The arm is known as the_______region; the neck is known as the _______ region.
a. Otic; axillary
b. Antebrachial; dorsal
c. Brachial; cervical
d. Sural; crural

Verified step by step guidance

1. Step 1: Understand the question. The problem is asking for the anatomical terms used to describe the arm and the neck regions of the body.
2. Step 2: Recall the anatomical terminology. The arm is referred to as the 'brachial' region in anatomy, and the neck is referred to as the 'cervical' region.
3. Step 3: Review the options provided in the question. Match the correct anatomical terms to the regions described: a. Otic (ear); axillary (armpit), b. Antebrachial (forearm); dorsal (back), c. Brachial (arm); cervical (neck), d. Sural (calf); crural (leg).
4. Step 4: Identify the correct option by matching the terms to the arm and neck regions. The correct terms are 'brachial' for the arm and 'cervical' for the neck.
5. Step 5: Conclude that the correct answer is option c: Brachial; cervical.

Key Concepts

Anatomical Regions

Anatomical regions are specific areas of the body that are defined for the purpose of study and communication in anatomy. Each region has a designated name that helps identify its location and associated structures. For example, the 'brachial' region refers to the upper arm, while the 'cervical' region pertains to the neck.

Terminology in Anatomy

Anatomical terminology is a standardized language used to describe the locations and relationships of body parts. This terminology includes terms like 'proximal' and 'distal' to indicate relative positions, as well as specific regional terms such as 'axillary' for the armpit area. Understanding this terminology is crucial for accurately identifying and discussing body regions.

Regional Anatomy

Regional anatomy focuses on specific areas of the body and the structures contained within those areas. It allows for a detailed examination of the relationships between different organs and tissues in a particular region. For instance, studying the brachial region involves looking at the muscles, nerves, and blood vessels that are found in the arm.
