Answer: True
Explanation:
The corticospinal tract can be defined as the white matter motor pathway that starts with the cerebral cortex and terminates at the lower motor neuron of the spinal cord. This controls the movement of the trunk and limbs.
If the corticospinal tract is affected at any level above the medulla the voluntary control over the movements will be affected on the contra-lateral side of the body.
A threatened abortion is the potential problem.
<h3>What is threatened abortion?</h3>
The term "abortion" refers to the termination of a pregnancy before to 20 weeks of gestation. A threatening, inevitable, incomplete, full, septic, or missed abortion is one of the various forms of spontaneous abortion.
A threatened abortion is described by vaginal bleeding before 20 weeks of gestation in the presence of a positive urine and/or blood pregnancy test with a closed cervical os, without passage of sperm or eggs, and without signs of fetal or embryonic death.
The World Health Organization (WHO) defines a threatened abortion as open bleeding or pregnancy-related bloody vaginal discharge that occurs during the first half of the pregnancy without cervical dilatation.

The HPV vaccine primarily protects against strains #16 and #18.
Answer: #16 or #18
Answer:
The correct answer will be option B- enzymatic action of Acetylcholinesterase.
Explanation:
At the neuromuscular junction, the neurotransmitter acetylcholine is released which then binds to the receptor in motor-end plate causes depolarization of the membrane responsible for the release of Ca⁺² ions. These Ca⁺² ions control the contraction of the muscle by binding to troponin.
This mechanism of muscle contraction is blocked after the breakdown of the acetylcholine by the "enzyme acetylcholinesterase" which leads to the closure of the Na⁺ ion-channels. The closure of these channels slows down the depolarization in muscle fiber and thus blocks the pathway which leads to muscle relaxation.
Thus, Option-B is the correct option.
