Question

the structure of the body is divided into the following:

cells, tissue, genes, systems
cells, tissues, organs, systems
cells, cartilage, genes, organs
cells, chromosomes, genes, tissues, muscles
cervical, thoracic, lumbar, sacral, coccygeal

Explanation:

Identify the core question

The question asks for the standard structural divisions or levels of organization of the human body.

Analyze the levels of organization

Using Anatomical Terminology, the human body is organized hierarchically from the simplest building blocks to the most complex organism. The standard biological levels of structural organization are:

1. Chemical level (atoms and molecules)
2. Cellular level (cells)
3. Tissue level (tissues), which is studied in Histology Terminology
4. Organ level (organs)
5. System level (organ systems)
6. Organismal level (the whole body)

Evaluate the given options

• cells, tissue, genes, systems: Incorrect. Genes are molecular components within cells, not a distinct level of structural organization between tissues and systems.
• cells, tissues, organs, systems: Correct. This sequence accurately represents the progressive levels of structural organization in the body.
• cells, cartilage, genes, organs: Incorrect. Cartilage is a specific type of tissue, and genes are genetic material, making this list non-sequential and incomplete.
• cells, chromosomes, genes, tissues, muscles: Incorrect. Chromosomes and genes are sub-cellular structures, and muscles are a specific type of tissue/organ.
• cervical, thoracic, lumbar, sacral, coccygeal: Incorrect. These are regions of the spinal column, not the general structural levels of the body.

Select the correct option

The second option, "cells, tissues, organs, systems," is the correct sequence showing how the body is structurally divided.

Answer:

• (A) cells, tissue, genes, systems
• (B) cells, tissues, organs, systems (Correct answer)
• (C) cells, cartilage, genes, organs
• (D) cells, chromosomes, genes, tissues, muscles
• (E) cervical, thoracic, lumbar, sacral, coccygeal
