</h3>
During the first eight weeks, the embryo undergoes many changes. At this time:
- The legs and arms have formed.
- The fingers and toes are beginning to develop.
- It begins to be called a fetus.
- It is developing the lungs and lymphatic system.
- and much more.
Therefore, we can confirm that the statement that by the end of the eighth week, the embryo is only 1 inch long and weighs just 1 gram, is in fact true.

<span>since the vast majority have never been studied in the laboratory and have only been detected by analysis of their nucleic acids in samples from the environment. Although archaea have, in the past, been classed with bacteria as prokaryotes, this classification has been described as outdated, since it fails to distinguish between the three very distinct domains of life.</span>
