Textbook Question

On what body surface is each of the following located: nose, calf of leg, ears, umbilicus, fingernails?

Verified step by step guidance

Step 1: Understand the concept of body surfaces. The human body is divided into anatomical regions and surfaces, such as anterior (front), posterior (back), lateral (side), and others. These terms help describe the location of structures relative to the body.

Step 2: Identify the location of the nose. The nose is located on the anterior surface of the body, specifically on the face.

Step 3: Determine the location of the calf of the leg. The calf is located on the posterior surface of the body, specifically on the back of the lower leg.

Step 4: Locate the ears. The ears are located on the lateral surfaces of the head, as they are positioned on the sides of the head.

Step 5: Identify the location of the umbilicus and fingernails. The umbilicus (navel) is located on the anterior surface of the body, specifically on the abdomen. Fingernails are located on the dorsal surface of the fingers, which is the back side of the fingers.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Anatomical Terminology

Anatomical terminology is a standardized language used to describe the locations and relationships of body parts. It includes terms that specify regions, directions, and positions, such as 'anterior' (front) and 'posterior' (back). Understanding this terminology is essential for accurately identifying the body surfaces where specific structures, like the nose or ears, are located.

Body Regions

The human body is divided into various regions that help in identifying the location of organs and structures. Key regions include the head, neck, trunk, and limbs. Recognizing these regions allows for a clearer understanding of where specific body parts, such as the umbilicus or calf of the leg, are situated in relation to one another.

Surface Anatomy

Surface anatomy refers to the study of the external features of the body and how they relate to the underlying structures. It involves identifying landmarks on the skin that correspond to deeper anatomical structures. This concept is crucial for locating features like fingernails and understanding their position on the body surface.

Textbook Question

A nurse informed John that she was about to take blood from his antecubital region. What part of his body was she referring to? Later, she came back and said that she was going to give him an antibiotic shot in the deltoid region. Where on his body did he get the shot? Before John left the office, the nurse noticed that his left sural region was badly bruised. What part of his body was black and blue?
