Answer 1

Explanation:

1. Thiamin deficiency (causing beriberi) is most common among people subsisting on white rice or highly refined carbohydrates in developing countries and among alcoholics. Symptoms include diffuse polyneuropathy, high-output heart failure, and Wernicke-Korsakoff syndrome.

2. The one word of 'the constriction between crown and root' is the neck. The neck of the tooth is covered with the gum and a crown. Teeth help u to chew and bite the food and they also help in shaping various sounds and forming the words.

3. The atlas is the first cervical vertebra and articulates with the occiput of the head and the axis (C2). It differs from the other cervical vertebrae in that it has no vertebral body and no spinous process. Instead, the atlas has lateral masses which are connected by an anterior and posterior arch.
